Games

Aquaman: Home is Calling

Aquaman: Home is Calling

2018, Roblox, Lua

Roblox Game

Aquaman: Home is Calling is a multiplayer MMORPG-esque underwater experience wherein the player becomes Aquaman to overcome trials to become the King of Atlantis. This game was sponsored by Warner Brothers and produced by Roblox in order to promote the then-upcoming Aquaman film. Working as part of a team for several months, we implemented custom solutions to problems like underwater pathfinding with navigation mesh generation, enemy AI, a polymorphic Unit system to model any combatant (be it a player or an AI-controlled NPC), and a state management system named Aurora.

Libraries

Aurora

Aurora

GitHub

Aurora is a library that can manage status effects (known as “Auras”) in your Roblox game. These Auras are much akin to “buffs” and “debuffs” as seen in many games. Using Aurora can help you stay sane while managing complex game state when multiple parts of your game need to keep track of or change the same resource. It’s like Redux, but for games!

Cmdr

Cmdr

2018, Lua

Website, GitHub

Cmdr is a fully extensible and type safe command console for Roblox developers. Cmdr is designed specifically so that you can write your own commands and argument types, so that it can fit right in with the rest of your game. In addition to the standard moderation commands (teleport, kill, kick, ban), Cmdr is also great for debug commands in your game (say, if you wanted to have a command to give you a weapon, reset a round, teleport you between places in your universe).

Radial Sprite Sheet Generator

Radial Sprite Sheet Generator

2018, TypeScript, React, Lua

Web App, GitHub

RadialSpriteSheetGenerator is a project that generates radial sprite sheets (what a surprise!). It is another project born out of necessity, because Roblox doesn’t support clipping masks for images. It can generate a stereotypical “loading ring” or “circular progress indicator” out of any image you choose, paired with a Lua module that lets you pass in a percentage and it will autonatically pick the closest image from the sprite sheet.
