User Generated Content (UGC)

This section shows the functions associated with the Steam API specifically for user generated content (UGC).

This section is for those users that have been given access to the Steam API for publishing your game to that platform and that want to use the possibilities that the Steam Workshop and Community gives you for adding and generating user content in your projects. Some of the functions in this page require the Steam App ID for your project as well as a User ID for the person playing the game or their user name, which can be found using the following functions:

Before using any of the built in functions for the Steam UGC API you need to have set up your game correctly from the Steam dashboard and you should have read through the required documentation found here: Sharing User Generated Content (note that you need to have your game accepted for the Steam network and have access to the developer areas of the Steam API documentation). All subscribed UGC items will be downloaded by the Steam client automatically, and you should have code in the Steam Asynchronous Event to catch this and store the ID of the UGC that has been downloaded for use in the other UGC functions.

The normal workflow for getting UGC into your game would be as follows:

  • The user would subscribe to an item (either from your game using steam_ugc_subscribe_item() or from the client/browser.

  • Your game would "listen" for new subscriptions with the appropriate code in the Steam Async Event.

  • When you get a subscription async event, you would then check if the item is installed (ie: downloaded) with steam_ugc_get_item_install_info().

  • If the item is not installed, you'll need a check using steam_ugc_get_item_update_info() to track the download progress.

Creating And Editing Content

The following functions are essentially "wrapper" functions for those supplied in the Steam API for creating and uploading content to their servers. As such, we recommend that you read over the linked Steam documentation before using them to gain a greater understanding of how they work: Creating And Uploading Content.

Consuming Content

Once your user content has been created and the workshop has it available for download, people can subscribe to it through the Steam App or through the Web portal. However GameMaker: Studio also includes the following functions to use the Steam API for creating and canceling subscriptions as well as for getting information about what the user is subscribed to currently:

Querying Content

There are also a large number of functions available to query the Steam API about the UGC items available:

You can get a preview image of any UGC item from the workshop by using the function steam_ugc_send_query() to get the preview file handle of the image, and then calling the following function:
