you just run the script from your webserver / wamp server .. or just the same way you run any of ya pages..

[hallsofvallhalla]

yeah just run create_creatures instead of making it an include.

OR

in your attack.php comment out delete creature when hp = 0 or instead of delete, update it to maxhp and leave the exho thats says creature killed. Many way of doing this.

I get this when I go to localhost/tutorial/battle.php
does anyone know what i should change in the lines 13 and 33

this is the php:

Code: Select all

<?php
include 'connect.php';




$playerinfo="SELECT * from players where name='player1'";
$playerinfo2=mysql_query($playerinfo) or die("could not get player stats!");
$playerinfo3=mysql_fetch_array($playerinfo2);

$playerhp = $playerinfo3['hpoints'];
$playerattack = $playerinfo3['attack'];
$playerdefense = $playerinfo3['defense'];

if (isset($_GET['creature']))
{
   $creature=$_GET['creature'];
   $creatureinfo="SELECT * from creatures where name = '$creature'";
$creatureinfo2=mysql_query($creatureinfo) or die("could not get the creature you were fighting!");
$creatureinfo3=mysql_fetch_array($creatureinfo2);

}
else
{
  $creatureinfo="SELECT * from creatures order by rand() limit 1";
$creatureinfo2=mysql_query($creatureinfo) or die("could get a creature!");
$creatureinfo3=mysql_fetch_array($creatureinfo2);
}

$creature = $creatureinfo3['name'];
$creaturehp = $creatureinfo3['hpoints'];
$creatureattack = $creatureinfo3['attack'];
$creaturedefense = $creatureinfo3['defense'];

/////player info
echo "<u> " . $playerinfo3['name'] . "</u><br>";
echo "Hit points = " . $playerhp . "<br>";
echo "Attack = " . $playerattack . "<br>";
echo "Defense = " . $playerdefense . "<br><br><br>";

///////creature info
echo "<u> " . $creatureinfo3['name'] . "</u><br>";
echo "Hit points = " . $creaturehp . "<br>";
echo "Attack = " . $creatureattack . "<br>";
echo "Defense = " . $creaturedefense . "<br><br><br>";

echo "<a href='attack.php?creature=$creature'>Attack!";

?>

btw im a newbie.

You did setup the fields defense for the players table and creatures table, right? If not then that is the problem. If you do have it in make sure it is spelled exactly like it is in the script as PHP is case sensitive.

[hallsofvallhalla]

yep, sounds like a mysql field issue, check case!

Been playing around and I came up with and put in my attack.php

Code: Select all

mysql_query("UPDATE creatures SET hpoints = '10' WHERE name = 'orc'");
 
mysql_query("UPDATE creatures SET hpoints = '7' WHERE name = 'demon'");
         
mysql_query("UPDATE creatures SET hpoints = '5' WHERE name = 'wrench'");

This was based on earlier posts.

Am I ok with this? could I make it better?

------------------------------------------------------------------------------------------------------------------

I have also been playing with the level up. I had something kind of working so I registered another player and it didn't work correct. Now I don't remember the origianl code that I had for it to work.

Here is something close to what I had that was working for the one player in my DB.

Code: Select all

mysql_query("UPDATE players SET level = level + 1 WHERE exper > 100");

What am I missing?

I am a noob at this and try to figure out my changes. I am just having trouble with this one.

[Hutch]

Ok, I wasn't thinking to much when I was trying to do a level up yesterday.

This is what I have now. Any tips?

Code: Select all

if ($playerinfo3['exper'] > 100)

        $updateplayer = "update players SET level='1' where name='$player'";
        mysql_query($updateplayer ) or die("Could not update player");
        
        if ($playerinfo3['exper'] > 200)

        $updateplayer = "update players SET level='2' where name='$player'";
        mysql_query($updateplayer ) or die("Could not update player");
        
        if ($playerinfo3['exper'] > 300)

        $updateplayer = "update players SET level='3' where name='$player'";
        mysql_query($updateplayer ) or die("Could not update player");

        if ($playerinfo3['exper'] > 400)

        $updateplayer = "update players SET level='4' where name='$player'";
        mysql_query($updateplayer ) or die("Could not update player");

[hallsofvallhalla]

here is what I use and it works great

put this in a file called islevelup.php then in all your pages put include_once 'islevelup.php';

Code: Select all

 $expneeded = ($playerinfo3[level] * 100) * $playerinfo3[level];
  if ($playerinfo3[expe] >= $expneeded)
 {	echo "<br><br><a href='../levelup.php'><img src='../images/levelup.png' width='150' height='50' border='0'/></a>";}

this takes your level * 100 * level and makes that your exp goal. This way the higher your level is the more the exp gap grows.

Example

level 1
1 * 100 * 1 = 100, you need 100 exp
level 2
2 * 100 * 2 = 400, you need 400 exp

level 5
5 * 100 * 5 = 2500 and so on

1 line of code to figure the exp needed

then if current exp is greater than exp needed then place a button that will link you to a level up page, where you level up and bring the characters level up one, when its done the islevelup.php will figure the next exp amount needed.


its brilliant really


oh yeah by the way in your islevelup.php make sure you put a if statement saying if exp is > expneeded then level up, otherwise people will cheat and fast link the level up page

[Hutch]

Thank you

I knew there had to be an easier way then putting stuff for evry level.

[SpiritWebb]

Wow, I wasn't even ready for this part yet. This helps alot...thanks there Halls...lol!! :p
