Colony Sim Engine for RPG Maker MZ
A downloadable tool
Colony Sim Engine is a cutting-edge plugin for RPG Maker MZ that lets you build full-fledged colony sims, city builders, and base-building games without fighting the engine. It gives you deep, modular systems for managing citizens, resources, buildings, and production.
The plugin includes:
Time Controls: Pause, play, or speed up the game; all in-world systems scale accordingly.


Map Movement & Point-and-Click: Smooth camera scrolling, hover highlights, selection, and actions.
Build Mode: Place building previews, queue construction, and watch projects progress step by step. Finished buildings unlock new jobs, production lines, and upgrade paths.

Citizens & Tasks: Citizens pick tasks based on priority, proximity, availability, and skills. Tasks are modular and can be skill-specific. Floating text shows task progress and level-ups.
Skills & Leveling: Citizens gain XP for tasks. Levels improve speed and output quality. Each skill is customizable, and citizens’ skills and levels are visible in the Behaviors window.
Needs & Mood: Hunger, rest, comfort, and safety impact citizen behavior and productivity. Developers can define custom stats and decay rates.

Farming & Resource Gathering: Prepare soil, plant, water, follow seasons, and harvest crops. Resource zones are linked to yield, respawn times, tools, and skills. Each harvesting task is tracked separately.

Crafting & Production: Recipes with input/output items, work times, and quotas. Citizens craft only until quota targets are met. Tasks are modular and skill-specific.
Buildings & Upgrades: Upgrade buildings and workstations for efficiency and productivity. Buildings can produce over time without active work.
Research System: Optional research tree unlocks buildings, recipes, and bonuses. Research can require idle citizens, skill levels, and building prerequisites.
Money & Shipping: Ship products and track gold. HUD updates are tied to shipment settings.
Animations & VFX/SFX: Task-specific looping animations, visual effects, and sound effects. Citizens face the correct target during tasks.
Alerts & Events: Fully customizable alerts with text, sound, priority, screen position, and throttling. Scheduled or random events affect resources, buildings, and citizens.
Custom UI & Assets: Replace built-in icons, buttons, cursors, alerts, overlays, and window skins. All windows are draggable and configurable.
Inspector & Debugging: Click any citizen or building to see live stats, inventory, skills, and current tasks (optional visibility).
Story & Tutorials: Trigger story or tutorial messages at game start or via in-game events. Developers can guide players without hardcoding sequences.
Flexible Developer Tools: Define global fonts, floating text, resource respawn times, citizen spawn locations, task IDs, quotas, research requirements, and more.
Important Note
While the plugin has been tested thoroughly, bugs are to be expected in a system of such complexity. Please send all bug reports, feedback, and requests for new features to bitqueststudio at gmail dot com.
I will be prioritizing patches, polish, and improvements for this plugin for the foreseeable future in order to round it out.
