Message Hooks

This is a dependency mod. It provides hooks inside Message_Update and Message_DrawMain for use in other mods.

Features

Events

This mod provides events with following signatures:

mh_on_Message_Update_<MSGMODE>(PlayState* play)
mh_on_Message_DrawMain_<MSGMODE>(PlayState* play, Gfx** gfxP)

where <MSGMODE> is the name of a MessageMode value without the MSGMODE_ prefix.

Each of these events is called only when play->msgCtx->msgMode matches it's <MSGMODE>.

For example, if you want to hook into MSGMODE_TEXT_DONE in Message_Update's switch clause, you should make a callback to mh_on_Message_Update_TEXT_DONE.

There are also universal events called no matter the play->msgCtx->msgMode's value. Their syntax is the same but they don't have a suffix:

mh_on_Message_Update(PlayState* play)
mh_on_Message_DrawMain(PlayState* play, Gfx** gfxP)

However, they should be avoided unless necessary.

Early return

The mod provides an import for use inside the callbacks. It sets the flag that makes the vanilla function return early before it dives into it's switch clause:

void mh_set_return_flag(void);

Usage example

RECOMP_IMPORT("mm_recomp_message_hooks", void mh_set_return_flag(void));

RECOMP_CALLBACK("mm_recomp_message_hooks", mh_on_Message_Update_TEXT_DONE) void on_Message_Update(PlayState* play) {
    if (...) {
        ...
        mh_set_return_flag();
    }
}

RECOMP_CALLBACK("mm_recomp_message_hooks", mh_on_Message_DrawMain_TEXT_CLOSING) void on_Message_DrawMain(PlayState* play, Gfx** gfxP) {
    ...
}
