# truth or dare activity a multi-player game that forces each player to reveal a secret or something funny. #docs Begin by plotting an "up-arrow" image, which will point to someone. ``` basic.showLeds(` . . # . . . # # # . # # # # # . . # . . . . # . . `, 400) ``` * 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(Button.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(Button.A, () => { let random = Math.random(2) }) ``` Now let's display the appropriate message for each scenario of `random`. ``` basic.showLeds(` . . # . . . # # # . # # # # # . . # . . . . # . . `, 400) input.onButtonPressed(Button.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. ``` basic.showLeds(` . . # . . . # # # . # # # # # . . # . . . . # . . `, 400) input.onButtonPressed(Button.A, () => { let random2 = Math.random(2) if (random2 == 0) { basic.showString("TRUTH", 150) } else { basic.showString("DARE", 150) } basic.showLeds(` . . # . . . # # # . # # # # # . . # . . . . # . . `, 400) }) ``` * Run your program: Press button A! ### ~avatar avatar Excellent, you're ready to continue with the [challenges](/lessons/truth-or-dare/challenges)! ### ~
