[SOLVED] weird while() problem

uwannadonkey · August 13, 2007

if ( $user->agility > $enemy->agility)

{

$firstattack = '1';

}

else

{

$firstattack = '2';

}

while ($user->hp > 0 && $enemy->hp > 0)

{

if ($firstattack == 1)

{

$dmg = ($user->attack) - ($enemy->defense);

mysql_query("UPDATE `users` SET hp = hp-($dmg) WHERE ID = $_GET[iD]");

echo "$user->display_name"; echo' has done '; echo "$dmg"; echo ' damage against '; echo "$enemy->display_name";

}

if ($firstattack == 2)

{

$dmg = ($enemy->attack) - ($user->defense);

mysql_query("UPDATE `users` SET hp = hp-($dmg) WHERE ID = $user->ID");

echo "$enemy->display_name"; echo' has done '; echo "$dmg"; echo ' damage against '; echo "$user->display_name";

}

if ($firstattack != 1)

{

$dmg = ($user->attack) - ($enemy->defense);

mysql_query("UPDATE `users` SET hp = hp-($dmg) WHERE ID = $_GET[iD]");

echo "$user->display_name"; echo' has done '; echo "$dmg"; echo ' damage against '; echo "$enemy->display_name";

}

if ($firstattack != 2)

{

$dmg = ($enemy->attack) - ($user->defense);

mysql_query("UPDATE `users` SET hp = hp-($dmg) WHERE ID = $user->ID");

echo "$enemy->display_name"; echo' has done '; echo "$dmg"; echo ' damage against '; echo "$user->display_name";

}

thats my code, its my first time using the while() function, and im not very clear with it.

no errors show up, and nothing happens, i mean, the page stays blank. can anyone help me?

is it the &&?

MadTechie · August 13, 2007

never ending loop,

you need to update the values for

$user->hp

$enemy->hp

uwannadonkey · August 13, 2007

how would i do that? i thought it did that by itself.

thx for the reply by the way

uwannadonkey · August 13, 2007

if it was a never ending loop, wouldnt it never load the page? the page loads, but nothing happens :/

MadTechie · August 13, 2007

OK add this

if ( $user->agility > $enemy->agility)
{
$firstattack = '1';
}
else
{
$firstattack = '2';
}

while ($user->hp > 0 && $enemy->hp > 0)
{
die("IN the WHILE LOOP ");//ADD THIS
echo "attack<br>"; //add
flush(); //add
if ($firstattack == 1)
{
$dmg = ($user->attack) - ($enemy->defense);
mysql_query("UPDATE `users` SET hp = hp-($dmg) WHERE ID = $_GET[iD]");
echo "$user->display_name"; echo' has done '; echo "$dmg"; echo ' damage against '; echo "$enemy->display_name";
}
if ($firstattack == 2)
{
$dmg = ($enemy->attack) - ($user->defense);
mysql_query("UPDATE `users` SET hp = hp-($dmg) WHERE ID = $user->ID");
echo "$enemy->display_name"; echo' has done '; echo "$dmg"; echo ' damage against '; echo "$user->display_name";
}
if ($firstattack != 1)
{
$dmg = ($user->attack) - ($enemy->defense);
mysql_query("UPDATE `users` SET hp = hp-($dmg) WHERE ID = $_GET[iD]");
echo "$user->display_name"; echo' has done '; echo "$dmg"; echo ' damage against '; echo "$enemy->display_name";
}
if ($firstattack != 2)
{
$dmg = ($enemy->attack) - ($user->defense);
mysql_query("UPDATE `users` SET hp = hp-($dmg) WHERE ID = $user->ID");
echo "$enemy->display_name"; echo' has done '; echo "$dmg"; echo ' damage against '; echo "$user->display_name";
}
}

if you dont get a message "IN the WHILE LOOP " then your values are lower than 0,

comment that line out and see what happens

uwannadonkey · August 13, 2007

i added it, and nothing was written, well nothing that wasnt there before.

PS what do u write to put the php in that box, just like you just did.

MadTechie · August 13, 2007

use the # button (on the toolbar) AKA

add to the start
[code]
echo "User  HP:".$user->hp;
echo "<br>Enemy HP:".$enemy->hp;

your see the theirs no value

are you including the class ?

uwannadonkey · August 13, 2007

you are right, there is no value for enemy hp, but i set it...

<?php
include('inc/header.php');





if (isset($_GET[iD]));
{
$result2 = @mysql_query("SELECT * FROM users WHERE ID = '$_GET[iD]'"); 
$temp3 = @mysql_fetch_object($result2);
$enemy = $temp3; 
echo "$user->display_name"; echo ' VS. ';echo "$enemy->display_name<br>";
}
if ($enemy->ID == $user->ID)
{
echo' You cant attack yourself!';
}
elseif ($user->hp <= 0)
{echo ' You are in NO condition to do battle';
}
elseif ($enemy->hp = 0)
{
echo ' Your Enemy Is Already Dead!';
}
elseif ($user->energy <= 4)
{
echo ' Not enough energy!';
}
elseif ($user->attack < $enemy->defense)
{
echo ' You look at your opponent, and wet your pants at his/her strength.  You lose the battle.<br><br><br><br><br><br><br><br><br>';
mysql_query("UPDATE `users` SET hp = 0 WHERE ID = '$user->ID'");
}
elseif ($user->defense > $enemy->attack)
{
echo' Your opponent takes one look at you, and dies in fear<br><br><br><br><br><br><br><br><br>';
mysql_query("UPDATE `users` SET hp = 0 WHERE ID = '$_GET[iD]'");
}
else
{
echo' Welcome to the Battle Arena.';
if ( $user->agility > $enemy->agility)
{
$firstattack = '1';
}
else
{
$firstattack = '2';
}
echo "User  HP:".$user->hp;
echo "<br>Enemy HP:".$enemy->hp;
while ($user->hp > 0 && $enemy->hp > 0)
{

echo "attack<br>"; //add
flush(); //add
if ($firstattack == 1)
{
$dmg = ($user->attack) - ($enemy->defense);
mysql_query("UPDATE `users` SET hp = hp-($dmg) WHERE ID = $_GET[iD]");
echo "$user->display_name"; echo' has done '; echo "$dmg"; echo ' damage against '; echo "$enemy->display_name";
}
if ($firstattack == 2)
{
$dmg = ($enemy->attack) - ($user->defense);
mysql_query("UPDATE `users` SET hp = hp-($dmg) WHERE ID = $user->ID");
echo "$enemy->display_name"; echo' has done '; echo "$dmg"; echo ' damage against '; echo "$user->display_name";
}
if ($firstattack != 1)
{
$dmg = ($user->attack) - ($enemy->defense);
mysql_query("UPDATE `users` SET hp = hp-($dmg) WHERE ID = $_GET[iD]");
echo "$user->display_name"; echo' has done '; echo "$dmg"; echo ' damage against '; echo "$enemy->display_name";
}
if ($firstattack != 2)
{
$dmg = ($enemy->attack) - ($user->defense);
mysql_query("UPDATE `users` SET hp = hp-($dmg) WHERE ID = $user->ID");
echo "$enemy->display_name"; echo' has done '; echo "$dmg"; echo ' damage against '; echo "$user->display_name";
}
}
}
include('inc/footer.php');
?>

Thats the full code on the page

on the page, it show:

GOD VS. CatNCobra

Welcome to the Battle Arena.User HP:190

Enemy HP:0

which means that enemy->display_name is working, because the enemies name is there, right?

MadTechie · August 13, 2007

change the

$enemy->ID

to

$enemy['ID']

$enemy->hp

to

$enemy['hp']

etc etc etc etc

try a few and check it works then continue

EDIT AHHH wait a sec..

echo "$user->display_name"; echo ' VS. ';echo "$enemy->display_name<br>";

worked !

*thinking*

try print_r($enemy), and post the result from that

uwannadonkey · August 13, 2007

ok, ill change em all and get back to you

GOD VS. GOD

Welcome to the Battle Arena.User HP:190

Enemy HP:

MadTechie · August 13, 2007

can you

echo "enemy";

print_r($enemy);

echo "user";

print_r($user);

and post the result from that

i think their around the wrong way!

off the bat, it says :

Parse error: syntax error, unexpected T_IF in /home/donkey9/public_html/attack.php on line 8

wait, is that the semi colon u put after the if statement?

EDIT

*not the semi colon

MadTechie · August 13, 2007

lol opps

updated it

uwannadonkey · August 13, 2007

CatNCobra VS. CatNCobra

You cant attack yourself!This page took 0.000095 seconds to load.

why is he attacking himself now?

$enemysql = @mysql_query("SELECT * FROM users WHERE ID = '$uID'");

$enemy = @mysql_fetch_object($enemysql);

$usersql = @mysql_query("SELECT * FROM users WHERE ID = '$uID'");

$user = @mysql_fetch_object($usersql);

thats the problem

*edit* user is set in the header include on the top of the code

why set it again, and the same value as enemy?

MadTechie · August 13, 2007

i made a few updates, try now

uwannadonkey · August 13, 2007

more problems:

u didnt set eID at all

and this is what shows up:

CatNCobra VS.

Your opponent takes one look at you, and dies in fear

*Edit*

like i said previously, USER is set in the header file, so should i remove that part of codE?

noticed ur error, the get[id] gets the enemie's ID from the url

and the user is always included in the file header

i modified ur code into this:

$uID = $user->ID;
$eID = (int)$_GET['ID'];
if ($uID > 0) //changed
{
$enemysql = @mysql_query("SELECT * FROM users WHERE ID = '$eID'"); 
$enemy = @mysql_fetch_object($enemysql);
$usersql = @mysql_query("SELECT * FROM users WHERE ID = '$uID'"); 
$user = @mysql_fetch_object($usersql);

echo "$user->display_name"; echo ' VS. ';echo "$enemy->display_name<br>";
}else{
die("error");

and this shows up

GOD VS. CatNCobra

Welcome to the Battle Arena.User HP:190

Enemy HP:0

MadTechie · August 13, 2007

remember i can't test this,.. ok

i have reviewd everything (i think)

Wait noticed a ton

some fo the logic is a little weird!

would you mind if i update a few thing ?

uwannadonkey · August 13, 2007

i wrote stuff on my previous post, after changing ur code a bit, i think its starting to work, up until the while() code

lol, sure, anything that can help!

(PS thanks for helping me so much already, and thanks for sticking with this.)

i ono why the enemy HP is showing as 0, ID 9 in mysql is 100 hp

MadTechie · August 13, 2007

is the $_GET['ID'] the ID from the attacker ?

uwannadonkey · August 13, 2007

$get[id] is the ID of the enemy

ie:

the user attacks the enemy, and the enemies ID is in the url

does that help ?

MadTechie · August 13, 2007

OK

<?php
include('inc/header.php');
