This class is relatively simple, declared the background diagram, load the specified graphics in the constructor, pay attention to the suffix
The name is PNG. When the IMG is constructed, I remember to have an exception. Image.createImage () is through
The resource file loads the PNG image (CreateImage has many other ways). Use Graphics to lose
The way to call when the image is: VoidDrawImage (Image, Int X, Int Y, Int Anchor)
Here is just a simple background, of course, a game will not be as simple, other methods, etc.
After writing this, you will slowly introduce.
Auxiliary ABOUT

Public void CommandAction (Command C, Displayable D) {
IF (c == cmdback) {
MAINSCREEN.GOBACK ();
}
}
}

THIS.APpend ("Developer") and this.append ("Write Name") Add a text title to
The final end of the Form object returns the location of the added object. Equivalent to calling Append (New
StringItem (NULL, STR)) is just a simple application of the FORM class.
There are also three important classes without writing, and you can do it in the near future. If there is anything wrong with
Please ask, there is anything you don't understand, I will try my best, thank you Mingjava.
