WVR_GetDefaultControllerRole

WVR_EXPORT WVR_DeviceType WVR_GetDefaultControllerRole()

Function to get the default controller role that determines the role of the first controller that connects. When the controller role changes, the server will send an WVR_EventType_DeviceRoleChanged event to notify all applications. During this time, applications need to check the controller roles again with this API(WVR_GetDefaultControllerRole).

Return

The type of controller role, WVRDeviceType_Controller_Right or WVRDeviceType_Controller_Left. (refer to WVR_DeviceType)

Version

API Level 1

How to use

Here is an example for the function:

#include <wvr/wvr_types.h>
#include <wvr/wvr_events.h>

// Catch event that is sent from the VR server, device service, or settings app
WVR_Event_t event;
while (WVR_PollEventQueue(&event)) {
    switch (event.common.type) {
        …
        case WVR_EventType_DeviceRoleChanged:
            //Perform an action when the controller role changes
            WVR_DeviceType role = WVR_GetDefaultControllerRole(); // get default controller role
            if ( role == WVR_DeviceType_Controller_Right ) {
                // first controller is right hand
                …
            } else if ( role == WVR_DeviceType_Controller_Left ) {
                // first controller is left hand
                …
            }

            if (WVR_IsDeviceConnected(role)) {
                WVR_PoseState_t pose;
                WVR_GetPoseState(role, WVR_PoseOriginModel_OriginOnHead, 0, &pose);
            }
        break;
        …
    }
