1# FPS Shooter
2 
3A playbook for first-person shooters — the look/move controller, the shooting model, weapon
4feel, and combat. This is a **compositional** skill: it wires a 3D controller, input, and AI
5into a shooter. It does not re-teach 3D nodes or raycasts; it defines the shooting model and
6the feel knobs (TTK, recoil, spread) that decide whether the guns feel good.

8## When to use
9 
10- Use when building a first-person game whose core verb is **aim and shoot** — arena shooter,
11  tactical FPS, PvE shooter, boomer-shooter.
12- Use when deciding hitscan vs. projectile, tuning time-to-kill, recoil, spread, or aim feel.
13 
14**When *not* to use:** third-person/2D shooting → reuse the shooting model here but build the
15camera/controller from the relevant genre. Wave survival with towers → `tower-defense`.
16For the camera/character body itself, use `godot-3d-essentials` / `unreal-cpp-gameplay`.

18## Core loop
19 
20**Scan → acquire a target → aim and fire → confirm the kill (feedback) → reposition / reload
21/ advance.** The whole experience rests on the *aim-and-fire* micro-loop feeling crisp:
22responsive look, clear hit feedback, and a death that reads instantly.

24## Must-have systems
25 
261. **First-person controller** — move (WASD/stick) + mouse/stick look, gravity, jump/crouch.
272. **Camera** — eye-height view, configurable FOV and sensitivity, recoil kick.
283. **Shooting model** — hitscan raycast and/or projectile spawn; one impact path for feedback.
