Hello there!
I am making a custom beam-type weapon, but there seems to be a bit of a issue.
It activates and fires with no issues, but it doesn't keep using Mana and the sound stops after clicking and holding as well.
Here's the Item code:
And here is the Projectile code:
Any help would be appreciated, thank you!
