What will be more productive?

Question

Unity

Hello, I am making a 3D game and now at the stage of creating a check whether the character is on the ground or not. So what will be more productive: Shooting a beam from the Persian down every frame, or checking if the collider of the Persian is in contact with the collider under the "Ground" tag?

Answer 1

For check it is better to use a separate trigger. (A ray is just iterating over objects in the scene looking for suitable ones)

Answer 2

Ray.
