Player TraceLine issue

[guljam]

I am using the Player :: GetNearByLocation function to spawn Special infected better than Director.

The problem is the Player :: CanTraceToLocation function when trying to find a place that Survivor can not see.
This is theoretically no problem.

Returning Utils.AreVectorsEqual (m_trace.pos, finish) on some maps is problematic.

For example, in map c2m5_concert.
GetNearByLocation finds a position in the tilted audience chair Navmash and when CanTraceToLocation decides.
It returns a false value with an error of Z axis (difference of 0.00035 for example) with a very slight difference.
It is also the same when the player is placed in a tilted navmash.

The conclusion is that the player can see its position, but the CanTraceToLocation function returns false.
So I modified it to "Utils.CalculateDistance (arr [i], m_trace.pos) <15) return true".
And with a little tolerance, I solved this problem.

So VSLib :: Utils :: SpawnZombieNearPlayer has a problem. I used this at first. It did not work well.
TraceMask should use MASK_OPAQUE. (Reason: transparent white barbed wire for example c2m2_fairgrounds)
I do not know why it traces the 128-height of the Z-axis. The general eye level of special infected is about 60.

Below is the function I created. Trace values ​​are returned more naturally in real situations.

---

function VSLib::Player::CanTraceLocationAround (where, tolerance = 15, traceMask = MASK_OPAQUE)
{
if(!IsEntityValid()) return;
if(!IsAlive()) return;

local eyepos = GetEyePosition();
local eyeang = GetEyeAngles();

local whereL = where + eyeang.Left().Scale(15);
local whereR = where + eyeang.Left().Scale(-15);

local arr =[where, whereL, whereR];

for(local i = 0; i < 2; i++)
{
	local m_trace = { start = eyepos, end = arr[i], ignore = _ent, mask = traceMask };
	TraceLine(m_trace);

	if(Utils.CalculateDistance(arr[i], m_trace.pos) < tolerance)
	{
		return true;
	}
}

return false;

}
