	var Model = require('model');
  • ¶

    A class for managing the score. Extends Model.

    Note that you should set the game attribute on construction and that dryspell alternates between -1 and 0 during a combo.

    Attributes

  • ¶
    • combo (Number): The number of plays in a row that have cleared.
    • dryspell (Number): The complement of combo.
    • game (Tetris): The game being scored.
    • score (Number): Duh.

    Events

  • ¶
    • score (current score, combo): Triggers when a score is calculated.
    	module.exports = Model.extend({

		attributes: {
			combo: 0,
			dryspell: 0,
			game: null,
			score: 0
		},


		initialize: function () {
			var game = this.get('game');

			game.on('clear', this.score.bind(this));
			game.on('lock', function () {
				var dryspell = this.get('dryspell');
				this.set({ 'dryspell': dryspell + 1 });
			}.bind(this));
		},

    sk.score(rows)

  • ¶

    Adds to the score based on the number of rows cleared.

    This method is registered as a handler for the clear event of the game, which is called when the player clears one or more rows in a turn.

    Params

    • rows (Array of Integers): The indicies of the rows cleared.
    		score: function (rows) {
			var dryspell = this.get('dryspell');
			var score = this.get('score');
			var combo = this.get('combo');
			var bonus = 0;
			var points = 0;
  • ¶

    -1 because the upcoming lock event will bump it to 0

    			if (rows.length > 0) dryspell = -1;

			if (dryspell > 0) combo = 0;
			else combo += 1;

			if (rows.length >= 4) bonus += 1;
			if (rows.length >= 3) bonus += 1;
			if (rows.length >= 2) bonus += 1;

			points = (rows.length + bonus) * combo;
			score += points;
			if (points > 0) console.log(score);

			this.set({
				'dryspell': dryspell,
				'score': score,
				'combo': combo
			});

			this.trigger('score', score, combo);
		}

	});
});
