useGamepad
Provides reactive bindings for the Gamepad API.
Demo
Usage
Due to how the Gamepad API works, you must interact with the page using the gamepad before it will be detected.
<script setup>
import { computed } from 'vue'
import { useGamepad } from '@vueuse/core'
const { isSupported, gamepads } = useGamepad()
const gamepad = computed(() => gamepads.find(g => g.mapping === 'standard'))
</script>
<template>
<span>
{{ gamepad.id }}
</span>
</template>
Gamepad Updates
Currently the Gamepad API does not have event support to update the state of the gamepad. To update the gamepad state, requestAnimationFrame
is used to poll for gamepad changes. You can control this polling by using the pause
and resume
functions provided by useGamepad
import { useGamepad } from '@vueuse/core'
const { pause, resume, gamepads } = useGamepad()
pause()
// gamepads object will not update
resume()
// gamepads object will update on user input
Gamepad Connect & Disconnect Events
The onConnected
and onDisconnected
events will trigger when a gamepad is connected or disconnected.
const { gamepads, onConnected, onDisconnected } = useGamepad()
onConnected((index) => {
console.log(`${gamepads.value[index].id} connected`)
})
onDisconnected((index) => {
console.log(`${index} disconnected`)
})
Vibration
The Gamepad Haptics API is sparse, so check the compatibility table before using.
import { computed } from 'vue'
const supportsVibration = computed(() => gamepad.hapticActuators.length > 0)
function vibrate() {
if (supportsVibration.value) {
const actuator = gamepad.hapticActuators[0]
actuator.playEffect('dual-rumble', {
startDelay: 0,
duration: 1000,
weakMagnitude: 1,
strongMagnitude: 1,
})
}
}
Mappings
To make the Gamepad API easier to use, we provide mappings to map a controller to a controllers button layout.
Xbox360 Controller
<script setup>
import { mapGamepadToXbox360Controller } from '@vueuse/core'
const controller = mapGamepadToXbox360Controller(gamepad)
</script>
<template>
<span>{{ controller.buttons.a.pressed }}</span>
<span>{{ controller.buttons.b.pressed }}</span>
<span>{{ controller.buttons.x.pressed }}</span>
<span>{{ controller.buttons.y.pressed }}</span>
</template>
Currently there are only mappings for the Xbox 360 controller. If you have controller you want to add mappings for, feel free to open a PR for more controller mappings!
