This is a basic nonscrolling background Basic Platformer. This version uses sensing blocks to avoid if blocks. It uses both the left right, not touching ground (gravity) sensing tricks, as well as using the sensing trick to change platforms. It also has a (somewhat inefficient) pull out routine: 1. apply gravity (fall a little) 2. if touching ground, pull out until not touching. 3. sink in for a second, to see if we are close enough to the ground to jump 4. if so jump 5. pull out of the ground again. (optional) * arrow keys (in foreer loop)move left and right * turns off gravity if touching ground * detects color to change platform * jumps and falls at steady rate until touching ground Problem: going left doesn't pull you up.
