UnitAddAbility does not recognize integer variable

[Ardenian]

To reduce the functions in my map, I merged some triggers and wrote a general
one.
I have a problem with adding abilities saved in a variable.

// In map conf:

set udg_ChaosAbility[1] = 'h000' 
// udg_ChaosAbility is an integer variable with array

// in trigger

call UnitAddAbility( udg_TempUnit, udg_ChaosAbility[1])

However, it does not work, the unit is not transformed.
( ChaosAbility is a Chaos-based ability)

Interesting though, as this works:

local integer abilityid = udg_ChaosAbility[1] 
// when the variable is an ability variable with array

call UnitAddAbility( udg_TempUnit, abilityid)

Could you please enlighten me ?

You need to post more of the script which does work and does not work. Possibly some other error is causing a thread crash before the call to the UnitAddAbility native.

In this case I know 100% sure the lines I posted are causing this.

It seems making udg_Chaos_Ability[array] an ability variable and simply placing it in
UnitAddAbility works.
Though I don't understand why setting an integer variable to the ability only works when
setting a local integer to the integer variable and the placing the local integer instead of
the integer variable in UnitAddAbility

I can assure you it works with integer variables because both are integer variables. Look at the output JASS map script.

There must be something more to this that is not in scope of what you posted.

native UnitAddAbility takes unit whichUnit,integer abilityId returns boolean

Hm, strange, very strange. I said with believe that the lines are sufficient as the problem
solves itself when setting a local integer to the global integer variable and using the local in
the UnitAddAbility().
There isn't really code I can post without pages of explanations why I do this and that.
However, here is a small example:

local unit u = CreateUnit( Player(0), 'hfoo', x, y, facing)
        call UnitAddAbility( u, 'Aloc')
        call UnitRemoveAbility( u, 'Aloc')
        call UnitAddAbility( u, udg_DG_Chaos_Ability[whichability])
        set u = null

// array whichability is an integer the function takes

Are you modifying udg_ChaosAbility anywhere else? Try moving this line:
set udg_ChaosAbility[1] = 'h000'

Immediately before UnitAddAbility. I'm guessing that you are calling another event (through your code) that will modify udg_ChaosAbility, so it ends up adding the wrong ability.

This post explains what I'm referring to. If you launch any events inbetween the assignment of udg_ChaosAbility to 'h001' and UnitAddAbility, and that event ends up changing udg_ChaosAbility within its actions, then it can cause a conflict. That would explain why the local variable assignment works when the global variable doesn't.

 

[Ardenian]

I set udg_ChaosAbility[1] in the map initialization, after that it is not set to anything else.
Hm, however, I would not exclude the possibility that the issue you desribe occurs,
might be a wrong line somewhere.

Alright, thank you PurgeandFire and Dr Super Good!

Well integer array certainly works with UnitAddAbility so I'm guessing it has something to do with your map.
