Been working on an easel game tutorial that involves an animated character going across the screen and avoiding crates falling from above. I've followed the code in the tutorial exactly but no joy;nothing seems to be loading (including images which are mapped correctly). No errors regarding syntax seem to occur so not sure what the problem is. It's a fair bit of code so totally understand if no-one has the time but just in case here it is ;
Site Page code (ill post the individual JavaScript file codes if anyone is interested;

I noticed that you try to initialize the EaselJS-objects without a namespace:
stage = new Stage(canvas);
But since 0.5.0 you have to use the createjs-namespace(or map the namespace to window before you do anything)
So what you would have to do now will ALL easelJS-classes is to add a createjs. before them when you are creating a new instance like this:
stage = new createjs.Stage(canvas);
Not sure if that's everything, but it's a start, hope this helps.
You can read more on CreateJS namepsacing here: https://github.com/CreateJS/EaselJS/blob/master/README_CREATEJS_NAMESPACE.txt

I want something like this site , look at mouse background in header section:

when i check page source i found this:

Take a look at source code and identify which JS plugins are being used.

Problem
Hello, I am creating a game and am stuck on how to get a timer on the canvas. I am aware that there are plenty of questions on Stackoverflow already about this topic.
Question
Could someone please tell me why my code does not work.
Code
var game = create_game();
game.init();
function create_game() {
debugger;
var level = 1;
var projectiles_per_level = 1;
var min_speed_per_level = 1;
var max_speed_per_level = 2;
var last_projectile_time = 0;
var next_projectile_time = 0;
var width = 600;
var height = 500;
var delay = 1000;
var item_width = 30;
var item_height = 30;
var total_projectiles = 0;
var projectile_img = new Image();
var projectile_w = 30;
var projectile_h = 30;
var player_img = new Image();
var background_img = new Image();
var c, ctx;
var projectiles = [];
var player = {
x: 200,
y: 400,
score: 0
};
function init() {
background_img.src = "background.png";
projectile_img.src = "projectile.png";
player_img.src = "player.png";
level = 1;
total_projectiles = 0;
projectiles = [];
c = document.getElementById("c");
ctx = c.getContext("2d");
ctx.fillStyle = "#410b11";
ctx.fillRect(0, 0, 500, 600);
c.addEventListener("mousemove", function (e) {
//moving over the canvas.
var bounding_box = c.getBoundingClientRect();
player.x = (e.clientX - bounding_box.left) * (c.width / bounding_box.width) - player_img.width / 2;
}, false);
setupProjectiles();
requestAnimationFrame(tick);
}
function tick() {
Most of game logic is here, I deleted as it I dont believe it helped keeping it in.
var i;
var projectile;
var dateNow = Date.now();
c.width = c.width;
ctx.drawImage(background_img, 0, 0);
for (i = 0; i < projectiles.length; i++) {
projectile = projectiles[i];
if (dateNow > projectile.delay) {
projectile.y += projectile.v;
if (collision(projectile)) {
initProjectile(i);
player.score++;
} else if (projectile.y > height) {
initProjectile(i);
} else {
ctx.drawImage(projectile_img, projectile.x, projectile.y);
}
}
}
ctx.font = "bold 24px sans-serif";
ctx.fillStyle = "#d1c09c";
ctx.fillText(player.score, c.width - 50, 50);
ctx.fillText("Level: " + level, 20, 50);
ctx.drawImage(player_img, player.x, player.y);
maybeIncreaseDifficulty();
requestAnimationFrame(tick);
This is where i was going to put my code for the timer:
var startTime;
function drawElapsedTime(){
var elapsed=parseInt((new Date() - startTime)/1000);
ctx.beginPath();
ctx.fillStyle="red";
ctx.font="bold 24px sans-serif";
g.fillText(elapsed+" secs", 75,25);
g.restore();
}
}
return {
init: init
};
}
I hope this makes sense, sorry for the overload of code.
From what I see, you might have forgotten to initialize your startTime variable.
ParseInt() of something undefined returns NaN.
Make sure to assign a value to it and that this value is accessible in the scope of your drawElapsedTime() function.
Im trying to make a collision detection "program" in Three.js (WEBGL library).
However, Im getting an error "cannot call method multiplyvector3 of undefined".
Can anyone tell me what Im doing wrong?
The function for collision detection I just implemented, is:
function animate() {
requestAnimationFrame(animate);
render();
for (var vertexIndex = 0; geometries[0].vertices.length; vertexIndex++)
{
var localVertex = geometries[0].vertices[vertexIndex].clone();
var globalVertex = geometries[0].matrix.multiplyVector3(localVertex);
var directionVector = globalVertex.subSelf(meshes[5].position);
var ray = new THREE.Ray( meshes[5].position, directionVector.clone().normalize() );
var collisionResults = ray.intersectObjects( meshes);
if ( collisionResults.length > 0 && collisionResults[0].distance < directionVector.length() )
{
}
else {
meshes[5].position.y -= 0.15;
meshes[5].rotation.z -= 0.15;
}
}
}

Thank you!
for (var vertexIndex = 0; geometries[0].vertices.length; vertexIndex++)
should be

I got the following RequestAnimationframe function from http://my.opera.com/emoller/blog/2011/12/20/requestanimationframe-for-smart-er-animating
I am trying to use it. But not sure how to call it and use it. Can someone give me a simple example. I am new to this html5 animation thing so you can understand..
I will really appreciate any help! The function is below..
(function() {
var lastTime = 0;
var vendors = ['ms', 'moz', 'webkit', 'o'];
for(var x = 0; x < vendors.length && !window.requestAnimationFrame; ++x) {
window.requestAnimationFrame = window[vendors[x]+'RequestAnimationFrame'];
window.cancelRequestAnimationFrame = window[vendors[x]+
'CancelRequestAnimationFrame'];
}
if (!window.requestAnimationFrame)
window.requestAnimationFrame = function(callback, element) {
var currTime = new Date().getTime();
var timeToCall = Math.max(0, 16 - (currTime - lastTime));
var id = window.setTimeout(function() { callback(currTime + timeToCall); },
timeToCall);
lastTime = currTime + timeToCall;
return id;
};
if (!window.cancelAnimationFrame)
window.cancelAnimationFrame = function(id) {
clearTimeout(id);
};
}())
Just paste that code into your JS or in its own file and put this inside of your rendering function at the very bottom.
requestAnimationFrame(yourrenderingfunction);
Live Demo
// requestAnimationFrame shim
(function() {
var lastTime = 0;
var vendors = ['ms', 'moz', 'webkit', 'o'];

Sorry if this question is a bit vague, but this has been driving me nuts recently. It's nothing too complicated, but all I want to do is have the variable 'targetVariable' be affected by a formula. The actual problem lies in the fact that the referenced variable, being 'masterVolume' in this case, is not getting affected by the formula, but rather 'targetVariable' instead. I run the 'makeSlider' function at the bottom of the script. Here's the code:
var masterVolume:Number = 0;
var panning:Number = 0;

Okay, so I studied the Object class and found out that I could reference the variable by making it an object in the function. Here's the updated, working script:
var panning:Number = 0;
var masterVolume:Number = 0;
function makeSlider(sliderType, barType, soundType, hitBoxScale:Number, X, Y, targetVariable) {
var reference:Object = { targetVariable: 0 };
var slider:MovieClip = new sliderType;
var newBar:MovieClip = new barType;
addChild(newBar);
newBar.x = X;
newBar.y = Y;
addChild(slider);
slider.x = X;
slider.y = Y;
var dragging:Boolean = false;
stage.addEventListener(Event.ENTER_FRAME, updateSlider);
function updateSlider(e:Event):void {
panning = (mouseX/(stage.stageWidth/2))-1;
reference.targetVariable = (slider.x-newBar.x)/newBar.width;
if (dragging == true && mouseX >= newBar.x && mouseX <= (newBar.x + newBar.width)) {
slider.x = mouseX;
}
if (reference.targetVariable <= 0.01) {
output.text = ("None");
}
if (reference.targetVariable >= 0.99) {
output.text = ("Max");
}
if (reference.targetVariable > 0.01 && reference.targetVariable < 0.99) {
output.text = (Math.round((reference.targetVariable*100))+"%").toString();
}
}
stage.addEventListener(MouseEvent.MOUSE_DOWN, beginDrag);
function beginDrag(e:MouseEvent):void {
if (mouseY >= newBar.y-hitBoxScale && mouseY <= (newBar.y + newBar.height)+hitBoxScale) {
dragging = true;
}
}
slider.addEventListener(MouseEvent.MOUSE_DOWN, beginDragFromSlider);
function beginDragFromSlider(e:MouseEvent):void {
dragging = true;
}
stage.addEventListener(MouseEvent.MOUSE_UP, endDrag);
function endDrag(e:MouseEvent):void {
if (dragging == true) {
playSound(soundType, reference.targetVariable, 0);
}
dragging = false;
}
stage.addEventListener(MouseEvent.MOUSE_DOWN, make);
function make(e:MouseEvent):void {
if (dragging == false) {
playSound(test, reference.targetVariable, panning);
}
}
}
function playSound(target, intensity:Number, pan:Number) {
var sound:Sound = new target();
var transformer:SoundTransform = new SoundTransform(intensity, pan);
var channel:SoundChannel = new SoundChannel();
channel=sound.play();
channel.soundTransform = transformer;
}
makeSlider(defaultSlider, defaultBar, volumeIndicator, 10, 134, 211, masterVolume);
