Hi ,

It looks like you were following my tutorial here, correct?

If so, i’ll be happy to help out where I can. I noticed one thing for certain, you don’t want to run the line trace for the grappling hook off of your event begin play. That will allow it to run once and then it will be useless from that point on. You want to run it off of an input key such as LMB or 1. The Input binding you have should have the close functionality on release and the trace functionality on press. Fix those up and see if it works, if not let me know what it is specifically doing and I’ll see if I can figure out what is happening.
