My question is how to make a different percentage chance to every of the case . Please reply

 

I assume that you are trying to make chances variate for each item, am I correct?

 

Yeah I think I want that

 

You mean..

PHP:

switch(mt_rand(1, 80)){
    case 1:
        switch(mt_rand(1, 3)){
            case 1:
                break;
        }
        break;
}


 

Try and make a function, maybe like this:

PHP:

/*
* @param int $value
* @param int $min
* @param int $max
*
* @return boolean
*/
public function isPercentage($value, $min, $max){
   $rand = mt_rand($min, $max);
   return ($rand > $min && $rand <= $value)
}

 

A percentage is taken out of 100. $max should be 100 and $min should be <= 100.

 

Can u write that in my code for example give case 1 13,5% chance please

 

Can u write that in my code , give for example case 1 13,5% chance please

 

Sorry but I'm new in plugin development and still don't know how the code 100% work

 

Did you mean 13.5% or 13% and 5%?

It isn't recommended to get started with the PocketMine API before you even know the principles of PHP.

 

25% example.

PHP:

$percentage = 25;
if(mt_rand(1, 100) <= $percentage){
    //...25%
}


 

Thanks bro u got like from me

 

But now tell me is this will work

PHP:

switch mt_rand(1,100){
 if (mt_rand <=25){
  case 1:
            /* 25 % to do case 1 */
  break;}
elseif (mt_rand <=30){
  case 2:
           /* 5% to do case 2 */
  break;}
elseif (mt_rand <=40){
  case 3:
           /* 10% to do case 3 */
break;}
else {
case 4:
           /* 60% to do case 4*/
break; }


Am i think good ? Btw written on phone
Or will it works ?

PHP:

switch mt_rand(1,100){
 if (mt_rand <=25){
  case 1:
            /* 25 % to do case 1 */
  break;}
elseif (mt_rand <=30){
  case 2:
           /* 5% to do case 2 */
  break;}
elseif (mt_rand <=65){ 
  case 3:
           /* 10% to do case 3 */
break;}
else {
case 4:
           /* 60% to do case 4*/
break; }
