JavaScript - Game Problem
Hi,
i made a game,where you controll a paddle to bounce back a ball and it hits the bricks on top. The problem is that my eventhandlers don't work after i've added delay function,to make a counter(counting from 3 to 1 before game starts). Any tips?Is it scope problem? Code: var ballx = 100;
var bally = 100; //coord x and y,radius of a ball
var ballr = 10;
var recx;
var recy; //coord x and y,width and height of a paddle
var recw = 100;
var rech = 15;
var dx = 2; //x coord step for animated movement of ball
var dy = 2; //y coord step for animated movement of ball
var rx = 5; //x coord step for animated movement of paddle
var WIDTH; //width of main canvas
var HEIGHT; //height of main canvas
var ctx; //drawn shape
var leftDown = false;
var rightDown = false; //keyboard arrow buttons
var upDown = false;
var downDown = false;
var mouseXmin;
var mouseXmax;
var intervalId;
var bricks;

window.addEventListener("mousemove",mousemoved,false); //event for controlling paddle with mouse movement
function init_mouse(){ //initialize coord for mouse movement
mouseXmin = document.getElementById('can').offsetLeft;
mouseXmax = mouseXmin + (WIDTH-recw); //doesn't work that pretty...check?
}
function init_bricks(){ //initialize bricks

I have on my website ( www.nieeli.com/game/ ) the index.html, then a folder scripts with jquery.js and game.js in.. Could anyone help me Oh, just noticed there is a Jquery help section... Sorry Okay I'm writing a JavaScript application that would prompt the user for a number between 0 and 2, generate a random number for the computer, then take that input and display two images (in this case two hands making rock, paper, or scissor symbols at each other) using an array, and displaying text indicating a win, draw, or loss. I'm having a lot of problems getting this to work as I am new to JavaScript and am wondering if anyone could help me fix this problem. I just want the input from the prompt AND the random number to translate to what in the array should be displayed and what text is then shown at the bottom. Any comments/advice/help is greatly appreciated! By the way for some reason it doesn't let the letters H T M L show up together so that is where the ellipses are showing up! Code: <script type = "text/javascript">
selection = prompt("Enter 0 for rock, 1 for paper, and 2 for scissors")
userChoice = parseInt(selection)
arrayHolder = new Array();
arrayHolder[0] = "rock.jpg";
arrayHolder[1] = "paper.jpg";
arrayHolder[2] = "scissors.jpg";
compchoice = Math.floor(Math.random()*arrayHolder.length)
function playGame(idholder1)
{
document.images["userpic"].src = arrayHolder[userchoice];
document.images["comppic"].src = arrayHolder[compchoice];
if (userChoice == 0 && compchoice == 0)
{
document.getElementbyId(idholder1).innerHTML = "DRAW!"
}
else if (userChoice == 0 && compchoice == 1)
{
document.getElementbyId(idholder1).innerHTML = "Paper beats Rock, you lose!"
}
else if (userChoice == 0 && compchoice == 2)
{
document.getElementbyId(idholder1).innerHTML = "Rock beats Scissors, you win!"

This is a simple basic game i want to make. Its a "What Am I" Riddle... The questions is (In HTML which i already know): I'm as light as a feather but no man can hold me for long. What am I? the answer is: Your Breath. (This is where the JAVASCRIPT comes in) Lets say they guess a rock, have a pop up say: Wrong Answer. Please try again. Lets say they guess Your breath -OR- Breath, have a pop up say: Correct! I want a text field where you can enter your answer, and if they choose ANYTHING but the 2 correct answers above, it will display please try again. Can anyone code this please? Thanks for reading. Ok so i want to work on an EASY basic game. As simple as Guess what number... But there are some twist... Ok So here is my example... (HTML, i know this.)I'm Guessing a number 1-99. What is it? (java) Lets say its 66 and they guess 53, have the text rusult be in a pop up window be: Too low! (java) Lets say they guess 78, have the text rusult be in a pop up window be: Too high! (java) Lets say they guess 100+, have the text rusult be in a pop up window be: Out of range! (java)But lets say they guess 66, have a text result be in a pop up window be: You've won! (java) I want a text field where you can enter your answer, and it will do the actions above. Can anyone code this? Thanks for reading! I have a game page on my site and I am trying to protect direct access to it by .htaccess .htpasswd but is not accepting user name and password? .htaccess: AuthUserFile /home/vhosts/kandcoentertainment.freetzi.com/.htpasswd AuthType Basic AuthName "game1" <Files "cookietest.html"> Require valid-user </Files> .htpasswd test:8888 Any suggestions on why it is not working? What I would like to do is have apay and play once setup but as I am a novice and dont have a clue HELP PLEASE!!! What I have been told is - protect the files, add a client side cookie to game page then upon url payment return validate cookie giving single access and when played the user cannot replay by refresh or just typing in url because cookie expired ? I have tried to write the scripts up with no success. Hello all, * I'm very new to javascript and working on a quiz game. Theres a set of code im working on but i need help, and greatly appreciate any help. * After every questions, there is a tick or wrong animation/image that should pop over the answer card. I created the gif file one for a tick and one for a wrong: http://www.freeimagehosting.net/cqn91 http://www.freeimagehosting.net/v74v6 *By right the user should not be able to click on the answer cards anymore after finishing the quiz. For now the score keeps going up although the quiz is done. And after the quiz is done, a button should direct the user to the DetailedResult page, instead of the popup. *How to change the popup into a Html(DetailedResult) page, and instead of a text eg.(resent.jpg), how can I make the real image show, and if the qn is correct, how can I place a tick and if the qn is wrong how can I place a wrong image. Ive created both images. tick image==>http://i1069.photobucket.com/albums/...ttica/tick.jpg wrong image==>http://i1069.photobucket.com/albums/...ca/wrong-1.jpg *Suppose at the bottom of the html page, should have a button for the user to retry only wrong answers. *And how do i keep updating the user score for each attempt he tries on the table. Below are a set of code i'm working on, and another set of Html layout(DetailedResult) which i intend to achieve. Code: <!DOCTYPE HTML>

They are suppose to pick a number between 1-100. <!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Strict//EN" "http://www.w3.org/TR/xhtml1/DTD/xhtml1-strict.dtd"> <html> <head> <meta http-equiv="content-type" content="text/html; charset=utf-8" /> <title>Guessing Game</title> <script type="text/javascript"> while (runAgain == 'y' || runAgain == 'Y') { guessedNumber = reader.readDouble("Please pick a number between 1 and 100: "); while (guessedNumber != randomNumber) { if (guessedNumber < randomNumber) System.out.println("Too low!\nGuess again!"); else if (guessedNumber > randomNumber) System.out.println("Too high\nGuess again!"); else if (guessedNumber == randomNumber) System.out.println("You got it!"); } runAgain = reader.readChar("Play again (y/n)?

Hi! I am studying webdesign and we also go through a chapter of javascript-programming. Our first assignment is to create a dice game. I have written a code and in the beginning it worked, except that all the dices showed the same random number. I tried to fix that and now I do not know what I have done! In the game, you shall click on a link and the three dices will show random numbers. Here is my code: Code: <?xml version="1.0" encoding="UTF-8"?>

Thank you! How hard would it be to make a 2d game similar to super smash bros? Basically I want to have a scrolling position (instead of a static image, where the background is always the same) where when the user moves his character object, the area of vision moves with him. Also, will it work with using keyboard keys? I have to integrate it into a database and I know quite a bit of javascript so I am hoping it is possible. Thanks! Max Hello, I am trying to create a clock for my video game. I need to begin the clock at zero and count while the game is going. I need to have the clock count in standard minutes and seconds but not be based on the actual time of day. I am coding in javascript for an applet.
What I'm trying to achieve is it initialises a number between 1-2000 randomly. When the submit button is clicked it simply returns if the number that is in putted is higher or lower than the randomly initialised number. External JavaScript: Html Code: <html>
<head>
<script type="text/javascript" src="jsscri.js"></script>
</head>
<body onload="initialisation ()">
<form name="exampleform">
<h3>
Number: <input name="number" type="text"
onchange='checkNumber( this.value );'>
</h3>
<p>
<input name="submit" type="button" value="Guess"
onclick= 'checkValue()';/>
</p>

so the problem is, that I can just click 2 times on one card and it will look like a coincidence. My second problem is that when I have a real coincidence, I can still click on that card (by "real coincidence" i mean two same pics. so when i find them, they have to be not active, and when im clicking on them, they should just simply do nothing.). Can someone help me? Hello everyone. I have a tic tac toe game I am working on and I managed to make it so you can place X's and O's respectively. My next problem is making a win condition so it checks to see if the X's won the game or the O's did. Here is what I have so far. Edit fiddle - JSFiddle What I am basically thinking is that when you are clicking I want whatever letter it is that is placed to be saved and then I can check to see if all 3 are equal to that letter. It is a bit hard to explain. Essentially I want to make a win condition. If anyone could throw some assistance my way that would be great. I know for sure it requires a lot of checks because there are so many different ways of winning, I just need to know that initial one. Thank you very much.

There is exactly one reference to assetLoader (without the 's') and that is to add a progress() function to every occurrence of the assetLoader object that you haven't defined (at least not in the code you posted).

Absolutely nothing happens when I click on the button, and I know NOTHING about Java. Need serious help! The user is supposed to arbitrarily type a number (1-5) and see if it's the same one that JavaScript generates. The function "secretNum" is supposed to be a global variable, but I don't have a clue as to what that means. Anyways, an alert should pop up saying either congrats or try again. Code: <html>
<head>
<title>Guessing Game</title>
<script type="text/javascript">
function setUp ()
{
secretNum = 1+Math.floor(5*Math.random());
alert = (secretNum);
}
function checkGuess ()
{
userGuess = document.IfForm.guessBox.value;
userGuess = parseFloat(userGuess);
// get value from text box
if (secretNum == userGuess)
{alert ("Correct!");}
else
{alert ("Sorry, Try Again");}
}
</script>
</head>
<body style="text-align:center" onLoad="setUp();">
<h2>Guess the Number From 1 to 5</h2>
<form name="IfForm">
Enter Your Guess:
<input type="text" size="5" name="guessBox" value="" />
<br />
