- ## TODO - ## TODO
- Modify entity loading logic to use the new parsing code by parsing all entity properties into a hashmap first then recreating entity from that - Implment writing to file through the new Parser and Parser_Object
- Change Config to read/write using new Parser logic
- Store Materials in new format supported by parser
- Add model description file which has the same syntax supported by parser and modify old blender exporter to conform to new standards
- Implement sound/listener loading from scene file - Implement sound/listener loading from scene file
- Finish loading scene from file - Finish loading scene from file
- Update makefiles to be able to compile the code in it's current state - Update makefiles to be able to compile the code in it's current state
