GleamAnimation

From Gardenwiki

A GleamAnimation is an easy way to temporarily change the color of an ImageSprite. This is useful if you want to draw attention to a certain part of the board. ZenBilging uses GleamAnimation to turn the combo yellow when a player makes a clear.

Here is the way ZenBilging uses GleamAnimation.

1. In the ZenBoardView class, import com.threerings.media.animation.GleamAnimation. You will likely also want to import java.awt.Color .

2. In the ZenBoardView class, the following method is added:

       /** make one bilge piece gleam */
   protected void gleamSpot(int row, int col, Color c) {
       GleamAnimation ga = new GleamAnimation(getSpriteManager(), 
               bilgeSprites[row][col], 
               c, 1000, 1000, true);
       addAnimation(ga);
   }   // end gleamSpot

3. The gleamSpot method is invoked where needed, giving the array coordinates of the ImageSprite and the color to be used. For example:

       gleamSpot(r, c, Color.YELLOW);

It is not necessary to add a method to handle the GleamAnimation. The parameters are a SpriteManager object, a Sprite object, a Color, the number of milliseconds to take to fade the color in, the number of milliseconds to take to fade the color out again, and a boolean. A boolean of true leaves the Sprite's image behind after fadeout. (More experimentation needs to be done to determine exactly what the boolean of false does.)
