Argument

none

Stack

Final Volume (0-127)

Frame count

ALLSEVOLTRANS

Description

Fades the volume of all sound-effect channels to a target level over a duration. The handler pops the frame count first (top of stack) and the final volume second, then calls Sfx_SetAllChannelsVolumeTrans(volume, 2 × frame count) — the transition step count is the frame value doubled. Returns 2.

Note the push order: the final volume is pushed first, then the frame count (the reverse of most *TRANS opcodes).

PC handler: SCRIPT_ALLSEVOLTRANS.
