I have this, it's more complex and 2 player. It has some bugs and still need to do the scoreboard.
If want to try use:

• 'w' and 's' for left.
• 'up' and 'down' for right.
  The comments are in spanish.

You have 2 options: limit the speed or make a system within the bar hitbox is bigger so the ball can't go through the bar. Hope it helps. El lun., 14 oct. 2019 a las 11:51, VevarN (<[email protected]>) escribió:

I tried this and it´s great, just that when the ball reaches a certain speed, it goes straight through the moveable bar. Any ideas on how to fix? — You are receiving this because you commented.
