Unity 3D – Third Person Controller

Reusable third-person controller prototype built in Unity.

This project is a small standalone testbed for:

• Player movement in 3D
• Third-person camera control
• Basic movement animations
• Input System setup

A lot of the logic here can be reused in other projects.

1. Project Overview

This repository contains a general 3D third-person controller in Unity.
It focuses on clean, readable code and modular systems that can be dropped into other projects.

Implemented

• New Input System setup (actions for move, look, jump, sprint - even if some are WIP)
• Player movement on flat ground (forward / backward / strafe)
• Camera follow + orbit around the player
• Basic movement animation (idle / walk or run blend) driven by movement input
• Jumping (with proper grounding checks)
• Sprinting (with speed multiplier + animation)
• Falling / landing states
• Better behaviour on stairs and slopes
• Extra polish on camera collision and smoothing

In Progress / Planned

• TBD

2. Gameplay / Controls

Default keyboard & mouse setup:

• W / A / S / D – Move the character
• Mouse movement – Rotate camera around the player
• Space – Jump (logic currently in progress)
• Left Shift – Sprint (logic currently in progress)

These are mapped using Unity’s New Input System via an InputActions asset, with actions such as:

• Player/Move – Vector2 movement
• Player/Look – Mouse delta / right stick
• Player/Jump – Button
• Player/Sprint – Button

3. Technical Details

• Engine: Unity (2022.3.62f2)
• Render Pipeline: URP
• Language: C#
• Target Platform: PC (Windows)

Main Systems

• Player Movement

  • Reads input from the New Input System
  • Moves the player relative to camera direction
  • Normalized movement to keep consistent speed

• Camera Controller

  • Smooth follow of the player
  • Mouse-controlled orbit
  • Clamped vertical rotation to avoid flipping under/over the level

• Animation Controller

  • Animator with basic states (Idle, Walk/Run)
  • Blend based on movement magnitude
  • Hooks ready for future states (Jump, Fall, Land, Sprint)
