Editing the objects sound
Submitted by Weird Person on May 29 2005.
I had the idea of edit the sound of each object. If you change
the "ring" sound, all the objects using that sound will have
the new sound. This list is for edit each object, without edit all the
objects (If you change the ring sound for the super ring monitor, only
the computer will have the new sound, not all objects who use that
sound. That's the reason of this list! But if you change an object, all
the copies of that object will have the same sound effect).
Basically, these notes are for those who don't want see the programming
stuff of the objects to change its sounds...
Editing the sound is quite easy. Take the value of a sound in the sound
test. Add $80 to it, and you get the new sound value. It's only one
byte!
The following list is the offset where you will place the new
sound value. I will not make a list with the values and its respective
sounds. Use the trick (explained above) and sound test.
