Hi everybody.

Im currently working on a system of mine. The buff engine.
The problem is that its just not MUI.
I'll give you the code. The system contains 3 example triggers and the loop.
It seems to be something with the loop.
When casting a buff on several units, they will have infinity duration.
When casting two buffs different buffs on units, all of them will have the latest casted buff in inifity time. I hope you can help me.

[Update]
- Allright, i have found out that my system isnt indexing right, but i dont know how to fix it. Could anyone help me?
- The problem is that it in the loop, is replacing the old values with the new ones.

Well I already see a problem here:
  • Set Buff_Position[Buff_Index] = (Position of (Picked unit))
you use Buff_Index without setting it anywhere (therefore it will always affect only the last added buff). You should not loop through Buff_Group, but through Buff_Indexes from 1 to 50.
Click to expand...

Im not sure if you mean the following.

I have to get rid of the unit group, and just do

  • For each integer (Integer) from 1 to (Buff_IntegerMax)
    • Set Buff_Position[Buff_Index] = (Position of (Picked unit))
    • [...]
If thats what you mean, then i'll go recoding my system ;)
If not, then please describe it a little bit more. Im pretty new to indexing ;)

Not exactly. Here, you use (Picked unit) without Pick Group. The unit you will be referring in this loop is Buff_Caster[Integer A].

If I understand it correctly, you want to keep track of some buffs. That means you need to evaluate each buff every second, not each unit. If one unit had more buffs, it wouldn't work.

Also, you can access unit through buff ID (you saved unit in Buff_Caster), but you can't get buff ID from unit. So for that reason it is easier to loop through buff ID's, rather than units.

So basically what you do each second is that you loop through all buffs there are, substract 1 from their duration and check if they expired. (Also evaluate any effects the buff has)
  • Loop
    • Events
      • Time - every 1 second
  • Actions
    • For (Integer A) from 1 to BuffIDMax
      • If (multiple)
        • Conditions
          • Buff_Caster[Integer A] not equals to No Unit
        • Then
          • Set Buff_duration[Integer A] = Buff_duration[Integer A] - 1
          • If (multiple)
            • Conditions
              • Buff_duration[Integer A] less than or equal to 0
            • Actions
              • Set Buff_caster[Integer A] = no unit
            • Else
              • //--------buff effects
