I want to modify Greenfoot's constructor code, for MyWorld and actors, but where is the script located? I know what I'm doing, I only want to know what is the path to the text file.

If you want to modify the templates for when the classes are created, you can use any text editor finding the files at: greenfoot/lib/english/greenfoot/templates

alright, thank you very much!!

Animation with Image Arrays overriding each other

It is not easy to give advice here. On one hand, there is lag due to reading in multiple images during game time. On the other hand, there is a lot of memory used up if the images are loaded up front. However, that is what I think you should do -- load all the images into arrays when you create the character. With these field arrays, you can add one more field array for the one that is currently being used (by setting it equal to one of the others).

You can use the Color class provided by Greenfoot. It is very similar to java.awt.Color. You have to create an image, set the color and then use the drawString method to draw text with the given text color to the background.

I have a new error... it says "method createBullet in class MyWorld cannot be applied to given types: required no arguments: found: int, int, int reason: actual and formal arguments lists differ in length"

Add parameters to the method (line 24) to suit your arguments (those values you are trying to pass to the method).
