Block Playback

Sample Description

This sample program demonstrates how to branch to a jingle sound (that is a block Cue) during playback.

The block Cue is created in CRI Atom Craft.
For details, refer to the following: Block playback

In the program,
specify the first block index to the player with the criAtomExPlayer_SetFirstBlockIndex function,
and then specify the next block indexes for the playback ID with the criAtomExPlayback_SetNextBlockIndex.

The following code demonstrates how to play and control a block Cue that branches during playback.

/* Create the player */
player = criAtomExPlayer_Create(NULL, NULL, 0);
 
/* Set the block Cue */
player = criAtomExPlayer_SetCueName(acb, "block");
 
/* Select the first block */
criAtomExPlayer_SetFirstBlockIndex(app_obj->player, 0);
 
/* Start playback */
CriAtomExPlaybackId playback_id;
playback_id = criAtomExPlayer_Start(player);
    :
/* Specify the next block */
if (status_of_something) {
    criAtomExPlayback_SetNextBlockIndex(playback_id, 1);
} else {
    criAtomExPlayback_SetNextBlockIndex(playback_id, 2);
}

You can also use the criAtomExPlayer_SetBlockTransitionCallback function, as shown in the code below, to receive a callback when the block transitions.

void main()
{
    /* Register transition callback */
    criAtomExPlayer_SetBlockTransitionCallback(
        app_obj->player, &user_transition_callback_func, app_obj);
}
 
void user_transition_callback_func(
    void *obj, CriAtomExPlaybackId id, CriAtomExBlockIndex index)
{
    printf("PlaybackId:%d, BlockIndex:%d\n", id, index);
}
