Cannot convert vector3 to collider?-CodePudding

I'm trying to make a 3D racing game on Unity and I am currently looking to program checkpoints. Right now I have hit a roadblock in which I can't convert vector3 to collider. Any advice?

private void OnTriggerEnter3D(Collider Checkpoint)
    {
        if (Checkpoint.tag == "Checkpoint")
        {
            Checkpoint = transform.position;
        }
    }

CodePudding user response：

Checkpoint is a Collider data type. Try it with Checkpoint.transform.position

CodePudding user response：

A Collider is not at all a Vector3. I invite you to read the documentation for both types to understand better what each is used for.

As mentioned in another comment, if you want to access a Collider position, you should use Collider.transform.position (so

Checkpoint.transform.position

in your case). If you want to move the Collider around, as mentioned in the documentation, you should attach a Rigidbody to it (probably a kinematic Rigidbody) and move it.
