Hi, I saw this message today: "unmappable character for encoding UTF8" I run greenfoot on ubuntu 11.04. It was a class that had some strange characters in a comment (this hapened because of changing computers, and i write in portuguese with accents). I fixed it and it executed as usual.

You can measure the speed yourself using System.currentTimeMillis() - it returns (as a "long") the number of milliseconds since 1 January 1970. You can simply print it to the terminal each act() and then calculate the difference by hand.

Thanks davmac; I appreciate your input. May God shower you with blessings!!

thanks so much

use the following code: <Code Omitted> now in the part where you set the Rotation, you may have to add or subtract 90, and remove the negative or something, because that depends on the rotation of your object.

If you could give me any advice on how to improve the scenario, it would be much appreciated! http://www.greenfootgallery.org/scenarios/3081

Ahh ok! Sry, I haven't seen this Method. xD Thank you very much!

MrCohen, just a few hints: first, in Java, if you use "new" then you're creating an object; otherwise you're just dealing with references (so as mik says, every time you call callStore() a new Store object is created - because callStore creates a new Store). Second, you generally don't need to worry about memory leaks; if there's no way to get to an object via references, Java's garbage collection system will reclaim the memory. Finally, don't worry about efficiency until it becomes a problem :) Creating a new store each time probably isn't going to be a problem, but if you want to avoid it

My bad! I forgot the 'X' was for exclusive. Thank you, davmac! (I've corrected mine, in case anyone sees it and does not see your correction)

It was just a link in a scenario to open in firefox etc. but I didn't realise you could put one in the description I'll do that instead thanks

Your player should keep score of it's own points respectively as it does whatever to gain points. Just have a variable for the players points in the player class, and the world class, and in the act method, send the variable across. <Code Omitted> Use a simple if statement to find which score is bigger, and allow that player to win.
