# truth or dare activity

a multi-player game that forces each player to reveal a secret or something funny. #docs

To create a new script, go to the [Create Code](/microbit/create-code) page and tap *New Project* under **Touch Develop**.
|
||
|
|
|
||
|
|
Begin by plotting an "up-arrow" image, which will point to someone.
|
||
|
|
|
||
|

|

```
|
||
|
|
|
||
|
|
* Run your program and look at the arrow!
|
||
|
|
|
||
|
|
Now let's create a condition to know when button `A` is pressed so that we can display "truth" or "dare" on the BBC micro:bit.
|
||
|
|
|
||
|
|
```
|
||
|
|
basic.showLeds(`

. . # . .

|

|
`, 400)
|
||
|
|
input.onButtonPressed("A", () => {
|
||
|
|
})
|
||
|
|
```
|
||
|
|
|
||
|
|
We want the BBC micro:bit to randomly choose whether to display "truth" or display "dare". We can use accomplish this by using `math->random(2)`.
|
||
|
|
|
||
|
|
```
|
||
|
|
basic.showLeds(`
|
||
|
|
. . # . .

|
`, 400)
|
||
|
|
input.onButtonPressed("A", () => {
|
||
|
|
let random = Math.random(2)
|
||
|
|
})
|
||
|
|
```
|
||
|
|
|
||
|
|
Now let's display the appropriate message for each scenario of `random`.
|
||
|
|
|
||
|
|
```
|
||
|
|
basic.showLeds(`

`, 400)
|
||
|
|
input.onButtonPressed("A", () => {
|
||
|
|
let random1 = Math.random(2)
|
||
|
|
if (random1 == 0) {
|
||
|
|
basic.showString("TRUTH", 150)
|
||
|
|
} else {
|
||
|
|
basic.showString("DARE", 150)
|
||
|
|
}
|
||
|
|
})
|
||
|
|
```
|
||
|
|
|
||
|
|
* Run your program: Press button A!
|
||
|
|
|
||
|
|
Notice how the arrow didn't display again after pressing button `A`. Let's add a line of code that displays the arrow again.
