[Solved] Enter Region only working for Player 1?

[sethmachine]

Hi,

Why is this trigger only firing for player 1? AFAIK, there's no parameter for a player argument for an Enter Region event. This trigger works perfectly for Player 1, but it won't do jack for any other player.

    static method enterMain takes nothing returns boolean
        local player p = GetTriggerPlayer()
        local integer pid = GetPlayerId(p)
		call DisplayTimedTextToPlayer(players[pid], 0, 0, 10, "Entered a region?")
    endmethod

    method setup takes nothing returns nothing
        local trigger t = CreateTrigger()
        call TriggerAddCondition(t, Condition(function CreepRegion.enterMain))
        call TriggerRegisterEnterRegion(t, this.r, null)
        set t = null
    endmethod

Are you sure the players[] array is initialized correctly?

That's not the problem (I just checked myself, but players[] is properly initialized and works in all other instances.). And here, I'll change it to "p."

The problem is the trigger isn't firing for anyone except Player 1. This doesn't make sense to me, since you cannot bind EnterRegionEvents to specific players without a filter. And I'm not using any filter
here.

Edit: I tried changing it to TriggerRegisterEnterRegionSimple but it didn't change squat.

    static method enterMain takes nothing returns boolean
        local player p = GetTriggerPlayer()
        local integer pid = GetPlayerId(p)
	call DisplayTimedTextToPlayer(p, 0, 0, 10, "Entered a region?")
    endmethod

    method setup takes nothing returns nothing
        local trigger t = CreateTrigger()
        call TriggerAddCondition(t, Condition(function CreepRegion.enterMain))
        call TriggerRegisterEnterRegion(t, this.r, null)
        set t = null
    endmethod

Can you post what condition "CreepRegion.enterMain" is? That's the only thing I can see that would do it

 

[sethmachine]

This is CreepRegion.enterMain...

    static method enterMain takes nothing returns boolean
        local player p = GetTriggerPlayer()
        local integer pid = GetPlayerId(p)
    call DisplayTimedTextToPlayer(p, 0, 0, 10, "Entered a region?")
    endmethod

Does using "p" still input a message to Player 1 (Red)? If not, then I would test to see if GetTriggerPlayer() works for that event. You might want to try GetOwningPlayer(GetTriggerUnit()).

Otherwise, you should probably post the rest of the struct and the test script.

Genius purge. That was the problem. GetTriggerPlayer() returns null for these kind of events.

The reason why it worked for player 1 was because the integer pid defaults to 0 for null players?

Yep. For future reference, GetTriggerPlayer usually works with things like TriggerRegisterPlayerEvent or TriggerRegisterPlayerUnitEvent, but for other events, I would use something else, such as GetOwningPlayer.
