Grid-Based Builder

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.

Video | Playable Demo | Documentation | Video Update 1.1

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
