Thanks Jak and Dave. I’m making good progress today and I’m quite pleased. Now got 4 rows of tiles 2 diff sizes, also changed the ball from a sprite to an ellipse, didn’t like the sprite. Added scoring and Also added a little damping to try to tone down the rebounds as it’s getting really fast.
No problems atm be which is a major plus, I’m now trying to figure out how to give a slight random variation to the ball direction when it hits the bat because sometimes the ball just goes up and down like mad with no sideways movement.
Here is my code! You think it’s getting decent?
