Items & Item Triggers

This tutorial was written for people who want to fill their knowledge from alot of things about items and using item triggers. I will be covering things relating to items in the Object Editor, item triggers in general, and also item recipes specifically, for all those people who wanted to know how to create them.

Please note that to be able to understand the full concepts of this tutorial, you will need some decent knowledge in GUI of how to use variables, custom scripts, and have some basic understanding of how to use the Items tab of the Object Editor.

Let's begin!

Chapter 1

1. Creating Items

What could this function be used for?
-Creating a key to open a gate
-Creating an item when a hero uses an ability

Lets start our first item trigger, using the simple event "Unit enters region" and the basic action "Item - Create":

Code:

Creating Items 1
    Events
        Unit - A unit enters Region <gen>
    Conditions
    Actions
        Set TempPoint = (Center of Region <gen>)
        Item - Create Gate Key at TempPoint
        Custom script:    call RemoveLocation(udg_TempPoint)

Next, we will be using the following trigger to understand how to create an Item at a point after a hero uses an ability (note that we want to use a "clean" trigger by preventing memory leaks. You can make the ability specific by adding in an ability comparison condition):

Code:

Creating Items 2
    Events
        Unit - A unit Starts the effect of an ability
    Conditions
    Actions
        Set TempPoint = (Position of (Triggering unit))
        Item - Create Claws of Attack +15 at TempPoint
        Custom script:   call RemoveLocation(udg_TempPoint)

For our next trigger, we will be creating an item at the position of a dead destructible.
This trigger could be useful for a custom melee map that when a destructible dies, players can acquire the destructible's soul and sell it for 50 gold or something:

Code:

Creating Items 3
    Events
        Time - Every 1.00 seconds of game time
    Conditions
    Actions
        Destructible - Pick every destructible in (Playable map area) and do (Actions)
            Loop - Actions
                If (All Conditions are True) then do (Then Actions) else do (Else Actions)
                    If - Conditions
                        ((Picked destructible) is dead) Equal to True
                    Then - Actions
                        Set TempPoint = (Position of (Picked destructible))
                        Item - Create Destructible's Soul at TempPoint
                        Custom script:   call RemoveLocation(udg_TempPoint)
                        Destructible - Remove (Picked destructible) [COLOR="Green"]//We remove the dest. so it can't have more than 1 item created on it[/COLOR]
                    Else - Actions

Other possible item creations:

Code:

Creating Items 4
    Events
        Time - RandomItemTimer expires
    Conditions
    Actions
        For each (Integer A) from 1 to 2, do (Actions)
            Loop - Actions
                Wait 2.00 seconds
                Set RandomPoint = (Random point in (Playable map area))
                Item - Create Orb of Frost at RandomPoint
                Custom script:   call RemoveLocation(udg_RandomPoint)

Creates 2 Orbs of Frost at random points on the map after a timer has expired ^
Note that you might want to specify these points inside a large region that doesn't contain places that
make the items impossible to reach.

Code:

Creating Items 5
    Events
        Time - RandomItemTimer expires
    Conditions
    Actions
        Custom script:    set bj_wantDestroyGroup = true
        Unit Group - Pick every unit in (Units in (Playable map area) matching (((Matching unit) is A Hero) Equal to True)) and do (Actions)
            Loop - Actions
                Hero - Create Orb of Frost and give it to (Picked unit)

Creates an Orb of Frost for every hero on the map and gives it to them after a timer has expired ^

-------------------------------------------------------------------------------

2. Removing Items

What could this function be used for?
-Removing items so units can't acquire them unless they do some actions to make it so they can
-Removing specific items

We need to start here, using the following trigger to make it so a unit can NOT acquire an item (can be specific),
unless they are a certain level and they are a certain type of hero (melee or ranged in this case):

Code:

Removing Items 1
    Events
        Unit - A unit Acquires an item
    Conditions
        (Item-type of (Item being manipulated)) Equal to Orb of Frost
    Actions
        If (All Conditions are True) then do (Then Actions) else do (Else Actions)
            If - Conditions
                ((Triggering unit) is A melee attacker) Equal to True
            Then - Actions
                Hero - Drop (Item being manipulated) from (Triggering unit)
                Game - Display to (All players matching ((Owner of (Triggering unit)) Equal to (Owner of (Triggering unit)))) for 5.00 seconds the text: Only ranged heros c...
            Else - Actions
                If (All Conditions are True) then do (Then Actions) else do (Else Actions)
                    If - Conditions
                        (Level of (Triggering unit)) Greater than or Equal to 6 and ((Triggering unit) is A ranged attacker) Equal to True
                    Then - Actions
                        [COLOR="Green"]//If the level and type of the trig unit is of the conds above, we don't do anything to them, as they are of satisfaction[/COLOR]
                    Else - Actions
                        Hero - Drop (Item being manipulated) from (Triggering unit)
                        Game - Display to (All players matching ((Owner of (Triggering unit)) Equal to (Owner of (Triggering unit)))) for 5.00 seconds the text: You are not a high ...

The above trigger is fired when a hero acquired an Orb of Frost.
If the hero is a:
-Ranged attacker
and
-Level of 6 or greater,

We don't remove the item from them.

Else if the hero is a:
-Melee attacker
or
-Level of less then 6,

We remove the item from them, as they don't meet the conditions of the trigger.

For our next trigger, we are going to make it so that an item is removed from the game
(this is just a simple version of the previous trigger):

Code:

Removing Items 2
    Events
        Unit - A unit Acquires an item
    Conditions
        (Item-type of (Item being manipulated)) Equal to Orb of Frost
    Actions
        Item - Remove (Item being manipulated)

Not much point to the above trigger, but it gives you an idea none the less ^

Other possible item removal triggers:

This one is quite handy if a group of players is going to face a boss and they are moved to a region and
are not allowed to use any items aganist it for some reason (ie, to make the situation harder).
Note that this trigger would only really be useful if the game ends after the boss dies, as the heroes would not get their items back:

Code:

Removing Items 3
    Events
        Unit - A unit enters Region <gen>
    Conditions
        ((Triggering unit) is A Hero) Equal to True
    Actions
        For each (Integer A) from 1 to 6, do (Actions)
            Loop - Actions
                Item - Remove (Item carried by (Triggering unit) in slot (Integer A))

-------------------------------------------------------------------------------

3. Hiding/Showing Items

What could this function be used for?
-Hiding keys for gates and then unhiding them after a unit enters a region

Let's use the "Map initialization" event to start off, then we are going to use the hide item function multiple times to hide all 3 of some random gate keys. After each key is created, we need to store that created item into a variable array, so we can reference it for later use, if need be.

Code:

Hiding or Showing Items 1
    Events
        Map initialization
    Conditions
    Actions
        Item - Create Gate Key at A
        Set LastCreatedItem[1] = (Last created item)
        Item - Create Gate Key at B
        Set LastCreatedItem[2] = (Last created item)
        Item - Create Gate Key at C
        Set LastCreatedItem[3] = (Last created item)

And now let's unhide each key after a unit enters A, B, or C:

Code:

Unhide Keys
    Events
        Unit - A unit enters A <gen>
        Unit - A unit enters B <gen>
        Unit - A unit enters C <gen>
    Conditions
        ((Triggering unit) is A Hero) Equal to True
    Actions
        If (All Conditions are True) then do (Then Actions) else do (Else Actions)
            If - Conditions
                (A <gen> contains (Triggering unit)) Equal to True [COLOR="Green"]//If the trig unit is in region A, LCI[1] will be shown[/COLOR]
            Then - Actions
                Item - Show LastCreatedItem[1]
            Else - Actions
        If (All Conditions are True) then do (Then Actions) else do (Else Actions)
            If - Conditions
                (B <gen> contains (Triggering unit)) Equal to True [COLOR="Green"]//If the trig unit is in region B, LCI[2] will be shown[/COLOR]
            Then - Actions
                Item - Show LastCreatedItem[2]
            Else - Actions
        If (All Conditions are True) then do (Then Actions) else do (Else Actions)
            If - Conditions
                (C <gen> contains (Triggering unit)) Equal to True [COLOR="Green"]//If the trig unit is in region C, LCI[3] will be shown[/COLOR]
            Then - Actions
                Item - Show LastCreatedItem[3]
            Else - Actions

-------------------------------------------------------------------------------

4. Moving Items

What could this function be used for?
-Moving an item to specific points (obviously). I have whipped up a few triggers for this function to show people what things it is capable of.

In this first trigger, I came up with an idea of the item "moving" around continuously
in a region just to make it harder to acquire by a unit (quite harsh):

Code:

Moving Items 1
    Events
        Time - Every 1.00 seconds of game time
    Conditions
    Actions
        Set TempPoint = (Random point in Region <gen>)
        Item - Move Orb of Frost 0003 <gen> to TempPoint
        Custom script:    call RemoveLocation(udg_TempPoint)

This next trigger will move the Orb of Frost from its current location offset by 10, towards an angle equal to its current hit points.
(quite creative IMO, but also extremely lame):

Code:

Moving Items 2
    Events
        Time - Every 1.00 seconds of game time
    Conditions
    Actions
        Set TempPoint[1] = (Position of Orb of Frost 0003 <gen>)
        Set TempPoint[2] = TempPoint[1] offset by 10.00 towards (Current life of Orb of Frost 0003 <gen>) degrees
        Item - Move Orb of Frost 0003 <gen> to TempPoint[2]
        Custom script:    call RemoveLocation(udg_TempPoint[1])
        Custom script:    call RemoveLocation(udg_TempPoint[2])

-------------------------------------------------------------------------------

5. Setting the Life of Items

Fact: the default life value for any item is 75

What could this function be used for?
-An idea would be to have a number of seconds to reach an item that opens the last gate so they can complete the game.
If the item dies, everyone loses (or something devastating should take place).

The following trigger will set the life of the Orb of Frost, to its current life - 1.
In other words, or, should I say, in other numbers, its life would end up looking like the following over 3 seconds:
74
73
72
...

Remember that if the item 'dies', we defeat all players:

Code:

Setting the Life of Items 1
    Events
        Time - Every 1.00 seconds of game time
    Conditions
    Actions
        Item - Set life of Orb of Frost 0003 <gen> to ((Current life of Orb of Frost 0003 <gen>) - 1.00)
        If (All Conditions are True) then do (Then Actions) else do (Else Actions)
            If - Conditions
                (Current life of (Orb of Frost 0003 <gen>)) Equal to 0.00
            Then - Actions
                For each (Integer A) from 1 to 12, do (Actions)
                    Loop - Actions
                        Game - Defeat (Player((Integer A))) with the message: Defeat!
            Else - Actions

-------------------------------------------------------------------------------

6. Setting the Charges Remaining of Items

Fact: Using a value of 0 for charges of an item will give the item unlimited charges, regardless if it was set through triggers,
or the Object Editor. Cooldown and mana are still used however.

What could this function be used for?
-Combining Charges of items into one inventory slot

The following trigger "combines" the charges of 2 items together to save inventory slots.
(very useful):

JASS:

function Combine_Items_Conditions takes nothing returns boolean
    return GetItemCharges(GetManipulatedItem()) &gt; 0 
endfunction

function Combine_Items_Actions takes nothing returns nothing
    local item NEWITEM = GetManipulatedItem()
    local unit OURUNIT = GetManipulatingUnit()
    local integer MAXIMUM = 15  //The max no. of charges allowed
    local integer ITEMCOUNT = 0
    local integer ITEMLOOP = 0
    local integer CHARGES = 0
    
    loop
        exitwhen ITEMLOOP &gt; 6
        if GetItemTypeId(NEWITEM) == GetItemTypeId(UnitItemInSlot(OURUNIT, ITEMLOOP)) then
            if GetItemCharges(UnitItemInSlot(OURUNIT, ITEMLOOP)) + GetItemCharges(NEWITEM) &lt;= MAXIMUM then
                if not (UnitItemInSlot(OURUNIT, ITEMLOOP) == NEWITEM) then                
                    set CHARGES = GetItemCharges(UnitItemInSlot(OURUNIT, ITEMLOOP)) + GetItemCharges(NEWITEM)
                    call SetItemCharges(UnitItemInSlot(OURUNIT, ITEMLOOP), CHARGES)
                    call RemoveItem(NEWITEM)
                    set ITEMLOOP = 7
                endif
            endif
        endif
        if (ITEMLOOP &lt; 7) then
            set ITEMLOOP = ITEMLOOP + 1
        endif
    endloop

    set NEWITEM = null
    set OURUNIT = null
endfunction

function InitTrig_Combine_Items takes nothing returns nothing
    set gg_trg_Combine_Items = CreateTrigger(  )
    call TriggerRegisterAnyUnitEventBJ( gg_trg_Combine_Items, EVENT_PLAYER_UNIT_PICKUP_ITEM )
    call TriggerAddCondition( gg_trg_Combine_Items, Condition( function Combine_Items_Conditions ) )
    call TriggerAddAction( gg_trg_Combine_Items, function Combine_Items_Actions )
endfunction

To implement this trigger into your map, simply create a new trigger called "Combine Items",
then go to Edit > Convert to custom script > hit ok > delete everything > copy + paste the above trigger into your's.

Credits go to SD_Ryoko for the original trigger.

-------------------------------------------------------------------------------

7. Making Items invulnerable/vulnerable

Fact: Items are not damaged by non-triggered spells AT ALL, regardless if the ability can target items.

What could this function be used for?
-Making items invulnerable or vulnerable, of course! I havn't been too creative here, so you'd have to decide what you'd use it for.

How to make an item invulnerable (for novices):

Code:

Making Items Invulnerable
    Events
        Map initialization
    Conditions
    Actions
        Item - Make Orb of Frost 0003 <gen> Invulnerable

Makes the Orb of Frost invulnerable ^

-------------------------------------------------------------------------------

8. Making Items pawnable/unpawnable

Fact: A pawnable item can be sold to item vendors, whilst an unpawnable one cannot.

What could this function be used for?
-To make an extremely rare/powerfull item unpawnable

Pawnable/unpawnable triggers:

Code:

Making Items pawnable or unpawnable 1
    Events
        Unit - A unit Acquires an item
    Conditions
        (Item-type of (Item being manipulated)) Equal to Orb of Frost
    Actions
        Item - Make Orb of Frost 0003 <gen> Unpawnable

Makes the Orb of Frost unpawnable; it can't be sold to item vendors ^

Code:

Making Items pawnable or unpawnable 2
    Events
        Unit - A unit Acquires an item
    Conditions
        (Item-type of (Item being manipulated)) Equal to Orb of Frost
    Actions
        Item - Make Orb of Frost 0003 <gen> Pawnable

Makes the Orb of Frost pawnable; it can be sold to item vendors ^

-------------------------------------------------------------------------------

9. Making Items droppable/undroppable

What could this function be used for?
-Every played DotA? Well, that game has an item called 'Aghanims Scepter'. This item permanantly upgrades the ultimate ability of the holder.
The item is not droppable, for obvious reasons, one of which is because it would be too pesky changing the hero's ability around
every time the item was manipulated.

Here is a suitable trigger for that item trigger function idea:

Code:

Making Items droppable or undroppable 1
    Events
        Unit - A unit Acquires an item
    Conditions
        (((Triggering unit) is A Hero) Equal to True) and ((Item-type of (Item being manipulated)) Equal to Aghanim's Scepter)
    Actions
        If (All Conditions are True) then do (Then Actions) else do (Else Actions)
            If - Conditions
                ((Unit-type of (Triggering unit)) Equal to Mountain King) and ((Level of Avatar for (Triggering unit)) Greater than 0)
            Then - Actions
                Unit - Remove Avatar from (Triggering unit)
                Unit - Add Avatar (Upgraded) to (Triggering unit)
            Else - Actions
        If (All Conditions are True) then do (Then Actions) else do (Else Actions)
            If - Conditions
                ((Unit-type of (Triggering unit)) Equal to Archmage) and ((Level of Mass Teleport for (Triggering unit)) Greater than 0)
            Then - Actions
                Unit - Remove Mass Teleport from (Triggering unit)
                Unit - Add Mass Teleport (Upgraded) to (Triggering unit)
            Else - Actions
        If (All Conditions are True) then do (Then Actions) else do (Else Actions)
            If - Conditions
                ((Unit-type of (Triggering unit)) Equal to Blood Mage) and ((Level of Phoenix for (Triggering unit)) Greater than 0)
            Then - Actions
                Unit - Remove Phoenix from (Triggering unit)
                Unit - Add Phoenix (Upgraded) to (Triggering unit)
            Else - Actions

The above trigger basically checks what type of hero/unit is manipulating the upgrader item,
and if that specific hero's ultimate is learned.

And, if that ultimate was learned, it was removed, and the upgraded ultimate was added to the hero.

-------------------------------------------------------------------------------

10. Making Items Drop/Stay with heroes upon death

What could this function be used for?
-Like in DotA, an ultra item like the Divine Rapier that gives you +250 damage is so powerfull, that it drops upon death because otherwise your hero could go on an unstoppable rampage.

I have made a trigger for this function below:

Code:

Making Items Drop from heroes upon death
    Events
        Unit - A unit Acquires an item
    Conditions
        (Item-type of (Item being manipulated)) Equal to Divine Rapier
    Actions
        Item - Make (Item being manipulated) Drop from Heroes upon death

This can also be done via Object Editor.

-------------------------------------------------------------------------------

11. Changing the ownership of Items

What could this function be used for?
-This function doesn't do much. It will usually only change the colour of the item.

<If anyone discovers something new for this function, please tell me via PM>

-------------------------------------------------------------------------------

12. Setting the custom value of Items

Fact: Custom values are used only in triggers and can be used to store any integer value.

What could this function be used for?
-To store an integer value of course!

A simple trigger showing you how to store a custom value to an item:

Code:

Setting the Custom Value of an Item 1
    Events
        Unit - A unit Acquires an item
    Conditions
        ((Triggering unit) is A Hero) Equal to True and (Item-type of (Item being manipulated)) Equal to (Item-type of Orb of Frost <gen>)
    Actions
        Item - Set the custom value of (Item being manipulated) to 1

I havn't been very creative here, but I'm sure you can be!

-------------------------------------------------------------------------------

13. Picking every Item & doing multiple actions

What could this function be used for?
-Tiny to Gigantic amounts of things.
We can use this function to include all of the stuff you have read about above and all of the functions of an item in a trigger (note that this function does not pick any item(s) in a hero('s) item slot - only items that are on the ground. However, items can be added to a hero's item slot using this function)

Example overview trigger using this function:

Code:

Picking Every Item in a Region and doing multiple actions 1
    Events
        Unit - A unit enters Region <gen>
    Conditions
    Actions
        Item - Pick every item in (Playable map area) and do (Actions)
            Loop - Actions
                Set PickedItem = (Picked item)
                -------- What we could do with this picked item: --------
                -------- [COLOR="Green"]create[/COLOR] an item at the position of it --------
                -------- [COLOR="Green"]remove[/COLOR] the picked item --------
                -------- [COLOR="Green"]hide/show[/COLOR] the picked item --------
                -------- [COLOR="Green"]move[/COLOR] the picked item --------
                -------- [COLOR="Green"]set the life[/COLOR] of the picked item --------
                -------- [COLOR="Green"]set the charges remaining[/COLOR] of the picked item --------
                -------- [COLOR="Green"]set the custom value[/COLOR] of the picked item --------
                -------- [COLOR="Green"]change the ownership[/COLOR] of the picked item --------
                -------- [COLOR="Green"]give[/COLOR] the picked item to a hero --------
                -------- make the picked item [COLOR="Green"]invulnerable/vulnerable[/COLOR]  --------
                -------- make the picked item [COLOR="Green"]pawnable/unpawnable[/COLOR]  --------
                -------- make the picked item [COLOR="Green"]droppable/undroppable[/COLOR]  --------
                -------- make the picked item [COLOR="Green"]drop from heroes upon death[/COLOR]  --------

-------------------------------------------------------------------------------

14. Making an Item Recipe

What could this function be used for?
-To look like it combines a certain number of items into 1 powerfull one, with "upgraded" abilities from the original items

Item recipe trigger:

Code:

Item Recipe 1
    Events
        Unit - A unit Acquires an item

Wow.. Nice work, your work has been neatly spread out, very neat very neat. +rep

Tinki3 · Oct 1, 2006

Thanks for the comment

Edit/bump: modified tut a bit.

ragingspeedhorn · Oct 4, 2006

All that reading, no pictures. Still pretty good though but I didn't read it to the end.

Tinki3 · Oct 4, 2006

>All that reading, no pictures. Still pretty good though but I didn't read it to the end.

Thanks for saying that There was no pictures, I will put some in asap

NiKaNoRoU_GR · Oct 4, 2006

good job

You might be given a reward

ragingspeedhorn · Oct 4, 2006

Good that you'll add the images, +rep, nice tutorial, keep up the good work

Wiseman_2 · Oct 4, 2006

I didn't read much, mainly just the item recipes, but It solved all the problems I had. +rep

Andrewgosu · Oct 4, 2006

Thumbs up.

WastedSavior · Oct 4, 2006

Code:

Stats- Use Automatically When Acquired If False: item abilities in DotA like Linkens Sphere's spell negation will not be used when needed

If True - Unit will use item instantly, like tomes/runes/glyphs
If False - Item will be placed in inventory until owner uses it

my two cents, very good tutorial though

Tinki3 · Oct 4, 2006

If True - Unit will use item instantly, like tomes/runes/glyphs
If False - Item will be placed in inventory until owner uses it

my two cents, very good tutorial though

Thanks for the correction (I will see if that's actually true or not but I think it is

testing now)

Edit: Well, it seems that it doesn't matter whether tomes have that Stat as true OR false. It only needs to be true for all other items with castable abilities like frost nova, shockwave etc. I will add this discovery into the tut to correct it

Chocobo · Oct 29, 2006

Art- Button Position (X) Items do not need these
Art- Button Position (Y) " " "

Wrong. They are used in Item Shops for their exact location.

Art- Selection Size- Editor: Not needed

Wrong. It is the selection scale that appears in World Editor to select the item. Setting it to 0.00 make it harder to be selected in WE.

Combat- Armor Type The armour type of the item(only used when the item is on the ground)

Wrong. It is the Combat Sound played. If I remember, you have Ethereal, Flesh, Wood... each of those Armor Types play differant sounds depending of attacker's Attack Sound Type.

Stats- Dropped When Carrier Dies If False: the item will not drop when the carrier dies

Does not work with normal units.

Stats- Ignore Cooldown If False: after a castable ability of that item is used, the ability will need to cooldown as hero abilities do

Ignore Cooldown if False runs the cooldown for the ability casted if it has one.

Stats- Number Of Charges: How many times the castable abilities of the item can be used

0 for Infinite

Stats- Priority Not Important

Important for AI

Stats- Use Automatically When Acquired If False: item abilities in DotA like Linkens Sphere's spell negation will not be used when needed. (it doesn't matter whether tomes have this stat as true OR false; the hero will always be able to gain +1 str,agi,int if the tome has the tome ability for that stat increase)

Used instantly when the unit acquires the item. The Event "Unit - Generic unit acquires an item" is able to handle the acquired item.

Stats- Valid For Target Transformation Not sure, however, this option is not needed 99% of the time

Allows validity for a Target Transformation.

-Item Abilities can use mana, can have a cooldown, and can have a set amount of charges which tells you how many times you can use the item ability

Only one ability, or it won't work. For multi-abilities, use a spellbook. Auto-cast abilities DO NOT work with items.

What could this function be used for?
-Nothing. Changing the ownership of an item does nothing at all.

Wrong. Sometimes it changes the color of the item.

Clear?

WC3_map_fan · Jun 19, 2007

Hello, the tutorial was great but it has no information about when you pick an item up a special effect is created on its hand such as a sword! please add to your previouse posts when you cna gather this information

WC3_map_fan, if possible, don't quote the whole tutorial on you posts. Thank You

Söder · Jul 18, 2007

Okay really good guiding! but i can't find this condition:
"((Hero manipulating item) has an item of type Orb of Frost) Equal to True2

Can somebody please tell me which condition it is?

Ghan · Jul 18, 2007

It's a boolean.

Tinki3 · Jul 18, 2007

This tutorial needs a bit of work put into it.

I'll edit it when I have the time, and upload a brand-new demo map.

For now, please keep your sanity people.

darkRae · Aug 3, 2007

I have a question peoples, or a problem to be exact.

I created an item in my map. That item has 3 passive abilities and 1 active ability. I set the cooldown of the ability to 25 sec. Then I changed the Cooldown Group to that ability.
Then in the game, when I used the item, it went into a cooldown. But it doesn't spin (the cooldown's black color) There wasn't any black color. The item kept its icon art, but I still can't use the item due to the cooldown.

The conclusion is, the cooldown works but the art doesn't. Solutions?

Ghan · Aug 3, 2007

The active ability needs to be the first in the item's list of abilities.

Xapphire · Aug 3, 2007

Hey, you know half that stuff is in the object editor in the items stats? Just mentioning it, but the tutorial is very good, it taught me a lot about, everything

ty!

Tinki3 · Aug 3, 2007

I'm glad you thought it was good.

I need to re-write most of it when I have the time.
