THE ANSWER TO MY QUESTION HAS BEEN DETERMINED

Question/Problem:

I am creating a game that requires walls. (The way I have my gravity set up, the player will not fall off of the edge of the game ground. Therefore, I must block the players in.) I’m not sure how I would create the walls (I am using a cube as the wall.) without implementing a Rigidbody.

All you need is a collider and your character a rigid body and a collider. If your walls are complex in shape you can use a Mesh Collider to make sure your characters don’t do the David Copperfield on you
