And the gun doesnt stop firing, and idk how to fix it.BTW i am using the UE 4.8.3.

You’ve linked to a video of a project and setup that is not broken. There are lots of possibilities for what went wrong: not binding to trigger release, not linking release trigger to anything, not checking for the current firing state…

Can you provide any details about your actual implementation that demonstrate how what you are doing is different so we can track down what your problem might be?

Images of your blueprints, descriptions of your execution paths, etc?

Also, what is the actual behavior you’re experiencing? Does it behave properly until you pull the trigger, then it starts firing and never stops? Does it begin firing as soon as you start the game?

More detail and clear description will almost always give you a better answer in less time.
