hello,
is there a place where i can find a good tutorial to create a mini map or even a grid map to make my character walking through it ?

thanks for your help,
eli

hrm... I once (several years ago on a computer that got fried by a lightning strike (no backup :( )) integrated a PHP site into a MUD.. it wasn't anywhere NEAR completion and only had a skeleton system up (hence why I didn't back it up), but I did have a minimap going. it was an smaug mud, and therefore based on vnums, making it easy enough to set up the map.. basically it set up a 7x7 square of squares (a table). the center square was the room your character was in. if there was an exit east the room to the right was added, etc, following exits until it left that 7x7 square then going back to the most recent room with an unexplored exit, and so on. it took a little while to parse but every room that existed in that 7x7 had a thick black border and any area where there wasnt a room had a light grey dashed border. if there was an exit "up" there was a blue "u" in the square and if there was an exit down there was a blue "d" in the square. I wanted to set it up so that if there was another player currently in that room (set something up with php sockets and the mud server to work together) then the background of the square would be green... however I did set it up so on mouseover you could see what monsters respawned in that room...

this is somewhat irrelevant, but I believe it is the type of system your wanting to integrate into your game, yes? how does your game work? I'm guessing you have an X and Y value in your charactor data, and a database containing room descriptions, exits, and x\y values (something like how a MUD works) or file names x-y.php dynamically created where you can create rooms easilly?


elaborate on how location data and areas are set up in your game and I may be able to help you.

hello,
you are absolutly right, since I post i manage to create a map based on x,y as each place and character have there own coordinate. I build the image with GDlibrairy, and make the character move with left right/right , up/down . preety easy at the end of the day . i forgoti have a few coffees too.

but your idea ofsocket in a MUD looks interesting though.

I have a quick question. Do I need to buy anythings like a domain or something on the internet to start my game?

[Auzzie]

it does help but some free php hosts let you have subdomains, to buy a domain though costs virtually nothing a year

[PunkRocker277]

I'm in the process of programming the battle system for my web based game and one problem I ran to was that I'm not sure how to make an attack only cause damage a percent of the time.

Would this work?:

<?php
$perecent = 60;
 
$rand = rand(1,100);

if ($rand <= $percent) {
	 echo "The attack worked!";
}
else {
	 echo "The attack failed";
}
?>

Can anyone help me?

[rules][/rules]

Google helps though and maybe you want to look up rand()

Sorry about that.
I updated my post. =D

[Auzzie]

That code is a very basic example of what you are after, yes

Thanks a lot.

Hey guys I'm having a problem with my battle system script.
When the opponent attacks it doesn't update my hp on the database and I can't find the problem.

Here is the script:

<?php
#run_battle.php
error_reporting(E_ALL);
#require connection file
require_once 'include/db-conn.php';

#require functions file
require_once 'include/functions.php';

First off a little tip, it might be better to post problems in the main php board, secondly after a brief glance i can see one glaring problem

mysql_query("UPDATE `Pokemon` SET `Pkmn_HP` = '$new_hp' WHERE `OwnerID` = '$_COOKIE[UserID]' AND `Slot` = '1'"); 

the cookie superglobal needs to be $_COOKIE['UserID'] and it is like that through all of your code. Hope it helps

[PunkRocker277]

So I have to change: $_COOKIE[UserID] to $_COOKIE['UserID']

This post has been edited by PunkRocker277: 01 February 2009 - 02:57 PM

[Auzzie]

Yes that is the only glaring thing that i can see

[PunkRocker277]

But isn't this: $_COOKIE[UserID] okay if it's in a string?

[Auzzie]

not really because you are trying to access a string within the $_COOKIE array
