Is there a "use stored ability" action?

[cleavinghammer]

I'm trying to create a "voodoo doll" spell: the doll selects a visible allied or enemy unit; after which any ability/buff cast on the doll will also be cast on the unit until one or the other dies.

However, I can't seem to find an "order dummy to use the spell that was just cast" trigger (even by storing the ability as a variable), is there a way to do that, or is the only option to put an if/then/else trigger for EVERY ability in the game?

Inside the object editor find your ability. Scroll down to the Text - Order String field.

Then issue your unit that order via triggers.

For example if the order string is "firebolt" you would do this

Unit - Order (Triggering unit) to Neutral - Firebolt (Target unit of ability being cast)

 

[cleavinghammer]

But can that work for every ability? I want to know if there's a way to automatically have the game cast the used spell, instead of having to trigger every possible spell: "if ability = firebolt, give firebolt, use firebolt on target; if ability = frost nova, give frost nova, use frost nova on target, if ability =..."

Sorry, I'm a bit confused by your question.

Untitled Trigger 001 Events Unit - A unit Starts the effect of an ability Conditions Actions Set Unit = (Triggering Unit) Set Target = (Target unit of (Ability being cast)) Custom script: call IssueTargetOrderById(udg_Unit, GetIssuedOrderId(), udg_Target)

You're talking about GUI, where you can't do 'Unit - Order' and set the ability as a variable?

Use this instead; it's the same line, but in JASS.

• Custom script: call IssueTargetOrderById( udg_VoodooDoll, udg_Ability, udg_Target )

It takes the ability by ID, so store the ability in a variable first, then replace udg_Ability with the variable you're using. If you variable is called VoodooAbility then in JASS, it would be udg_VoodooAbility

You also need to replace udg_VoodooDoll with the variable that holds your voodoo unit.

And finally, replace udg_Target with the variable that holds your voodoo unit's target.

Edit: grr, wasn't fast enough.

Thanks to the both of you.

I tried it, and while the dummy unit shows up and has the correct ability, she doesn't cast it.

Gotta post the trig.

Where are you setting dollTarget ?

Edit: Do everything in one trigger not multiple. I think dollTarget may be getting overwritten.

I tried it like this, but it's still doing everything but using the spell.

Never use do nothing.
use starts effect of ability and combine the two trigger you have in post number 8.
The way you do it in post 10 is pointless.

Where is the target getting the buff "target" from?

Check your dummy unit "cast" to make sure it has mana to cast the spell. Also, depending on how your target is selected, your spell may not be able to target the 'target unit'.

You can find out exactly why it's not casting if you try it in game, then select your 'cast' dummy and manually try to cast the spell yourself. Take off Locust or anything else that may prevent you from selecting your dummy unit. It's probably because of mana or 'Target is not allowed'.

 

[cleavinghammer]

The "target" buff is based off of Faerie Fire with infinite range. First I have the doll cast it on the unit. (If no one has the target buff I tried to set the spell to be cast on the caster instead of Do nothing, but that causes something like 18 dummies to appear around the caster every time he casts.)

            • Unit - Add dollabil to dollcast
            • Custom script: call IssueTargetOrderById( udg_dollcast, udg_dollabil, udg_dolltarget )

When I try to cast the spell manually (Purge in most cases), it works perfectly (dummy is based off the sorceress without Locust, abilities or upgrades, has full mana, has the ability and is able to cast it).

That IF statement is being run for every unit in your map (Pick every unit in X and) so when it checks to see if they have the buff, and they don't, it's going to run that Else statement for every unit that doesn't have the buff.

You need another variable to check if there was a target for the voodoo doll. Set it to false at the start of the spell, and set it to true, if the doll found a target. Then at the end of the spell, you can check if it found a target, and if not, THEN set the target as the caster.

Keep in mind that the way you currently have it "Unit - Create 1 cast for (Owner of (Triggering unit))", your dummy caster will be owned by the same player as the caster, so it may not be able to cast all spells on the caster (friend isn't allowed as a target). This is actually true for almost any spell that you would attempt to cast on an enemy. The owner of the dummy must be something like Neutral, but then neutral would take credit for killing the caster if it were to die.

=================

Back to your original problem. The trigger looks fine, it should be casting at the target. If it wasn't casting, then there may not be a target (no one has the target buff). Try adding a debug message where the dummy caster is attempting to cast the spell, like "Game - Message to all players 'attempting to cast'" so you can see if it's actually running.
