Ok thanks i will try to also add to this code. Thanks for all the help

I don't understand what u want please show some code

dan the man. i had a 2nd occurrence in the world like you said. fixed!

Like I said before, the 'eat' method is not going to do what you want because it looks for intersectors , not just objects in the world. And, of course 'getWorld().removeObject(Heart.class)' will not work because the 'removeObject' method requires an Actor object, not a class. I do not know why you tried that! Looks to me like you are throwing things to

Please do not start multiple discussion threads on the same issue. And please use 'code' tags for posting codes (refer to the 'Posting code? read this!' link below the reply box). Please refer to this discussion thread about this issue.

No -- as you only gave a condensed version of the error message you received. (for one thing)

Please do not start useless discussion threads. In other words, only start one if you have a legitimate programming issue or other question. And when you do, please include any information that may be helpful in resolving your issue.

You might want to show what you found for others to see. However, the following should be sufficient: <Code Omitted>

it worked! thank you so much :-)

Can you add your site to the list as well? Are you trying to run applets locally by opening a web page on your local machine?

Line 28 in your world subclass above is what is setting the rate of production of vehicles. Using 'Math.random()*5', the average value would be two. That means you will produce on average one car every other act cycle. At normal scenario speeds of between 50 and 60 cycles per second, you would be creating 25 to 30 cars per second, on average. Change the '5' to a much larger value. You can also add a constant value to it (for example: 'Math.random()*60+25').

Thank you very much! :)

Or if you want help here, explain what it is that you want that line of code to do.

First, the value of the parameter of 'getRandomNumber' must be a positive number. I do not see where 's' nor 'l' are set to any value other than zero. Second, only the values of 's' and 'l' are taken when used as part or all of a parameter expression. Finally, and I think this goes along with the previous statement, using 'getRandomNumber' returns a value that must be used either in an expression or assigned to a variable to be used later; otherwise, the value is immediately lost. In other words, lines 17 and 18 do absolutely nothing above, even if the value of 's' or 'l' was a positive n
