What problem does it solve? Building 3D gameplay in ignifx requires wiring together physics, input, animation, and pathfinding by hand. This Skill provides the operational knowledge to add third-person and first-person character controllers, follow cameras with wall collision, Animator state machines with blend trees, and navmesh-driven agents using @ignifx/3d. ## Core Features & Use Cases - Character controllers and camera rigs: Configure ThirdPersonController, FirstPersonController, and ThirdPersonCamera with correct update-phase behavior, input actions, and pointer-lock handling. - Animation state machines: Author .animator.json documents with parameters, transitions, blend trees, and animation events driven by controller state. - Navigation and presentation: Bake NavMeshSurface navmeshes, drive NavMeshAgent companions, and add LodGroup and Billboard components. - Use Case: You are building a third-person game and need a hero that walks, jumps, and sprints with an orbit camera that avoids walls, plus an NPC companion that pathfinds to the player — this Skill gives you the exact component setup, recipes, and gotchas. ## Quick Start Ask the AI to create a third-person character with a follow camera and a baked navmesh in an ignifx project using @ignifx/3d.
