How do I create a visual laser?

Hello all,

I am trying to make a laser beam, and I'm pretty close, but I'm running into a few issues I can't solve.

My laser will go through walls if it hits the wall at a certain point

Here is a video of the issue: youtu.be/vmMFqZsxIyI

It's worth mentioning that when the laser goes through a wall, it flickers, but it flickers so fast that it doesn't appear in the recording.

Here is my code for the laser:

Any help in appreciated!

Thanks for the help, with your advice I was able to get it working!

For anyone who comes across this in the future, here is the working code!

Thanks again for the help!
