Dynamic Enemy Spawner & Swarm AI (Prefabs, Triggers, & Bug Fixes)

Dynamic Enemy Spawner & Swarm AI (Prefabs, Triggers, & Bug Fixes)

This 24-minute session is essential: we replace the old, static "enemies on rails" with a dynamic Enemy Spawner System and Swarm AI.

We cover C# setup for wave timing, using Trigger Areas to launch enemy prefabs, and the complex logic of moving enemies toward the player while implementing terrain avoidance. Crucially, you'll see the real-world debugging of enemies running through walls and the problem solving using Prefab Variants.
