Talk:Ents.FindInCone

From GMod Wiki

Garry only added this 18 hours ago, so we don't know everything about it. If anybody knows what type the arguments are / has any examples or anything please add them. --~Toneo 22:01, 13 June 2008 (GMT-6)

This function does not appear to work at all. --Jephir 21:50, 1 July 2008 (GMT-6)

found out what it does

it finds stuff in a half-sphere, or maybe a spherical cap (see wikipedia)

i'll update the description of it. TomyLobo

Seems Broken

Through testing, I've found it doesn't *seem* to work, or at least not as I'd expect it to. So, I've made the following code as a surrogate:

 
function ents.FindInConeFix(p1,p2,Radius) -- apex, base point, base radius
	local tbl = {}
	local dist = p1:Distance(p2)
	local v1 = p2-p1
	v1:Normalize()
	for k,v in ipairs(ents.GetAll()) do
		local v2 = v:GetPos()-p1
		v2:Normalize()
		if v1:Dot(v2) >= (math.atan2(Radius,dist)*2) then
			table.insert(tbl,v)
		end
	end
	return tbl
end
