[SOLVED] need help with a while

[almightyegg]

When you battle a user in my game you get experience, and once you get a certain amount (level*level*150) you go up a level.

 

Sometimes a player can defea somebody who can give so much experience that they would gain several levels...How would I loop it so I don't have to write it out 100 times?

 

I need it to:

1. Level up

2. Upon Level up, re-add what exp you need until the next level

3. work out how much exp you have left after using some to level

 

thanks in advance

i don't really understand what you're saying, but this is the while format lol. also consider using a do-while loop or for loop

-------------------

while(condition) {

 

execute code

 

};

-------------

do{

 

execute code

 

} while(condition);

--------------

for (condition){

execute code

};

 

or something like that

Ummmm.... I'm not sure where you're getting this data from, but it would look something like this:

 

$user_level = $new_level = 1;
$user_exp = 0;
$exp_gain = 500;
$exp_tree = array(
     1 => 0,
     2 => 50,
     3 => 100,
     4 => 200,
     5 => 400,
     6 => 800,
);

while($exp_gain > $exp_tree[$user_level+1]) {
     $new_level++;
     $exp_gain -= $exp_tree[$new_level];
}

$level_exp = ($player_level + 1)_exp_value; // experience needed for next level

$exp_missing = $level_exp - $player_exp; // experience player still needs to advance level

while ( $total_exp_gained > $exp_missing ) // if experience needed is less than experience gained
{

$player_exp += $exp_missing; // increase player experience until next level
$player_level +=1; // increase player level
$total_exp_gained -= $exp_missing; // subtract experience just given to player from experience gained total

$level_exp = ($player_level + 1)_exp_value; // experience needed for next level

$exp_missing = $level_exp - $player_exp; // experience player still needs to advance level
}

 

I think i'd use something like this.

Ahhh... I came up with this:

 

function NewLevel($level, $exp, $gain) {
$next_exp = ($level)*($level)*150;
$sum = $gain + $exp;
while($sum >= $next_exp) {
	$level++;
	$sum -= $next_exp;
	$next_exp = $level*$level*150;
}
return array($level, $sum);
}

 

It of course doesn't need to be in function form, but it seemed easier to wrap my head around that way.  To not use it as a function, you could just set level exp and gain before it....

 

Anyway, this will take $level, $exp, and $gain and return the new level, the remaining exp, and how much exp is needed for the next level....

 

For example, if a player was level 1 with 40 exp and they gained 2000 exp, it would work like this:

 

player level 1

exp 40

gained 2000

 

sum = 2040

 

exp to level 2 would be level (1) squared times 150 1*1*150 = 150

sum > 150 so the players level would be incremented to 2, and their exp would be cut down 150 points (sum = sum - 150 = 1890)

 

exp to next level (level 3) would be current level squared times 150 (2*2*150 = 600)

1890 >= 600 so level is now 3 and sum is 1890 - 600 = 1290

 

exp to next level (level 4) would be current level squared times 150 (3*3*150) = 1350

 

1290 is not >= 1350, so the level would stay the same, and the player now has 1350 exp.

 

print_r(NewLevel(1, 40, 2000));

 

Will return:

 

Array

(

    [0] => 3

    [1] => 1290

    [2] => 60

)

Thanks everybody but I decided to go with Corbins way, it worked great thanks
