Hi all, I want to create a better texture for my worms szenario and I need to know if it's possible to overdraw and image with a transperency, so that the image is transperent at this part. And I also need to know where I can get a transperent color. I haven't found such a color in the api java.awt.Color;

getIimage().clear() will make any actor object's image transparent (if that is what you mean); and, new Color(0, 0, 0, 0) is transparent (although, the first three parameters can be anything in the 0 to 255 range). If you are just trying to 'hide' the object, you can use getImage().setTransparency(0) and then 'show' the object later with getImage().setTransparency(255). Be aware that the act method will still run while the object is in 'hide' mode; but you can get around that by using 'if (getImage().getTransparency() != 0)' around the code within the act method.

If you are hoping to change a part of an image to transparent, then check out the code of my Spot-lights Demo

Another question: If I use setColorAt(x, y, new Color(0, 0, 0, 0)) the Image is transparent at the coordinates. But if I use setColor(new Color(0, 0, 0, 0)); and fillOval(x, y, deltaX, deltaY); there is no change at the image. Am I doing something wrong or should the Image act like this?
