This [guided tutorial](https://test.microbit.co.uk/td/lessons/blinks-rectangle/tutorial) will help you show an animation forever!
|
||
|
|
||
|
First, let's make a small rectangle blink forever.
|
||
|
|
||
|
```blocks
|
||
|
basic.forever(() => {
|
||
|
basic.showAnimation(`
|
||
|
. . . . . . . . . .
|
||
|
. # # # . . . . . .
|
||
|
. # # # . . . . . .
|
||
|
. . . . . . . . . .
|
||
|
. . . . . . . . . .
|
||
|
`, 400)
|
||
|
})
|
||
|
```
|
||
|
|
||
|
**Challenge 1**
|
||
|
|
||
|
Let's begin creating our explosion effect by adding another rectangle animation that displays a slightly larger rectangle after the first one.
|
||
|
|
||
|
```
|
||
|
basic.forever(() => {
|
||
|
basic.showAnimation(`
|
||
|
. . . . . . . . . .
|
||
|
. # # # . . . . . .
|
||
|
. # # # . . . . . .
|
||
|
. . . . . . . . . .
|
||
|
. . . . . . . . . .
|
||
|
`, 400)
|
||
|
basic.showAnimation(`
|
||
|
. . . . . . . . . .
|
||
|
# # # # # . . . . .
|
||
|
# # # # # . . . . .
|
||
|
# # # # # . . . . .
|
||
|
. . . . . . . . . .
|
||
|
`, 400)
|
||
|
})
|
||
|
```
|
||
|
|
||
|
**Challenge 2**
|
||
|
|
||
|
To finalize our explosion effect, let's add a rectangle that is bigger than the last two we have created.
|
||
|
|
||
|
```
|
||
|
basic.forever(() => {
|
||
|
basic.showAnimation(`
|
||
|
. . . . . . . . . .
|
||
|
. # # # . . . . . .
|
||
|
. # # # . . . . . .
|
||
|
. . . . . . . . . .
|
||
|
. . . . . . . . . .
|
||
|
`, 400)
|
||
|
basic.showAnimation(`
|
||
|
. . . . . . . . . .
|
||
|
# # # # # . . . . .
|
||
|
# # # # # . . . . .
|
||
|
# # # # # . . . . .
|
||
|
. . . . . . . . . .
|
||
|
`, 400)
|
||
|
basic.showAnimation(`
|
||
|
# # # # # . . . . .
|
||
|
# # # # # . . . . .
|
||
|
# # # # # . . . . .
|
||
|
# # # # # . . . . .
|
||
|
# # # # # . . . . .
|
||
|
`, 400)
|
||
|
})
|
||
|
```
|
||
|
|
||
|
**Challenge 3**
|
||
|
|
||
|
If you notice, the rectangle explodes fairly slow. Let's make it explode faster by decreasing the intervals of the animation from 400 to 200.
