Setting random amount (Min-Max) - weedxd - 02.10.2014

As you might see im using random number and max is 250. How may i set it to be random from 100-250 ?

PHP код:



public OnPlayerEnterCheckpoint(playerid)

{

    if(g_var[playerid] == 0 && IsPlayerInRangeOfPoint(playerid, 5,  2789.6619, -2517.8105, 16.1509))

    {

            DisablePlayerCheckpoint(playerid);

            new vehicleid = GetPlayerVehicleID(playerid);

            new string[128], amount;

            amount = random (250);

            format(string, sizeof(string), "*You've earned {FF6347}$%d{33CCFF} from dropping a car!", amount);

            SendClientMessage(playerid, COLOR_LIGHTBLUE, string);

            GiveDodMoney(playerid, amount);

            SetVehicleToRespawn(vehicleid);

            g_var[playerid] = 1;

            SetTimerEx("CountDown",1200*1000, false, "d", playerid);

        }

define:

pawn Код:

#define MIN_RAND 100
#define MAX_RAND 250

Try to change this:

pawn Код:

amount = random (250);

To:

pawn Код:

amount = random (MIN_RAND,MAX_RAND);

On this line i have the following warn:

Код HTML:

amount = random (MIN_RAND,MAX_RAND);

Код HTML:

warning 202: number of arguments does not match definition

Definition looks like this.

Код HTML:

//Dropcar
new g_var[MAX_PLAYERS];
#define MIN_RAND 100
#define MAX_RAND 250

@OP: use this function:

pawn Код:

minrandom(min, max)
    return min + random(max - min);

pawn Код:

stock GetRandomBetween(min, max)
{
    new num = random(max);
    if(num > min) return num;
    else if(num < num) return GetRandomBetween(min, max);
}

will work but may take time

edit: Vince got better thing :P

    new rand = random(max-min)+min;
    return rand;
}

and change

pawn Код:

amount = randomnumber(MIN_RAND,MAX_RAND);

that working for me

Re: Setting random amount (Min-Max) - Vince - 02.10.2014

Alright, let's suppose that you pass 100 and 250 to the function. What you would end up with (internally) is this:

pawn Код:

return 100 + random(250 - 100)

Which in turn gets simplified to

pawn Код:

return 100 + random(150)

Now, as you know the random function now returns a random value between 0 and 150. Let's suppose the random value is 0. The 100 from before gets added and 100 is returned. Let's suppose the random value is 149. Again, the 100 from before gets added and 249 is returned.

Usage is just the same as the regular random function.

pawn Код:

new randomNumber = minrandom(100, 250);

Issue fixed used my brain abit and found an example in the script.

Код HTML:

amount = 100+random(250);
