Am I only one who gets weird trace if you do more than two trace simultaneously?
It can't detect the displacements.

How can I force npc_metropolice to holster his stunstick?

Use a [img]http://wiki.garrysmod.com/favicon.ico[/img] [url=http://wiki.garrysmod.com/page/util/TraceLine]util.TraceLine[/url] going down from their feet and get the distance from the origin position and the hit position.

util.TraceLine downwards.

What others said + Also, [img]http://wiki.garrysmod.com/favicon.ico[/img] [url=http://wiki.garrysmod.com/page/Entity/IsOnGround]Entity:IsOnGround[/url] first to know that the distance is 0. I haven't tested but it might be possible for a traceline from the feet downwards to miss the floor surface.

Do a trace directly downward from the player's position

Is there a way to automatically clear the text inside a DTextEntry, once the user clicks it?

Try overriding [URL="https://github.com/garrynewman/garrysmod/blob/master/garrysmod/lua/vgui/dtextentry.lua#L319-L331"]OnGetFocus[/URL]

That worked like a dream. Thank you, MPan.

You'll probably wanna be careful with this. Every time you select the text entry again it will set the text to nothing.

You should probably check for a "IsUsed" variable and set it to true upon the first use.
[lua]function sometextentry:OnGetFocus()
if self.IsUsed then return end
self:SetText( "" )
self.IsUsed = true
end[/lua]

So I'm writing a script that changes map lighting on the fly with engine.LightStyle, and I've come across a problem - while props change their lighting somewhat consistently according to engine.LightStyle, the difference in lighting between sleeping objects to woken objects is way too visible, especially in dark environments. On r_radiosity 2, this is the difference between sleeping objects:
[T]https://cdn.discordapp.com/attachments/316871149491322881/318119436446072832/poster-17-05-27_23-12-31.png[/T]
And woken objects:
[T]https://cdn.discordapp.com/attachments/316871149491322881/318119447778951168/poster-17-05-27_23-12-29.png[/T]

Is there a (none r_radiosity related) way of reducing this difference or standardizing it so all props are lit as if they were asleep without actually waking them every couple of ticks?

so i was creating custom entity that randomizes 1 item out of 3 BUT it spawns 2 of them on middle of map and not in top of entity i didnt get any errors heres code

[lua]function ENT:Use( activator, caller )

local Rand = math.random(1, 3)
local SpawnHeight = 50
local Drop

if Rand == 1 then
Drop = ents.Create("item_ammo_ar2")
Drop:Spawn()
Drop:Activate()
elseif Rand == 2 then
Drop = ents.Create("item_ammo_pistol")
Drop:Spawn()
Drop:Activate()
elseif Rand == 3 then
Drop = ents.Create("item_ammo_smg1_large")
Drop:Spawn()
Drop:Activate()
end
end
[/lua]

did i forgot something?

[MysteryPancake]

You didn't set the position, and I think ENT:Use may be getting called twice for some reason

[editline]28th May 2017[/editline]

Also, I would rewrite the code to be a little simpler like so:

local drops = { "item_ammo_ar2", "item_ammo_pistol", "item_ammo_smg1_large" }

function ENT:Use( activator, caller )
    local drop = ents.Create( drops[ math.random( 1, 3 ) ] )
    drop:SetPos( self:GetPos() + Vector( 0, 0, 50 ) )
    drop:Spawn()
    drop:Activate()
end

Code looks fine to me, did you copy the parenthesis after the table closure?

Just thought I'd throw something in while I was doing some object debugging: adding the numbers to the cached vector element manually reduces the number of vectors created from three (GetPos, Vector(0,0,50), addition vector) to one. Ex.

local vPos = self:GetPos()
vPos[3] = vPos[3] + 50
self:SetPos(self:GetPos())

Slightly longer code, but saves rapid object creation/deletion.

Make sure you have set the use type to SIMPLE_USE.

Use self instead of entity. It's an entity function, but you need to provide it a variable

could anyone hook me up with simple lua code I could use to change a models texture using the entitys name (for lua_run entity in hammer)

[c👌de_g🎷]

[QUOTE=Rocketsurgery;52283924]could anyone hook me up with simple lua code I could use to change a models texture using the entitys name (for lua_run entity in hammer)[/QUOTE]

local t=ents.FindByName("name")for i=1,#t do t[i]:SetMaterial("some/material", true) end

[cpone]

If there's only one entity with the target name this should work:

ents.FindByName( "STICK THE NAME HERE" )[1]:SetMaterial( "MATERIAL IN HERE", true )

EDIT: Brain fart with lua tables.

Lua tables start from 1, not 0.

[SkitZz]

So i have this table structure, where i want to select stuff from.

local prize = {}
prize[1] = {
    item = "Blah1",
    amount = {"1000"}
}
prize[2] = {
    item = "Blah2",
    amount = {"2000"}
}
 
local pickPrize = prize[ math.random( #prize) ]
 
local generatedCode = generateCode(pickPrize.item, pickPrize.amount, "1")

But for some reason, the pickPrize.amount does not work? pickPrize.item works just fine. I am obviously selecting it wrong, but what is the correct way?

Looks fine to me; the only thing is that you're putting "amount" in a table in your prize element declaration, which means you'll have to do pickPrize_amount_variable[1] inside the function.
