The Grid-Based Builder v4.26+ is a game resource pack that enables players to construct various objects that snap to a grid, taking into account terrain topography, surface types, and other constraints. Fully built in Blueprints, the system offers a practically unlimited grid size and customizable grid cell dimensions. New objects can be created and customized via data tables. The builder includes elevation difference checks during construction and prevents building if units are present in the construction area.
Updates introduce examples of complex asymmetrical walls with diagonal elements and roads, as well as buildings that can only be constructed on specific resources or surfaces (such as grass or stone). The system supports mouse-dragging to build walls in a line and continuous “painting” style construction while holding the left mouse button. Certain buildings can only be constructed within a specific radius of another building.
A resource system is included, where resources are consumed during construction—construction halts if resources are insufficient, and some resources can be recovered upon demolition. A dedicated demolition tool allows for object deconstruction. Objects can be outlined on hover with three default colors (player, neutral, enemy), and can be rotated by 90 degrees by default. A basic damage system allows buildings to take damage, have HP values, and be destroyed when HP reaches zero.
The system features auxiliary boundary blueprints: one for restricting all construction space, and multiple for blocking construction in specific map areas to enable complex shape configurations. Buildings can be placed both in real-time and in the editor, including attachment to the grid during editing. Multiple visual styles are available for construction display. Demo units patrol areas and attack nearby buildings.
The included demo UI features a resource panel with animated resource changes and blinking indicators for resource shortages, a construction menu with customizable cell counts and building icons, a description widget for selected objects, and an HP bar that displays above buildings and changes color based on remaining HP.
