Welcome! This tutorial will teach how to program a game of truth or dare on the @boardname@. Let's get started!
|
|
|

### ~
|
|
|
|
Begin by using Show LEDs to create an "up-arrow" image, which will point to someone.
|
|
|
|
```blocks
|
|
basic.showLeds(`
|
|
. . # . .
|
|
. # # # .
|
|
# # # # #
|
|
. . # . .
|
|
. . # . .
|
|
`)
|
|
|
|
```
|
|
|
|
Now let's create a condition to know when button `A` is pressed so that we can display "truth" or "dare" on the @boardname@. We want the @boardname@ to randomly choose whether to display "truth" or display "dare". We can use accomplish this by using `pick random (1)`.
|
|
|
|
```blocks
|
|
basic.showLeds(`
|
|
. . # . .
|
|
. # # # .
|
|
# # # # #
|
|
. . # . .
|
|
. . # . .
|
|
`)
|
|
input.onButtonPressed(Button.A, () => {
|
|
let random = Math.random(2)
|
|
})
|
|
```
|
|
|
|
Now let's display the appropriate message for each scenario of `random`.
|
|
|
|
```blocks
|
|
basic.showLeds(`
|
|
. . # . .
|
|
. # # # .
|
|
# # # # #
|
|
. . # . .
|
|
. . # . .
|
|
`)
|
|
input.onButtonPressed(Button.A, () => {
|
|
let random = Math.random(2)
|
|
if (random == 0) {
|
|
basic.showString("TRUTH")
|
|
} else {
|
|
basic.showString("DARE")
|
|
}
|
|
})
|
|
```
|
|
|
|
|
|
|
|
Notice how the arrow didn't display again after pressing button `A`. Let's add a line of code that displays the arrow again.
|
|
|
|
```blocks
|
|
basic.showLeds(`
|
|
. . # . .
|
|
. # # # .
|
|
# # # # #
|
|
. . # . .
|
|
. . # . .
|
|
`)
|
|
input.onButtonPressed(Button.A, () => {
|
|
let random = Math.random(2)
|
|
if (random == 0) {
|
|
basic.showString("TRUTH")
|
|
} else {
|
|
basic.showString("DARE")
|
|
}
|
|
basic.showLeds(`
|
|
. . # . .
|
|
. # # # .
|
|
# # # # #
|
|
. . # . .
|
|
. . # . .
|
|
`)
|
|
})
|
|
|
|
```
|
|
|
|
* Run your program: Press button A!
