Figure 8-4. Clicking a colored block and selecting all similarly colored blocks touching it

The first thing we do in blockClickListener is test to see if we actually are in the
GameStates.STATE_WAITING_FOR_INPUT game state. If so, we drop into the main part of the
function and dispatch CustomEventSound.PLAY_SOUND event to play Main.SOUND_CLICK . This will to
give the user audio feedback for each click of the mouse.
Next, we retrieve the reference to the Block that was clicked ( e.block ) and put it into tempBlock .
We then fill clickedBlockArray by calling findLikeColoredBlocks and passing tempBlock as the
lone parameter. We will discuss this function in moment, but first, we'll finish the last few lines of
this function.
We then set all the necessary variables to create a GameStates.STATE_WAIT state ( framesToWait
= 15 , framesWaited = 0 , and nextGameState = GameStates.
STATE_REMOVE_CLICKED_BLOCKS ), decrement the plays variable (because the player just made a
play by clicking on a block) and set the gameState to GameStates.STATE_WAIT . This wait time of 15
frames will give the game a dramatic pause between when the user clicks a Block , the blocks that
match lighting up with a glow filter, and all the Block objects being removed from the screen in
GameStates.STATE_REMOVE_CLICKED_BLOCKS .
public function blockClickListener(e:CustomEventClickBlock):void {
if (gameState==GameStates.STATE_WAITING_FOR_INPUT) {
dispatchEvent( new CustomEventSound(CustomEventSound.PLAY_SOUND,

Main.SOUND_CLICK,false,1,0,1));
tempBlock = e.block;
clickedBlocksArray = findLikeColoredBlocks(tempBlock);
