Here is my code in World: Title title = new Title(); NextPage nextpage = new NextPage(); /** * Constructor for objects of class GreenfootWorld. * */ public GreenfootWorld() { // Create a new world with 600x400 cells with a cell size of 1x1 pixels. super(600, 400, 1); prepare(); if(Greenfoot.mouseClicked(nextpage)) { title.clearImage(); } } I dont have anything in next Page. in Title i have: public void act() { } public void clearImage(){ getImage().clear(); } I'm making a book and I'm trying to clear the title when the nextImage button is clicked. I'm sure I made a simple error because in the Greenfoot API it says clear() is the method. Please respond fast!!!

First, you need to add the Title object into the world. Add this line in the constructor of the 'GreenfootWorld' if it isn't in the 'prepare' method yet: 
addObject(title, 100, 100); //change numbers to where ever it has to go
Then, the check for a mouse click should be in the act method, not in the constructor.

Thank you! I had the addObject line but I didn't see the constructor. I thought there was only the act method. Thanks a lot!
