Well, in order for that to compile (so you could see what behavior you have achieved), the line would need to be changed to this: <Code Omitted>

With this, you can use 'getX()' and 'getY()' to set the values of 'x' and 'y' when a button is clicked: <Code Omitted>

As far as running scenarios on the site, what do you see on the left below the description of the scenario. Do you see any evidence of an applet?

That was a slip. Actually, it should be 'floorObj.getImage().getWidth()'. I have been around long enough to be aware that at one time you could call those methods, 'getWidth' and 'getHeight', directly on the Actor object and do catch myself still trying to do that occasionally.

Please show the code for this actor -- and for the laser beams.

ok thank you

Provided that you did not change anything at all in the 'toonConditions' method and the status bar was indeed working, then the only thing that could influence the status bar from in the QuokkaModel class is the 'getHealth' method. Where is it code? However, it is yet beyond me how the status bar could possibly work with the given code. The thing is that I cannot see how the bar would decay because it looks like you are filling a smaller rectangle over the full rectangle -- which would not actually change the appearance of a full status bar.

Your actor does not have a height (or width) -- but the image of the actor does. Use 'getImage().getHeight()'. You could, although I would not, give the actor a height and a width if you wanted to by adding the following methods to the class: <Code Omitted>

I just noticed your subsequent post above (the one immediately following your initial post). The scoreboard does not need to see the horcrux. Remove lines 4 and 5 from the 'act' method of the ScoreBoard class (as shown above). Then change the name from 'act' to 'updateImage'. Finally, change the 'addScore' method to this: <Code Omitted>Also, you should have a constructor for the class (to set the initial image): <Code Omitted>Now, let me understand what you are trying to do in the

Thanks! Very helpful @danpost

The class name should start with an uppercase letter. So change 'health' to 'Health' although 'Healthbar' would be better. <Code Omitted> In the loseHealth-method, you could add the following line (before the call to the update-method) to decrease the health: <Code Omitted>

thanks a lot

Buttons should remain fairly dumb in that they should only react to mouse actions, if anything -- altering their image depending on what the mouse is doing (mouse hovering state or mouse button pressed state). The world is what should control the main actions of the simulation -- checking for clicks on buttons currently in the world and responding to them. The world should also hold a reference to the correct button that answers the current question. Let us say you have a Text class whose objects can display the questions as they are posed and a Button class whose objects can display the

Thanks, Dan!
