dmakatra:
setPos and getPos work fine(ish) with triggers. The qualification is that setPos [x,y,z] will result in the trigger being placed z above sealevel. This is usually not important, unless for example you plan to create an environmental sound, or an explosion at its location.
HateR_Kint:
I suppose if you have a trigger that is not a square or a circle you might want to rotate it, say to move a detected by trigger to simulate the effect of a search light or some such. Just a thought.
