MFPC – Modular First Person Controller

MFPC – Modular First Person Controller

MFPC is a clean, extensible first person character controller designed for developers who want full control — not a rigid framework.

It provides a production-ready foundation for FPS, immersive sims, walking simulators, and narrative experiences — with a strong focus on clean architecture and modular design.

Controller-first, not demo-first.

Demo Inputs (customizable in Unity editor):

1. PC: 
   1. movement: wasd or arrows
   2. camera rotation: mouse
   3. aim: mouse right (hold)
   4. sprint: shift (for this demo it's toggle mode - hold mode can be selected in Unity editor)
   5. crouch: ctrl (for this demo it's toggle mode - hold mode can be selected in Unity editor)
   6. jump: space
2. Gamepad:
   1. movement: left stick
      
   2. camera rotation: right stick
   3. aim: LT
   4. sprint: left stick press
   5. crouch: B (Xbox controller), A (Nintendo controller)
   6. jump: A (Xbox controller), B (Nintendo controller)

Movement & Player State

• Walk, Sprint, Crouch, Jump, Aim, Lean
• Hold or Toggle modes (configurable)
• Forward-only sprint restriction
• Collision-safe auto-uncrouch
• Optional auto-unsprint when stopping movement (toggle mode)
• Optional advanced slope handling
• Physics interactions with environment.

Movement is predictable, tweakable, and free from hidden behavior.

Input Systems

• Legacy Input System controller
• New Input System controller
• Mouse + keyboard support
• Gamepad support (tested with multiple controllers)
• Sensitivity parity between input systems
• Frame-rate independent mouse smoothing (New Input System)

Swap input systems without rewriting gameplay logic.

Camera System (Cinemachine-based)

MFPC is built around Cinemachine, not custom camera math.

• Virtual Camera setup for: idle, walk, sprint, crouch, aim
• FOV kick on sprint (via Virtual Camera swap)
• Headbob via Cinemachine Noise (no custom scripts)
• Custom camera blends for smooth transitions
• Separate aim camera variants
• Clean integration with camera stacks

Optional module included:

• Disable headbob/noise globally (no need to edit cameras manually)

You control the camera behavior visually — no black-box logic.

Animation & Events (Optional Modules)

MFPC does not require an Animator — but integrates seamlessly with one.

AnimatorBridge:

• Syncs Animator parameters from controller state and velocity
• Supports movement speed, grounded, crouch, sprint, aim
• Includes jump/fall detection and vertical velocity
• Works with both input system controllers
• Optional auto-detection and LateUpdate syncing

Perfect for driving blend trees and layered animation setups without modifying the controller.

EventObserver:

• UnityEvent-based state transitions — Jump (leave ground), Land, Sprint / Crouch / Aim / Move / Lean
• Inspector-friendly — no custom scripting required
• Ideal for audio, VFX, UI, or gameplay hooks

These modules keep MFPC lightweight while enabling full production integration.

Optional Stamina System

• Sprint drain and regeneration
• Jump stamina cost
• Exhaustion and recovery behavior
• Fully optional — no UI or HUD required

Includes a demo stamina UI example, which can be completely removed without affecting MFPC.

Audio System

• Surface-based footsteps and landing sounds
• Terrain and object support
• Water surface handling
• Audio pooling (no runtime instantiation spikes)
• Easy to extend with ScriptableObjects

No hardcoded layers. No forced setup.

Architecture & Design Philosophy

MFPC is intentionally not an all-in-one solution.

• No forced Animator Controller
• No stamina system assumptions
• No UI or HUD dependencies
• No required layers or tags
• No multiplayer logic baked in
• Zero GC allocations in Update

Instead, MFPC gives you:

• Clean state logic (by exposing variables)
• Clear extension points
• Optional systems via future modules

Build exactly what you need — nothing more.
