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 over their project architecture.

It provides a solid, production-ready foundation for FPS, immersive sims, walking simulators, and narrative experiences — without forcing opinions about animation, UI, or gameplay systems.

MFPC is controller-first, not demo-first.

Movement & Player State

• Walk, Sprint, and Crouch
• Hold or Toggle modes (configurable)
• Forward-only sprint restriction
• Lean left / right with smooth interpolation
• Jump with gravity tuning
• Collision-safe auto-uncrouch
• Optional auto-unsprint when stopping movement (for 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)

Choose the input workflow that fits your project — or swap later without rewriting 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)
• Separate aim camera variants
• Clean integration with camera stacks

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

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

Creating new surface sounds:

• Create a new SurfaceSFX asset
• Assign terrain layers or
• Add an ObjectLayer component to scene objects

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
