This section of the manual covers the different platform specific Preferences that need to be set up before you can compile your games to certain targets. These generally only need set up once to start with (although future updates to the runtimes may require you to change certain things, but these will be mentioned in the Release Notes) and are used to point to any SDKs that are required and set basic Compiling options for how you want GameMaker to compile your game projects for any given platform. Note that the platforms available will depend on the Licence that you have and not all of them may be available.
Below is a list of all the available target platforms for standard licences:
Note that apart from setting up these preferences, you will also need to set up the devices that some of these platforms target, otherwise you may not be able to compile nor test your projects. See the section on Compiling and the section on the Device Manager for more information.
The manual does not show the various Console preferences (Xbox, PlayStation and Nintendo Switch) due to the different legal restrictions maintained by the different companies. If you have a Console Licence, then you can get this information from the YoYo Games Helpdesk, but you must first contact YoYo Games with your console ID email and request permission to view the different sections.
