Help: Trackables

[jnZ]

Ok here is what i am trying to do: i want to create a "movementsystem" (more or less) that allows moving 1 hero (for each player) without having him selected.
I asked and searched arround and noticed that the only way to do this is via trackables.

So i looked at some trackable turtorials but because i understand a sh*t of jass in rly understood nothing >.<

I would be rly glad (and +rep) if anyone here could edit the trigger below (from 1 of the turtorials) so that the above mentioned features work. (in my map up to 10 players will be able to play to it would be awesome if this could be MPI but every player only got 1 hero so no need for MUI (makes no sense here anyway ^^)

> when i tried to edit the Trackable trigger i noticed that its quiet easy and a nice feature to let the hero face wherever the mouse currently is.

When i tried to edit this trigger i got critical errors everytime so i thought it would be the best to ask here arround for help

    local real x = GetTrackableX(GetTriggeringTrackable())
    local real y = GetTrackableY(GetTriggeringTrackable())
    local location loc = Location(x,y)
    call SetUnitFacingToFaceLocTimed(udg_Hero, loc, 0.5) // I GUESS THIS IS THE FACING PART QUIET EASY TILL HERE

Which tutorials did you read?
There is a really good one over at wc3campaigns, and no offence, but if you don't understand JASS you really shouldn't try and use these. As from what I gather, not many people do!

(in my map up to 10 players will be able to play to it would be awesome if this could be MPI but every player only got 1 hero so no need for MUI (makes no sense here anyway ^^)

I don't think you can make trackables MPI because you can't actually get triggering player from the player who moused over or selected the trackable.

 

[jnZ]

the whole trigger posted here is all i need (if you make him like 1 want he even would be shorter by some lines)

this movementsystem is essential for my map but the only thing i cant handle because it requiers jass. so you want me to stop my project because of this little piece of jass that is surely easy done by some skilled (and rep needing xD) people here?

EDIT:

>I don't think you can make trackables MPI because you can't actually get triggering player from the player who moused over or selected the trackable.
it is possible i also read this in the turtorial. by creating severeal trackables that are only accessible to certain player. so for 8 players 8 trackables at exactly the same postition

 

[AdamGriffith]

Your problem might be the fact that GetTrackableX and Y arn't actual functions... ^^

 

[quraji]

In my opinion, you have two options:

1. Learn JASS and figure it out.

2. Try to find or get someone to make a system that works for you.

The reason I say this is that Trackables are relatively complex to begin with, and adding more players and movement and all that only furthers the complexity.

As people are mentioning, there's really no functions at all for handling trackables and it all needs to be created manually.

i didnt post my edited trigger...
the trigger above works, it came with a testmap (ill attach it right now)

 

[AdamGriffith]

Did you copy the trigger out of that map only?
Because there is a ^&*( load of functions in the map header such as the GetTrackableX and Y

 

[jnZ]

yeah i know about that, i edited things like that. i am a jass noob but iam not an idiot dude

EDIT: however i would never be able to edit the trigger so it does what i want ^^ only making it work in my map wouldnt help

 

[AdamGriffith]

You should not touch the function in the map header.
That is a system called Local Handle Variables made by Kattana.
You should also not touch the trackable functions in their.
Only change the functions in triggers.

(What exactly is wrong?)

 

[jnZ]

like i said i need the trigger edited: currently its creating a explosion if a trackable is hit and some overheat stuff i dont need. i want to order the hero of the trackable clicking player to move to the postition of the trackable. thats all. and the facing stuff whenever a trackable is tracked at the start of the trigger but thats a piece of a cake.

however iam not capable of editing the trigger without causing XXX errors

did you actually read why i created this thread?

 

[AdamGriffith]

Stay online for 15 minutes.
Ill have ago for you.

 

[jnZ]

sweet, you think you can handle that? +rep for you efforts ofcourse

 

[AdamGriffith]

Blah I had it working.
Then I fucked it up.
One minute

 

[jnZ]

"nonsense" so you can post again

 

[AdamGriffith]

YAY!

Try it out and see if its what you want.
I just used a single variable.
But you can use an array if you need more than one player.
Also, if this is the case there is a function something like GetTrackablePlayer(trackable)

[Waaaaagh]

Oh wait, mine was wrong.

 

[jnZ]

yeah that awesome dude but tell me:

i removed the first function the Trackable track thing because its not needed. will this cause error. the trigger looks like this now and seems to work:

function TrackableHit takes nothing returns nothing
    local real x = GetTrackableX(GetTriggeringTrackable())
    local real y = GetTrackableY(GetTriggeringTrackable())
    call IssuePointOrder(udg_Hero, "move", x, y)
endfunction

function Trig_Init_Trackables_Actions takes nothing returns nothing
    local trigger hit = CreateTrigger()
    local trigger track = CreateTrigger()
    local real x
    local real y = GetRectMinY(gg_rct_Bomb_area) + 64
    local real maxY = GetRectMaxY(gg_rct_Bomb_area)
    local real maxX = GetRectMaxX(gg_rct_Bomb_area)
    loop
        exitwhen y > maxY - 64
        set x = GetRectMinX(gg_rct_Bomb_area) + 64
        loop
            exitwhen x > maxX - 64
            call NewTrackable("war3mapImported\\4x4Trackable.mdl", x, y, GetPlayersAll(), track, hit)
            set x = x + 128
        endloop
        set y = y + 128
    endloop
    
    call TriggerAddAction(hit, function TrackableHit)
endfunction

//===========================================================================
function InitTrig_Init_Trackables takes nothing returns nothing
    set gg_trg_Init_Trackables = CreateTrigger(  )
    call TriggerAddAction( gg_trg_Init_Trackables, function Trig_Init_Trackables_Actions )
endfunction

also can you tell me how iam able to change those gg_rct_Bomb_area to the playable map area?

 

[AdamGriffith]

I dont know.
Try it.
If you get errors, come back and tell me. I'll look into it

EDIT:
I dont see why not. They are only regions. Or you could just drag that region to fill the entire area. Dont drag it right up to the edge though. Trying to create trackables of the edge might not be such a good idea

 

[Waaaaagh]

I spy unnecessary dynamic triggers.
