Spawn IN Zone - RolePlayNews - 29.12.2014

Hi, how to make random spawn in the zone?

example.:

Код:

new Float:Points[12] =
    {2305.5264, 1783.7133, 2305.5264, 1882.6989, 2167.5994, 1882.6989, 2167.5994, 1859.0988, 2128.2075, 1783.7133, 2305.5264, 1783.7133};
    AdminHQArea = CreateDynamicPolygon(Points, 5.0, 15.0, sizeof(Points));

and spawn in zone (AdminHQArea) randomly.

Hello RolePlayNews,

It is a way more easier to find the coords inside rectangle, so if you don't want to overstrain, try to write a rectangle inside your polygon. Yes, with this you'll 'randomness' will be a way more inaccurate, but will always save up some priceless time c:

But, you can do it hardway. I won't write what has been already written, so I'll just give you a reference.

@GeeksforGeeks

There's C++ implementation on this problem, but I assume, that you will be able to rewrite it for your own usage, or just it will make you understand how to solve this on your own.

Good luck!
Greetings.

Ahh, thanks man!

You are best!

It's very easy to see if a point is in a lies within a polygon.

Код:

IsPointInDynamicArea(areaid, Float:x, Float:y, Float:z);

All you need to know is rectangle size from where points would be generated from to get some samples.

pawn Код:

// x1, y1, x2, y2 - Spawn generation
GenerateRandomSpawnInArea(areaid, Float:x1, Float:y1, Float:x2, Float:y2, &Float:randx, &Float:randy)
{
    new Float:tmp, Float:randx, Float:randy, xsize, ysize, Tries;

    if(x1 > x2)
    {
        tmp = x1;
        x1 = x2;
        x2 = tmp;
    }

    if(y1 > y2)
    {
        tmp = y1;
        y1 = y2;
        y2 = tmp;
    }

    xsize = floatround(x2-x1);
    randy = floatround(y2-y1);

    // Try up to 100 times
    while(Tries < 100)
    {
        randx = float(random(xsize));
        randy = float(random(ysize));

        if(IsPointInDynamicArea(areaid, x1+randx, y1+randy, 0.0)) return 1;
        Tries++;
    }
    
    return 0;
}
