JavaScript - Dice Game
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"?> <!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Strict//EN" "http://www.w3.org/TR/xhtml1/DTD/xhtml1-strict.dtd"> <html xmlns="http://www.w3.org/1999/xhtml" xml:lang="en" lang="en"> <head> <title>Tärningsspel</title> <script type="text/javascript" language="javascript"> function showDice(imgNr) { if (imgNr == 1) var imgUrl = "1.gif"; else if (imgNr == 2) var imgUrl = "2.gif"; else if (imgNr == 3) var imgUrl = "3.gif"; else if (imgNr == 4) var imgUrl = "4.gif"; else if (imgNr == 5) var imgUrl = "5.gif"; else if (imgNr == 6) var imgUrl = "6.gif"; document.tarning1.src = imgUrl; document.tarning2.src = imgUrl; document.tarning3.src = imgUrl; } function randomInteger() { var randNumber = Math.random(); var randNumber = Math.floor(5*randNumber)+2; return randNumber; } function showRandomPict() { var imgNr = randomInteger(6); showDice(imgNr); var imgName = "tarning1" + imgNr; var imgName = "tarning2" + imgNr; var imgName = "tarning3" + imgNr; } function PlayAll(){ diceSwitch('tarning1', 'text1'); diceSwitch('tarning2', 'text2'); diceSwitch('tarning3', 'text3'); } function diceSwitch(randNumber,textRuta){ var randNumber = randomInteger(); } </script> </head> <body> <p><b>Tärning 1:</b><br /><span id="text1">1</span></p> <p><b>Tärning 2:</b><br /><span id="text2">2</span></p> <p><b>Tärning 3:</b><br /><span id="text3">3</span></p> <img src="1.gif" name="tarning1" onclick="javascript:diceSwitch('tarning1', 'text1')" /> <img src="2.gif" name="tarning2" onclick="javascript:diceSwitch('tarning2', 'text2')" /> <img src="3.gif" name="tarning3" onclick="javascript:diceSwitch('tarning3', 'text3')" /> <p><a href="javascript:PlayAll()">Spela alla!</a></p> </body> </html> Thank you! Similar Tutorialsguys im trying to make a dice game and i don't know nothing so can you guys help me with the code? This is what i am trying to do. i need help how to get started n stuff Something that will create a random number b/w 1 n 6 and decide if the user is a winner. He will win only if the #s are equal so i want a text box for the first number and text box for the second. a button to click to play the game(roll the dice) button to start over and reset all values textbox to display the # of tries(rolls) textbox 2 display the # of wins. Also i want toKeep track of the number of times the user rolls the dice and display this in the appropriate textbox and the number of times the user wins the game and display this in the appropriate textbox. Well my friend helped me with this but he made 2 player i only want one player and i want the number of tries and win the user wins if the #s are equal and i want a start over button that resets everything. Also the max number i want is 6 and only one roll the dice button but 2 textboxes so if you get same # you win it should appear in alert and text box for tries and wins. Also, i am gonna have 2 pics one for the first textbox the other for the second both of the pics are gonna be dice and i am gonna have 12 pics but only 2 appear at a time so if a guy gets 5 the dice with the #5 appears and the other text gets 4 the dice with the # 4 appears Code: <html> <HEAD> <SCRIPT LANGUAGE="JavaScript"> var die = 6; var dice = 2; var ary=[]; function dice_roll(die, dice,nu) { var txt=document.form.text; for (var roll=0,loop=0; loop < dice; loop++) { roll = roll + Math.round(Math.random() * die) % die + 1; } if (ary.length==0&&nu==0){ txt[0].value =ary[0]= roll; txt[1].value = 0; } if (ary.length==1&&nu==1){ txt[1].value = ary[1]= roll; if (ary[0]==ary[1]){ alert('Draw'); } else if (ary[0]>ary[1]){ alert('Player 1 Wins'); } else { alert('Player 2 Wins'); } ary=[]; } } // End --> </script> <body> <form name=form> <table border=2 cellpadding=5> <tr> <td colspan=2 align=middle>No. of sides/dice</td> </tr> <tr> <td valign=top align=middle> <p><input type=radio checked name=sides onClick="die = 6">6 Sided </td> <td valign=top align=middle> <p><input name=number type=radio onClick="dice = 2" checked> 2 </td> </tr> <tr> <td colspan=2 > Player 1 </td> </tr> <tr> <td align=middle colspan=4> <input type=button value="Roll Dice" name=button onClick="dice_roll(die, dice,0)"> <input type=text size=10 name=text value="0" disabled="disabled" > </td> </tr> <tr> <td colspan=2 > Player 2 </td> </tr> <tr> <td align=middle colspan=4> <input type=button value="Roll Dice" name=button onClick="dice_roll(die, dice,1)"> <input type=text size=10 name=text value="0" disabled="disabled" > </td> </tr> </table> </form> </center> </body> </html Hi, I'm trying to make a dice game, as well as making it two player. I need to be able to have a scoreboard displayed (eg. player 1 has won 7 times and player 2 has won 4) and I need to be able to prompt the user on if they want to play the game again. So far I have the following: Code: <html> <HEAD> <SCRIPT LANGUAGE="JavaScript"> <!-- Dice Game --> <!-- player 1 var die = 6; var dice = 2; var player1 = 0; var player2 = 0; function dice_roll(die, dice) { var roll = 0; for (loop=0; loop < dice; loop++) { roll = roll + Math.round(Math.random() * die) % die + 1; } document.form.text.value = roll; } player1 = roll; // End --> <!-- player 2 function dice_roll2(die, dice) { var roll = 0; for (loop=0; loop < dice; loop++) { roll = roll + Math.round(Math.random() * die) % die + 1; } document.form.text.value = roll; } player2 = roll; // End --> if player_1 = player_2 alert("DRAW!") else if player_1 > player_2 alert("Player 1 is the winner!") else if player_1 < player_2 alert("Player 2 is the winner!") </script> <body> <form name=form> <table border=2 cellpadding=5> <tr> <td colspan=2 align=middle>No. of sides/dice</td> </tr> <tr> <td valign=top align=middle> <p><input type=radio checked name=sides onClick="die = 6">6 Sided </td> <td valign=top align=middle> <p><input name=number type=radio onClick="dice = 2" checked> 2 </td> </tr> <tr> <td align=middle colspan=4> <input type=button value="Roll Dice" name=button onClick="dice_roll(die, dice)"> <input type=text size=10 name=text> </td> </tr> </table> </form> </center> </body> </html ^^ I basically just tried duplicating the original function that adds up the 'dice'. But it doesn't work, I've tried playing around with if/else statements etc to get it to display messages and so fourth, but I have failed. Any help would be appreciated. I only started javascript last week and my teacher isn't really helping explain lots of it. Thanks in advance. everything in this dice rolling game is fine until line 69 where i get TypeError:actuals[i] undefined. Any help would be appreciated. http://pastebin.com/bVmgMcbB Create a game where 6 dice are 'rolled' by you and 6 dice are 'rolled' by the player (simulated by the click of a button). Add up both rolls. The goal is to come as close to a score of 100 as possible, without passing 100. Have a STOP button to signify when you are ready to stop rolling and compute the winner. The highest score under 100 wins. Display the number of times you win and the number of times the computer wins using javascript. So far I have the following code, however, my dice images are not working(they display as little broken symbols when I run the game). The game itself is running just fine but I can't figure out how to get the game to do the "Add up both rolls" step and beyond. If anyone can help it would be much appreciated. Thanks.

I've worked with two other forums and a pay-by-minute guru to no avail. I am hopeful that the good folks here at CodingForums will be able to take this code the final distance. I'll try to be verbose without boring anyone. Summary: This code was written in 2005/2007 by "Wonder" at ProBoards. I teach a fourth grade game design and applied mathematics class to home-schoolers on a ProBoards forum. It is placed in the global footer of the forum to allow forum members to roll dice in their posts. The code was incomplete. I worked with "Jordan" at ProBoards to fix the parts that were incomplete. A problem with the code resulted. Primary resolution I'm seeking: Right now the code does everything I could possibly want. However, it is mistakenly reading double-digit numbers (XY) as X = sides of die and Y = a negative modifier. Once this issue is fixed, I can take the roller back to my students and they can game together. Secondary resolutions I'm seeking: (1) I've been told twice that the code should be "tabbed out." Not sure what that means but I guess it makes it less messy. (2) When clicking the "Add Tag" button the code generates, it automatically inserts [dice=6] into a forum post. Would love this to simply be [dice=X] The original code from "Wonder": Code: <style type="text/css"> .dicebg {background-color: FFFFFF;border:solid 2px #000000;} .dicefont {background-color: FFFFFF;color: 000000; font-weight:bold;} </style> <script> //Dice Rolls In Posts v1.1 updated 31 October 2008 //Copyright 4-23-2007 ~Wonder //May be reposted anywhere as long as this header remains in tact //Do you want the dice to line of horizontally(true) or vertically(false) diceAlignment=true; //Enter URL of the image you want to appear as the dice ubbc button UBBCdiceImage="http://img100.imageshack.us/img100/6118/diceicon9rx.gif"; //Enter the default # of sides defaultSides=6; //Enable dice in preview?

Once installed on a forum, it allows users to type the command [dice=X] where X is the number of sides for the single die they want to roll and it gives them a random result that's very attractive (a small white box with a black border and a bold, large result with smaller text below that reads: Xsides) and not "easy" to change/alter/cheat. To roll more than one die, you simply string the command like [dice=X][dice=X][dice=X][dice=X]. The code also allows for positive modifiers (bonuses) such as [dice=X+Y] where the result has the same compact, attractive format and the small text reads: Xsides+Y Wonder posted that his code would also allow negative modifiers (penalties) but, actually, no one seems to have ever tested that part... until September 2009 when along came pesky me. I went over to the ProBoards support forum because Wonder's code is included in their official database. I posted the problem and a user named Jordan tweaked the code several times, each time getting it closer to providing the correct result. The correct result being that when a user types the command [dice=X-Y] the result is the attractive box, the larger number above and the smaller text below that reads Xsides-Y (in addition to continuing to accept [dice=X] and [dice=X+Y] and offer the same format of results). Jordan's version of the code now does all this. But when I started testing it I realized that whenever a user types a command that gives the die double-digit sides (10, 12, 20, etc), the code now reads it like this: [dice=10] results in 1sides-0 or [dice=12] results in 1sides-2. So double-digit numbers are being read as the number of sides and a negative modifier *sigh* Very bad news. Jordan needed to pass on further work on the code because (understandably) it was taking too much time and it was "messy." Since I am not a coder myself, most JavaScript looks messy to me but I believe Jordan. I then took the code to a pay-by-minute help website but was gently told that the code was so messy that it would take too long to debug and it wouldn't be worth the charge since the roller is being used for a non-profit classroom project for my fourth graders. I thought that was very thoughtful... but I'm back at square one, really. I have attached everything I have: The very original code from Wonder (the one that doesn't read negative modifiers at all) and the latest from Jordan (that reads double-digits incorrectly). The only other cute/attractive thing about the code that I'll point out (so you don't see it in the code and wonder, "What the heck is that?" is: When you install the code into a forum, it adds a tiny die-shaped button to the Add Tags menu. Users can click the little thing and the code automatically inserts [dice=6] for them. Personally, this doesn't help my students and I would love it if the button just inserted [dice=X] but that's fine. *deep breath* Whew! That's about it. Thank you for putting up with my blather. I sincerely appreciate any help you can offer. I know your time is valuable and I've taken quite a bit just posting my full report... I just wanted to try to be verbose :) Jennifer 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! 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. 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
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.

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> </body> </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.

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 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. Hi every1! Got a task in university to make a memory game (card matching game).

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? 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; var NROWS; var NCOLS; var BRICKWIDTH; var BRICKHEIGHT; var PADDING; var y=4; window.addEventListener("load",init,false); //event for loading main func window.addEventListener("keydown",buttonpressed,false); //event for checking if button is pressed window.addEventListener("keyup",buttonreleased,false); //event to check if button is released 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 NROWS = 5; NCOLS = 3; BRICKWIDTH = (WIDTH/NCOLS) - 1; BRICKHEIGHT = 15; PADDING = 1; bricks = new Array(NROWS); for(i=0; i<NROWS; i++){ bricks[i] = new Array(NCOLS); for(j=0; j<NCOLS; j++){ bricks[i][j] = 1; } } } function mousemoved(e){ //function that enables movement of paddle with mouse if(e.pageX > mouseXmin && e.pageX < mouseXmax) recx = e.pageX ;//- mouseXmin; <---why would you need that?Movement is bugyy! FIX:) } function buttonpressed(e){ //to check if any of keyboard arrow buttons are pressed if(e.which==37) { leftDown = true; } if(e.which==39) { rightDown = true; } if(e.which==40) { upDown = true; } if(e.which==38) { downDown = true; } } function buttonreleased(e){ //function to check if button up,down,left or right is released if(e.which==37) { leftDown = false; } if(e.which==39) { rightDown = false; } if(e.which==40) { upDown = false; } if(e.which==38) { downDown = false; } } function clear(){ //function to clear the stage ctx.clearRect(0,0,800,600); } function circle(x,y,r){ //function to draw circle shape ctx.beginPath(); ctx.arc(x,y,r,0,Math.PI*2,true); ctx.closePath(); ctx.fill(); } function rect(x,y,w,h){ //function to draw rectangle shape ctx.beginPath(); ctx.rect(x,y,w,h); ctx.closePath(); ctx.fill(); } function checkforCoallision(){ //checks for borders of main canvas and if ball hits the paddle if(ballx + dx > WIDTH-ballr || ballx + dx < ballr) dx = -dx; if(bally + dy < ballr ) dy = -dy; else if (bally + dy > HEIGHT - ballr){ if(ballx + ballr > recx && ballx + ballr < recx + recw) dy = -dy; else {clearInterval(intervalId); alert('Game Over,Baby!');} bounce();} } function draw(){ //function that draws the desired shapes and animates them clear(); //clears the main canvas,so the animation would look smooth checkforCoallision(); //checks for borders of main canvas and if ball hits the paddle if(leftDown) recx -= rx; //enables movement of paddle right and left if(rightDown) recx += rx; for(i=0; i<NROWS; i++){ //drawing bricks for(j=0; j<NCOLS; j++){ if(bricks[i][j] == 1) { //checking if brick exists rect(j * (BRICKWIDTH+PADDING)+PADDING,i * (BRICKHEIGHT+PADDING) + PADDING, BRICKWIDTH, BRICKHEIGHT) } } } //have we hit a brick? rowheight = BRICKHEIGHT + PADDING; colwidth = BRICKWIDTH + PADDING; row = Math.floor(bally/rowheight); col = Math.floor(ballx/colwidth); //if so, reverse the ball and mark the brick as broken if (bally < NROWS * rowheight && row >= 0 && col >= 0 && bricks[row][col] == 1) { dy = -dy; bricks[row][col] = 0; } circle(ballx,bally,ballr); rect(recx,recy,recw,rech); ballx += dx; bally += dy; } /* function init(){ ctx = document.getElementById('can').getContext('2d'); WIDTH = document.getElementById('can').offsetWidth ; //gets the width of main canvas HEIGHT = document.getElementById('can').offsetHeight ; //gets the height of main canvastto recx = WIDTH / 2; //setting the coord x of a paddle recy = HEIGHT - rech; //setting the coord y of a paddle init_mouse(); init_bricks(); intervalId = setInterval(draw,10); //calls draw func on desired interval,which is represented by number next to it return intervalId; } */ function delay() { if(y<=0) { document.getElementById('content2').innerHTML = "<canvas id='can' width='300' height='300'>This text is displayed if your browser does not support HTML5 Canvas.</canvas>"; ctx = document.getElementById('can').getContext('2d'); WIDTH = document.getElementById('can').offsetWidth ; //gets the width of main canvas HEIGHT = document.getElementById('can').offsetHeight ; //gets the height of main canvastto recx = WIDTH / 2; //setting the coord x of a paddle recy = HEIGHT - rech; //setting the coord y of a paddle init_mouse(); init_bricks(); intervalId = setInterval(draw,10); //calls draw func on desired interval,which is represented by number next to it return intervalId; } else { Object = document.getElementById('content2'); y = y - 1; Object.innerHTML = "<div style='text-align:center;width:25em;margin: 0px auto;height:100px;position:absolute;top:50%;margin-top:-50px;'>"+y+"</div>"; setTimeout("delay()", 1000);} } 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++; } } } } 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)?
