Chance for two effects

[bumbaclo]

I'm trying to make a passive spell that has a % chance to slow and deal extra damage. It seems simple enough but I can only find a spell that can do one or the other. I'm not even sure how I could put this into trigger form. Is there a spell that can allow 2 different effects in the same chance?

[roaaaarrrr]

Could you just use the frost orb item ability? That adds damage and has a % chance to slow...

 

[Bogrim]

HeX.16, can you please stop posting unnecessary long triggers that barely has anything to do with what the original poster has requested? It's very confusing for new posters to be presented to such triggers, which they'd have to heavily modify to gain what they requested.

Bumbaclo, I don't know what spell you are using, but you can achieve this by casting an additional spell on the target by chance. With triggers you can create just about anything in the game, including a second "invisible" unit that can do various things to supplement your original spell. We call these units dummy units.

To create a standard dummy unit, go make a copy of the Locust unit in the object editor, and do the following things:

1. Change the unit's art model to ".mdl" (this will make the unit invisible).
2. Turn off the unit's shadow model.
3. Turn off the unit's attack.
4. Give the unit as large a mana amount as you can type.

You can further adjust the dummy unit, but this will suit your basic needs.

Now to create a trigger, we can use the Frost Nova ability to cause both additional damage and slow the target. By default, Frost Nova causes area of effect damage, but if you set the area of effect to 0, only the main target will be hit. You can also edit how much damage and for how long you want the slow to last this way.

• Events
  • Unit - A unit Starts the effect of an ability

The event states that this trigger should fire when a unit uses an ability. This is central for how the trigger will respond to the ability you are triggering.

• Conditions
  • (Ability being cast) Equal to Your Spell
  • (Random integer number between 1 and 10) Equal to 1

In the first condition, replace "Your Spell" with the spell you are using for this ability. This condition is essential to make sure the trigger only occurs with your specific spell and not any other spell.

In the second condition, we use the game's random seed to create effect of a chance. By default, I set it to 10%. If you want the chance to increase per level, you can use the spell's level as a mathematic equation:

• (Random integer number between 1 and 10) Less than or equal to (Level of Your Spell for (Triggering unit))

This will give the spell a 10/20/30% chance of proccing the bonus effect.

For the actions, you first need to create some variables (access the variable window by pressing CTRL + B). Variables are what triggers use when refering to data or objects in the game. Because we need to create a dummy unit to cast our additional spell, we need to create a location for the unit to appear at. Create a point variable and name it "Temp_Point".

Your first action should be "Set Variable" using the variable you just created:

• Actions
  • Set Temp_Point = (Position of (Target unit of ability being cast))

Next we create the unit to cast the spell with at the location we just specified with a variable. There are many unit actions to choose from, but a simple "Create unit" will do.

• Unit - Create 1 Dummy Unit for (Owner of (Triggering unit)) at Temp_Point facing Default building facing degrees

Your Dummy Unit will most likely be listed under Custom Undead units if you made a copy of Locust like I said earlier.

You can just add the ability the unit should be casting beforehand in the object editor, but it's easier to just add through an action and then you can use the same dummy unit for any other triggers as well.

• Unit - Add Frost Nova (Dummy Unit) to (Last created unit)

Remember that the ability should not be a hero ability, otherwise the unit cannot use the ability.

If you want the bonus effect to scale with the levels of your main ability, add levels to the Frost Nova ability and use this action:

• Unit - Set level of Frost Nova (Dummy) for (Last created unit) to (Level of Your Spell for (Triggering unit))

The dummy unit is in place and has the ability required for the bonus effect, now just make the unit use the ability with the "Unit - Issue Order Targeting A Unit" action:

• Unit - Order (Last created unit) to Undead Lich - Frost Nova (Target unit of ability being cast)

Finally we have to get rid of the objects we used to create this effect, otherwise they will just remain and take up useless memory in the game (making it slower). We do this with these actions:

• Unit - Add a 1.00 second Generic expiration timer to (Last created unit)
  • Custom Script: call RemoveLocation( udg_Temp_Point )

And there you have it. The final trigger should look like this:

• Melee Initialization
  • Events
    • Unit - A unit Starts the effect of an ability
  • Conditions
    • (Ability being cast) Equal to Your Spell
    • (Random integer number between 1 and 10) Less than or equal to (Level of Your Spell for (Triggering unit))
  • Actions
    • Set Temp_Point = (Position of (Target unit of ability being cast))
    • Unit - Create 1 Dummy Unit for (Owner of (Triggering unit)) at Temp_Point facing Default building facing degrees
    • Unit - Add Frost Nova (Dummy) to (Last created unit)
    • Unit - Set level of Frost Nova (Dummy) for (Last created unit) to (Level of Your Spell for (Triggering unit))
    • Unit - Order (Last created unit) to Undead Lich - Frost Nova (Target unit of ability being cast)
    • Unit - Add a 1.00 second Generic expiration timer to (Last created unit)
    • Custom script: call RemoveLocation( udg_Temp_Point )

If you want the special effect to look different, just edit the Frost Nova to whichever effects you prefer (if none, just delete the ability's effects).

 

[bumbaclo]

Thanks for the detailed reply Bogrim, it makes sense, but is not quite what I originally wanted. I forgot to mention my spell is to be a passive spell, and the two effects should proc on the same chance. The spell I originally tried to base it off was the orb of slow ability, which gives a chance to slow; however I can't seem to be able to add extra damage to it as well (only when the slow occurs).

 

[Bogrim]

That makes quite a difference in the amount of explaining required.

Just make Orb of Slow's spell cast Frost Nova instead of Slow. ;-)

 

[roaaaarrrr]

Hmm, what about bash or drunken brawler. Don't have editor in front of me now, but I think bash is a chance to stun and deal extra damage. Just change the stun buff to a frost nova buff instead.

It doesn't work like that. Buffs only manipulate the art attachments and tooltip displayed by the effect, but you can't change the actual effect with buffs.

 

[roaaaarrrr]

yeah, I meant the effect... I wasnt sure if there was an option to change that in bash... I know in several spells you can change the spell effect.
