Re: [sc-users] Env.levels problem - unexpected post window output

Hi

You need to use the copy message.  Basically, assignment is by
reference.  If you want a distinct object, use -copy.
http://doc.sccode.org/Classes/Object.html#Copying

(
~wenv = Env(
	levels: Array.fill(3, {arg j; j}),
	times: Array.fill(2, {arg j; 1/2;}),
	curve: \lin
);
("~wenv before:" + ~wenv.levels).postln;

~tempenv = ~wenv.copy;
~tempenv.levels = ~tempenv.levels*2; // update

("~wenv after:" + ~wenv.levels).postln;
("temp:" + ~tempenv.levels).postln;
)
