Advanced shooter meta-systems

Load for lag compensation, explosion queries, and server rewind — pairs with godot-adapt-single-to-multiplayer.

Client prediction + server authority

# CLIENT — juice immediately
func fire_client() -> void:
    play_effects_immediate()
    local_tracer_only()
    rpc_id(1, "server_validate_shot", camera.global_transform)

# SERVER — damage only here
@rpc("any_peer")
func server_validate_shot(xform: Transform3D) -> void:
    var hit := perform_server_hitscan(xform)
    if hit and is_valid_shot(hit):
        rpc("confirm_hit", hit.victim_id, hit.damage)

• Predict tracers locally; never sync every bullet.
• Server wins on mismatch — show "no reg" feedback.
• Use ENet/UDP, not TCP, for fire events.

Lag compensation (rewind)

Ring-buffer transforms; on shot, rewind targets to client timestamp, raycast, restore — lag_compensator.gd.

CAUTION: Rewind, raycast, and restore in one physics frame — leaving bodies displaced breaks other server sim.

Shape explosion query

Sphere intersect_shape without Area3D spam — shooter_patterns.gd pattern 3; also see explosion helper in patterns file.

Hit zones

Use collider/shape names or bones for head/chest multipliers — avoid == on floats; use is_equal_approx() for damage math.

Monte Carlo balance
