Remarks

Touch layouts that are presented to the player during game streaming use pre-defined layouts that are uploaded to Microsoft as part of a touch adaptation bundle. XGameStreamingGetTouchBundleVersion enables the game to make runtime decisions based on the set of touch controls that are being utilized on a particular client. Some examples of where this might be utilized:

To remove an element from the HUD if the player is using touch and the element is available via the touch overlay controls.
To decide which graphical hints to display in the game based on the touch layouts that will be displayed.

The version will be unique per version that is uploaded to the service. Every update will require a new version number.

The versionName can be used to provide a semantic version (e.g., this is a set of layouts that support DLC2) as opposed to locking to a specific version number. For example, if version numbers are assigned automatically by your build system, it may be difficult for game code to know the exact version number of the touch adaptation bundles that will appear at runtime. In order to allow the code to detect the presence of a bundle without having to know its exact version, it may choose to use a version name instead of doing comparisons based upon a version number.

Example

void GameStreamingClientManager::GetClientTouchBundleVersion(XGameStreamingClientId client)
{
    // Get the touch bundle version and initialize the touch HUD based on the 
    // semantic version name that was returned
    
    size_t versionNameSize = XGameStreamingGetTouchBundleVersionNameSize(clientId);

    XVersion version{};
    std::vector<char> versionName(versionNameSize, 0);
    XGameStreamingGetTouchBundleVersion(clientId, &version, versionNameSize, &versionName[0]);

    InitializeTouchHUD(versionName);

    if (strcmp("DLC2", versionName.data()) == 0)
    {
        // we have our DLC2 controls, switch to the HUD layout that works best with those overlay controls.
        InitializeHUDForDLC2TouchControls();
    }
}
