Re: Updating an object on the screen...

Hi Carl,

This isn't a problem, it's the normal order of business. You update
the position, regenerate the Location, and call redraw on the layer.

Alternatively, you could call

layer.repaint(long tm, int x, int y, int width, int height);

which may (I haven't tried it) set a clipping area for you, so that the
repaint area is restricted. This method is inherited from
java.awt.Component, if you want to look up the signature.

Hope this helps,

Don
