Zone & random positions - iJumbo - 28.11.2013

Hello
I'm trying to make a code that creates random positions within a zone, but I failed .. I have basically created a code that takes a random position in the line of perimeter i dont want that

How i can improve?

pawn Код:

stock CreateRandomPosInZone(Float:MinX, Float:MinY, Float:MaxX, Float:MaxY)
{
    new Float:Width = floatabs(MaxX - MinX);
    new Float:Height = floatabs(MaxY - MinY);
    new Float:Perimeter = (Width * 2) + (Height * 2);
    for(new i = 0; i != MAX_IT; i++) {
        new Float:C[2],Float:dist = modulus(random(9000), Perimeter);
        if(dist <= Width) {
            C[0] = modulus(random(9000), Width) + MinX;
            C[1] = MinY;
        } else if(dist <= Width + Height) {
            C[0] = MaxX;
            C[1] = modulus(random(9000), Height) + MinY;
        } else if(dist <= (Width * 2) + Height) {
            C[0] = modulus(random(9000), Width) + MinX;
            C[1] = MaxY;
        } else {
            C[0] = MinX;
            C[1] = modulus(random(9000), Height) + MinY;
        }
        printf("%f : %f",C[0],C[1]);
    }
}

Example:

pawn Код:

CreateRandomPosInZone(625.6991, -1895.0369, 631.7022, -1888.4351);

Returns:

I'm not really sure if this is what you want - it keeps the values between max and min but you don't know the height:

pawn Код:

forward Float: FRandomEx( Float: min, Float: max );

public OnFilterScriptInit( )
{
    new
        Float: rX = FRandomEx( 625.6991, 631.7022 ), // minX, maxX
        Float: rY = FRandomEx( -1895.0369, -1888.4351 ) // minY, maxY
    ;
    
    printf( "%f | %f", rX, rY );
    return 1;
}

stock Float: FRandomEx( Float: min, Float: max ) // The original RandomEx by ******, edited for the floats.
{
    return random( floatround( max ) - floatround( min ) ) + min;
}

I hope it works. By the way, change to:

pawn Код:

return random( floatround( max ) - floatround( min ) ) + floatround( min );

It seems to be better.
