how to check if one object is colliding with another

THE FOLLOWING SCRIPT IS JAVA SCRIPT

//start of script

var otherObjectTag = "Object";

function OnCollisionEnter (hit : Collision)

{ ///you are colliding

Debug.Log("CollidingWithAnything");

if(hit.gameObject.tag == otherObjectTag){ //now colliding with certain object

Debug.Log("Colliding With Certain"); }

}

///end of script

DO NOT COPY THIS OR ANYTHING PAST

hope it works

you have to add a collider besides the Character Controller for this to work but that shouldnt mess anything up. just go to Component>Physics>(Id recomend capsul collider) then make sure the capsule collider is bigger then the CharacterController

 void OnCollisionEnter (Collision c) {
         if (playerObject!=null){
             
             if (c.gameObject.tag == playerObject.tag){
                 tempest = true;
             }
         }
     }
