So, I want to create a 2d tile-based world. In this world, I, generally speaking, have ground/dirt, water areas, lakes, mountains, etc.... The world is created randomly. Nothing is pre-designed. What are the best practices for placing ground and water tiles? do I : place water tiles above ground tiles (layering)? or create the ground tiles, deleting some of them for the water tiles? Is there a better way? I appreciate your advice. Thank you. LB.
