code

Hi Ahmed,

Could you please elaborate a bit further on what you did in your project and what your problem is? At the moment, all I know is that the next scene gets loaded without a button, which does not sound like a problem to me.

yes but i dont want it do that until i lose

Ahmed_Khaled · July 7, 2020, 10:09am

Unity’s physic engine is highly optimised meaning it checks the position of a collider occasionally only. You could try to set the Collision Detection mode of the ball’s Rigidbody2D to “Continuous”. In most cases, that fixes the problem.

In our particular case, the problem is that we manipulate the transform.position via code and override the calculated values of the physics engine. It is likely that the position of the ball does not match the position of the collider anymore.

A better solution would be to disable the physics simulation for the ball while manipulating the position via code.

void Start ()
{
    paddleToBallVector = transform.position - paddle1.transform.position;
    myAudioSource = GetComponent<AudioSource>();
    myRigidBody2D = GetComponent<Rigidbody2D>();
    myRigidBody2D.simulated = false; // <-------- add this
}
 
private void LaunchOnMouseClick()
{
    if (Input.GetMouseButtonDown(0))
    {
        hasStarted = true;
        myRigidBody2D.velocity = new Vector2(xPush, yPush);
        myRigidBody2D.simulated = true; // <-------- add this
    }
}

I hope that makes sense.
