mouse click persistent effect
Mar 26th, 2010, 1:48pm  
This question may have been asked elsewhere, but if so I have been unable to locate it.  My apologies in advance.  I am still new to Processing.

I want my users to click on a object and have that object toggle in size (expand or shrink) and then persist at that size until it is clicked again.  Currently the object only expands for an instant and then shrinks again.  I know mousePressed() is only called once, but there must (I assume) be a way to add this basic functionality to a Processing program.  Any thoughts or help would be most appreciated.

If it has only two states, large and small, just have a boolean global variable... and toggle it between true and false on mouseReleased.
Then when you draw it, draw it big or small depending on the value of the boolean variable.

Just solved my own problem.  I was thinking about it 100% the wrong way.  For those interested, create a boolean value in your object's subclass, toggle that value based on mousePressed, and then in your draw() method choose which way to display your object based on that boolean value.

@Giles many thanks.  I didn't see your response until after I'd posted.
