I don’t usually really script in this style. Kinda new for me but I wanted to try it out so I started off with a simple shield. For now all you have to do is click “Q” to activate or deactivate. But the only way I could think to do it is to weld it to the torso so you can’t jump for some reason. Feedback would be great! 
If you want to play the game here you go,
I couldn’t think of a game name so this is magic, lol
