Accelerometer Class¶
Description¶
Accelerometer调用了系统提供的加速度计,输出 AccelerometerResult 。
当不再需要该设备时,可以调用close对其进行关闭。close之后不应继续使用。
不建议同时打开多次加速度计,可能会无法使用或精度下降。
Constructor¶
- C
void easyar_Accelerometer__ctor(easyar_Accelerometer * * Return)
- C++17
Accelerometer()
- C++03(Deprecated)
Accelerometer()
- Java
public Accelerometer()
- Kotlin
constructor()
- Objective-C
+ (easyar_Accelerometer *) create
- Swift
public convenience init()
- C#
public Accelerometer()
isAvailable¶
检查是否可用。只在Android或iOS上且硬件支持时返回true。其他操作系统暂不支持。
- C
bool easyar_Accelerometer_isAvailable(easyar_Accelerometer * This)
- C++17
bool isAvailable()
- C++03(Deprecated)
bool isAvailable()
- Java

- Kotlin
fun isAvailable(): Boolean
- Objective-C
- (bool)isAvailable
- Swift
public func isAvailable() -> Bool
- C#
public virtual bool isAvailable()
open¶
打开设备。采样周期由内部实现所确定。如果打开失败,返回false。
- C
bool easyar_Accelerometer_open(easyar_Accelerometer * This)
- C++17
bool open()
- C++03(Deprecated)
bool open()
- Java

fun open(): Boolean
- Objective-C
- (bool)open
- Swift
public func `open`() -> Bool
- C#
public virtual bool open()
openWithSamplingPeriod¶
以特定采样周期打开设备。采样周期会受到硬件限制而可能无法达到指定值。如果打开失败,返回false。
- C
bool easyar_Accelerometer_openWithSamplingPeriod(easyar_Accelerometer * This, int samplingPeriodMilliseconds)
- C++17
bool openWithSamplingPeriod(int samplingPeriodMilliseconds)
- C++03(Deprecated)
bool openWithSamplingPeriod(int samplingPeriodMilliseconds)
- Java
public boolean openWithSamplingPeriod(int samplingPeriodMilliseconds)
- Kotlin
fun openWithSamplingPeriod(samplingPeriodMilliseconds: Int): Boolean
- Objective-C
- (bool)openWithSamplingPeriod:(int)samplingPeriodMilliseconds
- Swift
public func openWithSamplingPeriod(_ samplingPeriodMilliseconds: Int32) -> Bool
- C#
public virtual bool openWithSamplingPeriod(int samplingPeriodMilliseconds)
close¶
关闭设备。close之后不应继续使用。

fun getCurrentResult(): AccelerometerResult?
- Objective-C
- (easyar_AccelerometerResult *)getCurrentResult
- Swift
public func getCurrentResult() -> AccelerometerResult?
- C#
public virtual Optional<AccelerometerResult> getCurrentResult()
