Percents - rumen98 - 12.05.2014

Hello I want to ask, for example is it possible to make code example I want to have a 20% chance to become IGInfo [playerid] [Owner] = 1; and in the other 80% to nothing happens.
Could this be done somehow?

pawn Код:
switch (random(10))
{
    case 0, 1:
    {
        // 20%
    }
}

PHP код:
case 0, 1: 
are percent options ? example
PHP код:
 case 0; 
is 10% ? and for 5% how to make ?

Re: Percents - Konstantinos - 12.05.2014

Using 10 as max in random function will let you to use it as 10, 20 .. 90, 100 percent. And yes, using case 0 is like using 10% for the above example.

However for using 5%, you'll need to change the max to 100 and check if it's the first 5 digits (0-4), then it's 5 percent.

switch (random(100))
{
    case 0 .. 4:
    {
        // 5%
    }
}

Hello again, I want to ask does this code generate 10 or 11 numbers in the sense of adding 0 as another number + those from 1 to 10 are 11 or so?

I ask because there wondering one thing and do not know whether it is so

with 27 numbers
PHP код:
    switch (random(27-RLTnfo[playerid][Chance]))
    {
        case 0,1: //7,40% - 28,57% by 20 level Chance
        {
        //code
        }
    } 
or

with 27 numbers plus a zero to the numbers from 1 to 27 = 28
PHP код:
    switch (random(27-RLTnfo[playerid][Chance]))
    {
        case 0,1: //7.14% - 25% by 20 level Chance
        {
        //code
        }
    } 
Which of these is the 2 correct?

Re: Percents - Konstantinos - 13.05.2014

Because the indexes in PAWN starts from 0 when you have size/max a number N, it's always: 0 to (N-1).

For example, using 10 is 0-9 (which is 10 in total).

I'm not sure if you can use floating-point numbers for that case.

Re: Percents - rumen98 - 13.05.2014

Ah, so the first one is true?
Here it
PHP код:
    switch (random(27-RLTnfo[playerid][Chance])) 
    { 
        case 0,1: //7,40% - 28,57% by 20 level Chance 
        { 
        //code 
        } 
    } 


Re: Percents - Konstantinos - 13.05.2014

No, it's not. The max value in random is unknown and with case 0/1 you won't get 7.40% - 28.57% percent.

Re: Percents - rumen98 - 13.05.2014

I think you do not understand exactly, then these percentages which I have written have a chance to drop these numbers by random (27) rates to fall 0 or 1 is 7.40% and at Level 20 Chance parameter, which removes 20 index and becomes random (7) the chance to fall 0 or 1 becomes 28.57%
