the question is why does when i press up, the next rotation call would be error and if i continue press up the error will accumulate.. the goal is to create the circle to be controlled by key arrow. can anyone show me my mistakes?
i have this code and if I run the code, the result is static picture.. but according to my understanding it should move from right to left.. any silly mistakes that someone can find??
i`m new to processing and i`m trying some test to create a moving box with a path beside the box.. the box will move according to the mouse position and a line will follow the path that the mouse took. the moving box is done, but the line i created is also refreshed with the box.. is there any help with this?
i`m starting to use Processing for the 1st time, and wondering is there possible to yields 2 windows in 1 program? if it is possible how to do it then?
