Grid-Based Builder v4.26+

This asset allows you to build various objects that can snap to a grid, all while taking into account terrain topography, surface types, as well as other constraints.

Features:

Completely made in blueprints

Grid size is practically unlimited*

Customizable grid cell size

New objects can be created and customized using data tables

Ability to check elevation differences during construction

Ability to check whether there are any units present in the area of construction. If there are any - construction won’t be possible

The new Update 1.1 adds examples of the construction of complex asymmetrical walls with diagonal elements and roads

Contains an example building that can only be built on a specific resource

Contains an example building that can only be built on a certain surface with a specific texture (Grass / Stone)

Contains an example of a type of construction where several objects can be constructed in a line by mouse-dragging (Wall)

Contains an example of a “Painting” type of construction, where objects will be built continuously as long as the left mouse button is held

Contains an example building that can only be built within a certain radius of another building, etc.

Resource system: resources are spent during construction, but if there aren't enough, construction will be blocked. Part of the spent resources can also be returned upon demolition

Demolition tool, which is meant for deconstruction of objects

Objects can be outlined when a cursor is hovered over them. By default, only 3 colors are used, one for each of the example factions — player, neutral and enemy.

Objects can be rotated by 90 degrees by default

Basic functionality for a building damage system - objects can receive damage, change their HP values, can be destroyed once their HP runs out

Auxiliary boundary blueprint that is used for restriction of all space available for construction. Only a single one can be built

Auxiliary boundary blueprint that is used for blocking construction only on certain areas of the map. More than one can be built and these are used to fine-tune available construction space if a complex shape is needed

Buildings can be placed not only at runtime, but also in the editor. It is also possible to attach an object to the grid in the editor as well

Has several styles for visual display of building construction

Has basic demo units that are able to to patrol an area and attack nearby buildings


Asset also has a demo UI which includes:

Resource panel widget with animations of gradual change in the number of available resources, and a blinking animation used to show lack of necessary for construction resources

Construction menu widget with building icons that, when clicked on, will activate an object to be built. Displayed number of cells in the menu can be changed.

Description widget, which is used to show a description for a selected buildable object

HP bar widget, which is displayed above a building when hovered over or selected, it also changes color based on remaining HP
