Name the new file “grid” (the editor will save the file as “grid.tilemap”). Right click the main folder and select New ▸ Tile Map. Now you have a tilesource ready for use so it’s time to create the playfield tilemap component: This is to prevent visual artifacts around the tiles that have graphics all the way out to the edge. Note that the Extrude Borders property is set to 1 pixel. This will split the 32⨉32 pixel image into 4 tiles, numbered 1–4. The Width and Height properties should be kept at 16. Set the Image property to the graphics file you just imported. Name the new file “snake” (the editor will save the file as “snake.tilesource”).
Right click the main folder and select New ▸ Tile Source. Since tilemaps fetch their graphics from a Tilesource so you need to create one: A tilemap allows you to set and read individual tiles, which suits this game perfectly. Right click the image, save it to your local disk and drag it to a location in the project folder.ĭefold provides a built-in Tilemap component that you will use to create the playfield. One 16x16 segment for the snake, one for obstacles and one for the food. Very little is needed in terms of graphics. The reason why you want to do this is because the game will be drawn on a grid where each segment is going to be 16x16 pixels, and this way the game screen won’t cut off any partial segments. Open the game.project settings file and set the dimensions of the game to 768⨉768 or some other multiple of 16. Select a location for the project on your local drive.This snake also crawls on a playfield that contains obstacles. There are a lot of variations on this game, this one features a snake that eats “food” and that only grows when it eats. This tutorial walks you through the process of creating one of the most common classic games you can attempt to recreate.
