Welcome! This guided tutorial will teach how to program a script that randomly points to a player. Let's get started!
Let's begin by adding an on shake condition to know when the @boardname@ is shaken.
input.onGesture(Gesture.Shake, () => {
})
Now let's randomly generate a number from 0 to 3 so that we can randomly display an arrow in a given direction.
input.onGesture(Gesture.Shake, () => {
let randomArrow = Math.random(4)
if (randomArrow == 3) {
basic.showLeds(`
. . # . .
. # # # .
# # # # #
. . # . .
. . # . .
`)
}
})
Now let's handle each of the cases by displaying the appropriate arrow. (Let's display an up arrow if random arrow is 0.
input.onGesture(Gesture.Shake, () => {
let randomArrow = Math.random(4)
if (randomArrow == 3) {
basic.showLeds(`
. . # . .
. # # # .
# # # # #
. . # . .
. . # . .
`)
}
if (randomArrow == 2) {
basic.showLeds(`
. . # . .
. . # . .
# # # # #
. # # # .
. . # . .
`)
}
})
Now let's handle the rest of the cases for random arrow.
input.onGesture(Gesture.Shake, () => {
let randomArrow = Math.random(4)
if (randomArrow == 3) {
basic.showLeds(`
. . # . .
. # # # .
# # # # #
. . # . .
. . # . .
`)
}
if (randomArrow == 2) {
basic.showLeds(`
. . # . .
. . # . .
# # # # #
. # # # .
. . # . .
`)
}
if (randomArrow == 1) {
basic.showLeds(`
. . # . .
. # # . .
# # # # #
. # # . .
. . # . .
`)
}
})
