/**
|
|
* The base class of any per platform settings. The pattern for using these is as follows.
|
|
*
|
|
* Step 1) Subclass UPlatformSettings, UMyPerPlatformSettings : public UPlatformSettings.
|
|
*
|
|
* Step 2) For your system should already have a UDeveloperSettings that you created so that
|
|
* users can customize other properties for your system in the project. On that class
|
|
* you need to create a property of type FPerPlatformSettings, e.g.
|
|
* UPROPERTY(EditAnywhere, Category=Platform)
|
|
* FPerPlatformSettings PlatformOptions
|
|
*
|
|
* Step 3) In your UDeveloperSettings subclasses construct, there should be a line like this,
|
|
* PlatformOptions.Settings.Initialize(UMyPerPlatformSettings::StaticClass());
|
|
* This will actually ensure that you initialize the settings exposed in the editor to whatever
|
|
* the current platform configuration is for them.
|
|
*
|
|
* Step 4) Nothing else needed. In your system code, you will just call
|
|
* UMyPerPlatformSettings* MySettings = UPlatformSettingsManager::Get().GetSettingsForPlatform<UMyPerPlatformSettings>()
|
|
* that will get you the current settings for the active platform, or the simulated platform in the editor.
