Someone asked if I could share this and I have no plans for it, so I figured why not.
The project is done in 4.10 and the files are zipped up with 7zip. Here’s a link to it: LightsaberProject.zip - Google Drive
It’s messy and partially commented, but it shouldn’t be too hard to figure out.
I think the only controls are these, if you can’t find them in the character BP: Left mouse + ctrl/alt/shift for attacks. Spacebar and hold for jump. 1 for turning on the blade. 2 for changing colour. 9 for options, 0 for show fps.
