How to read canvas.width/height?

Or the width and height of an object after the canvas has been scaled? Is it possible? Using the runtime.width/height commands seem like they could do the trick but I don't know how to use them inside events; the editor complains that runtime is not a behavior when I try.

Use the system "compare two values" and input your values there

Note that compare two values does not do any picking...

You're confusing javascript with Construct 2 expressions. In the Construct 2 editor it's WindowWidth and WindowHeight, but don't confuse them with the viewport.

That worked. Thanks :)
