PHP, JQUERY Tic Tac Toe

[xScence]

Hi all. Im trying to figure out how can i make tic tac toe with php and jquery and AI. If anyone can give me some examples,logic i'll be happy. Thanks to all.

Er, you wouldn't need php or jquery for that, you could write it all in javascript, unless you had some desire to log win/loss results. Hell, you could even do that for one player locally.

 

Figure out how to store the data (hint: arrays), then figure out the test cases. It's not hard, since there's no such thing as winning in tic-tac-toe, only not losing.

It must be on php and ajax / jquery i know i can only wtite it on js but it need to be php + ajax / jquery

[jren207]

So is this a game of Tic Tac Toe played over the Internet between two computers?

I guess you'd need to POST the moves of Player 1 using AJAX to a PHP script (adding this to a DB), then Player 2's browser would be polling the server using another PHP script (querying the DB) and an AJAX GET request to update the game on their end, and vice-versa?

Seeing as it MUST be PHP/JQuery, can I ask, honestly - are you asking for homework help?

sounds like some work i got set a long time ago ;) haha :P you need to be more specific... what do you want the game to do.

[xScence]

Well when i click somewhere AI to click too after my move. Me click -> AI click -> Me Click -> AI click and so on till some one wins or its ties. I just need some logic and examples thats all.

ok well personally I would store all the moves in a PHP array ..but as for the "AI" ...its a loose term its actually simulated AI ....it gives the impression of intelligence and while you may or may have not known that is irrelevant what you have to remember is not matter what... you are going to have to program all its moves.. whether you right a mathmatical algorithm or if you simply write a database full of possible outcomes 

 

I would have to sit down and think about it but personal I would go with a lengthy algo ...you can write a list of functions but the main thing you need to do is make it play one move ahead then return the previous step. its hard to explain but not hard to program lol

i don't know how i can make the clicks. Which is better to have 9 divs and when to click them to send some ajax or buttons ?

its what ever you are more comfortable with coding ? with this there is no standard and with code there normally is not just one way... do the way you think you can or atleast prefer the sounds of.... or ...do both ? either way you are going to have to link to ajax for real time :L

Sounds quite a fun piece of homework haha.

 

How about doing a simple 3x3 table, with numerical id's. Use JQuery to add an event listener to look out for a click of a TD, grab the ID of the table and change the background image of that to one of the symbols. Once that's done, call an AI function which looks out for which images are in the grid, and where it could make a line using the numerical ID's?

 

If you need that logic doing in PHP, store the results in a DB once called to make a move and do the logic that way. Or, if you want something simple. just fire off the state of the full table every move so you can work out the AI's move without needed a DB.

[xScence]

Yep i understand this Jonny but im soo poor in ajax programming can i have some examples, thanks.

[Dick Montage]

Yup, someone asking people to do their homework.  If you are poor at ajax, you won't learn by people doing it for you.

<table>
	<tr>
		<td id='1-1'></td>
		<td id='1-2'></td>
		<td id='1-3'></td>
	</tr>
	<tr>
		<td id='2-1'></td>
		<td id='2-2'></td>
		<td id='2-3'></td>
	</tr>
	<tr>
		<td id='3-1'></td>
		<td id='3-2'></td>
		<td id='3-3'></td>
	</tr>
</table>

$('td').click(function(e) {
	makeMove(e.target.id);
});

function makeMove(square) {
	$.ajax("?square="+square function(data){
		//Set table background
		aiMove();
	});
}

function aiMove() {
	//AI Calculations
	//AJAX or 
}

That's very simple, but does that help? Just don't want to do your homework for you ;)

Seems kinda pointless involving PHP to be honest, makes much more sense for it all to be done in the browser (unless you want to add multi-player (node would be better here) or just save scores server side).

 

Only reason i can see to involve php would be if its some badly spec'ed out homework "/

If its homework, may just be to show how to hide game logic from the user so it isn't exploited as easily. Harder to force the AI to let you win if you don't have direct access to it the way you would with JavaScript. Just a guess though.

[xScence]

Thanks alot for the example jonny i will test it and work on it if it works. Thanks again

[xScence]

I got this:

 

<script>
$(document).ready(function(){


$('td').click(function(e) {
makeMove(e.target.id);
});


function makeMove(square){
$.ajax({
type: "POST",
url: "tictactoeAjax.php",
data: 'test=' + square,
success: function(data){
alert(data);
}
});
}
});


</script>


<table border="1" width="300" height="300" id="tictactoe" name="table">
<tr>
<td align="center" id='0'></td>
<td align="center" id='1'></td>
<td align="center" id='2'></td>
</tr>
<tr>
<td align="center" id='3'></td>
<td align="center" id='4'></td>
<td align="center" id='5'></td>
</tr>
<tr>
<td align="center" id='6'></td>
<td align="center" id='7'></td>
<td align="center" id='8'></td>
</tr>
</table>

But how can i set X and O backgrounds?, thanks.

Either with images, or just use jQuery's .html() to push X and O characters to the divs.

 

I really hope this isn't homework, at this point. :laugh:

[xScence]

Nope its not homework i just want to learn how to do it. I still don't understand how to do it... the logic and the ajax

[neohelp]

Absolutly makes no sense to do this with PHP.

[ILikeTobacco]

Absolutly makes no sense to do this with PHP.

You are 100% right. Being able to hide the source code from the player so they don't manipulate it is 100% useless. :rolleyes: Since you clearly have no real input for this discussion, I look forward to not seeing anymore posts from you so we can continue to see how xScence tackles this task.

I have this html:

$(document).ready(function(){


var turn = 0;
var tic = '';






$('td').click(function(e) {
turn = 1;
if(turn == 1){
tic = 'O';
}
makeMove(e.target.id);

function makeMove(square){


$.ajax({

data: { clicked: square, symbol: tic, bot: 0 }

$("#"+square).html('O');

}


function aiTurn(square){


turn = 2;


if(turn == 2){
tic = 'X';
}


$.ajax({
type: "POST",
url: "tictactoeAjax.php",
data: { clicked: square, symbol: tic, bot: 1 }
}).done(function(ret){
alert(ret);
$("#" + ret).html('X');
});


}
});
</script>
<body>


<table border="1" width="300" height="300" id="tictactoe" name="table">
<tr>
<td align="center" id='1'></td>
<td align="center" id='2'></td>
<td align="center" id='3'></td>
</tr>
<tr>
<td align="center" id='4'></td>
<td align="center" id='5'></td>
<td align="center" id='6'></td>
</tr>
<tr>
<td align="center" id='7'></td>
<td align="center" id='8'></td>
<td align="center" id='9'></td>
</tr>
</table>


</body>
</html>

The ajax:

<?php
require('conf.php');
session_start();
$clicked = $_POST['clicked'];
$symbol = $_POST['symbol'];
$bot = $_POST['bot'];


if($bot == 0){
//Human
$sql = mysql_query("UPDATE movies SET symbol = '".$symbol."' WHERE field='".$clicked."'") or die (mysql_error());
if($sql){
echo $symbol;
}
}elseif($bot == 1){
//AI
function ai_think(){
$sql = mysql_query("SELECT * FROM movies WHERE symbol = 'O'") or die (mysql_error());


while($rows = mysql_fetch_object($sql)){


//$rows->field returns 17

/*



*/

}


}
echo ai_think();
//$sql = mysql_query("UPDATE movies SET symbol = '".$symbol."' WHERE field='".ai_think()."'") or die (mysql_error());
}


?>

DB:

So now if player (me) clicked on 1 and 7 position the AI must place in position 4 so he will stop me to make 3 same symbols.
but if i use this code:

if($rows->field == 1 && $rows->field == 7){
//nothing happens
}
if($rows->field == 17){
//its stays in this if so if i make other operations they wont be checked because this returns allways true
}

I need some logic here: to check (most) strategy and stop them. Thanks alot.

while($rows = mysql_fetch_object($sql)){


//$rows->field returns 17


}
