Portal 2 like "pointers"

[jimbodude]

Hey,

On my servers, I recently got requested to make Portal 2 like pointers for our gamemode. For those who don't know, these allow you to point anywhere in the world and "mark" it onscreen for your team mates (or partner, in Portal 2). I've done the basics (using crude NWVectors, but this is just a base and will be improved upon), but I was wondering if anyone had any further ideas to make it more Portal 2-esque. Particle effects perhaps, or entity highlighting?

[lua]
AddCSLuaFile("pointers.lua")

if SERVER then
local entities = {"prop", "func", "player", "sent", "heal" }
concommand.Add("pointer", function(ply, command, args)
if ply.Pointed and ply.Pointed + 10 > CurTime() then return end
ply.Pointed = CurTime()
ply:SetNWVector("pointer", ply:GetEyeTrace().HitPos)
ply:EmitSound("buttons/button15.wav", 500, 100)
if ply:GetEyeTrace().Entity then
local datent = ply:GetEyeTrace.Entity
for k,v in pairs(entities) do
if string.find(datent:GetClass(), v) then
hook.Add("Think", "DatPointer"..ply:EntIndex(), function()
ply:SetNWVector("pointer", datent:GetPos())
end)
end
end
timer.Simple(10, function()
if !ply:IsValid() then return end
ply:SetNWVector("pointer", Vector(0,0,0))
hook.Remove("Think", "DatPointer"..ply:EntIndex())
end)
end)
else
hook.Add("HUDPaint", "Pointers", function()
if !LocalPlayer or !LocalPlayer():IsValid() then return end
for k,v in pairs(player.GetAll()) do
local pos = Vector(0,0,0)
if v:Team() == LocalPlayer():Team() and !(v:Team() == 50 and LocalPlayer():Team() == 50) then
pos = v:GetNWVector("pointer") or Vector(0,0,0)
if pos != Vector(0,0,0) then
local toscreen = pos:ToScreen()
if !toscreen.visible then return end
local teamc = team.GetColor(v:Team()) or Color(255,255,255,255)
surface.DrawCircle(toscreen.x, toscreen.y, 20, team.GetColor(v:Team()) or Color(255,255,255,155))
surface.DrawCircle(toscreen.x, toscreen.y, 21, team.GetColor(v:Team()) or Color(255,255,255,155))
surface.DrawCircle(toscreen.x, toscreen.y, 22, team.GetColor(v:Team()) or Color(255,255,255,155))
local x = toscreen.x
local y = toscreen.y
local gap = 4
local length = gap + 10
surface.DrawLine( x - length, y, x - gap, y )
surface.DrawLine( x + length, y, x + gap, y )
surface.DrawLine( x, y - length, x, y - gap )
surface.DrawLine( x, y + length, x, y + gap )
end
end
end
end)
local down = false
hook.Add("Think", "Pointeryus", function()
if input.IsKeyDown(KEY_G) then
down = true
else
down = false
end
if down then
LocalPlayer():ConCommand("pointer")
end
end)
end
[/lua]

Instead of checking the key press on the Think hook, can't you just use GAMEMODE:KeyPress(key)?

Does nobody read the wiki anymore? [b][url=wiki.garrysmod.com/?title=Gamemode.KeyPress]Gamemode.KeyPress [img]http://wiki.garrysmod.com/favicon.ico[/img][/url][/b] is only for IN_ keys, not KEY_ keys.

How are these pointers...?

They work in the same way Portal 2 ones do, or near enough.
You point at a place in the world, and it marks that location on the HUD for both you and your team mates. This is a more crude way to do it, but it was requested by someone on my server, and I liked the idea.

Looks nice...
Could you make this to be used in Sandbox too?

It would be awesome.
