The discard.sound command unloads a sound resource from the memory heap.
Syntax
discard.sound(byt A);
Remarks
This command unloads sound A from memory.
Early versions of AGI did not include a command to unload sound resources. Since sounds were usually small and only used in limited circumstances, this was not usually a problem. Beginning with version 2.938, Sierra added this command to allow sounds to be unloaded once they were no longer needed, but ONLY in non-PC versions.
Possible Errors
Presumably, attempting to discard a sound that hasn't been loaded will cause errors and crash AGI.
NOTE: In the PC version of AGI, this command points to a null function, but the null function does not accept arguments. If you use this command on a PC, AGI will treat the argument value intended for this command as the byte value for the next command, which will almost always crash AGI. Do NOT use this command if you intend to run your game on a PC platform.
Example
<syntaxhighlight lang="agi"> discard.sound(12); [ this will crash AGI on a PC system
[ on non-PC system, sound #12 is unloaded
</syntaxhighlight>
Technical Information
| Required Interpreter Version: | Available in version 2.936 and above. |
| Byte-Code Value: | 175 (0xAF hex) |
NOTE: This command is only available on non-PC interpreters.
