WASD for basic movement Click and hold to shoot the grapple hook. You will automatically be pulled towards it once it hits a wall or ceiling, and you will keep your momentum once you let go. Just a project testing a grapple hook I made. The code is messy, unoptimized, and laggy right now, but it seems to work fine. I don't know what I'll do with this, I just made it on a whim. (The next game I release probably won't be related to this). Might be good for a platformer or Attack on Titan game maybe? Feel free to use it if you want.
The platformer engine is based on @griffpatch's Youtube tutorial. Everything else is by me.
