SimplePhysics Class

Delta Engine Documentation

Groups various simple "physics" effects that can be applied to Entities. These do neither use actual physics functionality nor provide interaction to objects that do, but can prove to be a more efficient solution if just aiming for plain movement of sprites. View code on GitHub
