On this project i worked mostly on the AI aswell as the LD integation aswell as some physics.
The Ai is a state machine with A* pathfinding. It uses raycasting for vision and the world is buildt up in the background with a grid system.
The ld integration that i worked on was mostly with making sure level designers could put tags and objects in their level editor (unity) and make sure it correctly came into the engine.
For the physics, i mostly helped where i could with the players gameplay mechanics that used physics because i was in a good position to help them.
