Introduction to the Grid-Based Builder

The Grid-Based Builder is a versatile asset designed to help developers create complex construction mechanics. It allows you to build various objects that snap precisely to a grid. Furthermore, the system is built entirely in Blueprints, making it accessible for developers who prefer visual scripting over manual coding.

This system goes beyond simple placement by accounting for terrain topography and surface types. Therefore, you can ensure that buildings only appear where they logically belong. Whether you are creating a strategy game or a simulation, this tool provides a solid foundation for building mechanics.

Core Construction Features

One of the primary strengths of the Grid-Based Builder is its flexibility. The grid size is practically unlimited, and developers can easily customize the cell size to fit their specific project needs. Additionally, new objects are created and managed using data tables, which streamlines the customization process.

Construction logic includes several advanced checks to maintain gameplay balance. For example, the system can check for elevation differences during the building phase. It also detects if units are present in the construction area, blocking placement if the space is occupied.

Advanced Building Methods

The developer has included various placement styles to enhance the user experience. You can use a line-dragging method to build several objects, such as walls, in a single motion. Alternatively, a “painting” mode allows objects to be built continuously as long as the mouse button is held down.

Update 1.1 introduces even more complexity to the system. It adds support for asymmetrical walls with diagonal elements and dedicated road construction. Moreover, specific constraints can be applied, such as requiring a building to be placed within a certain radius of another structure.

Resource Management and Damage Systems

A functional resource system is integrated directly into the Grid-Based Builder. Resources are spent during construction, and the system will automatically block building if the player lacks the necessary materials. However, part of these resources can be returned to the player upon demolition using the included deconstruction tool.

The asset also features a basic damage system for all constructed objects. Buildings can receive damage and track their health through HP values. Once a building’s HP reaches zero, it is destroyed. This adds a layer of tactical depth to any game utilizing these mechanics.

Visual Feedback and UI Integration

The Grid-Based Builder provides clear visual feedback for players. Objects are outlined when hovered over, using three distinct colors to represent player, neutral, and enemy factions. Objects can also be rotated by 90 degrees to ensure perfect alignment within the game world.

The included demo UI features several helpful widgets. These include a resource panel with animations for material changes and a construction menu with customizable icons. Additionally, HP bars appear above buildings when selected, changing color based on the remaining health of the structure.

Editor and Map Tools

Efficiency is key during development, which is why buildings can be placed both at runtime and directly within the editor. The asset also provides auxiliary boundary Blueprints. These tools allow developers to restrict construction to specific zones or block building in complex shapes across the map.

In conclusion, the Grid-Based Builder is a feature-rich solution for anyone needing a professional construction system. With its resource management, terrain awareness, and flexible placement modes, it simplifies the creation of grid-based gameplay environments.
