So I am using unity and wondering if I have an agent going to move to a position say Agent A moves to position B in x seconds guaranteed (avoids all physics or things that could disrupt the path). When agent A gets to his destination I want to trigger some effect C.
I was thinking you could do this same sequence with both colliders that are trigger and coroutines but wouldn't doing it with coroutines be more efficient and if so by how much ?
Physics is usually the most complex part in a comparison. however, triggers aren't really physics, they're just collision detection which is quite fast for primary shapes. On the otherhand, coroutine doesn't need half the calculation triggers need. In fact, the only calculation a coroutine needs is some TIME behind the scenes, so, coroutines are much faster than collision detection, however, depening on your case, you might want to use the trigger way because you are literally looking for a collision detection. It's not that heavy even on mobiles.
