WVR_GetInputDeviceState¶
-
WVR_EXPORT bool WVR_GetInputDeviceState(WVR_DeviceType type, uint32_t inputType, uint32_t * buttons, uint32_t * touches, WVR_AnalogState_t * analogArray, uint32_t analogArrayCount) Function to get the WVR_InputType data. InputType is a bitmask that represents the combined input types for WVR_InputType.
- Return
- False when any of the parameter WVR_InputType fails to get data. For example, if inputType is a combination of WVR_InputType_Button and WVR_InputType_Analog but the WVR_InputType_Button data was not retrieved, the API will return false.
- Version
- API Level 1
- Parameters
type: Indicates what device to get the InputDeviceState. (refer to WVR_DeviceType)inputType: Bitmask to represent the combined input type for WVR_InputType. Developers can get a single or combined input status.buttons: Bitmask to represent the button state. Each bit corresponds to WVR_InputId.touches: Bitmast to represent the touches state. Each bit corresponds to WVR_InputId.analogArray: An array of WVR_AnalogState_t to represent all analog data. (refer to WVR_AnalogState)analogArrayCount: Developer should the the array count from the WVR_GetInputTypeCount API.
How to use¶
This sample shows how to get the button state.
#include <wvr/wvr_device.h>
// Must initialize the VR runtime once before related API.
WVR_InitError eError = WVR_InitError_None;
eError = WVR_Init(WVR_AppType_VRContent);
if (eError != WVR_InitError_None) {
LOGE("Unable to initialize VR runtime: %s", WVR_GetInitErrorString(eError));
return;
}
uint32_t inputType = WVR_InputType_Button;
uint32_t buttons = 0, touches = 0;
if (WVR_GetInputDeviceState(WVR_DeviceType_Controller_Right, inputType, &buttons, &touches, nullptr, 0)) {
for (int i = 0; i < WVR_InputId_Max; i++) {
int input = 1 << i;
if ((buttons & input) == input) {
printf("WVR_DeviceType_Controller_Right InputId_%d is pressed.\n", i);
}
}
}
This sample shows how to get the axis state.
#include <wvr/wvr_device.h>
// Must initialize the VR runtime once before related API.
WVR_InitError eError = WVR_InitError_None;
eError = WVR_Init(WVR_AppType_VRContent);
if (eError != WVR_InitError_None) {
LOGE("Unable to initialize VR runtime: %s", WVR_GetInitErrorString(eError));
return;
}
uint32_t inputType = WVR_InputType_Touch | WVR_InputType_Analog;
uint32_t buttons = 0, touches = 0;
uint32_t analogCount = WVR_GetInputTypeCount(WVR_DeviceType_Controller_Left, WVR_InputType_Analog);
if (analogCount < 0) retrun;
WVR_AnalogState_t analogState[analogCount];
if (WVR_GetInputDeviceState(WVR_DeviceType_Controller_Left, inputType, &buttons, &touches, analogState, analogCount)) {
for (int i = 0; i < analogCount; i++) {
int input = 1 << analogState[i].id;
if ((touches & input) == input) {
printf("WVR_DeviceType_Controller_Left InputId_%d analog data(x, y) = (%f, %f)\n",
analogState[i].id, analogState[i].axis.x, analogState[i].axis.y);
}
}
}
When the variable (bit) inside the variable (touches) taken from WVR_GetInputDeviceState is valid, then the corresponding WVR_AnalogState_t is useful.
