SWEP.DrawHUD() for Entity?

[BAZ]

I'm trying to draw a texture on screen, using an entity. But this does not seem as easy as it does with sweps ( SWEP:DrawHUD() ) How would I go about doing this?

Here's the texture code.

[lua] local entpos = self.Entity:GetPos():ToScreen()
local xm8 = Material("vgui/xm8_icon")
surface.SetMaterial(xm8)
surface.SetDrawColor(255,255,255,255)
surface.DrawTexturedRect( entpos.x, entpos.y, 20, 20 )
[/lua]

You would have to use a hook and loop through all the entities and draw what you need to, or loop through them all and call a custom DrawHUD function.

[lua]hook.Add("HUDPaint", "HUDPaintentityrtgsdk", function()
for _, ent in ipairs(ents.FindByClass("your_entity_class")) do
if ValidEntity(ent) and ent.DrawHUD then
ent:DrawHUD()
end
end
end)[/lua]

Using this code, you can use DrawHUD like with SWEPS.

Is that the only way?

I already have that running with a custom hud (Since it's part of a gamemode), but I thought finding my entity class every frame wouldn't be too efficient.

Well yes, because entities don't have HUDPaint functions.

Couldn't you just use something like this in the ENT:Init():

[lua]hook.Add("HUDPaint", "HUDPaintentity" .. self.Entity:EntIndex(), function() --special hook for each ent
self.Entity:DrawHUD() --draw the hud for this instance of the entity
end)[/lua]?

Or am I sadly mistaken?
(I dont use hooks much)

You are mistaken, the drawing code should be in a HUDPaint hook, so calling the entities DrawHUD in the HUDPaint hook is correct.

Which lua doc should I put this in shared, init, or cl_init?
I want to make it so that the lockpicking screen comes up but I will change the wording so that when using the entity, You will see a loading bar thats says like "Working..."

[Willox]

function ENT:Initialize()
    if CLIENT then
        hook.Add( "HUDPaint", self, self.DrawHUD )
    end
end

function ENT:DrawHUD()
    -- :)
end
