I defined a global var(a table) in my plugin script.
But every time i restart the world, The plugin keep those global var even i clear the 'save_state'.
I dont want the plug keep those global var.
My question is
1.how to make a clean plugin global namespace every time the plugin or the world restart.
2.Where are those plugin global var be stored?
Thank you!

Some example code would help here.

Don't put variables into the plugin (in the <variable> part) because that will overwrite any variables saved in the state file.

If you have "save_state" set then each world/plugin combination saves its plugin variables into a file in the "state" subdirectory. The file name is a combination of the plugin ID and the world ID. eg.

Thank you very much Nick.
I check the code, found that it load a serialized table into a global var from the state file every time the plug installed.
I have always thinked that the var stored in _G namespace could also be stored when i leaved the world.
and now i see, Only the var saved in the state file could be kept, Is that right?
