Coding challenges for flipping bird. #docs
|
|
|
|
## Before we get started
|
|
|
|
Complete the following guided tutorial:
|
|
|
|
* [tutorial](/lessons/flipping-bird/tutorial)
|
|
|
|
At the end of the tutorial, click `keep editing`. Your code should look like this:
|
|
|
|
```
|
|
counter = 0
|
|
input.onGesture(Gesture.Shake, () => {
|
|
counter = counter + 1
|
|
if (math.mod(counter, 2) == 1) {
|
|
basic.plotImage(`
|
|
# # . # #
|
|
. . # . .
|
|
. . . . .
|
|
. . . . .
|
|
. . . . .
|
|
`)
|
|
}
|
|
})
|
|
```
|
|
|
|
### Challenge 1
|
|
|
|
We handled the case of when `math->mod(counter,2) = 1`. We haven't done anything when the remainder is 0! Add an if statement to handle this case.
|
|
|
|
```
|
|
counter = 0
|
|
input.onGesture(Gesture.Shake, () => {
|
|
counter = counter + 1
|
|
if (math.mod(counter, 2) == 1) {
|
|
basic.plotImage(`
|
|
# # . # #
|
|
. . # . .
|
|
. . . . .
|
|
. . . . .
|
|
. . . . .
|
|
`)
|
|
}
|
|
if (math.mod(counter, 2) == 0) {
|
|
}
|
|
})
|
|
```
|
|
|
|
### Challenge 2
|
|
|
|
### @video td/videos/flipping-bird-2
|
|
|
|
Inside of that `if` statement you created in challenge 1, add `basic->plot image()` and display an upside down flying bird.
|
|
|
|
```
|
|
counter = 0
|
|
input.onGesture(Gesture.Shake, () => {
|
|
counter = counter + 1
|
|
if (math.mod(counter, 2) == 1) {
|
|
basic.plotImage(`
|
|
# # . # #
|
|
. . # . .
|
|
. . . . .
|
|
. . . . .
|
|
. . . . .
|
|
`)
|
|
}
|
|
if (math.mod(counter, 2) == 0) {
|
|
basic.plotImage(`
|
|
. . . . .
|
|
. . . . .
|
|
. . . . .
|
|
. . # . .
|
|
# # . # #
|
|
`) // ***
|
|
}
|
|
})
|
|
```
|
|
|
|
* `Run` the code to see if it works as expected.
|
|
|
|
**Challenge 3**
|
|
|
|
Display a check mark and question mark instead of flipping birds. Or better yet, come up with your own pair of opposites to display!
