PlayState vars require "PlayState." before them in song scripts

[THEkatinamicrowave]

I have a song script

It throws this error

I add this before it

It works now

but also "health" isn't defined by PlayState but it's not complaining about that

Why and how do I fix it

Playstate.instance.difficulty

[THEkatinamicrowave]

PlayState.difficulty works. You're just adding more
I'm asking why just putting "difficulty" doesn't work
I don't have to put "PlayState.health"; it just knows that "health" refers to the playstate var
what's different?

You gotta place PlayState. before the variable names because those variables are static
everytime you wanna access a static variable in a script from somewhere in the code (excluded scripts) you always gotta do it (in this case with PlayState)
you can see which variables are static either in the api or in the actual code

everytime you get variables in song scripts for example if you dont specify where they're from (for example like PlayState.SONG you're specifying that its from PlayState) it defaults to PlayState.instance.yourVariable
Thats because scripts parents are the class' instance and so everything it tries to get from the outside it defaults to either that or inside the script UNLESS you specify where its from, welcome to coding lmao

Although NOT every variable is static, remember that

SONG does not need to be defined by PlayState

SONG is a static variable

why does this work

should have warned about this before my bad, SONG is a special case because we defined it in the code that it refers automatically to PlayState.SONG
although iirc its the only special case we placed for normal song scripts

ooooooooh ok thank you bothj

also to make you understand even more
static variables are different from normal variables because for example, if the object gets destroyed, every variable should also get destroyed aswell and you could say it becomes null to make it easier, well static variables instead even if the object gets destroyed they survive.

So how do we make static variables be accessible even after an object gets destroyed and so its null? We can't for sure do theObject.thatvariable if the theIbject is now null; i'll tell you how: TheClassName.thatVariable
