Marking players

[DeadShotKillz]

Is it possible to mark players similar to how it is in payday 2 in glua?

Yeah, halo.Add

I'm trying to make a swep that marks players when clicked on but it hasn't been going very well. I tried some code that Acecool recommended in a post about halos but it hasn't worked for me, here is the code of the PrimaryAttack function.

function SWEP:PrimaryAttack()

if(CLIENT) then
	return
end
local trace = util.TraceLine(tracedata)
local tr = trace.Entity
local pos = self.Owner:GetShootPos()
local ang = self.Owner:GetAimVector() 
local _color = tr:GetAccessLevelColor( );
local _sin = math.sinwave( 5, 1.5, true );
local tracedata = {}
tracedata.start = pos 
tracedata.endpos = pos + ang * 10000
tracedata.filter = self.Owner

if(trace.Hit) then
if(trace.Entity) then
	if(trace.Entity:IsValid()) then
		if(tr:IsPlayer()) then
	effects.halo.Add( { tr }, _color, 1 + _sin, 1 + _sin, 1 )
		
end
end
end
end
end

halo.Add needs to be called in [img]http://wiki.garrysmod.com/favicon.ico[/img] [url=http://wiki.garrysmod.com/page/halo/Add]halo.Add[/url]

Here is a very basic and simple example that should help you get started, it should 'tag' a player to be visible through walls like you wanted for 3 seconds. I haven't bothered to test or even re-read this small script so I can't guarantee that it works, but it should give you the general idea of what you have to do.

SWEP.TagDuration = 3

function SWEP:PrimaryAttack()
	local ent = self:GetOwner():GetEyeTrace().Entity
	if IsValid(ent) and ent:IsPlayer() then
		ent:SetNWInt("TaggedUntil", CurTime() + self.TagDuration)
	end
end

hook.Add("PreDrawHalos", "TaggedPlayerHalos", function()
	local plys = {}
	for _, v in pairs(player.GetAll()) do
		if v:GetNWInt("TaggedUntil", 0) > CurTime() then
			table.insert(plys, v)
		end
	end

	halo.Add(plys, Color(240, 20, 20), 2, 2, 1, true, false)
end)

Yeah, copied from wrong tab lol

Is halo.Add still problematic? i.e causes crashing/frame drops

[G😹nz😻]

this always caused several frame drops

[QUOTE=NiandraLades;46683602]Is halo.Add still problematic? i.e causes crashing/frame drops[/QUOTE]

It always will cause an FPS drop because it renders the entity several times over. Exact number of rerenders is controlled by passes argument.

I used to have issues with Halos on my old laptop... But I think it suddenly fixed.
