Checking if something is near object.

Hey all,

I have an enemy gameobject and i'd like for it to sidestep but first i have to check to see if theres a wall in the way or anything.

I have 2 ideas on how to do this and would like to know which is more optimized?

If i just put a collider next to him and check the collider for collision w/ the wall would that be ok? The other option i have is raycasting a line out of him maybe 3ft or so and checking to see that ray got any hits w/ the wall.

Which method is better? My game is for android/gearVR so i'd like to get input on these 2 methods. or.. if theres any better way?

 

do you mean "instantiate a new game object with a collider attached"?

raycast/spherecast sounds like it's going to win hands down.
