GetRandomVector returns over water sometimes

sometime the spawn is over the water not to far out from land what am i missing?

Code:

        Vector3 GetRandomVector()
        {
            float max = ConVar.Server.worldsize / 2;            float x = UnityEngine.Random.Range(max * (-1), max);
            float y = UnityEngine.Random.Range(200, 300);
            float z = UnityEngine.Random.Range(max * (-1), max);            object terrainHeight = GetTerrainHeight(new Vector3(x, 300, z));            if (terrainHeight is Vector3)
                return (Vector3) terrainHeight;
            else
                return new Vector3(x, y, z);
        }
        private static LayerMask GROUND_MASKS = LayerMask.GetMask("Terrain", "World", "Construction");
        object GetTerrainHeight(Vector3 location)
        {
         
            float distanceToWater = location.y - TerrainMeta.WaterMap.GetHeight(location);
            RaycastHit rayHit;
           if (Physics.Raycast(location, Vector3.down, out rayHit, GROUND_MASKS))
            {
                return rayHit.point;
            }            return false;
        }

 

another thing i noticed is if vector3 is close to a rad town you do not get ground level

 

You need to do something with the distanceToWater variable you created.

float waterDistance(Vector3 location)
{
return (TerrainMeta.HeightMap.GetHeight(location) - TerrainMeta.WaterMap.GetHeight(location) );
}

 

If you're just trying to determine if your point is is over water, you can use this:

Code:

// Vector3 position, returns true if terrain at coordinate (x, z) is under water
WaterLevel.Test(position);

A simple procedure I've used to get a random point on the terrain, excluding water, without raycasting (should fix your radtown issue):

Code:

Vector3 SelectTarget()
{
    // random select (x, z) target between (-1,-1) and (+1,+1)
    Vector3 target = new Vector3(UnityEngine.Random.Range(-1f,1f), 0f, UnityEngine.Random.Range(-1f,1f));
    // scale position to world size
    target *= (ConVar.Server.worldsize-1)/2;    // get terrain y position at target position
    float height = TerrainMeta.HeightMap.GetHeight(target);
    Vector3 pos = new Vector3(target.x, height, target.z);
    // check for water at position
    if (WaterLevel.Test(pos))
        return SelectTarget(); // over water, recurse
    else
        return pos;
}
