City Builder - Procedural Building Areas!

City Builder handles the part of a city-building game that's tedious to build from scratch: turning open ground into buildable zones. Instead of hand-placing plots for every building, the plugin generates zoning grids procedurally and adapts them to whatever building sizes your project uses.

It's built for city-builder and tycoon-style games where players place structures during gameplay rather than in the editor. A category-filtered carousel handles building selection, thumbnails generate automatically, and the system checks for overlaps and street-facing rules so placement stays valid without extra scripting.

It fits games where a city or town expands as the player unlocks new zones or districts, and any player-driven customization game where structures need to snap into valid, non-overlapping plots without a designer hand-authoring every possible layout.

Common questions

Does the player place buildings at runtime, or is this an editor-only tool? It's built for gameplay-time placement. Players place structures during gameplay rather than in the editor, so the plugin handles overlap prevention and street-facing rules automatically.

Do I need to pre-generate building thumbnails myself? No. Thumbnails for the building/object selection carousel generate automatically from your prefabs.

What input methods are supported for placing buildings? Mouse, keyboard, gamepad, and touch are all supported, so the same zoning system works across PC, console, and mobile builds.
