Paddle Tenis game having issues

[ElipsGames (ElipsOnYT)]

You can write your topic however you want, but you need to answer these questions:

1. What do you want to achieve? Keep it simple and clear!
   the ball should bounce againsed the wall every time
2. What is the issue? Include enough details if possible!
   it phazes through the wall
3. What solutions have you thought of so far?
   ive tried thickening and doubling up the walls

Ok so im working on a Paddle Tenis game (Im a scripter btw) and the ball from the ball launcher phazes through the back wall if you wana check it out first hand here BarTest - Roblox

it doesent always do it but it does sometimes…

Thanks for any help
