On Gesture

Start an event handler (part of the program that will run when something happens) This handler works when you do a gesture (like shaking the @boardname@).

input.onGesture(Gesture.Shake,() => {
})

Parameters

• gesture means the way you hold or move the @boardname@. This can be shake, logo up, logo down, screen up, screen down, tilt left, tilt right, free fall, 3g, or 6g.

Example: random number

This program shows a number from 2 to 9 when you shake the @boardname@.

input.onGesture(Gesture.Shake,() => {
    let x = Math.randomRange(2, 9)
    basic.showNumber(x)
})
