Hello, I’m making a platform game endless runner. I have a car on the platform using real physics and a rigidybody but as ilistra the image, I’m not getting the second image effect, my car is going backwards. Can anyone help me make the car ride only forward!

One way to do this would be to constrain the x value on your velocity.

void FixedUpdate(){
    float xSpeed = rigidbody2D.velocity.x;
    xSpeed = Mathf.Clamp (xSpeed, 0, Mathf.infinity);
    rigidbody2D.velocity = new Vector2 (xSpeed, rigidbody2D.velocity.y)
}

This will result in strange physics though. A better way would be to simply add sufficient force so that the car can overcome any ramps in its path.
