提供了 Gamepad API 的响应式绑定。

示例

源码

此设备不支持游戏手柄。似乎你的设备不支持游戏手柄 API。查看这里以查看支持游戏手柄的设备列表。

使用方法

由于 Gamepad API 的工作方式，你必须使用游戏手柄与页面进行交互，然后才能检测到它。

vue

<script setup>
import { useGamepad } from '@vueuse/core'
import { computed } from 'vue'

const { isSupported, gamepads } = useGamepad()
const gamepad = computed(() => gamepads.value.find(g => g.mapping === 'standard'))
</script>

<template>
  <span>
    {{ gamepad.id }}
  </span>
</template>

游戏手柄更新

目前，Gamepad API 没有事件支持来更新游戏手柄的状态。为了更新游戏手柄的状态，使用 requestAnimationFrame 来轮询游戏手柄的变化。你可以通过使用 useGamepad 提供的 pause 和 resume 函数来控制此轮询。

import { useGamepad } from '@vueuse/core'

const { pause, resume, gamepads } = useGamepad()

pause()

// 游戏手柄对象不会更新

resume()

// 游戏手柄对象将在用户输入时更新

游戏手柄连接和断开事件

当游戏手柄连接或断开连接时，onConnected 和 onDisconnected 事件将触发。

const { gamepads, onConnected, onDisconnected } = useGamepad()

onConnected((index) => {
  console.log(`${gamepads.value[index].id} connected`)
})

onDisconnected((index) => {
  console.log(`${index} disconnected`)
})

振动

游戏手柄触觉 API 的支持不完整，请在使用之前检查兼容性表。

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,
    })
  }
}

映射

为了使 Gamepad API 更易于使用，我们提供了映射来将控制器映射到控制器的按钮布局。

Xbox360 控制器

vue

<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>

目前只有 Xbox 360 控制器的映射。如果你有要添加映射的控制器，请随时为更多控制器映射打开 PR！
