How do you add/subtract width and height on resize no matter how they resize/ check if resize

evilhatter

Hello, I am Try to make it to when people resize the window/surface it add or subtracts height and width no matter how they resize it. Similar to the game window in TERA.

I Have used if statements checking the current size to the change but it simply did not work.

I don't believe this can be done... when you check width and height variables, it is looking for the canvas

I never understood what you asked, but to resize the window in code, use surface.setSize(width, height)

See also the settings() reference page:

The settings() function is new with Processing 3.0. It's not needed in most sketches. It's only useful when it's absolutely necessary to define the parameters to size() with a variable.

@jeremydouglass Can the settings function be called in code without causing errors? surface.setSize(width, height) can be used anywhere in the sketch, even in draw().
@evilhatter Anyways, the window is not resizable unless you specify with surface.setResizable(true) , so I don't see what the problem is.

Can the settings function be called in code without causing errors?

No. It is called by Processing once, at startup. This would be in addition to calling surface.setSize() -- or, as an alternative, you might be setting a maximum size programmatically and then and scale it e.g. with image().

To the original question: I'm not sure if Processing / Java can access a variable that changes whenever you manually resize the sketch window using the mouse (assuming it has been set as resizable.

Exactly what I thought. What exactly is the question anyway?
