Game 6 Highlights

// Run This Function in END STEP event
/*
 INSTRUCTIONS: 
 This function requires passing in arguments playerSpeed (not hspeed or speed) 
 and a gravity value.
 
 You should also make an optional argument maxFall with a value of 15
 
 In addition, you need to have two variables in the create event
 of your object:
 
     jumpSpeed = 0
     canJump = true
	 
optional:  Jumping variable (needed in create if you are going to have
		   a jumping animation (controlled in step).
