Finding the minimum and maximum values of X and Y coordinates. - Scenario - 17.04.2013

Hello there!

I'm sure this is a simple task but I've only just woken up and can't seem to process a way to do it in my head. So... I figured I'd ask y'all!

I have four sets of XYZ coordinates stored in a variable like this:

varName[playerid][0][0], varName[playerid][0][1], varName[playerid][0][2]

Basically, the first [0] after [playerid] determines the set of data. Like I said, I've got 4 sets so the first [0] can actually increase to be [3] at the maximum. Then the second argument (the [0], [1], and [2]) refers to the X, Y, and Z coordinate, respectively.

I'm trying to create some dynamic areas (using Incognito's streamer plugin), but I need to determine the minimum X coordinate, the minimum Y coordinate, the maximum X coordinate, and the maximum Y coordinate. Obviously, a loop will be necessary. However, I just can't seem to figure out how in the world to do this.

Any thoughts?

Really easy actually, assume your first coordinate is your minimum then check every other coordinate to see if it is less do the opposite for the maximum.

pawn Код:

minxarray = 0;
minyarray = 0;
minzarray = 0;

maxxarray = 0;
maxyarray = 0;
maxzarray = 0;

for(new i = 1; i < sizeof(Array); i++)
{
      if(Array[i][0] < Array[minxarray][0]) minxarray = i;
      if(Array[i][1] < Array[minyarray][1]) minyarray = i;
      if(Array[i][2] < Array[minzarray][2]) minzarray = i;
}

for(new i = 1; i < sizeof(Array); i++)
{
      if(Array[i][0] > Array[maxxarry][0]) maxxarray = i;
      if(Array[i][1] > Array[maxyarry][1]) maxyarray = i;
      if(Array[i][2] > Array[maxzarry][2]) maxzarray = i;
}

Now you can add an area or whatever else you might want to do.

AddArea(Array[minxarray], Array[minyarray], Array[minzarray], Array[maxxarray], Array[maxyarray], Array[maxzarray]);

Easy

This is how I thought of this for Xmax:

pawn Код:

new Float:Xmax;

for(i=0; i< MAX_PLAYERS; i++)
{
    if (IsPlayerConnected(i))
    {
        for(new i2=0; i2<4; i2++)
        {
            Xmax=varName[i][0][0];
            if (i2>=1)
            {
                if (varName[i][i2][0]>varName[i][i2-1][0])
                {
                   Xmax=varName[i][i2][0];
                }
            }
        }
    }
}

Same goes for Ymax and Zmax.

EDIT: Apparently, I can't do math today, either.

It's working, thanks [uL]Pottus.
