Hello, I am absolutely brand new to Processing. Brand new.
I am just playing around and Im wondering if someone can help me get the code correct so that my image rotates on key input.
/**
* Easing.
*
* Move the mouse across the screen and the symbol will follow.
* Between drawing each frame of the animation, the program
* calculates the difference between the position of the
* symbol and the cursor. If the distance is larger than
* 1 pixel, the symbol moves part of the distance (0.05) from its
* current position toward the cursor.
