How exactly do I load the environment settings in the code for my world?

I tried by using
But that gives me an error that it can't convert the 'this' pointer.

EDIT: Secondly, can we load GuiObjs from UID?

Hi,

1) drag and drop environment element onto opened world editor viewport (this will assign Game.World.settings().environment)
2) in the codes if(Game.World.settings().environment)Game.World.settings().environment->set();

you can use
GuiObjs obj;
obj="jakshdkagsdjahsdgj"; // use Ctrl+Shift+RMB on proj element to copy its text file ID here

Both work fine, thanks.
