Tile-Based Puzzle Mechanics

Introduction

This project focused on designing and implementing interactive tile-based mechanics within a grid-based system. The goal was to create gameplay elements that could interact with the player and other entities in meaningful ways, including cracked tiles, magnetic tiles, and a timed activation tile (currently a work in progress).

Each mechanic was built using Unreal Engine Blueprints and designed to work within an existing tile framework that handled movement, neighbors, and entity interaction. Throughout the project, I focused on making systems modular, reusable, and visually clear to the player, while also exploring how multiple mechanics could work together to create more engaging gameplay sequences.

What Went Right

Building on an Existing System

One of the biggest wins was learning how to work with the provided tile system instead of fighting against it. Functions like neighbor checks and tile replacement already handled most of the heavy lifting. Once I leaned into that, development became much smoother and more efficient.

Modular Blueprint Design

I focused on keeping everything modular instead of hardcoding behavior into a single blueprint. By using variables like tile types and entity types, I was able to reuse logic across multiple mechanics. This made debugging easier and allowed for expansion without breaking existing systems.

Expanding Beyond Requirements

Instead of stopping once the mechanics worked, I designed multiple levels that used these systems together in sequence. This helped me better understand how individual mechanics interact in real gameplay scenarios and gave the project a more complete and polished feel.

Using Engine Features Properly

Switching from string-based level loading to soft object references was a major improvement. It made the system cleaner and introduced better Unreal practices such as asset references and editor dropdown selection, improving usability and reducing error potential.

Debugging and Iteration Mindset

When systems didn’t work as expected, I worked through them step by step instead of scrapping them. This improved my ability to read Blueprint logic and understand how data flows through systems, which was a major area of growth during this project.

What Went Wrong

Overcomplicating Early Logic

Early on, I over-engineered solutions instead of using existing systems. This created unnecessary complexity and made debugging more difficult. In the future, I would prioritize simpler implementations first.

Working Too Fast Without Verifying

At times I moved too quickly, connecting multiple parts of a system without testing incrementally. This led to avoidable debugging issues and required backtracking.

Blueprint Organization

Some Blueprint graphs became messy during experimentation, making them harder to debug. While I improved this later, I would prioritize organization and structure much earlier next time.

Misunderstanding Engine Systems

I initially struggled with object references and how certain nodes expected input. This slowed progress, but ultimately improved my understanding of Unreal systems.

Choosing the Wrong Initial Approach

For the timed tile mechanic, I initially tried solving the problem visually instead of using the existing tile replacement system. This led to unnecessary complexity before correcting course.

Development Workflow

This project was developed using structured task tracking and version control workflows. Progress and implementation steps were managed through ClickUp task boards, while Perforce was used for revision control to track changes and maintain project stability.

Conclusion

This project was a strong step forward in both design and development. I improved my approach to problem-solving, system design, and debugging while learning to trust and leverage existing systems.

Moving forward, I want to continue improving Blueprint organization, slow down my workflow to reduce errors, and focus on building clean, modular systems that can scale into more complex gameplay.
