Terrain Grid System is an advanced grid generator and territory/cell highlighter with powerful features for both Terrain and 2D grids.

Are you working on a strategy or RTS game and want to quickly highlight cells under some units or show territories under control?

Do you wish to allow the player choose a destination over a terrain?

Or do you simply want an interactive grid over any mesh?

This is the perfect asset for that!

**Key Features**

– Easy to use. Add Terrain Grid System script to your terrain, gameobject or group of objects to instantly attach and configure the grid. Or drag & drop the prefab to use it in stand-alone mode (no terrain mode).

– Configurable, fully interactive and fast grid generation, including Voronoi tessellation, box/squared, rectangular and hexagonal types.

– Compatible with Unity standard terrain, mesh-based terrains or any gameobject with a mesh.

– Change visibility, color or texture of cells from Unity editor with the integrated grid editor.

– Produces highly optimized grid mesh with reduced vertex count.

– Two levels of regions: cells and territories.

– Fastest selectable and highlighting system for both cells and territories.

– Coloring and fade out support for both cells and territories.

– A* Pathfinding for boxed and hexagonal grids with customizable cell weights and obstacles.

– Easily define blocking cells or assign cells to different groups (zones, obstacles, custom navigatable paths, …)

– Get neighbours or cells in range according to crossing cost, max steps or cell group masks

– LOS (Line of Sight) functions.

– Easy rectangle selection of cells.

– Different positioning options for best mesh adaptation to the terrain, including scaling and positioning inside terrain boundaries, maximum terrain slope, minimum altitude, …

– Control the visibility of individual cells using API or alpha texture mask.

– Define territories using a color texture or the embedded grid editor!

– Supports multiple grids in the scene as well as multiple grids per terrain.

– More than 20 demo scenes included with useful sample code!

** Technical Features **

– Can work alone (as planar grid), with Unity terrain and mesh based terrains.

– Supports one or more grids per standard Unity terrain object.

– Multi-tile standard terrain currently requires one separate grid per each terrain.

– Multi-tile mesh-based terrains can be covered by a single grid.

– Works with orthographic and perspective cameras.

– Compatible with Built-in, URP and HDRP pipelines.

– Compatible with Unity 2019 LTS and up.

– Extensive API (C#) for controlling and managing the grid, including selectable cells/territories, finding neighbours and merging cells.

– Full source code included (C#).
