FF8Audio Field ID -7850

Sound channel (must be power of 2)

Pan (0=left, 255=right)

Volume (0-127)

EFFECTPLAY

Description

Plays a sound effect through the given sound channel. The channel is important because it’s the parameter used in SESTOP.

Unlike EFFECTPLAY2. For example, when you touch a save point, it calls EFFECTPLAY on sound 30, which turns out to be sound 7880 in field IDs.

Sound channel 0 appears to be able to play sounds while it’s already playing sounds. Each other channels can only play one sound at a time.

The handler pops all four values (volume first, then pan, then channel, then the sound id) and calls PlayWorldSound(soundId, channel, pan, volume). Returns 2.

PC handler: SCRIPT_EFFECTPLAY.
