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!

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). 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++;
}
}
}
}
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 Hey guys I need help on making the images on this game show up. Im not sure how to get the card images to load when hitting the deal button. Code: <html>

Hi everyone. Right now I'm doing a guessing game assignment for my class. I'm new to the forums so sorry if copy/pasting code into the thread here isn't the right thing to do. I have ran firebug a few times on this code and for some reason the variable "Football" is the only answer that is declared true.

Hello, this is my first post here, but I'm having some trouble figuring out what I messed up on my code I'm making a Javascript game of Hangman for one of my classes and I originally had the input as a text box where you physically type in the letter and if it was wrong, it would draw the next sequence of the hangman picture and place the letter in another text box as a "Used Letters," or if you're right, it would place the letter you chose in the box for the word you're guessing. However, I decided that instead of doing that, I wanted to make it more visually appealing and add buttons with the letters on them instead. As you can see in the code which is down-loadable here (the one with the _2 is the one I'm currently using, but the original is supplied as well), the buttons register for the picture changing, but do not register for the "Used Letters" field or for filling in the actual word. One of the button's values is also replaced by "undefined" after each click of another button and I'm not really sure why If anyone could take a look at my code and see if you can figure out what the deal is, that'd be awesome! Hi there, On this website: http://www.lutanho.net/stroke/online.html it's allowed to "copy the games to your PC and play them offline". That's nice but how do I do that? I've tried to download/copy the game "WordGrid" to my PC but it didn't work. Help would be appreciated. Thanks in advance........... Hey all, I'm trying to code a javascript game for my final project as a mini game within an interactive website, but I'm having some problems since I don't know javascript. It's supposed to be a piano game with a specific pattern to one song (so the game has the same pattern everytime) and I can't get it to work. This is my code right now (I started working with a code I found online). I'm really struggling, if anyone has any ideas on what I'm doing wrong it would be greatly appreciated! Code:

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>

if anyone has any help id be grateful or if anyone has any ideas on how to approach this differently. thanks in advance please excuse the code its a little messy atm. sorry Hi, well i searched at google and was not exactly able to find what i was looking for, i am looking for a script the shows by logo while loading the game at back end, shows loading percentage or bar representing how game is loaded and then makes the my logo disappear once the game is loaded e-g like this site has used http://www.gamegape.com/en-2095-elemental-battles.html if some thing like this is not available can someone atleast tell me how this site has done it, so we could copy it from them ^_^ Hi, i wonder if anybody got a link to a tutorial for a javascript yahtzee game?
hey guys i'm making a lunar lander game using javascript.i want the player to land the spaceship on a black line i've drawn. but i have problems getting it right.when the player lands it properly in the line i want it to display a dialogue box which says u landed it perfectly.but the problem is even if i land it outside the line it gives me that message.so after spending sometime with it i figured out that my if statement is not working properly.it doesn't take the value from my x axis and only considers the value from my y axis.for eg lets say i drew the line from 560px to 600px on the x axis and its located at 700px on the y axis and this is my if statement if((TopPos>695)&&(rightPos>560)&&(rightPos<600)) { alert('you landed perfectly') } this is supposed to work but if i go above 600px but still maintains the height above 695 it says i have won.i have included the code could some point me out where i'm making the mistake thank you .

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.

Hi, I'm doing a project for college where i have create a game in which images must be dragged-and-dropped into a certain order. The game should: * Be web-based, using client-side JavaScript * Include At LEAST FIVE moveable images * Randomise the positions of the images at start-up * Check the positions of the images and notify the user when they are in the correct order * Record and display the time taken to sort the images All of these requirements are working, i have div tags set up with borders around them, so that the user knows where to place the images. The thing i would like to do is when an image is dragged say within 20px of a div that the image snaps to the div...can anybody suggest a way to do this or perhaps a code suggestion. Code: <html>

Thanks very much in advance i have a simple collision if statement in the main interval in a javascript game. The problem is, it only sometime works, as in i have to shoot at zombies multiple times for them to disappear, when it should only take 1 bullet. i have arrays for the players bullets x and y values, and 5 zombies x and y values(4 total arrays). The collision code is at the bottom of the main() function. here is the code: Code: var missed = 0;
var score = 0;
var on = 1;
var bulletx = [];
var bullety = [];
var zombiex = [700,600,800,1000,900];
var zombiey = [0,100,300,200,50];
function draw(image, x, y){
var canvas = document.getElementById("game");
var context = canvas.getContext("2d");
var imageObj = new Image();
imageObj.onload = function() {
context.drawImage(imageObj, x, y);
};
imageObj.src = image;
}
document.onkeydown = checkKey;
function checkKey(e) {
if(on === 1){
if(on === 1){
e = e || window.event;
if (e.keyCode == '40') {
down();
}else if (e.keyCode == '38') {
up();
}else if(e.keyCode == '32'){
bullety.push(y+50);
bulletx.push(100);
score = score - 1;
}
}
}
}
var y = 300;
function down(){
y = y+50;
draw("player.png", 0, y);
}
function up(){
y = y-50;
draw("player.png", 0, y);
}
draw("player.png",0,y);
function main(){
draw("background.png",0,0);
draw("player.png",0,y);
for(i = 0; i < 5; i++){
draw("zombie.png",zombiex[i],zombiey[i]);
zombiex[i] = zombiex[i] - 5;
if(zombiex[i] < -100){
zombiex[i] = 600;
zombiey[i] = Math.random()*450
missed = missed+1;
}
}
if(missed === 5){
clearInterval(mainint);
alert("5 zombies passed you, and America has fallen");
alert("sco "+score);
on = 0;
}
for(i = 0; i < bulletx.length; i++){
draw("background.png",0,0);
draw("bullet.png",bulletx[i],bullety[i]);
bulletx[i] = bulletx[i]+30;
if(bulletx[i] > 700){
bulletx.splice(i,1);
bullety.splice(i,1);
}
if(bulletx[i] > zombiex[i] && bullety[i] > zombiey[i]-20 && bullety[i] < zombiey[i]+70){
zombiex[i] = 600;
zombiey[i] = Math.random()*450
score = score + 10;
}
}
}
var mainint = setInterval(function(){main();}, 50);
