# truth or dare activity A multi-player game that forces each player to reveal a secret or something funny. ### ~avatar avatar 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! ### ~avatar avatar Excellent, you're ready to continue with the [challenges](/lessons/truth-or-dare/challenges)! ### ~
