WVR_GetInputMappingTable

WVR_EXPORT uint32_t WVR_GetInputMappingTable(WVR_DeviceType type, WVR_InputMappingPair * table, uint32_t size)

Get the entire input mapping table.

Return

Retrieves the mapping table from the input id of the hardware device to map the software input events needed by an app.

Version

API Level 3

Parameters

• type: Indicates what device type. (refer to WVR_DeviceType).
• table: Outputs the entire input mapping table.
• size: The allocated buffer size for the table.

How to use

Here is an example for the function:

#include <wvr/wvr_device.h>

WVR_InputAttribute array[] = {
    {WVR_InputId_Alias1_Menu, WVR_InputType_Button, WVR_AnalogType_None},
    {WVR_InputId_Alias1_Grip, WVR_InputType_Button, WVR_AnalogType_None},
    {WVR_InputId_Alias1_Touchpad, WVR_InputType_Button | WVR_InputType_Touch | WVR_InputType_Analog, WVR_AnalogType_2D},
    {WVR_InputId_Alias1_Trigger, WVR_InputType_Button | WVR_InputType_Touch | WVR_InputType_Analog, WVR_AnalogType_1D},
};

WVR_SetInputRequest(WVR_DeviceType_Controller_Right, array, sizeof(array) / sizeof(*array));

auto size = WVR_GetInputMappingTable(WVR_DeviceType_Controller_Right, nullptr, 0);
WVR_InputMappingPair elements[size];
WVR_GetInputMappingTable(WVR_DeviceType_Controller_Right, elements, size);
for (int i = 0; i < size; i++) {
    auto element = elements[i];
    std::cout << "request InputId_" << element.source.id << ", capability is " <<
              element.source.capability << ", axis type is" << element.source.axis_type << "." << std::endl;
    std::cout << "Mapped to InputId_" << element.destination.id << ", capability is " <<
              element.destination.capability << ", axis type is" << element.destination.axis_type << "." << std::endl;
}
