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 over their projects — not a rigid framework.

Designed around Cinemachine and modern Unity workflows, MFPC provides responsive movement, polished camera presentation, optional gameplay modules, and clean extension points while remaining independent from animation systems, UI, networking, or project-specific architecture.

MFPC supports both desktop, gamepad and mobile workflows. A complete mobile demo scene using Unity's New Input System and On-Screen Controls is included for touch-based projects.

Whether you're building an FPS, immersive sim, horror game, walking simulator, or narrative experience, MFPC gives you a solid first-person foundation that integrates cleanly into existing projects instead of forcing you to adapt to it.

Controller-first, not demo-first.

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)
• Optional advanced Headbob module
• Automatic Depth-of-Field focus
• Camera swing while turning
• 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
• Simplified pause system

Optional module:

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

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

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
• Simplified pause system

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)
• Mobile touch controls (New Input System only)
• Sensitivity parity between input systems
• Frame-rate independent mouse smoothing
• No need to rewrite gameplay logic when changing input workflows

No need to rewrite gameplay logic when changing input workflows. The included mobile demo scene uses Unity's New Input System and On-Screen Controls. Mobile support is therefore available when using the New Input System controller.

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.
