How do you make an wall jump? for 3d games

maybe you can use empty objects similar to how the ground check works and put them on the side of the player. then whenever they jump it checks first the ground then the wall and if the wall is the only one that works change a bool to false so it can't work again until the bool is changed back when the player jumps off the ground.

So, this is a script I've created to make the WallRun. It is imperfect and incomprehensible so use this Website and follow the instructions: WallRun.com It really helps me.
