need help permanently changing music via script

[Toughtreaty2]

Hello, I hope whoever is reading is in good health. I want to create a cutscene in which after a certain flag is set, the music of the map should permanently change even after transitioning through different maps but i am having a problem. It works fine if i am entering the map from a route but if i enter through a door the music reverts to the previous one. I am using the Mapscript on Transition to run the script if anyone can help i would really appreciate it.Here's the script
script musicchange {
if(flag(FLAG_UNUSED_0x4AA)){
playse(MUS_DUMMY)
setweather(WEATHER_RAIN_THUNDERSTORM)
doweather

}}

Yeah, if you want to handle that through an overworld script you'll want to add a map script ON_WARP_INTO_MAP_TABLE to activate a script based on your conditions that calls the playse macro.

Alternatively, you can do it directly on the C side like Game Freak did a number of times.
Check GetLocationMusic, GetCurrLocationDefaultMusic and/or GetWarpDestinationMusic for more info.
