How do I hide entities from player vision?

[dankiller94]

Say there's two players, each belong to Team A and Team B.

There is a prop_physics entity in front of both players. Player of Team A can see it but Player of Team B cannot see it. How do I do this?

You might aswell block the collision.
Define a team in the entity is the easiest way, then it is just checking and returning booleans!

In the Entity:Draw() (Which is clientside)

function ENT:Draw()
    if LocalPlayer():Team() == self.Team then
        self:DrawModel()
    end
end

And a hook somewhere (which is serverside)

hook.Add("ShoudCollide", "TeamEntityCollsion", function(player, entity)
    if isentity(player) and isentity(entity) and player:IsPlayer() then
        if player:Team() != entity.Team then
            return false
        end
    end
    
    return true
end)

You can do something with the PVS .. however have in mind that the entity that is blocked are useless on the client.

This has worked very well, thank you for directing me here.

Here is my code by the way, just wanna make sure if I'm doing things right.:
[lua]
hook.Add("PlayerSpawn", "GhostSpawn", function( ply )

if ply:Team() == TEAM_GHOST then
local grey = Color( 100, 100, 100, 0 )

ply:SetRenderMode(RENDERMODE_TRANSALPHA)
ply:SetColor(grey)

for _,v in pairs(ENTIG) do
print("Hello")
if IsValid(v) then
v:SetPreventTransmit(ply, true)
end
end

-- Not working, will get back to it eventually
timer.Simple( 1, function()
if (IsValid(ply) and ply:Alive() and pos) then
ply:SetMoveType( MOVETYPE_NOCLIP )
end
end)

timer.Simple( 4, function()
if (IsValid(ply) and ply:Alive() and pos) then
ply:SetMoveType( MOVETYPE_WALK )
end
end)

elseif ply:Team() ~= TEAM_GHOST then
ply:SetRenderMode(RENDERMODE_NORMAL)
ply:SetColor(Color( 255, 255, 255, 255) )
ply:SetCustomCollisionCheck(false)

for _,v in pairs(ENTIG) do
if IsValid(v) then
v:SetPreventTransmit(ply, false)
end
end
end

end)

hook.Add("PostCleanupMap", "GhostHideFromView", function()
for _,v in pairs(GHOST.AvoidEntities) do
for _,v2 in pairs(ents.FindByClass( v )) do
table.insert(ENTIG, v2)
end
end
end)
[/lua]

Should be fine. I haven't played much with the PVS as it couldn't block the players like I wanted to.
Play around with it and smooth the corners. Just remember that you have to re-enable PVS, if you want the entity to draw, render or make the client react to it.
