Apply AffineTransform to Slick2D?

[P0jahn]

With, Java2D, I did like this:

1   2   3   4   5   6   7   8   9

@Override    public void draw(Graphics2D g)    {             AffineTransform transformer = new AffineTransform();       transformer.translate(-(Math.min(stage.width-stage.visibleWidth,   Math.max(0, main.posX - stage.visibleWidth  / 2))),                             -(Math.min(stage.height-stage.visibleHeight, Math.max(0, main.posY - stage.visibleHeight / 2))));       g.setTransform(transformer);    //...   }

This works perfect.
I tried similar in Slick2D:
   

1   2   3   4   5   6   7

@Override    public void render(GameContainer gc, Graphics g) throws SlickException    {       g.translate(-(Math.min(stage.width-stage.visibleWidth,   Math.max(0, main.posX - stage.visibleWidth  / 2))),                   -(Math.min(stage.height-stage.visibleHeight, Math.max(0, main.posY - stage.visibleHeight / 2))));    //...   }

This however, did not work at all. The result was that every thing in the window was black.
How do I fix this?

EDIT: This was an mistake by me. translate works fine for slick2d

Why not use object.draw(x, y, 0.0f); , and then in the gameLoop, set the x and the y to the mouse location.

I do not think that will be a good idea. I am trying to archive what I explained here:

Afaik, this can only be done with AffineTransform.
