Question by Rawmp · Dec 09, 2013 at 10:29 PM · javascriptyaxis

How can i set yAxis boundaries for a 2D game?

I'm making a pong-like game and i can't figure out how to set boundaries for the paddle. for example, when i press the key to move the paddle up it moves off the screen.

  • Use Colliders or Joints if you are using physics.

  • Use Mathf.Clamp if you're using your own movement logic.

  • Solve it any other way, there are many ways to solve the problem.

Example:

 // Using Mathf.Clamp to stop yAxis from going below -10 and above 10.

 // Apply movement
 yAxis += Input.GetAxis("Vertical") * Time.deltaTime;

 // Restrict to bounds
 yAxis = Mathf.Clamp(yAxis, -10, 10);
