SNDSEQ

SNDSEQ is a text lump first introduced in Hexen and used to define sound sequences. It is also used in the ZDoom family of source ports.

Syntax

Example of the SNDSEQ entry:

:Platform
	playuntildone	PlatformStart
	playrepeat	StoneMove
	stopsound	PlatformStop
end

Here:

• :Platform - definition of the sound sequence name;
• playuntildone - this command plays the sound specified after it until it completes;
• playrepeat - this command plays the sound specified after it in an endless loop;
• stopsound - this command specifies the sound that will be played after the sound sequence ends;
• end - ends the definition of the sound sequence.

Other commands:

• playtime - this command has two arguments. It plays the specified sound (argument 1) and then waits for a certain amount of time (argument 2), which is specified in tics;
• play - this command plays the sound specified after it;
• delay - this command waits for a certain amount of time, which is specified in tics;
• delayrand - this command has two arguments. It waits for a random amount of time, the minimum and maximum bounds of which are given in tics as arguments 1 and 2;
• volume - this command sets the volume at which all subsequent sounds will be played.

In Hexen source code processing of sound sequences is specified in the SN_SONIX.C file. It sets the maximum number of sequences in a SNDSEQ lump to 64 and also limits the sequence name to 32 characters.
