|
|
## Introduction @showdialog
|
|
|
|
** Let's explore the depths of space! **
|
|
|
|
In this tutorial, you'll design a spaceship for your journey.
|
|
|
|
|
|
|
|
## Set the scene
|
|
**Give 'em something to look at** 🔭
|
|
|
|
---
|
|
|
|
|
|
► Drag the ``||scene:start screen [confetti] effect ⊕||`` from the ``||scene:Scene||`` category and
|
|
into the ``||loops:on start||`` block that's already in the workspace.
|
|
|
|
► Next, select ``||scene:star field||`` (instead of ``||scene:confetti||``) from the dropdown
|
|
and watch as you blast into space! 🚀
|
|
|
|
|
|

|
|
|
|
|
|
```blocks
|
|
// @highlight
|
|
effects.starField.startScreenEffect()
|
|
```
|
|
|
|
|
|
|
|
## Draw your ship
|
|
**🧑🏿🚀 Time to choose our ship! 👩🏾🚀**
|
|
|
|
---
|
|
|
|
► From the ``||sprites:Sprites||`` category, drag the ``||variables:set [mySprite] to sprite [ ] of kind [Player]||``
|
|
block and place it at the end of the ``||loops:on start||`` container.
|
|
|
|
► Click on the grey box in the middle of your
|
|
``||variables:set [mySprite] to sprite [ ] of kind [Player]||`` block
|
|
to design a ship of your own! Are you a rusty pile of scraps or a sleek, futuristic rocket?
|
|
|

|
|
|
|
**Tip:** Don't feel like drawing your ship? Once you're in the sprite editor,
|
|
flip to the gallery and choose from premade images.

## Control your ship
|
|
|
|
🌟 Let's get your ship moving 🌟
|
|

|
|
|
|
► Find the ``||controller:move [mySprite] with buttons ⊕||`` block
|
|
and drag it into the bottom of the ``||loops:on start||`` container.
|
|
|
|
** Now try moving your ship around on the game screen! **
|
|
Your ship will move with the joystick, arrow keys, or **W A S D** keys.

|
## Stay in screen
|
|
|
|
**Uh-oh, if you move off screen, your ship disappears!**
|
|
|
|
---
|
|
|
|
► To keep your ship from exploring beyond the edges, find
|
|
the ``||sprites:set [mySprite] stay in screen <on>||`` block and
|
|
snap it in at the end of the program.
|
|
|
|
|
|
|
|
```blocks
|
|
effects.starField.startScreenEffect()
|
|
let mySprite = sprites.create(img`
