A simple ability that changes the BGM that's played when a specific player becomes a specific boss.
This checks the boss client's Steam ID (via checking SteamID32), and if it matches whatever is defined on the CFG config, it will play the BGM set that's specified on the boss's CFG.
"abilityX" // Replace X with the next available number.
"arg1" "<steamID32> ; <steamID32>" // Add as many Steam ID's as desired, separated by semicolons, make sure "sound_bgm_<steamID32>" is also present for that particular Steam ID.
"sound_bgm_<steamID32>" // Each Steam ID specified on arg1 must have its own "sound_bgm_<steamID32>" section. Replace <steamID32> with the specified SteamID
"path1" "<path to BGM>" // path to BGM file
"time1" "<BGM duration (float)>" // duration for BGM (seconds)
