FPS Shooter

A playbook for first-person shooters, the look/move controller, the shooting model, weapon feel, and combat. This is a compositional skill: it wires a 3D controller, input, and AI into a shooter. It does not re-teach 3D nodes or raycasts; it defines the shooting model and the feel knobs (TTK, recoil, spread) that decide whether the guns feel good.

When to use

• Use when building a first-person game whose core verb is aim and shoot, arena shooter, tactical FPS, PvE shooter, boomer-shooter.
• Use when deciding hitscan vs. projectile, tuning time-to-kill, recoil, spread, or aim feel.

When not to use: third-person/2D shooting → reuse the shooting model here but build the camera/controller from the relevant genre. Wave survival with towers → tower-defense. For the camera/character body itself, use godot-3d-essentials / unreal-cpp-gameplay.

Core loop

Scan → acquire a target → aim and fire → confirm the kill (feedback) → reposition / reload / advance. The whole experience rests on the aim-and-fire micro-loop feeling crisp: responsive look, clear hit feedback, and a death that reads instantly.

Must-have systems

1. First-person controller, move (WASD/stick) + mouse/stick look, gravity, jump/crouch.
2. Camera, eye-height view, configurable FOV and sensitivity, recoil kick.
3. Shooting model, hitscan raycast and/or projectile spawn; one impact path for feedback.
4. Weapons + ammo, damage, fire rate, magazine, reload, switching.
5. Health + damage, HP, hit/headshot multipliers, death; player and enemy share the model.
6. Enemy AI, perceive → alert → attack → search; cover and reaction delays (game-ai).
7. Feedback, hitmarkers, impact decals/particles, hit sounds, screen shake, kill confirms.
8. Objectives, what you do besides shoot: clear, capture, survive, escort.
