VRTD: VR Tower Defense

The game runs a living ecosystem of faction-based AI. Three NPC types—farmers, attackers, and zombies—each with distinct motivations and targeting logic—operate independently. Farmers defend the castle gate and seek out enemies to destroy; attackers and zombies target the gate directly or swarm chickens and other NPCs. All characters are driven by a shared base locomotion system that handles pathfinding, animation blending, and ragdoll physics on death.

You control the battlefield through hand-tracked VR controllers. Dual-trigger bullet fire spawns projectiles from each hand at controller velocity; bombs are thrown and explode on impact with radius-based damage. The ripple post-processor shader adds a visceral distortion effect on environmental impact. VR-specific mechanics include thumbstick locomotion with controller-relative movement (not camera-relative), intuitive aiming with physics raycast collision detection, and haptic feedback on weapon firing.

A destructible health system tracks damage on all characters and structures. NPCs dynamically spawn at configurable intervals, adapt their speed and aggression when targeting enemies versus wandering, and leave physics-enabled ragdoll corpses that settle into the environment. The castle gate is the focal point—a destructible structure that both farmers and attackers prioritize, creating emergent tower-defense scenarios without explicit player towers.
