Here's a pseudo-code example that makes a circle: * The debug method evaluates a boolean and can * be set to 'true' for any object */ // The debug method is set to 'false' by default // Here's how you can turn it on for a circle object: var circle = new Circle(50); circle.

Thus, double click is kind of like my default option here. Either: Translate the context by the negative offset within the object for the center of rotation, and then draw the object at 0,0, or; Draw the image using the negative offset within the object for the center of rotation. @ClaytonEngle I see, because it'll most likely either affect the last one or it'll affect both of them at the same time and put them in the same place if you want to declare them both before creating the shape, so basically the 'static' makes the clients (variables) inside the method reference the method alone rather than the class, object, and method. So sorry if it's stupid question. If this is the ending click, clear the isDrawing flage and draw the rectangle.
