# Show Animation
|
|
|
|
Show a group of image frames (pictures) one after another on the [LED screen](/device/screen). It pauses the amount of time you tell it after each frame.
|
|
|
|
```sig
|
|
basic.showAnimation(`
|
|
. . # . . . # # # . . # # # .
|
|
. # # . . . . . # . . . . # .
|
|
. . # . . . . # . . . # # # .
|
|
. . # . . . # . . . . . . # .
|
|
. . # . . . # # # . . # # # .
|
|
`)
|
|
```
|
|
|
|
### Parameters
|
|
|
|
* `leds` is a [String](/reference/types/string) that shows which LEDs are on and off, in groups one after another.
|
|
* `interval` is an optional [Number](/reference/types/number). It means the number of milliseconds to pause after each image frame.
|
|
|
|
### Example: Animating a group of image frames
|
|
|
|
In this animation, each row is 15 spaces wide because
|
|
there are three frames in the animation, and each frame is
|
|
five spaces wide, just like the screen on the BBC micro:bit.
|
|
|
|
```
|
|
basic.showAnimation(`
|
|
. . # . . . # # # . . # # # .
|
|
. # # . . . . . # . . . . # .
|
|
. . # . . . . # . . . # # # .
|
|
. . # . . . # . . . . . . # .
|
|
. . # . . . # # # . . # # # .
|
|
`)
|
|
```
|
|
|
|
### ~hint
|
|
|
|
If the animation is too fast, make `interval` bigger.

|

|
### Example: animating frames with a pause
|
|
|
|
This example shows six frames on the screen, pausing 500 milliseconds after each frame.
|
|
|
|
In this animation, each row is 30 spaces wide because
|
|
there are six frames in the animation, and each frame is
|
|
five spaces wide, just like the screen.
|
|
|
|
```
|
|
basic.showAnimation(`

|
. . . . . # . . . . . . . . . . . . . # . . . . . # . . . .
