If this class is a subclass of my main class, it works.  If I move it to its own class and add all the imports that Eclipse wants, I get an error.

import java.awt.Image;
import java.awt.Image.*;
import java.awt.image.CropImageFilter;
import java.awt.image.FilteredImageSource;
import java.util.HashMap;
import java.util.Map;



public class Chara {

   //Create a list for the Sprite images
  //ArrayList<Sprite> sprite = new ArrayList();
  Map<String, Sprite> sprite = new HashMap<String, Sprite>();
   int angle;
   int lastAngle;
   int x;
   int y;
   float gx;
   float gy;
   
   public Chara(Image SpriteSheet)
   {
     
      sprite.put("fl", new Sprite());
      sprite.get("fl").img = createImage(new FilteredImageSource(SpriteSheet.getSource(),
            new CropImageFilter(0, 0, 32, 32)));
   }
}


The error is: The method createImage(FilteredImageSource) is undefined for the type Chara
I don't know how to fix it.

Ok, so I solved it.  Chara() needs to extend Component.  I figured that out after looking at the definition of createImage when Chara() was a subclass.  I don't know why, my main class only extends Applet...  What ever I guess, Onward.

Correct me if i am wrong but applet is sub class of component and inherits all components fields/methods.
By the way do yoy initalize your class (new) before calling its metods ?

@Fokusas, You're probably right.  And yes, I do initialize multiple copies of my class Players 1 - 8.
