|---|---|---|---|---|
| success | function | Whether | The interface calls a successful callback function | |
| fail | function | Whether | The interface calls the failed callback function | |
| complete | function | Whether | Callback function at end of interface call (call succeeds, fails are executed) |
The base library 2.3.0 starts to support, and the lower version needs to be compatible.
Start listening for changes in the orientation of the device.
| Property | Type | The default | Required | Description |
|---|---|---|---|---|
| interval | string | normal | Whether | The frequency with which the callback function performs to listen for changes in the orientation of the device |
| success | function | Whether | The interface calls a successful callback function | |
| fail | function | Whether | The interface calls the failed callback function | |

The legal value of object.interval
| Value | Description | The lowest version |
|---|---|---|
| game | Callback frequency for updating games, around 20ms/time | |
| Ui | Callback frequency for updating the UI, around 60ms/time | |
| normal | Normal callback frequency, around 200ms/time |
The base library 2.3.0 starts to support, and the lower version needs to be compatible.
Listen for device orientation change events. T he frequency is based on the interval parameter of wx.startDeviceMotionListening(). You can use wx.stopDeviceMotionListening() to stop listening.
The callback function for the device orientation change event
| Property | Type | Description |
|---|---|---|
| alpha | number | When the phone coordinates X/Y and Earth X/Y meet, the angle that rotates around the Z axis is alpha, with a range value of .0, 2 x PI. Turn counterclockwise to positive. |
| Beta | number | When the phone coordinates Y/Z and Earth Y/Z meet, the angle that rotates around the X axis is beta. T he range value is -1-PI, PI. T he top rotates positively toward the earth's surface. It is also possible to move towards the user as positive. |
| gamma | number | When the phone X/Z and Earth X/Z meet, the angle that rotates around the Y axis is gamma. T he range value is -1 x PI/2, PI/2). The right side turns positive towards the earth's surface. |
