Miscalculation when drawing rectangles with AndroidGraphics.drawRect() (ch06-mrnom) #79

Open GoogleCodeExporter opened 9 years ago

GoogleCodeExporter commented 9 years ago 
In the com.badlogic.androidgames.framework.impl.AndroidGraphics:

http://beginning-android-games.googlecode.com/svn/trunk/ch06-mrnom/src/com/badlo
gic/androidgames/framework/impl/AndroidGraphics.java

the method drawrect() is like this:

 public void drawRect(int x, int y, int width, int height, int color) {
        paint.setColor(color);
        paint.setStyle(Style.FILL);
        canvas.drawRect(x, y, x + width - 1, y + WIDTH - 1, paint);
    }

I have put on allcaps the mistake: the call to canvas.drawRect() is using the 
witdh parameter when drawing BOTH the width and the height of the rectangle. It 
will never draw rectangles of the specified height the user wants.

At first I thought I hadn't copied the method correctly from the web and I was 
surprised when I saw the evident mistake.
