The Player has a Multi State assigned to the Jump field in the PlayerInputBrain so that when the Jump button is pressed, the character will automatically activate the correct type of jump action depending on their circumstances.

None of the enemies have any jump states because the AI logic required to properly utilise jumping to traverse an environment would be very complex and is beyond the scope of the Platformer Game Kit.

Jump A basic fixed-height jump from the ground.
Hold Jump Hold the jump button to jump higher.
Wall Jump Jump off walls as if they were the ground.
Air Jump Jump a limited number of times in the air before needing to touch the ground.
