Bitzz - The Game

Created by Tiago Almeida with MelonJS and Scoreoid


Game Objective:
- Be fast and reach the black portal;
- Avoid die;
- Enjoy as well.

Features:

JavaScript Code

Modified code from minified version 0.9.2 of MelonJS

This code enables enter key to pause/resume game and time.

    document.onkeyup = processKey;
		function processKey(evt) {
			var keyID;
			if (window.event) {
				keyID = window.event.keyCode
				
			} else if (evt.which) {
				keyID = evt.which
			}
			if (keyID == 13) {
				for (var i = 0; i <= 0; i++) {
					if (PauseOn) {
						v.resume(true);
						PauseOn = false;
						swStart('beg2', '+')
						 break;
					}
					if (!PauseOn) {
						v.pause(true);
						PauseOn = true;
						me.state.onPause();
						swStop('beg2')
						 break;
					}
				}
			}
		}

This code saves level and corresponding time in both cookies and string. Also clear all the checkpoint id's and positions.

LevelEntity = InvisibleEntity.extend({
	(...)
	onCollision: function() {
		var currentlevel = this.gotolevel;
		currentlevel = currentlevel.slice( - 2);
	    document.cookie = 'level_time=' + swObj.cycle + '; expires=Thu, 2 Aug 2022 20:47:11 UTC; path=/';
        document.cookie = 'level_id=' + currentlevel + '; expires=Thu, 2 Aug 2022 20:47:11 UTC; path=/';
		document.cookie = 'level_' + currentlevel + '=' + swObj.cycle + '; expires=Thu, 2 Aug 2022 20:47:11 UTC; path=/';
		str_url="?"+currentlevel+"?"+ swObj.cycle
		lvl_id[currentlevel-1]=swObj.cycle
		for (var i = 1; i <= checkpoint_array.length; i++) {
			checkpoint_array.pop();
			checkpointx_array.pop();
			checkpointy_array.pop();
		}
		this.goTo()			
	}
	
});

This code let the player jump higher while holing jump key after jumping.

	h.isKeyPressed = function(r) {
		if (k[r]) {
			if (n[r]) {
				d[r] = false;
				k[r] = true
				
			}
			return true
			
		}
		return false
		
	};

This code changes the initial loading for a custom loading.

var a = me.ScreenObject.extend({
	(...)
	draw: function(d) {
		var f = d.canvas.height / 2;
		me.video.clearSurface(d, "black");
		f += 40;
		var e = Math.floor(this.loadPercent * d.canvas.width);
		document.getElementById('rungif').style.left = e - 40 + 'px';
		document.getElementById('rungif').style.top = f - 32 + 'px';
		d.fillStyle = "white";
		d.fillRect(2, f - 10, e - 4, 32)
	}
});

Code from main.js for creating game.

This code create the secondary parallax movement between player and background.

var PlayerEntity = me.ObjectEntity.extend({
	(...)
    update: function() {
		(...)
            updated = this.updateMovement();
            if (this.pos.x >= 200) {
                me.game.viewport.move(5, 0)
            }
});

This code saves all the checkpoints id's and positions when loading all objects, and onCollision, verify which checkpoint was touched and saves his id in a string ( same logic applies to Teleport object ).

var Checkpoint = me.CollectableEntity.extend({
    init: function(a, c, b) {
        (...)
        checkpoint_array[b.id] = b.id;
        checkpointx_array[b.id] = a;
        checkpointy_array[b.id] = c - 50;

    },
    onCollision: function(res, obj) {
        me.audio.play("checkpoint");
        for (var i = 1; i <= checkpoint_array.length; i++) {
            if ((obj.pos.x - 100 <= checkpointx_array[i]) && (obj.pos.x + 100 >= checkpointx_array[i])) {
                checkpoint_cookie = i;
                this.setCurrentAnimation("check");
            }
        }
        this.collidable = false;
    }
});

Code to get Cookies Value.

function getCookie(c_name) {
    var i, x, y, ARRcookies = document.cookie.split(";");
    for (i = 0; i < ARRcookies.length; i++) {
        x = ARRcookies[i].substr(0, ARRcookies[i].indexOf("="));
        y = ARRcookies[i].substr(ARRcookies[i].indexOf("=") + 1);
        x = x.replace(/^\s+|\s+$/g, "");
        if (x == c_name) {
            return unescape(y);
        }
    }
}

Code for call and get response from Scoreoid

This code calls createPlayer function of Scoreoid for creating an user with his corresponding score (time).

function createScore2() {
    $.post('scoreoid_proxy.php', {
        action: 'curl_request',
        method: 'createPlayer',
        response: 'xml',
        username: username_player,
        score: score_player
    }, function(data) {
        console.log("Data Loaded: " + data);
        var error = data.indexOf("A player with that username already exists");
        if (error >= 0) {
            scoreError(1)
        } else {
            scoreError(0)
        }
    });
}

This code parses the XML response from Scoreoid with top 10 highscores and corresponding usernames, and display them on corresponding inputs.

var playercont = 0
var scorecont = 0
function seeScore() {
    $.post('scoreoid_proxy.php', {
        action: 'curl_request',
        method: 'getBestScores',
        response: 'xml',
        order_by: 'score',
        order: "asc",
        limit: "10"
    }, function(data) {
        //     alert("Data Loaded: " + data);
        console.log("Data Loaded: " + data);
        $(data).find("player").each(function() {
            playercont++;
            $('#name' + playercont).val($(this).attr('username'));
            $(this).find("score").each(function() {
                scorecont++
                var tempo = $(this).attr('score')
                var tempo_final = new Date(Number(tempo))
                var milisec = tempo_final.getMilliseconds()
                var sec = tempo_final.getSeconds()
                var min = tempo_final.getMinutes()
                var hour = tempo_final.getHours()
                var score_final = hour + ":" + min + ":" + sec + ":" + milisec

                $('#score' + scorecont).val(score_final);
            });
        });
    });
}
