<p class="inwebparagraph"><a id="SP1"></a><b>§1. Resource Usage. </b>We record whether pictures or sounds have been used before by storing
|
|
single byte flags in the following array. (The extra 5 values allow for the
|
|
fact that it can be legal to use low undeclared sound effect resource
|
|
numbers in the Z-machine for short beeps, though this is deprecated in I7.)
|
|
</p>
|
|
|
|
<p class="inwebparagraph">Pictures and sounds are identified within blorb archives by resource ID
|
|
numbers which count upwards from 1 in order of creation, but can mix
|
|
pictures and sounds freely. (For instance, 1 might be a picture, 2 and 3
|
|
sound effects, then 4 a picture again, etc.) ID number 1 is in fact always
|
|
a picture: it means the cover art, and is the I6 representation of the
|
|
value "figure of cover".
