Oh!! Thanks men .. okay ill try it. +rep

 

[aschenzkimutech]

I try your trigger, its okay but something wrong .. i want that for example when a hero pick boots of speed and orb of froze. The hero can afford only one boots of speed while orb of froze he can afford two orb of froze. BTW, thanks .. need help please !!

Sorry but this is not correct.

• ((Triggering unit) has an item of type (Item-type of (Item being manipulated))) Equal to True

-> This will always evaluate to true, since the event for Acquires an Item fires after pickup. So, the hero always has an item of the type of item he just got.

• Set TempPoint = (Position of (Triggering unit))
• Unit - Order (Triggering unit) to drop (Item being manipulated) at TempPoint
• Custom script: call RemoveLocation(udg_TempPoint) //udg_ plus whatever the name of your point variable is in the editor, this cleans leaks

-> This is not a good place to use orders, instead use

• Hero - Drop (Item being manipulated) from (Triggering unit)

--------------------
If you want the hero to only be able to use one of each item-type, the approach is basically:
- Loop through every inventory slot (For Integer A from 1 to 6)
- Compare item-type of item in slot to item-type of manipulated
- If it's the same, and the items themselves are not the same, drop the manipulated one

I can write it for you, but I'd probably do it in JASS. Really though, I'd encourage you to try to figure this out yourself. It's not a hard trigger and will help you understand loops.

EdgeOfChaos thanks for your help but how could i read the jass script i didn't know about jass. it is possible to convert it to GUI so that i can easily understand. Once again thank you for helping me +rep

Nope, unfortunately there's no GUI of removing memory leaks.
You don't have to memorize it right now. Just copy and paste it for the time being. You'll eventually memorize it automatically in no time. That's what I did.
Just make a GUI Custom script, type in: call RemoveLocation(udg_TempPoint)

BTW, The TempPoint is an example name of Point variable. You just add "udg_" before the actual name if you're using it in jass.


So if the name of the Point is "aschenzkimutech", you type:
call RemoveLocation(udg_aschenzkimutech)

• Set aschenzkimutech = (Position of (Triggering unit))
• Custom script: call RemoveLocation(udg_aschenzkimutech)

This is in vJASS; make empty trigger then convert it into custom script via Edit menu in Trigger Editor, then paste this:
