Hi guys, I'm trying to make my characters shows some text messages. I can make them show the messages but I can't remove the messages. I'm using the method getWorld().getBackground().drawString ..... so the dialog stays on the screen forever. How can i remove the dialogs?

You have to overdraw them. Or if your background is an image you have to load the file new and change the image. Another way would be to use objects for drawing the strings so that you can remove the objects.

If I use the method again it will overwrite the other dialog. The bg is an image, are you saying to reload the bg image?

To remove the text: change the drawing color for the background to the background color and re-draw the same string at the same location.

If your background is multi-colored, then you should probably save the background image in an instance GreenfootImage field before writing any text on it. 
// add this instance object field to the class
private GreenfootImage bgBaseImage;
// after the base background image is set, in the world constructor
bgBaseImage = new GreenfootImage(getBackground());
// then you can write on background

// to remove the text
setBackground(new GreenfootImage(bgBaseImage));
