Keeping Score

Winning, Losing, and Slaying Bricks.

Display Score, Lives, and Level

function game_reset() {
    score_set(0);
    level_init(1);
    ballsLeft = SPARES_START;
    $('spare1', 'spare2', 'spare3').each(
	function (x){ x.style.display = 'block' });
}

    game_reset();

var score = 0;

function score_set(value) {
    score = value;
     $("score").innerHTML = '' + score;
}

#levelarea, #level, #scorecard, #score {
  position:absolute;
  top: 282px;
  color: white;
  font-weight: bold;
}

#scorecard {
  left: 300px;
}

#score {
  left: 350px;
  width: 45px;
  text-align: right;
}

#levelarea {
  left: 150px;
}

#level {
  left: 200px;
}


.spare { top: 282px;}
#spare1 { left: 4px; }
#spare2 { left: 24px; }
#spare3 { left: 44px; }

    <div id="scorecard">score:</div><div id="score">0</div>

    <div id="levelarea">level:</div>
    <div id="level">1</div>

    <div class="spare" id="spare1"></div>
    <div class="spare" id="spare2"></div>
    <div class="spare" id="spare3"></div>

Increase Score on Collision with Brick

function score_inc() {
    score_set(score+1);
}

                score_inc();

Decrease Lives on Collision with Lake

                loseLife();

function loseLife() {
    soundManager.play('fall');
    if (ballsLeft == 0) {
        // game over
        //posted_scores = false;
    } else {
        if (el = $("spare" + ballsLeft)) {
	    el.style.display = 'none';
	}
        ballsLeft--;
        ball.stickToPaddle();
    }
}

var ballsLeft;
var SPARES_START = 3;

Increase Level after Slaying Final Brick

function level_init(level) {
    bricks.each(function (b) { b.reset() });
    Brick.count = bricks.length;
    current_level = level;
    paddle.center();
    ball.stickToPaddle();
    Element.update($('level'), current_level.toString());
}

Firebug - Kill All But One Brick

Here's a simple trick to avoid having to play through the whole level.

>>> Brick.count = 1

The bricks stay on screen, but the next on you hit triggers the level clear action.
