If you look at the wall tile set sprite shown below, you can see that the upper left position (tile index 0) is empty, for example: Essentially a tile set layer in the room editor will always have tiles, with the tile being used initially set as the empty tile in the tile set (note that even if you have a tile at the empty position, it will not be drawn). To create a tile set the sprite will need to have each tile spaced on a grid, and the very first tile should be blank, as this is the 'empty' tile that is used for deleting. You can also animate tiles, but there are certain caveats associated with that too, which we'll discuss later in this tutorial.įor now though, this tutorial is going to explain how to create a basic tile set resource.Ī tile set will need to have been assigned a Sprite Resource before you can use it.

You are also limited when it comes to rotating tiles, as they can only be rotated 90° or mirrored along the vertical axis or flipped along the horizontal axis. When placing your tiles in the Room Editor you can overlap tiles by placing them on different layers, but the tile set itself is one tile per cell.

The grid does not have to be square nor does it have to be a power of two - so a tile set that uses 20x45 grid cells would be fine - and you can only have one tile per grid cell. To start with tiles are always placed on a grid. Now, tile sets do come with some caveats. They are very fast to draw and require little processing power, making them ideal for creating platforms, background scenery and anything else that objects may not have to directly interact with. A tile set is a graphical resource used to add images into your game but without the need for using an object. The tile set editor is where you can take a sprite resource and convert it into a tile set for use within your game rooms. In this tutorial we are going to look at the GameMaker Studio 2 Tile Set Editor.
