is it possible to make a script that repeats something until a brick collides with something?

I want to make a laser script that fires a laser and keeps growing until it eventually hits another part. Can someone tell me if this is possible?

Yes, it is possible. Unfortunately, I cannot provide you with the script because this site is an helping site and not a request site.

But, here's a liitle help. Raycast Documentation : https://developer.roblox.com/en-us/articles/Raycasting

And then you can use a while loop and inside the loop, you can check whether the part touched something and if yes, you can break the loop.

Lemme know if it helps!
