Player Controller – I created the player movement, collecting and deposting medicaton. Carrying patients, performing surgery and moving in ambulance.
Buildings– I created that beds and machience can be construced, upgraded and that they process or produce resouces.
AI – I created three types of AI. Patients that can be pickup and move to beds. Nurses that can bring patients to beds and get resources to heal them. Truck unloader that moves boxes to the machines to process the resources.
Upgrades– I created that you can upgrade buildings and the player. The buildings can be upgraded in two ways capacity and speed. The player in the same to ways capacity and speed.
