THE TECHNICALITIES - HOW THINGS WORK? (See code snippets and Unity Inspector Images in Presentation)
The Revolver and The Bullet Projectile:
The revolver makes use of the “Blaster Script,” which includes the projectile prefab, shooting point, and XRGrabInteractable. Shooting is managed by BeginShootWithDelay and ShootWithDelay Coroutine, controlling firing rate and reloads. The “Projectile script” controls bullet behavior, moving it forward and handling collisions with enemies. Upon the bullet/projectile hitting an “enemy”, a Blood particle effect is shown, and the bullet is destroyed after a delay. The “Bullet script” simplifies collision detection, focusing on destroying the bullet when it hits enemies.
The Zombie Walk and Die Animation:
The animator controls the movement of the “Enemy,” or zombie, as well as the death sequences. The "Speed" parameter in the Animator manages their walking animation, while the "Die" trigger initiates their death animation upon collision with player projectiles. The HumanoidEnemyDeath script handles the destruction process, disabling the zombie's Collider and NavMeshAgent before destroying the GameObject.
Zombie Spawning, Count, and Player Health:
Zombie spawning is triggered by the player shooting a button gameobject with the bullet projectile. This causes a specified number of zombies to spawn around the scene. The GameManager script tracks the zombie count (Specified from the Button Activation Script), updating UI elements displaying the remaining zombies and player health. As zombies are destroyed (by collision with player projectiles) or the player's health decreases (upon collision with zombies), the GameManager loads win or lose scenes. The HumanHealthTracker script handles player health, reducing health upon collision with zombies and notifying the GameManager of health updates. UI Changes are reflected in the corresponding Text Mesh Pro Elements assigned in the inspector.
AI Enemies - NavMesh:
AI navigation of the zombies relies on them being given the component of NavMesh agents, which allows them to follow and move along a surface that has the NavMesh component. Using the “Navigation Script,” the zombies are set to detect the location of the gameobject (XR Origin Capsule) with the “player” tag, and move towards that object. NavMesh obstacles exist on objects within each of the levels/scenes, and provide “non-walkable” surfaces for the zombies to avoid.
