ActionSprite

An Action sprite is a sprite that may be pressed to generate an ActionEvent that will trigger a method in your Controller.

=Implement the ActionSprite Interface= If you already have a class that extends Sprite, have that class implement the ActionSprite interface. Here is an example of how to do this for an ImageSprite.

public class ActionImageSprite extends ImageSprite implements ActionSprite { public ActionImageSprite(BufferedMirage image, String action) { super(image); _action = action; }   public String getActionCommand { return _action; }   private String _action; }

=Add Action Method to Controller= Inside your Controller class, add the method to be triggered. You can have multiple methods or just a single one. Let's assume that we want to have two different possible action events. The methods could look like these.

public void plusClicked { // add lines that you want executed // if the plus sprite is clicked }   public void minusClicked { // add lines that you want executed // if the minus sprite is clicked }  =Use ActionSprite in BoardView= Inside your BoardView class, create one or more instances of your ActionSprite. Here is an example using ActionImageSprite.

BufferedMirage image = ... find the image ..... ;      _plusSprite = new ActionImageSprite(image,                         "plusClicked");

Notice that the String being passed matches the name of the method in Controller. After creating the instance ActionImageSprite, treat it exactly the same as a normal Sprite. When a player clicks a non-transparent part of the sprite, the correct method will be triggered in Controller.
