USPSA Shooter — Unity 3D

A small first-person 3D shooter inspired by a USPSA (United States Practical Shooting Association) match. You run a two-stage course of fire against a buzzer, scored by hit factor (points ÷ time). Stage 2 adds an armed ranchero bad guy who shoots back — use cover and put him down to clear it.

The entire match (arena, lights, player, targets, the ranchero, the HUD) is generated procedurally from C# at runtime using Unity primitives. There are no imported models, textures, materials, or prefabs to break — open the scene and press Play.

Requirements

• Unity 6 LTS (6000.0.x) recommended. Any Unity 2021.3+ will also open it (Unity Hub will offer to upgrade-open). Built-in Render Pipeline.

How to open & run

1. Open Unity Hub → Add → Add project from disk and select this folder (USPSA-Shooter).
2. Open the project. Unity imports and compiles the scripts (first open takes a minute).
3. Open the scene Assets/Scenes/Match.unity if it isn't already loaded. (It contains a single GameManager object that builds everything else.)
4. Press Play.

Controls

Input	Action
W A S D	Move
Mouse	Look
Left mouse	Fire
R	Reload
Shift	Sprint
Space	Jump
F	Make Ready / start the buzzer (when prompted)
Space	Advance after a stage / restart match
R	Re-shoot a stage after you go down
Esc	Free the mouse cursor

Match flow

1. Make Ready — press F. After a random delay the buzzer goes (GO!) and the clock starts.
2. On the clock — engage every target. Scoring follows USPSA conventions:
   • Paper targets need two hits ("double tap") to be neutralized. Hits are zoned by height: A = 5, C = 3, D = 1.
   • Steel poppers fall on a single hit (5 points).
3. Stage 1 — "El Presidente Bay": freestyle paper + steel, no return fire.
4. Stage 2 — "The Ranchero Strikes Back": paper targets plus the ranchero. He fires dodgeable bursts at you from behind a barricade — break line of sight behind cover. He takes ~3 solid hits. The stage clears only when all paper is neutralized and the ranchero is down (+15 bonus).
5. Each stage reports time, points, and hit factor; the match summary shows a combined hit factor.

You regenerate health a few seconds after the last time you were hit. If your health reaches zero on Stage 2, you go down and can re-shoot the stage with R.

Tuning

Most feel knobs are public fields you can tweak in code or, after pressing Play, on the live objects in the Hierarchy:

• WeaponController: damage, fireRate, magSize, spread, recoilKick
• RancheroAI: burstSize, fireInterval, aimError, projectileDamage, strafeRange
• PlayerController: walkSpeed, mouseSensitivity, jumpHeight
• HealthSystem: maxHealth, regenRate, regenDelay

Note for this machine (WDAC)

Running in the Unity Editor (Play mode) is fine. However, a built .exe of this game will be blocked under WDAC enforcement until it's whitelisted by Publisher (Unity-built players are typically unsigned, so you'd sign it first, then approve the signer). That's only relevant if you do File → Build — for development just use Play mode.
