MFPC - Modular First Person Controller

MFPC – Modular First Person Controller

MFPC is a clean, modular, production-ready first person controller for developers who want full control — not a rigid framework.

Built for FPS, immersive sims, and narrative experiences, it provides a solid movement foundation while staying completely flexible: no forced animation systems, no UI dependencies, and no opinionated architecture.

Controller-first, not demo-first.

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
• Optional steep slope sliding
• 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)

No need to rewrite gameplay logic when changing input workflows.

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
• Lean-based camera roll (Dutch)
• Camera tilt feedback on slopes
• Separate aim camera variants
• Clean integration with camera stacks

Optional module:

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

All camera behavior is visual and editable — no black-box scripts.

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. 

Included Animation Starter Setup

MFPC includes a lightweight first-person animation starter setup to help you quickly prototype:

• Clean first-person arms model (.fbx)
• Humanoid rig compatible
• Basic locomotion animations included
• Ready to use with AnimatorBridge

This setup is fully optional and can be replaced with your own assets without affecting the controller.

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.
