Question - How to make random based on percentage - buburuzu19 - 18.11.2014

Re: Question - How to make random based on percentage - Write - 18.11.2014

Pretty basic.

pawn Код:

new rand = random(3);
switch(rand)
{
    case 0:
    {
       SendClientMessage(playerid, -1, "You are a winner!");
    }
    case 1:
    {
        SendClientMessage(playerid, -1, "You are a loser!");
    }
    case 2:
    {
        SendClientMessage(playerid, -1, "You are a loser!");
    }

You can change the value of random times that you desire by changing "new rand = random(3);" to maybe 4 or 5 and then put new cases at the bottom.

I asked how to add percentage to random function.
I have a cmd named /getprize and i want to make the cases with percentage cuz i put some really really big prizes and for example the nrg can be won at a percentage of 1%.
That is what i am needing.

And that's exactly what I showed you up there, unless you want me to make a '/getprize' command for you entirely, in which I won't do.

You can however seek for such a request here; https://sampforum.blast.hk/showthread.php?tid=447813.

Then you just change his code a little bit?

pawn Код:

new rand = random(100);
switch(rand)
{
    case 1:
    {
       SendClientMessage(playerid, -1, "You are a winner!");
    }
    default:
    {
        SendClientMessage(playerid, -1, "You are a loser!");
    }
}

For example:
New randprize = random(3);
Switch(random)
{
Case: 0
{
SCM..."You won a NRG"
}
Case 1:
{
SCM..."You won 500$"
}
Case 2:
{
SCM..."You won 300$"
}
How to make case 0 to be hard to win.

//EDIT: oliverrud posted the correct solution already, didnt see it >.<
the correct way to do it.

1% chance to win, if it's 99 (100-1, cuz max of random is value-1) you'll win

pawn Код:

new rand = random(100);
switch(rand)
{
    case 0..98://simply means >= 0 and  <=98
    {
       SendClientMessage(playerid, -1, "You are a loser!");
    }
    default://the rest (99)
    {
        SendClientMessage(playerid, -1, "You are a winner!");
    }
}

How to make case 0 to be hard to win.

Simple solution off the top of my head would be something like this:

pawn Код:

New randprize = random(100);
Switch(random)
{
 Case: 0:
 { 
     SCM..."You won a NRG"
}
Case 1..15:
{
 SCM..."You won 500$"
}
Case 16..40:
{
  SCM..."You won 300$"
}
default:{
//yalost
}
