Overview
In this episode, you'll implement two fundamental shooting mechanics: hitscan (instant raycast hits) and projectile (physics-based bullets). By the end, your weapon will fire either instant-hit shots or visible projectiles, both with visual feedback.
This episode builds directly on Episode 7 (youtu.be/QrfskQNs3aM) state machine. We're adding actual shooting logic to replace the print statement.
What You'll Learn:
Raycast-based hitscan shooting
Physics-based projectile system
Toggling between shooting modes
Basic impact visualization
Prerequisites:
Completed Episode 7 (Weapon State Machine)
Understanding of Godot's raycast system
Basic 3D math (vectors, directions)
