Create an actor. Give it the image with the Try again text on it. When it is clicked, restart the game. Do it step by step. With which step do you need help? What have you tried?

You could also just skip the actor and use the Game Over Screen background image as one big button. Just draw some text (or a text image) onto the background indicating that a click will restart the game and add the code for it.

https://www.greenfoot.org/files/javadoc/ Click that link and then choose the "Greenfoot" class. There are a few methods relating the mouse. The method you want to use is probably 'Greenfoot.mousePressed'.

It doesn't works if the mouse clicked the button Here is my code: Actor Frosch = getOneIntersectingObject (Frosch.class); if (Frosch != null) { World myWorld = getWorld(); GameOver gameover = new GameOver(); myWorld.addObject(gameover, myWorld.getWidth()/2, myWorld.getHeight()/2); TryAgain tryagain = new TryAgain(); myWorld.addObject(tryagain, 300, 300); Actor TryAgain= getOneIntersectingObject (TryAgain.class); if (mouseClicked) { if( mouseClicked!=true) { Greenfoot.setWorld(new frogfly()); } } myWorld.removeObject(this); Greenfoot.stop(); }

Remove the check for the mouse click there. Just add the object. Place this in the TryAgain class:

If you mean for a scenario that is in a paused state (the 'Pause' button in the greenfoot frame was pressed or a Greenfoot.stop() command was executed), then no. When a scenario is paused in this way, no code within it is executed except what may be done manually.. I mean, you could add a 'public void start()' method to execute a Greenfoot.start() command in your world subclass so that you can manually start it by executing that method; but, with a 'Run' button so easily accessible, what is the point?! You can keep the scenario running and "pause" the action within your project in other ways, however. Is that what you are wanting to do? If so, do you want the game world to continue to display while paused or some other world that states that your game world is paused?

Please note the first two methods here.

Please elaborate. I am not sure what you are asking here. Or, maybe you did not realize that 'here' in my last post is linked to a page.
