Move BufferedImage with Keys

问题

I have a background image on my 2D game, and I would like to know how I could move this image around with keys? I was trying things like:

background.getX() + 3;

But that wouldn't work as getX() isn't applicable for BufferedImages.

How can I do this?

回答1:

You're going to need two things.

1. You're going to need to know the position of the image. A simple Point object should suffice. This tells you where to draw the image...
2. Some where to catch key board events. For this I would suggest the key bindings API, as it does not suffer from the same issues and KeyListener
