# dice roll challenges
|
|
|
|
Create a dice on the @boardname@.
|
|
|
|
## Before we get started
|
|
|
|
Complete the following [guided tutorial](/lessons/dice-roll/activity), your code should look like this:
|
|
|
|
```blocks
|
|
input.onGesture(Gesture.Shake, () => {
|
|
let roll = Math.random(6);
|
|
if (roll == 5) {
|
|
basic.showLeds(`
|
|
. # . # .
|
|
. . . . .
|
|
. # . # .
|
|
. . . . .
|
|
. # . # .`);
|
|
}
|
|
else if (roll == 4) {
|
|
basic.showLeds(`
|
|
. . . . .
|
|
. # . # .
|
|
. . # . .
|
|
. # . # .
|
|
. . . . .`);
|
|
}
|
|
else if (roll == 3) {
|
|
basic.showLeds(`
|
|
. . . . .
|
|
. # . # .
|
|
. . . . .
|
|
. # . # .
|
|
. . . . .`);
|
|
}
|
|
else if (roll == 2) {
|
|
basic.showLeds(`
|
|
# . . . .
|
|
. . . . .
|
|
. . # . .
|
|
. . . . .
|
|
. . . . #`);
|
|
}
|
|
else if (roll == 1) {
|
|
basic.showLeds(`
|
|
. . . . .
|
|
. # . . .
|
|
. . . . .
|
|
. . . # .
|
|
. . . . .`);
|
|
}
|
|
else {
|
|
basic.showLeds(`
|
|
. . . . .
|
|
. . . . .
|
|
. . # . .
|
|
. . . . .
|
|
. . . . .`);
|
|
}
|
|
});
|
|
```
|
|
|
|
## Challenge 1
|
|
|
|
Modify the line of code with `pick random` so that only number 1-4 can appear on the dice.
|
|
|
|
|
|
```blocks
|
|
input.onGesture(Gesture.Shake, () => {
|
|
let roll = Math.random(4);
|
|
if (roll == 5) {
|
|
basic.showLeds(`
|
|
. # . # .
|
|
. . . . .
|
|
. # . # .
|
|
. . . . .
|
|
. # . # .`);
|
|
}
|
|
else if (roll == 4) {
|
|
basic.showLeds(`
|
|
. . . . .
|
|
. # . # .
|
|
. . # . .
|
|
. # . # .
|
|
. . . . .`);
|
|
}
|
|
else if (roll == 3) {
|
|
basic.showLeds(`
|
|
. . . . .
|
|
. # . # .
|
|
. . . . .
|
|
. # . # .
|
|
. . . . .`);
|
|
}
|
|
else if (roll == 2) {
|
|
basic.showLeds(`
|
|
# . . . .
|
|
. . . . .
|
|
. . # . .
|
|
. . . . .
|
|
. . . . #`);
|
|
}
|
|
else if (roll == 1) {
|
|
basic.showLeds(`
|
|
. . . . .
|
|
. # . . .
|
|
. . . . .
|
|
. . . # .
|
|
. . . . .`);
|
|
}
|
|
else {
|
|
basic.showLeds(`
|
|
. . . . .
|
|
. . . . .
|
|
. . # . .
|
|
. . . . .
|
|
. . . . .`);
|
|
}
|
|
});
|
|
```
|
|
|
|
## Challenge 2
|
|
|
|
Let's make a trick dice! Modify the line of code with `pick random` so that only numbers 3-6 can appear on the dice. Also note that we need to ensure `roll = 0` when only 1 dot is shown on the @boardname@.
|
|
|
|
```blocks
|
|
input.onGesture(Gesture.Shake, () => {
|
|
let roll = Math.random(4) + 2;
|
|
if (roll == 5) {
|
|
basic.showLeds(`
|
|
. # . # .
|
|
. . . . .
|
|
. # . # .
|
|
. . . . .
|
|
. # . # .`);
|
|
}
|
|
else if (roll == 4) {
|
|
basic.showLeds(`
|
|
. . . . .
|
|
. # . # .
|
|
. . # . .
|
|
. # . # .
|
|
. . . . .`);
|
|
}
|
|
else if (roll == 3) {
|
|
basic.showLeds(`
|
|
. . . . .
|
|
. # . # .
|
|
. . . . .
|
|
. # . # .
|
|
. . . . .`);
|
|
}
|
|
else if (roll == 2) {
|
|
basic.showLeds(`
|
|
# . . . .
|
|
. . . . .
|
|
. . # . .
|
|
. . . . .
|
|
. . . . #`);
|
|
}
|
|
else if (roll == 1) {
|
|
basic.showLeds(`
|
|
. . . . .
|
|
. # . . .
|
|
. . . . .
|
|
. . . # .
|
|
. . . . .`);
|
|
}
|
|
else {
|
|
basic.showLeds(`
|
|
. . . . .
|
|
. . . . .
|
|
. . # . .
|
|
. . . . .
|
|
. . . . .`);
|
|
}
|
|
});
|
|
```
|
|
|
|
## Challenge 3
|
|
|
|
Add a couple more conditions so that the @boardname@ randomly chooses a number between 1 and 8.
