Accelerometer
Last updated: 2025-02-24 17:10:36
startAccelerometer
This API is used via wx.startAccelerometer(Object object).
Note:
Depending on the performance of the device, as well as the current CPU and memory usage, there may be some discrepancies between the set
interval and the actual execution frequency of the wx.onAccelerometerChange callback function.Feature Description: Starts monitoring acceleration data.
Parameter and Description: Object.
Attribute | Type | Default value | Required | Description |
interval | string | normal | No | Execution frequency of the callback function for monitoring acceleration data |
success | function | - | No | Callback Function of Successful Interface Call |
fail | function | - | No | Callback Function of Failing Interface Call |
complete | function | - | No | Callback function executed upon the completion of the interface invocation (both successful and unsuccessful invocations) |
Valid values of object.interval
Value | Description |
game | Suitable for updating the callback frequency of the game, approximately every 20 ms. |
ui | Suitable for updating the callback frequency of the UI, approximately every 60 ms. |
normal | Regular callback frequency, approximately every 200 ms. |
Sample Code
wx.startAccelerometer({interval: 'game'})
stopAccelerometer
This API is used via wx.stopAccelerometer(Object object).
Feature Description: Stops monitoring acceleration data.
Parameter and Description: Object.
Attribute | Type | Default value | Required | Description |
success | function | - | No | Callback Function of Successful Interface Call |
fail | function | - | No | Callback Function of Failing Interface Call |
complete | function | - | No | Callback function executed upon the completion of the interface invocation (both successful and unsuccessful invocations) |
Sample Code
wx.stopAccelerometer()
onAccelerometerChange
This API is used via wx.onAccelerometerChange(function listener).
Feature Description: Monitor acceleration data events. The frequency depends on the interval parameter of wx.startAccelerometer(). The monitoring can be stopped using wx.stopAccelerometer().
Parameter and Description: Function callback.
The callback function for acceleration data events:
Attribute | Type | Description |
x | number | X-axis |
y | number | Y-axis |
z | number | Z-axis |
Sample Code
wx.onAccelerometerChange(function (res) {console.log(res.x)console.log(res.y)console.log(res.z)})
offAccelerometerChange
This API is used via wx.offAccelerometerChange(function listener).
Feature Description:
Parameters and Description: function listener, the listening function passed into onAccelerometerChange. If this parameter is not provided, all listening functions will be removed.
Sample Code
const listener = function (res) { console.log(res) }wx.onAccelerometerChange(listener)wx.offAccelerometerChange(listener) // The same function object as the listener must be passed in.
