Hi everyone ! I would like to make an enemy "Move To" target or "Find" target with Raycast2D, and when that Raycast2D of enemy collides obtructs, enemy will find another ways automatically. PLEASE HELP ! Thank you so much !

Raycast isn't a very good way to find a target. Maybe this tutorial would help get you started, or you will probably need to find a tutorial on youtube that is close to what you are looking for.

Thank you so much, bro ! Maybe I have to use an other way.

There is a new tutorial on raycasting also:

a year later
