Mario Game

Lately I have been working on a basic 2D game. In my game I've been using the jumping  and falling I learned. You control Mario from the popular Nintendo game. So far I've gotten Mario to jump but to also come down. When I was learning how to jump at first it wasn't really jumping. It was just going up in the world and falling when I released the space bar. I used to be able to just hold the space bar and I could pretty much my my actor fly but I changed that. I wrote the code so that the actor can only jump when he is on the ground and not in the air.
