Creating A Tileset
Add TileMap
In your game scene, add a 'TileMap' as a child of your game node.
Create TileSet
In the inspector window, create a new tileset.
Import Tileset
At the bottom of the screen, click 'TileSet'. If you're using the demo assets, drag in 'world_tileset.png' to this screen. Click 'yes' when It asks if you want to automatically create tiles in the atlas.
Paint Environment
Using the paint tool in the TileMap window, select a tile and start to paint in your environment to the game scene. Get creative!

Add Physics Layer
In the inspector, add a new physics layer to the tilemap. Back in the TileSet window, click the 'paint' tab and paint the new physics layer onto each tile you want to have collision.
