## What it does

This skill lays out the loop of finding a target, aiming, firing, confirming a kill, then repositioning or reloading. It covers a first-person controller, camera, hitscan or projectile fire, weapons and ammo, health, damage, enemy AI, and hit feedback.

It includes pseudocode for hitscan shots, projectiles, and time-to-kill calculations based on health, damage per shot, and fire rate. Damage, fire rate and health are meant to be tuned together. Hitmarkers, impact effects and kill confirms are part of the combat feedback.

The skill composes a shooter from related controller, input, physics, AI and camera skills. Mouse look should use raw mouse delta rather than multiplying it by `dt`, because sensitivity would then vary with FPS. That is a reason to check input handling before tuning weapons.

## Install

### Claude Code (native platform)

1. **Skills CLI (Vercel)**
```bash
npx skills add gamedev-skills/awesome-gamedev-agent-skills --skill fps-shooter -a claude-code
```

2. **Manually: put the files in place**
- File: `~/.claude/skills/fps-shooter/SKILL.md` — Copy the whole skill folder; for one project use .claude/skills/fps-shooter/

### Codex

1. **Skills CLI (Vercel)**
```bash
npx skills add gamedev-skills/awesome-gamedev-agent-skills --skill fps-shooter -a codex
```

2. **Manually: put the files in place**
- File: `.agents/skills/fps-shooter/SKILL.md` — For all projects use ~/.agents/skills/

### Cursor

1. **Skills CLI (Vercel)**
```bash
npx skills add gamedev-skills/awesome-gamedev-agent-skills --skill fps-shooter -a cursor
```

2. **Manually: put the files in place**
- File: `.cursor/skills/fps-shooter/SKILL.md` — Cursor also reads .agents/skills/ and .claude/skills/

### GitHub Copilot

1. **GitHub CLI**
```bash
gh skill install gamedev-skills/awesome-gamedev-agent-skills fps-shooter
```

2. **Manually: put the files in place**
- File: `.github/skills/fps-shooter/SKILL.md`

### Gemini CLI

1. **Skills CLI (Vercel)**
```bash
npx skills add gamedev-skills/awesome-gamedev-agent-skills --skill fps-shooter -a gemini-cli
```

2. **Platform CLI**
```bash
gemini skills install https://github.com/gamedev-skills/awesome-gamedev-agent-skills --path skills/genres/fps-shooter
```

### Windsurf (Devin Desktop)

**Manually: put the files in place**
- File: `.devin/skills/fps-shooter/SKILL.md` — The legacy .windsurf/skills/ path still works

### OpenCode

**Skills CLI (Vercel)**
```bash
npx skills add gamedev-skills/awesome-gamedev-agent-skills --skill fps-shooter -a opencode
```

### Claude.ai

**Claude.ai**
- Zip the folder and upload it in Settings → Capabilities → Skills

Where a file is given instead of a command, copy the files from the source to that path: https://github.com/gamedev-skills/awesome-gamedev-agent-skills/tree/HEAD/skills/genres/fps-shooter/SKILL.md

## When to use it
- build a first-person movement and look controller
- choose between hitscan and projectile shooting
- calculate time-to-kill from damage and fire rate
- tune weapon recoil and spread
- add hit feedback and enemy combat states

## Example prompts
- “Design a first-person shooter with movement, weapons, health and enemy AI.”
- “Compare hitscan and projectile shooting for this weapon.”
- “Tune recoil, spread and time-to-kill for the current combat loop.”

# 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.

## Design knobs

| Knob | Effect | Sane default |
|------|--------|--------------|
| Time-to-kill (TTK) | lethality, forgiveness | Tune dmg × fire-rate × HP together (refs). |
| Hitscan vs projectile | aim skill type | Hitscan = flick; projectile = lead/dodge. |
| Damage falloff | range limiting | Full to ~20 m, floor by ~60 m. |
| Headshot multiplier | skill reward | ~1.5–2.0×. |
| Recoil pattern | learnable kick | Fixed pattern > pure random. |
| Spread (bloom) | suppress laser-accuracy | First shot accurate; grows while firing. |
```
