Detailed Description

Game and content update handler functions.

The updater is an abstraction of the engine its own package manager. Not all packages the engine offers are related to the game you're currently running. Therefore we offer our own API within Nuclide to deal with game updates.

You want to call Updates_Init() once, after which Updates_GetUpdaterStatus() should be queried to determine when the Updater is ready. That is not necessary, but it might be helpful to throw up a loading screen while that is returning UPDATER_PENDING.

Once Updates_GetUpdaterStatus() reports UPDATER_INITIALIZED, you can expect the loading to be fully done.

The function Updates_GetPackageCount() will report the total amount of update packages available for the game. These are not 'new' updates, they contain every package associated with the game that can and should be installed and kept updated.

Use Updates_GetInfo() to retrieve metadata about individual packages.

UPDATER_PENDING	Nuclide's updater is pending. May change to UNAVAILABLE or INITIALIZED.
UPDATER_INITIALIZED	Nuclide's updater is initialized and may have entries. Use Updates_GetPackageCount() to query how many.

enum updateState_t

Return values from passing UPDATE_STATE to Updates_GetInfo()

Enumerator
UPDATESTATE_NONE	Update is not installed, or unavailable.
UPDATESTATE_DISABLED	Update is installed, but disabled.
UPDATESTATE_ENABLED	Update is installed and enabled.
UPDATESTATE_CORRUPT	Update on disk is corrupted.
UPDATESTATE_PENDING	Update is pending a change. Usually when we're downloading it.
