Java Canvas - Rectangle2D Scales When Moving
I am drawing a series of rectangles on canvas. The rectangles should move at an angle. For some reason, when they move, they expand:
xPos += xSpeed; yPos += ySpeed; updateBounds(xPos, yPos, width, height);
My UpdateBounds method:
public void updateBounds(double x, double y, double w, double h) {
bounds.setRect(x, y, w, h);
}
Bounds is a Rectangle2D object. And my drawing method:
g.fillRect((int) bounds.getX(), (int) bounds.getY(),
(int) bounds.getMaxX(), (int) bounds.getMaxY());
Why am I getting this behavior?

Graphics.fillRect () takes a width and height parameter, not the largest x and y position to draw the rectangle.
The third and fourth parameters fillRect
must be Rectangle2D getWidth () and GetHeight () .
As a reference, a link to what getMaxX () will receive .
