Re: max. Random - Weirdosport - 17.05.2009

#define MAX 50
#define MIN 10

random(MAX-MIN) + MIN

For greater efficiency you might want to add:

#define RANDOMNUMBERTHING MAX-MIN so your computer doesn't constantly have to do MAX - MIN, but this is trivial..

I hvae it like this.

if(hour == 9 || hour == 10 || hour == 11)
{
new wea2 = random(MAX_WEA2-MIN_WEA2) + MIN_WEA2;
SetWeather(wea2);
}

Re: max. Random - Weirdosport - 17.05.2009

Put them in an array:

new WeatherIDs[3] = { 3, 12, 17 };

Then use something like:

WeatherIDs[random(sizeof(WeatherIDs))];

Outside everything, at top of script:

In the command/function

EDIT: I modified the code above a couple of times because I noticed a couple of mistakes, if it doesn't work check you have the latest version..

Thanks for good explaining. I understand and i think its works

Re: max. Random - Weirdosport - 17.05.2009

Unless you hadn't already guessed the line I gave you was quite a few functions rolled into one!

Explanation:

SetWeather(WeatherIDs[random(sizeof(WeatherIDs))]);

WeatherIDs is an array, so sizeof(WeatherIDs) returns how many spaces it has (3)

random(3) gives you a random number, either 0, 1, or 2.

WeatherIDs[1] is the second cell in the array, which in this case is 12.

The only downside is that you may get the same WeatherID twice in a row.

Re: max. Random - Justsmile - 17.05.2009

ok, woah i understand it perfectly. Thanks a lot Maybe you can say whats wroing with this:
It always says, tht more cops must be online.

if(Cops_On < 0)
{
GameTextForPlayer(playerid,"More Cops must be Online.",5000,3);
return 1;
}
new Cops[MAX_PLAYERS];
new Cops_On;
forward GetCops();
public GetCops()
{
Cops_On = 0;
for(new i=0;i<MAX_PLAYERS;i++)
{
if(IsPlayerConnected(i))
{
if(IsACop(i))
{
Cops[i] = 1;
Cops_On++;
}
else
{
Cops[i] = 0;
}
}
}
}
