In episode 3 of our Scratch RPG tutorial we improve our tile engine to be lag free, fast and efficient even for huge legend of Zelda style maps. To do this we implement a tile viewport, and also optimise the painting to only paint important tiles, and use a background painter to cover the rest of the grass areas. This Scratch tutorial is filled with helpful tips that will help you create the best Scratch Games ever!
