Running, Jumping, etc.

Running, Jumping, etc.
This is another topic that I will not use in my game but I will like to create a game like this. With the codes I had to type I noticed how flexible the code is. It was funny to have the character jumping too high. Then when I change the code it gradually changes. I see why there is so much control on the jumping in games. If it was not, for the control in the game, it would not be as fun and will not teach us anything.
