I can't create a grid of hexagonal tiles

As a first step in creating a demo first game, I want to create a grid of hexagonal tiles, view them from top down, and have them change colours when I click on them.

I believe I need to use Tilemap for this, but I have two problems:
1) The Tilemap does not seem to be visible
2) There does not seem to be a way to set the size of the tilemap
3) I don't know how to access the individual cells from the tilemap.

There's also the possibility that Tilemap is not the right class for this at all.

Some advice would be appreciated

 

It’s definitely the right solution for tilemaps in general.

The tilemap object doesn’t really show up until you add tiles to it. You can do that using the Tile Palette window (Window -> 2D -> Tile Palette). First click the button to create a new tile palette object, then create tiles by dragging sprites into the tile palette. Then you can just paint those tiles onto the tilemap in the editor window.

Accessing individual tiles in the tilemap, depending on what you want to do, but most useful are the Tilemap.GetTile and Tilemap.SetTile methods.

 

OK thanks, I'll try that.
