Can't change color of the material, Unity-CodePudding

First of all , i'm following an Unity C# tutorial on youtube and I'm stuggling to see why my code is not working, basically I'm using a script with "void OnCollisionEnter(Collision collision) to just change gameObject material color to red , but is not showing the change nor showing an error, my object (a sphere) has a rigidbody and the material I'm using on it has a standar shader and it's rendering mode it's opaque and I made it blue

the code I'm using on it's script:

void OnCollisionEnter(Collision collision)
{
    gameObject.GetComponent<Renderer>().material.color = Color.red;
 }

and it does nothing, tried changing the shader , the color on the code and I still have no idea why isn't changing on Unity

CodePudding user response：

Are you sure the method is being called? OnCollisionEnter is triggered when this collider/rigidbody has started contact with another rigidbody/collider.

Check that there is a collider/rigidbody on the object that the sphere collides with and on the sphere itself

Also, try using Debug.Log() to make sure that the code is triggered.

I checked your line in the Start() method, it works. The problem is something else

CodePudding user response：

First make sure it runs within the function. Use Debug.Log () for this purpose. Use this if the function performs correctly.

private void OnCollisionEnter(Collision collision)
{
    Debug.Log("On Collision Enter: "  collision.gameObject.name);
    
    GetComponent<MeshRenderer>().material.color = Color.red;
}
