hi, im trying to make an rpg, somewhat like kingdom of loathing (http://kingdomofloathing.com/), using php. so to kinda learn a little bit more about php i made this little mini rpg where you type something, and it says "you 'whatever you typed' your cow". theres a few things that say something else when you type them and one of them is "fight a dragon". this is where im having problems. when you type fight a dragon, i tried to make a battle with trogdor where you choose your attack and try to kill him, and it keeps going until somone dies. the whole thing was working before i tried to make a battle. i was wondering if somone could help me out with this. heres the code:

cowrpg.html:

<html>
<head>
</head>
<body bgcolor="black">
<br /><font color="white">
<form action="cowrpg.php" method="post">
You are a brave adventurer with a cow. What would you like to do with your cow?
<br />
Type action here: <input type="text" name="action" />
<input type="submit" />
</form></font>
</form>
</body>
</html>

cowrpg.php:

<html>
<head>
</head>
<body bgcolor="black"><br />
<font color="white">
<?php
$troghealth=10;
$yourhealth=10;
function battle()
{
echo "you wander around with your cow and find the mighty trogdor!<br />
choose your attack!<br />
trogdors health:" . $troghealth . "<br />your health:" . $yourhealth ."
<br />
<form action="cowbattle.php" method="post">
<input type="radio" name="attack" value="slice"/> slice
<br>
<input type="radio" name="attack" value="throw"/> throw
<input type="submit" />
</form>";
}
if ($_POST['action']=='kill')
echo "way to go, you killed your cow and lost the game stupid.";
elseif ($_POST['action']=='kick')
echo "you kick your cow,<br />poor cow.";
elseif ($_POST['action']=='eat')
echo "you eat your cow,<br />well, i guess you were hungry...";
elseif ($_POST['action']=='fight a dragon')
battle();
else
echo "you " . $_POST['action'] . " your cow.";
?>
<br /><br /><a href="cowrpg.html" target="1">play again?</a>
</font>
</body>
</html>

cowbattle.php:

<html>
<head>
</head>
<body bgcolor="black"><br />
<font color="white">
<?php
if ($_POST['attack']=='slice')
$troghealth-=2
$yourhealth-=5
echo "
you slice trogdor with your cow dealing 2 damage<br />
you were too close to trogdor and he burninates you dealing 5 damage<br />
choose your attack!<br />
trogdors health:" . $troghealth . "<br />your health:" . $yourhealth ."
<br />
<form action="cowbattle.php" method="post">
<input type="radio" name="attack" value="slice"/> slice
<br>
<input type="radio" name="attack" value="throw"/> throw
<input type="submit" />
</form>";
elseif ($_POST['attack']=='throw')
$troghealth-=2
echo "
you make sure to keep you distance and you throw your cow at trogdor dealing 2 damage<br />
your to far away for trogdor to burninate you<br />
choose your attack!<br />
trogdors health:" . $troghealth . "<br />your health:" . $yourhealth ."
<br />
<form action="cowbattle.php" method="post">
<input type="radio" name="attack" value="slice"/> slice
<br>
<input type="radio" name="attack" value="throw"/> throw
<input type="submit" />
</form>";
else if ($troghealth==0)
you win!<br /><br /><a href="cowrpg.html" target="1">play again?</a>
?>
else if ($yourhealth==0)
you lose!<br /><br /><a href="cowrpg.html" target="1">play again?</a>
?>
</font>
</body>
</html>

its very simple, the attacks do have the same result every time, basicly to win you just keep throwing the cow so you dont get close enough for trogdor to burninate you
im not sure if its a simple mistake, of if im way off
you can see a working version without the battle here (http://rtoot3.com/?p=92)

Basic scheme to handle such game in php:

[header html]

[get user state (before fighting, after fighting, etc)]

[handle user actions based on what state he is in]

[change state based on actions]

[display html for state]

[display any other html]

could you maybe show me what the code would be?
sorry, im really new to this

There is no fun if I do it :) So I won't do it :).

** goes to write simple example **

Ermm... ok, you owe me a beer :D

<?php
/* header */

session_start();
?>
<html>
<head>
</head>
<body style="background: black; color: white">
<br />
<form id="form_main" action="index.php" method="post">


<?php

$first_time = False;

if (isset($_SESSION["state"]))
{
$state = $_SESSION["state"];
} else {
$state = "start";
$first_time = True;
}

?>


<?php

if ($_POST["restart"] == "1")
{
$state = "start";
$first_time = True;
}

$state_selected = False;

if ($state == "start")
{
if ($_POST['action'] == "kill")
{
$state = "cow dead"; $state_selected = True;
}
elseif ($_POST['action'] == "eat")
{
$state = "cow eaten"; $state_selected = True;
}
}
else if ($state == "cow dead")
{

}

if ($state_selected == False && !$first_time)
{
echo "That action was not possible<br />";
}

$_SESSION["state"] = $state; // write it back to session variable

?>



<?php
if ($state == "start") {
?>

You are a brave adventurer with a cow. What would you like to do with your cow?
<br />
Type action here: <input type="text" name="action" />
<input type="submit" />

<?php
} elseif ($state == "cow dead") {
?>

Now it is dead. How are you gonna live now?
<br />
Type action here: <input type="text" name="action" />
<input type="submit" />

<?php
} elseif ($state == "cow eaten") {
?>

Why you had to do it? Game over!

<?php
}
?>

<br />
<br />
<input type="hidden" name="restart" value="0" />
<input type="button" value="Restart" onclick="restart.value = 1; document.getElementById('form_main').submit();" />

</form>
</body>
</html>

This, however, does not solve your problem. But you can create buttons for different actions like I did with button "restart". And now it is easy to expand game to infinity... almost.

thank you very much, but i still need to solve the battle system

Something like this:

<?php
} elseif ($state == "cow fight") {
?>

Fight is intense! You:
<br />
<input type="hidden" name="fightaction" value="" />
<input type="button" value="Bash" onclick="fightaction.value = 'bash'; document.getElementById('form_main').submit();" />
<input type="button" value="Smash" onclick="fightaction.value = 'smash'; document.getElementById('form_main').submit();" />
<input type="button" value="Slash" onclick="fightaction.value = 'slash'; document.getElementById('form_main').submit();" />

then handle it by checking $_POST['fightaction'] variable and change state as necessary.

You can also store numbers in $_SESSION["any_name_you_want"].
Just remember to clear those numbers when player restarts the game.

You might also want to take a look at ajax and xhtml as the php side

<font> tags are deprecated and should not be used.
ajax so that the users experience is much more enhanced as waiting for the page to re-load completely every time would remove from some of the user experience.

If I were to recommend a solution, which I am not sure I quite understand your question, I would say look into php sessions.

You could (in theory) add session variables to keep track of the health or position of your character. So, everytime they did an action, the dragon could advance so eventually he would be close enough to burn them.

Although, now that I think about it, you could implement it like it was suggested, use a series of buttons for different attacks, whenever a button is pushed, have the dragons position change.

Just a thought.

Session vars would not be a great option for this encase of a disconnect from the internet you would loose all statistics about your player. You would have to take a look at some sort of backend db for storage of the data.

This is a completly different way of thinking coming from an application development back ground. you need to use the DB as "a sort of memory management type thing", and just store some stuff in sessions to make the retrieval faster for things accessed often and only enough so you can retrive the correct(updated) info from the db.

Understood, and thank you. I was not sure what the OP was looking for. Just trying to offer different ways to observe it. I am by no means a programmer. lol!

oh well the thing is with my first code, when you typed something it just went blank, now ive got a better code, and only one file instead of three.
but now when you press one of the buttons it doesnt work, you can test the new version at http://rtoot3.com/test.php
here is the code

test.php

<?php

if ($_POST["restart"] == "1")
{
$state = "start";
$first_time = True;

$state = "cow eaten"; $state_selected = True;
}
elseif ($_POST['action'] == "cook")
{
$state = "cow cooked"; $state_selected = True;
}
elseif ($_POST['action'] == "kick")
{
$state = "cow kicked"; $state_selected = True;
}
elseif ($_POST['action'] == "punch")
{
$state = "cow punched"; $state_selected = True;
}
elseif ($_POST['action'] == "fight")
{
$state = "cow fight"; $state_selected = True;
}
elseif ($_POST['fightaction'] == "bash")

great... you killed your cow and lost the game, stupid.

<?php

you cook your cow into a well done steak,<br />
then you eat it.<br />
you lose.

<?php
} elseif ($state == "cow eaten") {
?>

you eat your cow<br />
wow, you really are stupid. you should have at least cooked it first!
<br />you lose.

I just post as I see things because other people might see them think it is a great (complete) solution and then sit for days trying to work out if they are disconnected they loose their info.

But sessions are defiantly the way to go with storing "who" the correct logged in user is maybe a username or something just make sure it is all stored some were in persistent memory (like a DB).

Think of a session as your RAM, and DB as your hard drive, you would not to be editing your thesis in your favorite editor it is all fine on the screen and your PC crashes with out having saved it to your hard drive?

Firstly the if this is the first experience with coding all the more reason to learn as much as you can :)

Start with this.http://www.php.net/manual/en/session.examples.php then http://ubuntuforums.org/showthread.php?p=5520180#post5520180

But you need to be telling php to start the session some where. (See examples and links)

Another minor issues is the $state is never set any where. (But I assume you haven't gotten to it yet)

That's not full code you see. Look at my example which he is using as base, there is session_start();

but now when you press one of the buttons it doesnt work

It works, you simply need the code which reacts to the changes you did.

if ($state == "start")
{
// this code reacts to commands when state == start
}
else if ($state == "cow fight")
{
// here you can put code which is active when state is actual fight
// like this
// because only in this state there exists such thing like fightaction
// now, don't create too many states, because you need code for every new state you make
// instead, you better create state "game over"
if ($_POST['fightaction'] == "bash")
{
$state = "game over"; $state_selected = True;
// and asign message to new variable which exists only in this state
$gameover_message = "blah blah blah";
}
elseif ($_POST['fightaction'] == "smash")
{
$state = "game over"; $state_selected = True;
$gameover_message = "blah blah blah2";
}
elseif ($_POST['fightaction'] == "slash")
{
$state = "game over"; $state_selected = True;
$gameover_message = "blah blah blah3";
}
}

<...>

...so you can print that message in game over state

<?php
} elseif ($state == "game over") {

echo $gameover_message;

}
?>

Remember, that's one of the million ways to do it... :) Don't take it for granted. You can create functions to simplify repetitive tasks, create cow object to store cow health, anything you want.

Yeah, session is temporary way to track the user, and as soon as you close browser window (let's say so), session ends.

I specifically haven't said anything about databases - because it complicates code even more, and no way I was going to write example with that - I just wanted to help getting started.

Mind you - databases are not hard, but it is one more language (SQL) and one more tool (MySQL).

Mind you - databases are not hard, but it is one more language (SQL) and one more tool (MySQL).

This is the HUGE problem with webdevelopment. I think ALL users should start with basic (static) html, add css, then work out some basic javascript, from then work on a server side scripting lang. then add database support.

This is more often then not never the case because of time constraints and not being able to make something productive with out the inclusion of all 6 completely separate langs that have completly different syntax makes this type of development harder.

I haven't posted complete working solution, I suggest you to experiment with what you have to get good understanding what is going on. Use "echo" to print variable values or additional info just for debugging, put more into $_SESSION variable to make game smarter, etc. Read on internet what exactly $_POST, $_GET, $_SESSION, $_SERVER is for, how they work.

you can still try it at rtoot3.com/test.php
but when you type fight, it works. but then when you press either of the three buttons it displays "this action is not possible" which is only suposed to happen when the variable $state_selected is false. but for all three of the actions in the code it makes $state_selected true.

but all these three actions are surrounded by

if ($state == "start")
{

}

and state is no longer "start", it's fight.

Firstly if you ever get a plank page it "mostly" means that the php code did not execute(ie bad syntax error)

best place to look

tail -f /var/log/apache2/error.log This is handy for when you are developing to have a terminal with that command running and you will be able to see all the errors that appear in your scripts.

OR

Change the way your server reports the errors (http://www.php.net/error-reporting) and put them on the screen. NB this is not recommended for production servers as it gives other users valuable information about your webserver/code layout. (But should be fine for home testing)

i dont run it from the terminal, i just upload it to my website every time i do something. how can i make it so i can run php files from my computor instead of my website so that i can see error messages? that would really help.

Take a look at my sig for installing and setting up PHP (it is very simple ) and then work on a local test environment and when you are ready to upload the files to your server go a head :)

Also I knew you did not run these via CLI but I thought the website was on your own local machine. So this might be a problem because you more then likely do not have access to ssh and the logfiles.

Did you look in the logs, did you try adding the error reporting stuff to your scripts?

Delever

November 2nd, 2008, 10:55 PM

Install apache server and php5 on your computer:

apache2 php5 libapache2-mod-php5

copy your "test.php" into "/var/www" (you will need write rights, for example, you can run nautilus with sudo (gksudo nautilus) to access that directory).

Access your page by going to http://localhost/test.php

Be default, you should see errors printed instead of blank page.

Imagine your code like this:

Every time you refresh your page (by clicking link or button), your script is executed. So, every time value 10 is assigned to $_SESSION['cowhealth'].

Basically, any variable is lost as soon as page is printed out for user. Except those variables you store in session.

To learn more about session, here are some useful links to tutorials:

http://php.about.com/od/advancedphp/ss/php_sessions.htm
http://www.tizag.com/phpT/phpsessions.php

nvm, found out session start has to go to the very top
but now the variable cowhealth still restarts to 10 every time you type something in again, and it doesnt show an error message or anything

With your cow health, you need to solve a problem (thats what programming is, problem solving): how to set cow health to 10 only the first time, and for any subsequent requests use value you set previously.

thank you so much! im so close to being done, but when cow health gets to 0, i want it to say

"dude, you gotta stop beating down your cows, you just killed it and lost the game, here, ill give you a new cow"

it does that correctly, but i also want it to reset cow health to 10, but for some reason it just keeps going down to negitives.

Game seems simple, but you actually need to check a lot of things.

I will give you an example how it can be done; read comments, then read them again. I suggest you to improve your version by taking bits and pieces you want from mine - that way you can learn more quickly.

In my version, I used some new things: like array to store player's data and array to store cow's data. Those arrays are $player and $opponent.

My version is not "best way to do it" - there is no "best" way, what should be important that it works.

And, in case I forgot - read comments. You will find many answers there.

best way to learn is to download some opensource projects ie phpbb3 and read the code there. Also reading programming guidelines can help with formating of your code and making code easier to maintain.

when i run it on my localhost it gives me these two errors

Warning: setcookie() expects parameter 2 to be string, array given in /home/placela/public_html/index.php on line 364

Warning: Cannot modify header information - headers already sent by (output started at /home/placela/public_html/index.php:10) in /home/placela/public_html/index.php on line 365

what happened there?
you can see the version before i tried using cookies here:
http://placelandia.com/
yup, i got a domain name for it.
also, look at the code for the stick figure, when you encounter a stick figure its supposed to show an image. but it doesn't.

lol, Im back with another problem, i tried to do it with cookies instead of sessions. heres the code

Take a look here (http://ubuntuforums.org/showthread.php?t=876312) for your session error look at my posts.

Please take a look at the php.net manual (http://www.php.net/setcookie) for the reason for your 2nd error. Your 2nd param is not a String but is an Array (many Strings). You need to only pass a single string varr into the 2nd param.

See it is an array.

$opponent = array(
'name' => $opponent_name,
'max_health' => 90,
'health' => 90,
'strength' => 30,
);

Not sure if you were meaning to pass $opponent_name instead of $opponent
