Getting distance between players

[Jarva]

Hey, is there anyway to find all players within a certain range of one player rather than doing player.getAll()
And checking the vector:Distance() between them?

You could ents.FindInSphere, but then you would need to filter the result for only players. What you have described is the ideal way IMO.

You can use something like this.
[lua]
local Player = FindMetaTable("Player")
if !Player then return end

function Player:GetPlayersWithinRange(range)
local t = {}
for k,v in ipairs(player.GetAll()) do
if IsValid(v) and v != self and self:GetPos():Distance(v:GetPos()) <= range then
table.insert(t, v)
end
end
return t
end
[/lua]

use ents.FindInSphere and check if each found entity is a player or not.

Shouldn't checking the distance of all entities be slower than checking the distance of a list of players from a table [player.GetAll()]

And shouldn't this be v:GetPos():Distance(self:GetPos())

This is probably your best bet. If you don't wanna do it that way then...

[lua]
function PlayersNearMe(me, range)
local t = {}

local mypos = me:LocalToWorld(me:OBBCenter())
for _, pl in pairs(player.GetAll()) do
if me ~= pl and pl:NearestPoint(mypos):Distance(mypos) <= range then
table.insert(t, pl)
end
end

return t
end
[/lua]
