Using Triggers to remove things

[Springheel]

Is there any restriction for how many triggers can target a specific entity?

 

I'd like to remove some AI from the map once a character reaches a certain point, but there are two possible routes a player could go. If I put triggers at both of them, the first trigger will remove the AI...but will the second trigger cause a fuss if the player hits it later because there's nothing left to remove?

You can always make two brushes and turn them in to one trigger entity.

Oh, didn't know that; thanks Jesps.

There should be no fuss. If the target isn't present, nothing happens.

 

I've used a variation of this in the past.

 

Two triggers ( A & B ) in different places both target a trigger_once ( C ). C targets the entity I'm trying to do something to. If the player passes through A, this triggers C, which does something to the entity. Since C is a 'once', it's removed (or disabled, don't know specifically). If the player later passes through B, B tries to trigger C, but C is no longer around (or disabled), and nothing happens.

 

Same result if the player goes through B first.
