Create an arrow that randomly points to a player.
Before we get started
Complete the following guided tutorial, your code should look like this:
input.onGesture(Gesture.Shake, () => {
let randomArrow = Math.randomRange(0, 4)
if (randomArrow == 3) {
basic.showLeds(`
. . # . .
. # # # .
# # # # #
. . # . .
. . # . .
`)
}
if (randomArrow == 2) {
basic.showLeds(`
. . # . .
. . # . .
# # # # #
. # # # .
. . # . .
`)
}
if (randomArrow == 1) {
basic.showLeds(`
. . # . .
. # # . .
# # # # #
. # # . .
. . # . .
`)
}
})
Challenge 1
Modify the random number generator so that it can include new arrows we will create in the next challenge.
input.onGesture(Gesture.Shake, () => {
let randomArrow = Math.randomRange(0, 8)
if (randomArrow == 3) {
basic.showLeds(`
. . # . .
. # # # .
# # # # #
. . # . .
. . # . .
`)
}
if (randomArrow == 2) {
basic.showLeds(`
. . # . .
. . # . .
# # # # #
. # # # .
. . # . .
`)
}
if (randomArrow == 1) {
basic.showLeds(`
. . # . .
. # # . .
# # # # #
. # # . .
. . # . .
`)
}
})
- Do not run the code yet because it will not work until you have conditions for every random number.
Challenge 2
Let's add more arrows that point diagonally.
input.onGesture(Gesture.Shake, () => {
let randomArrow = Math.randomRange(0, 8)
if (randomArrow == 7) {
basic.showLeds(`
. . # . .
. # # # .
# # # # #
. . # . .
. . # . .
`)
}
if (randomArrow == 6) {
basic.showLeds(`
. . # . .
. . # . .
# # # # #
. # # # .
. . # . .
`)
}
if (randomArrow == 5) {
basic.showLeds(`
. . # . .
. # # . .
# # # # #
. # # . .
. . # . .
`)
}
if (randomArrow == 4) {
basic.showLeds(`
. . # . .
. . . # .
# # # # #
. . . # .
. . # . .
`)
}
if (randomArrow == 3) {
basic.showLeds(`
# # # # #
# # # # .
# # # # .
# . . # .
. . . . #
`)
}
if (randomArrow == 2) {
basic.showLeds(`
# # # # #
# # # # #
. . # # #
. # . # #
# . . . #
`)
}
if (randomArrow == 1) {
basic.showLeds(`
# . . . #
# # . # .
# # # . .
# # # # .
# # # # #
`)
}
})
- Run your code to see if it works as expected
Challenge 3
Add some other arrows if there are more than 8 players.
