How to join paths?

What is the correct way to join paths in Urho3D? I’d like to write a config file to GetSubsystem<FileSystem>()->GetAppPreferencesDir()

Hi,

You have a lot of choices for joining paths… Here it is done in Samples.

github.com

urho3d/Urho3D/blob/a476f0c40114b92c2637145c24f50ccef6de5d3c/Source/Samples/Sample.inl#L61


    screenJoystickIndex_(M_MAX_UNSIGNED),
    screenJoystickSettingsIndex_(M_MAX_UNSIGNED),
    paused_(false)
{
}


void Sample::Setup()
{
    // Modify engine startup parameters
    engineParameters_[EP_WINDOW_TITLE] = GetTypeName();
    engineParameters_[EP_LOG_NAME]     = GetSubsystem<FileSystem>()->GetAppPreferencesDir("urho3d", "logs") + GetTypeName() + ".log";
    engineParameters_[EP_FULL_SCREEN]  = false;
    engineParameters_[EP_HEADLESS]     = false;
    engineParameters_[EP_SOUND]        = false;


    // Construct a search path to find the resource prefix with two entries:
    // The first entry is an empty path which will be substituted with program/bin directory -- this entry is for binary when it is still in build tree
    // The second and third entries are possible relative paths from the installed program/bin directory to the asset directory -- these entries are for binary when it is in the Urho3D SDK installation location
    if (!engineParameters_.Contains(EP_RESOURCE_PREFIX_PATHS))
        engineParameters_[EP_RESOURCE_PREFIX_PATHS] = ";../share/Resources;../share/Urho3D/Resources";
}
