# Iso Engine

Smol little game engine since I have no idea what I'm doing
# Notice:
Since this uses the newer cpp modules, you need to make sure your compiler + build system + IDE supports this. You can

# Ideas for this/future engine
Also just an outline for stuff
- Custom Logger
- CMake / Premake / XMake
- Event System
- Window Handler (support multiple windows)
- Layer system
- Math helpers
- Static/Dynamic linking
- Export or Build (export game as game file, or build your own exe directly)
- Shader System
- Entity Component System?
- Profiling
- Scripting? (lua?) + while-running / preprocessed scripts
- Tools (Sprite Sheet Tools, etc)
- Asset Manager / Pipeline (choose between .pak or individual files)
- Physics
- Collision Detection
