[Trigger] Question: Place unit out of specific Region

[DeadinAction]

Hey guys, hope you can help me on this

I try to do an event in Wurst-Script that periodically spawns some units on a random point of the playable map area. Now i want to check if the picked point would be in a 1000 radius of any players starting location and than pick a point out or on the border of that radius. My idea is to do some calculations with a dummy, but i have no clue how i can get a point out of the 1000 radius, or of the 1000 radius border.

I would be glad if someone can give me some tips to achieve this

Best regards

You can get random x/y, then check for the distance to an other point. (if you convert from GUI, you can see how they do it)

If it is in radius too close to one player's start point, you can simply re-roll the random x/y until it matches.

Thanks for your input

I have done some maths and created this, it works very well

It calcs the nearest point for the radius definition

function calcPointOutOfRegion(location spawn, location start, real radius) returns location
    real x1 = GetLocationX(start)
    real x2 = GetLocationX(spawn)
    real y1 = GetLocationY(start)
    real y2 = GetLocationY(spawn)

    real r = radius

    real m = (y2 - y1) / (x2 - x1)

    real b = y1 - (m * x1)

    real xnew1 = (m*y1 - m*b + SquareRoot(Pow(m, 2)*Pow(r, 2) - Pow(m, 2)*Pow(x1, 2) + 2*m*x1*y1 - 2*m*b*x1 + 2*b*y1 + Pow(r, 2) - Pow(b, 2) - Pow(y1, 2)) + x1) / (1 + Pow(m, 2))
    real xnew2 = (m*y1 - m*b - SquareRoot(Pow(m, 2)*Pow(r, 2) - Pow(m, 2)*Pow(x1, 2) + 2*m*x1*y1 - 2*m*b*x1 + 2*b*y1 + Pow(r, 2) - Pow(b, 2) - Pow(y1, 2)) + x1) / (1 + Pow(m, 2))

    real ynew1 = m * xnew1 + b
    real ynew2 = m * xnew2 + b

    real DistanceOfP1 = DistanceBetweenPoints(Location(xnew1, ynew1), spawn)
    real DistanceOfP2 = DistanceBetweenPoints(Location(xnew2, ynew2), spawn)

    return DistanceOfP1 <= DistanceOfP2 ? Location(xnew1, ynew1) : Location(xnew2, ynew2)
