Posted: Mon Aug 02, 2010 8:53 am Post subject: PHP RPG

Project set by Holland (along with a few lines of starter code).
Quite proud of it myself, first thing I've done in php.

I tried to clean it up and comment it somewhat.

http://viral.stop.stylin-on.me/at/coding/php/rpgs/

Code:

<?php

session_start();
if(!isset($_SESSION['your_hp'])) #Starting a new game / lost session.
{
$_SESSION['potions'] = 3;
$_SESSION['your_hp'] = 100;
$_SESSION['his_hp'] = 100;
}

echo "<center>";

foreach ($_POST as $key => $value) { #Turning all $_POST into $_SESSION
$_SESSION[$key] = $value;
}

echo $_SESSION["usname"] . " " . "- Viral's RPG "; #Top info.
echo "------------------------------- ";
echo "<a href=./fightan.html>HARRRR</a> ";

$attackverb = array("swipe"=>0, "stab"=>1, "lunge"=>2, "hack"=>3, "slash"=>4, "rush"=>5,); #verb array

if($_POST["attack"]) #attacking
{
echo "You " . array_rand($attackverb,1) . " at your opponent! ";
$damage = rand(3, 14);
$opp_dam = rand (7, 26);
echo "You dealt " . $damage . " damage. ";

if($_SESSION['his_hp']<1) #so opponent doesn't attack after dead
 {
 session_destroy();
 echo "Victory! ";
 echo "<a href=./>Click here to play again</a>";
 }

echo "Your opponent dealt you " . $opp_dam . " damage. ";
$_SESSION['his_hp'] = $_SESSION['his_hp'] - $damage;
$_SESSION['your_hp'] = $_SESSION['your_hp'] - $opp_dam;
}

if($_POST["counter"])
{
$damage = rand(-34, 34);
if($damage=="0")
echo "No damage was inflicted. ";

elseif($damage<"0")
 {
 echo "Your counter failed, and you took " . $damage*-1 . " damage! "; #*-1 to remove negative, so output would make sense. eg. you took -5 damage. :|
 $_SESSION['your_hp'] = $_SESSION['your_hp'] + $damage;
 }

else
 {
 echo "Counter successful! You've inflicted " . $damage . " damage! ";
 $_SESSION['his_hp'] = $_SESSION['his_hp'] - $damage;
 }
}

$heal = rand(1, 28);

if($_POST["drink"]) #messsssy
{
if($_SESSION['your_hp']<100)
 {
 if($_SESSION['potions']==0) echo "No potions available. ";
 else
 {
 $_SESSION['your_hp'] = $_SESSION['your_hp'] + $heal;
 $_SESSION['potions']--;
 echo "Health replenished. ";

 if($_SESSION['your_hp']>99) #making sure you don't get buffed health
 {
 $_SESSION['your_hp'] = 100;
 }
 }
 }

 else
 {
 echo "Your health is already full! ";
 }
 echo "You have " . $potions . " potion(s) remaining. ";
 }

if($_SESSION['his_hp']<1) $_SESSION['his_hp'] = 0; #no negative health
if($_SESSION['your_hp']<1) $_SESSION['your_hp'] = 0;

echo " You now have " . $_SESSION['your_hp'] . " health left. ";
echo "Your opponent has " . $_SESSION['his_hp'] . " health left. ";

if($_SESSION['his_hp']<1) #victory
{
session_destroy();
echo "Victory! ";
echo "<a href=./>Click here to play again</a>";
}

elseif($_SESSION['your_hp']<1) #death
{
session_destroy();
echo "You have died. :( ";
echo "<a href=./>Click here to play again</a>";
}

echo "</center>";

?>

You lunge at your opponent!
You dealt 11 damage.
Your opponent dealt you 14 damage.

You now have 0 health left.
Your opponent has 0 health left.

Victory!

Click here to play again

Yeah I dunno, seems pretty difficult.

Fixed, Cryoma.

Code:

if($_POST["attack"]) #attacking
{
echo "You " . array_rand($attackverb,1) . " at your opponent! ";
$damage = rand(3, 14);
$opp_dam = rand (7, 26);
echo "You dealt " . $damage . " damage. ";
$_SESSION['his_hp'] = $_SESSION['his_hp'] - $damage;

if($_SESSION['his_hp']<1) #so opponent doesn't attack after dead
 {
 echo " You now have " . $_SESSION['your_hp'] . " health left. ";
 echo "Your opponent now has 0 health left. ";
 echo " Victory! ";
 echo "<a href=./>Click here to play again</a>";
 session_destroy();
 exit;
 }

 echo "Your opponent dealt you " . $opp_dam . " damage. ";
 $_SESSION['your_hp'] = $_SESSION['your_hp'] - $opp_dam;
}

Also fixed potions telling you that you have none remaining in two different ways.

Code:

if($_POST["drink"]) #messsssy
{
if($_SESSION['your_hp']<100)
 {
 if($_SESSION['potions']==0) echo "No potions available. ";
 else
 {
 $_SESSION['your_hp'] = $_SESSION['your_hp'] + $heal;
 $_SESSION['potions']--;
 echo "Health replenished. ";
 echo "You have " . $potions . " potion(s) remaining. ";

 if($_SESSION['your_hp']>99) #making sure you don't get buffed health
 {
 $_SESSION['your_hp'] = 100;
 }
 }
 }
else
 {
 echo "Your health is already full! ";
 }
}

Did you add a tie for dual-KO? And maybe the enemy can use potions too?

Would it be a good idea to make it where you can login and store items? _________________ Account reclaimed by former owner?

Possibly.
If I add a new enemy type, perhaps they'll be able to heal.
The reason I didn't for this one is that I made him somewhat OP, so you'd actually need potions.

Yes.
Though I assume that'd require mysql and such, and I've got less than no idea how to do that currently.

Just saw this and tested on your site:
Your script is open to XSS (Cross site scripting) because you're not sanitizing the user's name.
Change

Code:

echo $_SESSION["usname"] . " " . "- Viral's RPG "; #Top info.

Code:

echo htmlspecialchars($_SESSION["usname"]) . " " . "- Viral's RPG "; #Top info.

That'll make it so it echos out stuff like <script> and it's contents as text and not HTML
