i think what you mean is turn on - off ?then disable the 3rd person view when -1st is typed and disable 1st person view when -3rd is typed.
Im not really sure what u want from a question like that ?
Yes,Ima use trigger to turn off/on for camera view,here how I'm doing. Event..unit type 1st as an exact match/action..lock camera target to triggering player.dats for 1st..n for 3rd Is also the Same...it work but when I'm on the 3rd person view,n I when I type 1st,it doesn't change back to 1st person...
so that statement is wrong after all :\you can't merge them, they can collide if merged.
