Ok so I have a couple of questions here. I made a script for one of my activators.

scn ScienceLabTrigger01Scriptref trapfloat timerBegin OnTriggerActor PlayerActivate ScienceLabDoor03ScienceLabDoor03.Lock 100set trap to 1endBegin GameModeif trap== 1 && timer > 20set timer to timer - GetSecondsPassedelseif trap==1 && timer < 20MessageBox "Tadaa"endifend

When testing, I run into the activator, and who would have guessed it, nothing happens D:.
My other question is, the activator is a 2d purple wall. Is there a way I can make the activator invisible, without screwing up the size of it?
If anyone could help either or both of these questions, it would be greatly appreciated.
Thanks

The activator needs to be a trigger zone.

Use the trigger zone meshes instead. That will solve your second problem too.
