ClimbGame — COMP602 Unity 3D Project

A 3D puzzle-platformer built in Unity where players navigate environments, solve spatial puzzles, and overcome obstacles through climbing mechanics.

About the Game

ClimbGame is a third-person 3D platformer built entirely from scratch in Unity. The player navigates a series of environments by climbing, jumping, and solving spatial challenges. The focus was on building solid game architecture — responsive controls, physics-driven collision, and a clean state machine to manage player behaviour.

Features

• Player controller — smooth movement, jump, and climb mechanics built with Unity's physics engine
• Collision detection — context-aware surface detection for grounded, airborne, and climbable states
• State machine architecture — C# state machine managing player states (Idle → Run → Jump → Climb → Fall)
• Environment design — multi-level layout with obstacles, ledges, and climbable geometry
• Camera system — follow camera with smooth interpolation

Getting Started

Prerequisites

• Unity Hub with Unity 2022.3.43f1 LTS installed
• Git

Option 1 — Play the game

git clone https://github.com/All-Missing/COMP602_Project10_New.git

1. Open Unity Hub → click Add → navigate to the cloned folder
2. Select the COMP602_Project10_New folder and open the project
3. Inside the project, locate and launch ClimbGame to play

Tip: The Release branch contains the final, submission-ready build.

Option 2 — Open in Unity editor (development / testing)

git clone https://github.com/All-Missing/COMP602_Project10_New.git

1. Open Unity Hub → Add → select the Project10 folder
2. Unity will import all assets automatically
3. Open the main scene and press Play in the editor

Key Implementation Details

State Machine (C#)
Player behaviour is managed through a finite state machine. Each state (Idle, Running, Jumping, Climbing, Falling) encapsulates its own input handling, physics interactions, and transition conditions — keeping game logic clean and extensible.

Collision & Physics
Surface detection uses Unity's Physics.Raycast and CharacterController to distinguish ground, walls, and climbable surfaces, enabling context-sensitive responses without hardcoding per-object logic.
