# Unity Marching Squares Implementation

I pulled this marching squares implementation out of an old prototype Thrust-a-like game I made for Unity in 2017 

in order to share it, since I think it's quite generic and probably useful for others. It was built for Unity 2017 

but the code is pretty generic.

## Features:

* Given a 2D array of "densities"

  * Building a background mesh for the solid areas

  * Building line renderers for the edges

  * Building EdgeColliders

* Procedurally generating density maps where all areas are reachable

## Classes: 

* Map: Holder for all the data structures for a single map.

* IMapSource: An interface for providing a 2D array of density data to Map. This can be manually authored or generated.

* MeshGenerator: Builds the background mesh for Map, builds colliders, and communicates with the edge generator

* MapEdgeGfx: Builds line renderers for the edges of the solid areas

* MapGenerator: Procedurally generates a map of density data which is always traversable, is an IMapSource

  

## How to use

  

 1. Create a GameObject in your level

 2. Add the Map and MeshGenerator components to it

 3. Add a MeshFilter component (this will hold the mesh)

 4. Add an IMapSource component, e.g. a MapGenerator for a procedural map

 5. Call Map.RefreshMap

   

You'll want to tweak materials etc but everything is standard Unity.
