Setting the Scene

Introduction

The maps and levels in a game are important to make the game interesting to explore. ||scene:Tilemaps|| are used to create maps for the player to explore, which can even be set to prevent the player from moving past certain points.

Step 1

Find ||scene:set tilemap to|| in ||scene:Scene||. Drag it into ||loops:on start||.

tiles.setTilemap(tilemap`level`)

Step 2

Click on the grey box in ||scene:set tilemap to|| to open the tilemap editor. Pick a tile from the gallery (or create your own under My Tiles), and draw a small tilemap for the ||scene:tilemap||.

Run the code, and notice that the tilemap is shown as the background. Each pixel of the drawing in the image editor is shown as a 16x16 square on the screen.

tiles.setTilemap(tilemap`level_0`)

Step 3

Find ||variables:set mySprite to|| and drag it into ||loops:on start|| to create a ||sprites:Sprite||. Open the image editor for the ||sprites:Sprite|| and create an image to represent it on the screen.

tiles.setTilemap(tilemap`level_0`)
let mySprite = sprites.create(img`
. . . . . . f f f f . . . . . .

Step 4

Find ||controller:move mySprite with buttons|| and drag it into ||loops:on start|| after ||variables:set mySprite to||.

This lets the player move the character around the map that is displayed on the screen. However, there is one issue; the player can move straight through the beautiful tiles we designed! This is fixed by changing all of them to be ||scene:Wall|| tiles.

tiles.setTilemap(tilemap`level_0`)
let mySprite = sprites.create(img`
. . . . . . f f f f . . . . . .
. . . . f f f 2 2 f f f . . . .
. . . f f f 2 2 2 2 f f f . . .

. . f f e 2 2 2 2 2 2 e e f . .

. . . . . f f f f f f . . . . .
. . . . . f f . . f f . . . . .
`, SpriteKind.Player)
controller.moveSprite(mySprite)

Step 5

Open the tilemap editor, and click on the wall icon above Gallery. Use it to draw walls over the parts of your tilemap that the player shouldn’t be able to move through.

Example of drawing walls in the tilemap editor

tiles.setTilemap(tilemap`level_1`)
let mySprite = sprites.create(img`
    . . . . . . f f f f . . . . . .
    . . . . f f f 2 2 f f f . . . .

`, SpriteKind.Player)
controller.moveSprite(mySprite)

Complete

Congratulations, your first tilemap is complete! Try to move the character around the screen, or create more types of ||scene:tiles||. If you expand the ||scene:tilemap|| image, you can create a larger map - if you do, use ||scene:camera follow sprite mySprite|| to make it so the camera stays centered on the character you control, so that you can explore the entire map!
