Changing text

This is what I have so far: import greenfoot.*; import java.awt.Color; public class Label extends Actor { public Label() { updateImage("Oh no!"); } public Label(String text) { updateImage(text); } public void setText(String text) { updateImage(text); } private void updateImage(String text) { setImage(new GreenfootImage(text, 90, Color.BLACK, new Color(0,0,0,0) )); } }

Right now, I only know of you using the label object in the Boat class. No.'getWorld().removeObject(/* label reference */);'. But, it may depend on which class your removal code might be in.

I think I'll be using it in a different class as well, the Sled class. I tried getWorld().removeObject(new Label1()); and it didn't go away

No. creating a new object and trying to remove it before adding that label to the world will not work; nor will it remove the label object that is already in the world. You may want to keep the Label object in the world regardless of whether text is showing or not. Since it has a transparent background to the text, if you set its text to an empty String, 'setText("")', it will be invisible and ready to show new text at any time. You can add it to the world in your world constructor, like any other object you add at load time. And you can keep a reference to it in the world in a 'public static' field so that any class can change its text easily with '/* world name */.label.setText("new text");'.

You would put it in your world class as a class field:
