Fix: Godot 4 Physics Body Collision Misses Fast-Moving Projectile

Sniper round at 1000m/s passes through a 5cm wall. Hit detection misses.

Enable CCD

bullet.continuous_cd = true

Sweep-tests against the world per step. Catches thin walls.

Or use a raycast

For very fast projectiles, raycast each tick along the path. Physics bullets are heavy; raycasts are cheap.

Thicken walls

If geometry permits, walls >= bullet's per-tick distance. Avoids the bug class.

“Discrete physics misses fast motion. CCD or raycast bridges.”

For projectiles, raycast-based motion is the universal answer. RigidBody motion is for tumbling objects.
