Using Slick without GameContainer

[Troncoso]

I've decided to implement slick as it has many features that Java2D lacks, and is simpler to use than straight up lwjgl. My issue is, I really only want to access it's Graphics and Geom utilities (at the moment). Using the Graphics class to draw is straight foward (drawing on a Canvas), but I do this to update the image:

1   2

graphics = buffer.getDrawGraphics(); graphics.drawImage (bi, 0, 0, null);

here graphics is Java's Graphics class. Does anyone know how to do this using slick? Do I need to? Am I thinking about this wrong?

What is your question?

You don't need to create a game container. You can use your own game loop.

To use graphics it would look something like this:

1   2   3   4   5

... init ...    g = new Graphics(width, height); ... render ...    g.drawRect(...);

To use image graphics it would look like this, using the latest code:

1   2   3   4   5   6   7   8   9   10   11

... init ...     //creates a new FBO and texture     image = Image.createOffscreenGraphics(256, 256);     imageGraphics = image.getGraphics();     ... render ...     imageGraphics.drawRect(...);     imageGraphics.flush();     //draw to screen     g.drawImage(imageGraphics, x, y);

You should look into the code for GameContainer and AppGameContainer for more details on how Graphics is set up and used.

I understand how to use the Graphics class in slick, as I said. But, I believe you've actually answered my question. Thanks you.
