Action2/Only Callback Failure
Introduction
The features
- Sound Effects
- Signals
have no regular Action2 to assign graphics. However, Action2 is still needed to make callbacks fail.
Syntax
<Sprite-number> * <Length> 01 <feature> 01 00 <Sprite-number> * <Length> 02 <feature> <set-id> 01 00 00 00
This syntax consists of both an Action1 and the actual Action2. See the detailed description below.
| Element | Size | Description |
|---|---|---|
| <Sprite-number> | dec | A sequential sprite number |
| <length> | dec | The total number of bytes used in this action |
| <set-id> | B | What set-ID this action2 defines |
Description
The syntax to use is the syntax of the regular Action2 referencing Action1 spritesets. However:
- Every Action2 must reference at least one spriteset, so we must also define one via Action1.
- Every Action1 must define at least one spriteset, but spritesets may contain zero sprites.
Above syntax specifies two pseudo sprites. First an Action1 defining 1 spriteset with 0 sprites, then the Action2 referencing only that single spriteset.
Sprite-number
This is just the number you are at.
Length
Count the number of bytes in this action.
set-id
This defines the ID of the current action 2. This ID will later be referred to by action 3, or a variational/random action 2.
You can reuse action 2 IDs, and there's no restriction on the order in which they are defined.
