This function only exists in Sonic Origins.

Description

Sends the given callback to communicate to Hedgehog Engine 2.

For more information on NotifyCallback, including a list of usable callbacks, see this page.

Parameters

  • callback The index value of the callback.
  • param1, param2, param3 Parameters to use for the callback.

Return Value

Depends on the callback used.

Syntax

NotifyCallback(int32 callback, int32 param1, int32 param2, int32 param3);

Example

NotifyCallback(NOTIFY_STATS_CHARA_ACTION, 1, 0, 0);

Note

This is a macro, which is designed to make programming in RSDK easier. The underlying logic is: 

if (HasNotifyCallback())
    RSDKTable->NotifyCallback(callback, param1, param2, param3);
HasNotifyCallback() is a macro as well, with its underlying logic being RSDKTable->NotifyCallback != NULL. The underlying logic for either macro should NEVER be used as it's less safe than the macros. This note is here for anyone wishing to learn about the internals or hoping to develop a wrapper for another language that doesn't support macros.
