Godot 4 3D Platformer Lesson #22: Enemy (Part 3)! : Cliff-Detection! Auto-Turn-Around @BornCG

Uploaded March 2025 | Updated September 2026, 2 weeks ago

In this lesson we'll add to our game level enemies the ability to detect & turn around at a cliff when an enemy approaches one! We'll enable this per-enemy, so that we can decide which enemies will fall off cliffs (& stairs), and which ones won't, using an @export-ed variable.
