NotifyCallback

NotifyCallback is a function in Sonic Origins that handles communicating between RSDKv5U and Hedgehog Engine 2.

Usage

Set game.callbackParam0, game.callbackParam1, and game.callbackParam2 to the needed parameters (unused parameters do not need to be set), then call EngineCallback() with Callback set to the appropriate callback ID.

Note

The names of each callback are not defined by the engine itself. Instead, Sonic Team elected to define them and their corresponding IDs as global variables in Sonic CD's GameConfig.

Call CallNativeFunction2() or CallNativeFunction4() (depending on the amount of parameters needed) with callback set to NotifyCallback and param1 set to the appropriate callback ID. Set param2, param3, and param4 to the needed parameters. Unused parameters should be set to 0.

Note

The names of each callback are not defined by the engine itself. Instead, Sonic Team elected to define them and their corresponding IDs as global variables in Sonic 1 and 2's GameConfigs.

Call NotifyCallback() with callback set to the appropriate callback ID and param1, param2, and param3 set to the needed parameters. Unused parameters should be set to NULL.
