This example shows you how you can go about if you wanted to make a game that uses edges and / or vertices too.
- Import Grids into a clean project.
- Download the package FaceVertexEdge_Example.unitypackage and import it into the same project.
- Open and run the scene FaceVertexEdgeExample.
- You can use the arrows to switch between modes of selection (Faces / Edges / Vertices), and use right click to make all the edges and vertices of a face black.
The example uses three grids. Below is thee tile designs. Normally the tile background would be totally transparent; here we left it slightly opaque to make it clear which component corresponds to which grid.
