Case statement with rand feature

[SirChick]

Is there a way to do something like this using php?

I dont know how to code this but this is the logic of my idea:

 

If exp =< 100

 

rand(1,5)

Include "You Loose".php

Include "You Loose".php

Include "You Win".php

Include "You Loose".php

Include "You Win".php

 

If exp > 100

rand(1,5)

Include "You Win".php

Include "You Win".php

Include "You Win".php

Include "You Win".php

Include "You Loose".php

okay what exactly are you trying to do

 

heres a go at it:

 

<?php

if ($exp <= 100)
{

}

?>

[thedarkwinter]

... sorry, pushed something

 

okay what exactly are you trying to do

 

heres a go at it:

 

<?php

$val = rand(1,5);
if ($exp <= 100)
{
  if ($val == 1) { incluude_once("youwin.php"; }
//  else....
}
else
{
  if ($val == 1) { incluude_once("youwin.php"; }
//...
}

?>

 

something along those lines?

[SirChick]

well ok ill explain.

 

If a player have 100 exp or less and they attempt to do a mission on my game as its called there needs to be a random amount of times they will succeed. For example:

 

Say they have less than 100 exp.

 

Now they try mission 1.

 

With less than 100 exp there is odds of like 2 in 5 chances of completion:

 

rand(1,5)

Include "You Loose".php

Include "You Loose".php

Include "You Win".php

Include "You Loose".php

Include "You Win".php

 

like that ^ the rand feature picture one of them 5 each time the rand is started.

 

 

But now say they have over 100 exp and do the same mission.... they now have 4 out of 5 chances of winning:

 

If exp > 100

rand(1,5)

Include "You Win".php

Include "You Win".php

Include "You Win".php

Include "You Win".php

Include "You Loose".php

 

 

Basically the rand will select one of the 5 possible choices. So its not predictable but there is always still a chance of a loss.

try

$chance = 20; //that % so 1 in 5
$gamble = rand(1, 100);

if($gamble =< $chance)
{
echo "win";
$gamble2= rand(1, 5);
switch($gamble2)
{
case 1:
include "win1.php";
break;
case 2:
include "win2.php";
break;
case 3:
include "win3.php";
break;
case 4:
include "win4.php";
break;
case 5:
include "win5.php";
break;
}

}else{
echo "loss";
}

It is "lose", not "loose" (i.e. not tight). And I would suggest not using php files with spaces in the names.

 

 

It can all be done in three lines:

<?php

$chance = ($exp<100)?2:4;

$inclFile = ($rand<=rand(1,5))?'You_Win.php':'You_Lose.php';

include($inclFile);

?>

[thedarkwinter]

okay so lets try this:

 

<?php

// whatever code is used to get the val of $exp

$val = rand(1,5); // generate random number to five

if ( ($exp < 100) and ($val > 3) ) { include ("win.php"); } // low experience, value is more than 3 = win
if ( ($exp < 100) and ($val <= 3) ) { include ("lose.php"); } // low experience, value is less/equal to 3 = lose
if ( ($exp >= 100) and ($val > 1) ) { include ("win.php"); } // high experience, value is more than 1 = win
if ( ($exp >= 100) and ($val = 1) ) { include ("lose.php"); } // high experience, value is 1 = lose

?>

 

hows that?

[SirChick]

woah there all so different! im confused on what each one is doing...

 

whats the ($val = 1) all about on that last one ?

 

 

Whats the ?2:4; all about on the end of the $chance line on the second code?

 

And i dont think the % is a wise idea on the 3rd because that means till be every 5th time which makes it not random

[Barand]

<?php

$win = ($exp <= 100) ?  rand(1,5) <= 2 : rand(1,5) <= 4;
include $win ? 'You Win.php' : 'You Lose.php';
?>

[Psycho]

<?php

//If $exp<100 sets $chance to 2, else it is set to 4
//Chance represents the chance in 5 that the user will win
$chance = ($exp<100)?2:4;

//Generates a random number (1-5) and if it is equal to or less than
//chance, sets the include file to the Win file, else sets it to the Lose file
$inclFile = (rand(1,5)<=$chance)?'You_Win.php':'You_Lose.php';

//Includes the file
include($inclFile);

?>

[thedarkwinter]

in mine i meant ($val == 1), sorry type

 

but the last post looks more efficient

[NArc0t1c]

Ooh..

<?php

$Number = rand(1,5);
If ($exp =< 100){
if ($Number < 4){
Include "You Loose.php";
} else {
Include "You Win.php"; }
else {
if ($Number < 2){
Include "You Loose.php";
} else {
Include "You Win.php"; } }
?>

 

Edit: Sorry, was afk, only saw the otehrs now.

[SirChick]

<?php

//If $exp<100 sets $chance to 2, else it is set to 4
//Chance represents the chance in 5 that the user will win
$chance = ($exp<100)?2:4;

//Generates a random number (1-5) and if it is equal to or less than
//chance, sets the include file to the Win file, else sets it to the Lose file
$inclFile = (rand(1,5)<=$chance)?'You_Win.php':'You_Lose.php';

//Includes the file
include($inclFile);

?>

 

Ok but say 2 out of 5 chances. That still means every 5 times u will win 2 correct? How would i alter the chances for different amounts like if it was out 20 attempts?

 

 

 

How come you all have different methods surely only one method should physically work :S

[Psycho]

Ok, I took Barands post as a challenge! here's a single line solution. I win!

 

<?php

$include 'You_' . (($exp <= 100) ?  ((rand(1,5) <= 2) ? 'Win':'Lose') : ((rand(1,5) <= 4) ? 'Win':'Lose' )) . '.php';

?>

[Barand]

<?php
include 'You_' . (($exp <= 100) ?  ((rand(1,5) <= 2) ? 'Win':'Lose') : ((rand(1,5) <= 4) ? 'Win':'Lose' )) . '.php';
?>

correct version - i win

[Psycho]

<?php

//If $exp<100 sets $chance to 2, else it is set to 4
//Chance represents the chance in 5 that the user will win
$chance = ($exp<100)?2:4;

//Generates a random number (1-5) and if it is equal to or less than
//chance, sets the include file to the Win file, else sets it to the Lose file
$inclFile = (rand(1,5)<=$chance)?'You_Win.php':'You_Lose.php';

//Includes the file
include($inclFile);

?>

Simply use variables in the code in place of the chance values and the random number max limit. I'd just create a function if it will be used many times with different values:

<?php

function winlose($expLimit, $lowchance, $highchance, $maxchance) {

 $chance = ($exp<$expLimit)?$lowchance:$highchance;

 $inclFile = (rand(1,$maxchance)<=$chance)?'You_Win.php':'You_Lose.php';

 return $inclFile;

}

$includeFile = winlose(100,2,4,5);
include($includeFile);

?>

 

And, there are many, many ways to accomplish the same thing in programming. The best solution will depend on a particular situation. For example, if you only needed this functionality for the values you originally specified I would not use a function. but, if you will be using different values, then a function is definitely the way to go.

[Psycho]

<?php
include 'You_' . (($exp <= 100) ?  ((rand(1,5) <= 2) ? 'Win':'Lose') : ((rand(1,5) <= 4) ? 'Win':'Lose' )) . '.php';
?>

correct version - i win

 

Doh! I was setting the result to a string so I could echo out the value for verification. Forgot to remove the damn dollar sign!

Could explain this bit:

 

$expLimit, $lowchance, $highchance, $maxchance

 

 

what is the "explimit" do i have to set that :S cos i dont understand that.. nor the high n low chance or max chance.. i cant work out its logic...

[Psycho]

Hmmm, if you were to look at the original commented code I would think it is self explanatory. Actually, the function needs to take one additional parameter: $exp

 

<?php

function winlose($expLimit, $lowchance, $highchance, $maxchance, $exp) {

  $chance = ($exp<$expLimit)?$lowchance:$highchance;

  $inclFile = (rand(1,$maxchance)<=$chance)?'You_Win.php':'You_Lose.php';

  return $inclFile;

}

//some code to computer $exp would be needed

$includeFile = winlose(100,2,4,5, $exp);
include($includeFile);

?>

 

The function will return back the file name to be included and takes the following paramters:

$expLimit: the "break point" for experience points which would determine which "chance" value would be used

$lowchance: the chance value to use if the exp points are below the $expLimit

$highchance: the chance value to use if the exp points are equal or greater than $expLimit

$maxchance: the maximum number of

$exp: the eperience points of the user

 

So the way to read this $includeFile = winlose(100,2,4,5, $exp); is as follows:

 

If the $exp value is less than 100, then there is a 2 in 5 chance that 'You_Win.php' will be returned, else 'You_Lose.php' is returned.

 

If the $exp value is greater than or equal to 100, then there is a 4 in 5 chance that 'You_Win.php' will be returned, else 'You_Lose.php' is returned.

 

Another way to think of it is a die. The $maxchance value detemines the number of side on the die (in this case a five sided die). The $expLimit along with the low and high chances determine what values on the die will produce a win vs. a loss.

 

For another example: let's suppose you want users with more than 500 points to have a 7 in 10 chance of a win and users with less than 500 points to have a 3 in 10 chance of a win. Then you would call the function like this:

 

$includeFile = winlose(500,3,7,10, $exp);
