My Part

As a stealth game, the enemy behavior was a main concern. So, my part was to handle any implementation and systems concerning those unfriendly creatures. This included creating a tool and implementation for behavior trees, navigation graph creation and traversal, animation and logic interactions, … Later in development, I took over maintenance of other implementation areas and did a full refactor to split up all logical parts to run independently (player, enemy, world, UI, …).


It is hard to develop a system when its final game design is unknown. The enemy behavior turned out to be much simpler than expected, so a simpler system as a custom behavior tree with scene-wide navigation would probably have saved quite some development time. On the other hand, using the system to make some changes in the end was quite fast. And, of course, the experience I got while developing it will be helpful. For the refactoring part: I absolutely love dependency injection when it is set up correctly. Just dragging a few objects into a scene and having them work together correctly without having to configure anything else is perfect for enjoying testing features and building new levels!
