Looks like a 3-d issue. Try having the crusher remove the brick when the crusher is down to a certain point instead of using solely collision detection. You can use the height of the brick as the amount of distance the crusher is to the platform to determine when the brick is destroyed.

Everything works, but that is because I put it like this:

This is going back! What i did afterwards was open the project in Eclipse. There were loads of errors, but all i wanted was to get the documentation which Eclipse produced nicely - that might be of some use to you?

If the 'reloadDelayCount' does what I think it does then something like this: <Code Omitted>

Start with a method to spawn a pig (in your World subclass): <Code Omitted>Now, you can call it when needed. For example, if you want to occasionally spawn one and limit the number of pigs in the world to, let us say,

There are different ways to "time" events. One uses the number of act cycles and another uses the system clock. The system clock should only be used when real-time is critical. To determine which is better in your case, be specific and describe exactly what the timer is going to be used for. Also, indicate at what times, if any, the value of the timer is to be displayed.

When an object is encountered when moving vertically (as well as horizontally, by the way), the position of the actor needs to be adjusted so that it is not constantly "in" the object. Use the value (sign) of 'vSpeed' to determine if the encounter was a head bump or landing on feet. Then you will know where to position the actor with respect to the encountered object.

Can you please show and example of a project that will not compile -- the World subclass of the project. HOW TO: open your windows browser and select the project folder. Find the JAVA file that is the initial World subclass and open it in a text editor. Then you can copy/paste the code here. If you cannot find the JAVA file in the folder, then list the files you do see and give the type of each file here.

Why did you create a new discussion here?

Oh sorry, I didn't see that Iron1 is a world class... Maybe this could work then: <Code Omitted> You could also add a new constructor: (or just change it to it if your scenario does not start in the IronManMode class) <Code Omitted> And then, you could use the following instead of the first code:

Try something like this? <Code Omitted>

You create a new 'count' variable each time the act method is executed. You might want to create 'count' (or maybe with a more obvious name) like this instead: (outside methods) <Code Omitted>

It says "to this variable" so I guess there isn't a 'sum' variable. You just use children=daughters+sons as this "assignment statement".

If the object is removed from the validateLocation-method, the act method will still finish executing (and giving you the error because it can't find objects in range if it isn't in the world). You could make the method return a boolean and if it is false (= the object was removed), you exit the act-method. As an alternative, you can just check if the object is still in the world after you called the method.
