Overview

X Marks the Spot was my first Unity game developed in 2022-23 during my time at the University of Salford (Later updated in 2025). The project served as a way to demonstrate my ability to create a polished, optimized game experience. The game utilizes various Unity technologies, such as occlusion culling and LOD (Level of Detail), to ensure smooth performance and a visually appealing experience.

This is an adventure game where the player embarks on a quest to find a buried treasure on a mysterious island. Along the way, the player will encounter obstacles, collect gems while climbing the mountain, and navigate a perilous tunnel filled with traps. The ultimate goal is to find and unearth the treasure hidden at the top.

Development & Features

Developed using Unity 6.1 (6000.1.3f1) and C# 9.0. Key milestones included:

• Implemented core game mechanics: climbing, jumping, obstacle interaction. Recreated standard asset first person controller to use new Unity’s new Input System and tailor it to the game.
• Proximity prompts and text hints.
• Designed multi-environment levels including mountainous terrain and trap-filled tunnels.
• Collision optimization to reduce processing. Unnecessary Mesh Colliders were removed in favor of more efficient colliders.
• Optimized performance using occlusion culling, Level of Detail (LOD), and projectile lifecycle animations.
• Implemented full controller support featuring context-sensitive input glyphs and event-driven input handling. (Unfortunately, no console support as I lack a devkit)
• Settings panel including difficulty settings.
• Created tools for asset and scene management. Tools included terrain tree management and scripts to detect missing functions in Unity Events to handle function renames.
• Automated build pipelines with GitHub Actions.
