Help, im using unity 2020.3.15f2, OnCollisionEnter is not working.

I have 2 gameObjects, both with not trigger SphereColliders and not Kinematic RigidBodies.

My RigidBodies doesn´t have gravity on, but they have constants (don´t move on z, and don´t rotate on x or y)

Im shure they collide because both gameobjects interact colliding, but when i call the script that contains the OnCollisionEnter (that just call a Debug.Log("Collision")) i don´t see anything on console.

void OnCollisionEnter(Collision col){
  Debug.Log("Collision"); //i don´t see anything on console
}

This is my SphereCollider and RigidBody setup for both GameObjects:

And the script is on the parent of those GameObjects, like this:

This is the Scene Hierarcy

And this is the "Element" Hierarchy (note: i edit it to mantain the names of my gameobjects in secret its my boss desition)

As you can see here the "Element" its the one who have the script with the OnCollisionEnter

CodePudding user response：

I Solve by thinking: How my scene is setted?, I see that the gameObjects that contain the Collider and the RigidBody, are child of the gameObject with the OnCollisionEnter script.

Aparently, OnCollisionEnter only works with the gameObject itself, if the script is attached to a parent or to a child of the gameObject, it´ll not work.

So with that, i just need to make a Collision Detection Script on the gameObjects with the Colliders, and entangle it with the parent´s script to do... the thinks the gameObject should do when collide.

Thanks all for your feedback and help, special thanks for @derHugo and @Ruzhim who are the people who help me to detect that problem.

Solution: make shure the script with the OnCollisionEnter is on the gameObject that have the Collider and the RigidBody, not the parent, not the child.
