I have a game that creates randomized tiles spawn from the top of the screen. They move down one pixel every 0.01 second to create a scrolling effect. At the speed of 1 pixel, the generator creates perfectly spaced cells. However, when i increase the speed to 3 pixels instead of 1. The generator creates unaligned blocks with thin spaces in between the cells and eventually ruin the the perfectly spaced grid. I attatched the mfa file along with some screen shots. Please comment on how to solve this problem!
