[SOLVED] Random events

[xoligy]

Ok as some may of guessed im into online gaming now what i would like to do is make random events happen, of cause most the time nothing should happen bu every now and again i would like something to happen lol like the player gets a bonus of something, or his men die or he finds something lol

 

The way i was thinking was that i would need some sort or array with the list of things that "could" happen with maybe a random factor. I would also want it so only one bonus at a time could happen, can someone give me some advise?

 

Way i was thinking would be in a function using a random factor for the chance of something happening like 5-20% then the array of what could happen with another random factor hope that makes sense i know it dont to me lol

i use some thid like this,

$rand = rand(1,7);
	$r = rand(0,876)/1000;
	$r = number_format($r, 3);
	$stat = rand(1,;
		if($stat == 1) { $stat = strength; }
		elseif($stat == 2) {$stat = speed; }
		elseif($stat == 3) {$stat = magic; }
		elseif($stat == 4) {$stat = agility; }
		elseif($stat == 5) {$stat = speed; }
		elseif($stat == 6) {$stat = strength; }
		elseif($stat == 7) {$stat = agility; }
		elseif($stat == 9) {$stat = magic; }
		elseif($stat ==  {$stat = strength; }

	$color = rand(1,4);
		if($color == 1) { $color = red; }
		elseif($color == 2) { $color = yellow; }
		elseif($color == 3) { $color = blue; }
		elseif($color == 4) { $color = green; }


		if($rand == 1) { if($info['lab'] >= 1) { 

				echo " He injected you, You feel fine. Noting happend. <br /><br /><a href=town.php />Back to town</a> | <a href=?mod=lab&pill=yes />Take another Injection</a> "; $update_messages = mysql_query("UPDATE `members` SET lab=lab-1  WHERE `id`='{$info['id']}'") or die(mysql_error()); ;} else { echo " He has no injections left for you. <br /><br /><a href=\"town.php\" />Back to town</a> ";} 
		}
		elseif($rand == 2) { if($info['lab'] >= 1) { 

				echo " He injected you, You feel fine. You gain <strong><font color=\"green\">{$r}</font></strong> in <strong><font color=\"green\">{$stat}</font></strong> <br /><br /><a href=town.php />Back to town</a> | <a href=?mod=lab&pill=yes />Take another Injection</a> "; $update_messages = mysql_query("UPDATE `members` SET {$stat}={$stat}+{$r}, lab=lab-1  WHERE `id`='{$info['id']}'") or die(mysql_error()); ;} else { echo " He has no injections left for you. <br /><br /><a href=\"town.php\" />Back to town</a> ";}
		}
		elseif($rand == 3) { if($info['lab'] >= 1) { 

				echo " He injected you, You pass out due to extream pain as you wake you feel stronger some how, You gain <strong><font color=\"green\">{$r}</font></strong> in <strong><font color=\"green\">{$stat}</font></strong> <br /><br /><a href=town.php />Back to town</a> | <a href=?mod=lab&pill=yes />Take another Injection</a> "; $update_messages = mysql_query("UPDATE `members` SET {$stat}={$stat}+{$r}, lab=lab-1  WHERE `id`='{$info['id']}'") or die(mysql_error()); ;} else { echo " He has no injections left for you. <br /><br /><a href=\"town.php\" />Back to town</a> ";}
		}
		elseif($rand == 4) { if($info['lab'] >= 1) { 

				echo " He injected you, You pass out due to extream pain, You lost <strong><font color=\"red\">-{$r}</font></strong> in <strong><font color=\"red\">{$stat}</font></strong> <br /><br /><a href=town.php />Back to town</a> | <a href=?mod=lab&pill=yes />Take another Injection</a> "; $update_messages = mysql_query("UPDATE `members` SET {$stat}={$stat}-{$r}, lab=lab-1  WHERE `id`='{$info['id']}'") or die(mysql_error()); ;} else { echo " He has no injections left for you. <br /><br /><a href=\"town.php\" />Back to town</a> ";}
		}
		elseif($rand == 5) { if($info['lab'] >= 1) { 

				echo "You awake your body feels limp your eyes are all blured, You awake in the town square <meta http-equiv=\"refresh\" content=\"1;url=town.php\" />   "; $update_messages = mysql_query("UPDATE `members` SET lab=lab-1  WHERE `id`='{$info['id']}'") or die(mysql_error()); ;} else { echo " He has no injections left for you. <br /><br /><a href=\"town.php\" />Back to town</a> ";}
		}
		elseif($rand == 6) { if($info['lab'] >= 1) { 

				echo " You can feel the power flowing throught your veins you gain <strong><font color=\"green\">{$r}</font></strong> in <strong><font color=\"green\">{$stat}</font></strong>, As you leave the lab you notice a <font color={$color}>{$color} gem</font> in your pocket.   <br /><br /><a href=town.php />Back to town</a> | <a href=?mod=lab&pill=yes />Take another Injection</a> "; $update_messages = mysql_query("UPDATE `members` SET {$stat}={$stat}+{$r}, {$color}_gem={$color}_gem+1, lab=lab-1  WHERE `id`='{$info['id']}'") or die(mysql_error()); ;} else { echo " He has no injections left for you. <br /><br /><a href=\"town.php\" />Back to town</a> ";}
		}
		elseif($rand == 7) { if($info['lab'] >= 1) { 

				echo "You lose <strong><font color=\"red\">-{$r}</font></strong> in <strong><font color=\"red\">{$stat}</font></strong> due to the injection. <br /><br /><a href=town.php />Back to town</a> | <a href=?mod=lab&pill=yes />Take another Injection</a> "; $update_messages = mysql_query("UPDATE `members` SET {$stat}={$stat}-{$r}, lab=lab-1  WHERE `id`='{$info['id']}'") or die(mysql_error()); ;} else { echo " He has no injections left for you. <br /><br /><a href=\"town.php\" />Back to town</a> ";}
		}

 

there my be other ways to do it even easier ways but that works for me.

i was thinking it would be a load of if, elseif statments but wasnt sure lol tthanks for that may come in handy for a reference tho i know mine would have to be wrote alot different

[beansandsausages]

np could always made a db table with them then pull them from the database by there id?

[thebadbad]

This block:

 

<?php
		if($stat == 1) { $stat = strength; }
		elseif($stat == 2) {$stat = speed; }
		elseif($stat == 3) {$stat = magic; }
		elseif($stat == 4) {$stat = agility; }
		elseif($stat == 5) {$stat = speed; }
		elseif($stat == 6) {$stat = strength; }
		elseif($stat == 7) {$stat = agility; }
		elseif($stat == 9) {$stat = magic; }
		elseif($stat ==  {$stat = strength; }
?>

 

Can be rewritten into:

 

<?php
$powers = array('', 'strength', 'speed', 'magic', 'agility', 'speed', 'strength', 'agility', 'strength', 'magic');
if (in_array($stat, range(1,9))) {
$stat = $powers[$stat];
}
?>

 

Just to give you some ideas for optimizing. And instead of long if/elseif blocks, use switch(). Switch on true, if you want to check more than one variable. Example:

 

<?php
switch(true) {
case ($a == 1 && $b == 2):
	//do something
	break;
//etc.
}
?>

 

When switching on true, it may not take up less code, but it looks a lot cleaner to me.

For the way i have to do it, it be something like rand factor for something to actually happen so lets say there is a 50% chance of that then i would need a random choice of what "could" happen, i really need to try and write something and see how far off i am with this but at the moment my head isn't working :-/

[thebadbad]

Example script below. Each time it's loaded, there's a 50% chance that one of the specified events will happen. These events are equally likely to happen.

 

<?php
$chance = 50; //chance that an event will happen, in whole percent
$events = array(
'got strong',
'got speedy',
'got slow'
);
if (mt_rand(1, 100) <= $chance) {
echo $events[mt_rand(0, count($events) - 1)];
}
?>

thanks for that thebadbad seems to work a treat
