Field SFXID (in the SFX list for that field)

Stack

Pan (0=left, 255=right)

Volume (0-127)

Channel (must be a power of 2)

EFFECTPLAY2

Description

Plays a sound effect through the given sound channel. The channel is important because it’s the parameter used in SESTOP, so you can theoretically have 20 sounds playing at once. 0 doesn’t seem like it’s a usable channel, but this is untested.

Note: It seems each area can have a maximum of 32 sounds predefined (meaning sound ID 31 is the highest you can play with this). You have to use EFFECTPLAY to use more than 32 sounds.

PC handler: SCRIPT_EFFECTPLAY2.
