JavaScript - Need Help With My Code For A Game Of Craps
Similar TutorialsHi, I am working on a simple javascript craps game program. I need some advice since it won't display who the winner is, keep tally of who wins/loses, and the number of total games played. After using the error console there's an error with document.forms[0].thrower.value not being defined. Can anyone help me with this?

First you toss the pair of dice. If the sum of the dice is 7 or 11, you win the game. If the sum is 2, 3, or 12, the house wins. Otherwise, the sum is designated as the "point," to be matched by another toss. So if neither player has won on the first toss, then the dice are tossed repeatedly until either the point or a 7 comes up. If a 7 comes up first, the house wins. Otherwise, you win when the point comes up. </body> </html> Hi I am using httpXmlRequest object to call a xml web service. In order to successfully perform a task there are couple steps need to happen. 1 you have to request for a session (cookie) 2 with the cookie, we need to authenticate with the server 3 then perform other actions snippet of my code looks something like this. Basically here i am trying to get the cookie, login and then logout once logged in. function connect() { document.myForm.elements['myTextArea'].value += "connecting to teh server.\n"; try { xhttp.open("GET",urlStr + commonInfoParam, true); xhttp.send(); xmlDoc = xhttp.responseXML; xmlDoc.onreadystatechange = function () { if(xmlDoc.readyState == 4) { var resultsTag = null; resultsTag = xmlDoc.getElementsByTagName("results"); if(resultsTag != null) { for(i=0;i<resultsTag.length;i++) { var commonTag = resultsTag[i].getElementsByTagName("common"); for(j=0;j<commonTag.length; j++) { cookie = commonTag[j].getElementsByTagName("cookie")[0].childNodes[0].nodeValue; break; } } } if(cookie != null) { document.myForm.elements['myTextArea'].value += "cookie found: " + cookie + "\n"; login(); } } }; } catch(e) { document.myForm.elements['myTextArea'].value += "Exception occurred at connect: " + e.message + "\n"; } } function login() { var loginRequestURL = "http://testconnect.com/api/xml?action=login&login=" + username+ "&password=" + password + "&session=" + cookie; try { xhttp.open("GET", loginRequestURL, true); xhttp.send(); xmlDoc = xhttp.responseXML; xmlDoc.onreadystatechange = function () { alert('in loginResponseHandler'); if(xmlDoc.readyState == 4) { try { loginStatus = xmlDoc.documentElement.childNodes[0].attributes.getNamedItem("code").nodeValue; if(loginStatus == 'ok') { alert("login is good: " + loginStatus); logout(); } else { } } catch(e) {} } }; } catch(e) { } } function logout() { alert("in logout"); try { xhttp.open("GET", logoutRequestURL + cookie, true); xhttp.send(); xmlDoc = xhttp.responseXML; xmlDoc.onreadystatechange = function () { alert("in logoutResponseHandler"); if(xmlDoc.readyState == 4) { try { status = xmlDoc.documentElement.childNodes[0].attributes.getNamedItem("code").nodeValue; if(status == 'ok') { alert(status); } } catch(e) {} } }; } catch(e) {} } so when I run my code in the browser, all my alert stages give me proper message as expected. But at the final alert, it hangs. I just could not figvure out what am i doing wrong. can any one pin point this out for me please? Thanks in advance. KM Basically, I have a Simon Says game with very simple functions but I added an image map with buttons that I now want to use, rather than a table with images as buttons. The problem is, now I can't get the game to work with the image map. Can anyone help me?
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. sorry this post is duplicated, the original post:http://www.codingforums.com/showthread.php?t=261488
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! I am creating a guessing word game and when the user types in a guess a pop-up tells the user how many letters the user got right to the actual answer. My problem is I can't seem to display the number of letters the user guessed right. This is what the function looks like: Code: function guessing()
{
words = "album";
guess = document.getElementById("txt1").value;
answer = document.getElementById("result").value = parseInt();
alert("You have " + answer + " matches");
used = false;
for(i = 0; i<=guess.length; i++)
{
for(j = 0; j<=answer.length; j++)
if(!used[j] && guess[i] == words)
{
alert("Congradulations! You got it!");
used[j] = true;
count++;
break;
}
else
{
count = 5;
while(count > 5)
{
alert("Sorry, that's game over!");
count++;
}
}
}

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;

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 Hi guys I need some help with a 2d game that i am making. i am almost done i need only a loading screen but its not working i got this javascript file thats getting an error about : assetsloader is not defined.

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). 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.
Can someone guide me to what I am doing wrong. My book does not show how to do this. This is what I have to far.I am just getting more and more confused. I am suppose to have a button there asking write a timeout that asks users if they want to stop the game if they do not press the Guess button within 10 seconds. 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)?

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>

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? 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>

If you load this onto a webpage you'll see what i'm trying to do. I tried deleting the rest of the code to keep the size of the code down. 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. |
