[Trigger] Why isn't this trigger working?

[MN Lahmar]

Hello, i'm trying to create a trigger that when a unit enters a region it'll get hit by the spell Entangling Roots.

• Trap1
  • Events
    • Unit - A unit enters Region 378 <gen>
  • Conditions
    • (Owner of (Triggering unit)) Equal to Player 4 (Purple)
  • Actions
    • Set TempPointTrap = (Position of (Triggering unit))
    • Unit - Create 1 Dummy (Trap) for Player 9 (Gray) at TempPointTrap facing Default building facing degrees
    • Set Trap_Dummy = (Last created unit)
    • Unit - Add Trap to Trap_Dummy
    • Unit - Order Trap_Dummy to Night Elf Keeper Of The Grove - Entangling Roots (Triggering unit)
    • Unit - Add a 1.00 second Generic expiration timer to Trap_Dummy
    • Custom script: call RemoveLocation (udg_TempPointTrap)

In this case Trap equals to Entangling Roots with 0 mana cost and 99999 range.
I don't know what the problem is! The game freezes every time this trigger gets launched.

You trigger looks fine to me. The only thing i could think of right now is that it has to do something with the spell ?

EDIT: One other thing, try this trigger with manually giving the ability in the OE to the unit please.

At the beginning of your trigger, use the action:

• Trigger - Turn off This trigger

If you don't, i think this trigger will be fired every time the dummy unit is created, because it means a unit enters region 378, which means infinite loop, hence the freeze.
You may want to turn the trigger on again after the dummy was created, if you want more units to be affected by the spell (beware of the expiration timer though, it may be problematic if several units enters that region within less than 1 second, because the variable Trap_Dummy may refer to another dummy.)

Don't know how i missed this lol. Just add a condition for the dummy unit and you're good to go.

but the dummy is owned by player 9, the trigger only fires for player 4 anyway. so i'm not sure if that's the problem. do you have any other triggers referring to that region? or a "enters entire map region" trigger for player 9?

The game freezes every time this trigger gets launched.

Please elaborate. If you mean that the Warcraft III client drops a few frames that would be because you did not preload the dummy unit and ability and are creating the dummy on top of another unit resulting in costly pathing displacement. Place the dummy somewhere on the map at map initialization to force it to preload and create it some distance away, or preferably recycle the dummy unit.

If you mean the Warcraft III client permanently stops updating the game and has to be forcefully closed that would be because of an infinite loop. Can happen with some object editor abilities that have periodic effects when the period is set to 0 (infinite occurrences per unit time).

I suspect it's because of the infinite loop, just a hunch.
Also, just a suggestion, it'll be better to create just one hidden dummy unit than to create a unit over and over again.

 

[UreDe4D]

why would it create an infinite loop? the dummy does not match the condition of the trigger as it's owned by a different player. or am i missing sth here?!

 

[Rheiko]

There might be another trigger that collides with this one. As I said, just my hunch.
