Managing of a user-created game object to provide secure and predictable game performance
The present technology receives raw assets of user-generated content at a platform server. The platform server can utilize techniques to recognize reused assets to avoid storing duplicate data. Additionally, the present technology can utilize a validation scheme by which portions of user content that include executable code are only permitted to be uploaded to the platform server when these portions of the user content are recognized and are already known to be safe. Additionally, the present technology can be configured to modify the raw assets of the content to be compatible with the latest updates to the platform and to the distribution platforms in which the user-generated content will be executed.
