Right thats what I've managed so far, the issues I'm having is removing an effect I don't know how to reference it.

You want something like that ? If you close the mainframe it automaticly close the child ?

Use the render lib render.DrawBeam and The HUDPaint hook.

[lope]

I want it so that when you press the button (Terrorist) it closes all the Derma's. So like you click the terrorist button and everything closes and you can play.

[lua]function DrawBeamAim() local eyestart = LocalPlayer():GetEyeTrace().StartPos
local eyeend = LocalPlayer():GetEyeTrace().HitPos

local laser = Material("effects/laser1")
render.SetMaterial(laser)
render.DrawBeam( eyestart, eyeend, 10, 1, 1, Color( 255, 255, 255, 255 ) )
Msg ("Runningdrawbeam")
end

hook.Add("HUDPaint", "DrawBeamAim", DrawBeamAim);[/lua]

Why wouldn't this be working then? It compiles fine and if I add prints to debug it, it makes it through the whole block of code.

another error :/

YES! Thank you wiki, I got my problem fixed.

Got it to work by using the PostPlayerDraw hook. Not sure if that's a good thing but as far as I can research it seems to be one of the only viable ways of drawing an aiming beam in 3d space that other players can see.

Hello,

In my SWEP, there originally was a delay in how you attacked the player, but there's problems:

1) I split the attack up into two parts, which causes when I look at an NPC/player they die immediately (sometimes)
2) I want to fire a bullet without using self:PrimaryAttack()

Need some code? Here's what it is right now:

[lua]if not attacking then
local tr = self.Owner:GetEyeTrace();
if CurTime() >= killTimer+2 then --if current time is greater than itself, plus two, or some other value..

if tr.HitNonWorld && (tr.Entity:IsPlayer() || tr.Entity:IsNPC()) and IsValid(tr.Entity) then --Are we looking at a player or NPC? If yes..
self:Caught(tr.Entity) --ah shit, they got caught, good job!
end

end

if CurTime() >= killTimer+8 and tr.HitNonWorld && (tr.Entity:IsPlayer() || tr.Entity:IsNPC()) and IsValid(tr.Entity) then --Are we looking at a player or NPC? If yes..
self:PrimaryAttack() --ATTACK!
killTimer = CurTime() + delay --delay the next shot
end
end[/lua]

well you made two if statements with nearly the same conditions. Since the conditions are both being met, both if statements are ran.

Hey, I'm unable to get the AddCSLuaFile to work on my server. It worked 100% fine on my dev server but when I upload it to the main server, I get these errors.

Is there a length limit to strings in GMod Lua that isn't in regular Lua? I ran and tested the output of a script in Lua, and am in the process of running it in the gamemode code.. but printing the output of the string gets cut off somewhere around 1000 characters. Or is this just a limitation of the print statement?

I've spent a lot of time debugging this and can't seem to figure it out. Even if I manually append text to the end of the string variable, it's not printing it. Madness!

The code basically takes a table structure that represents the database, and converts it into an sql string either for mysql or sqlite. It is for the initial creation of the database structure - a first time install.

Am I just confused here or am I really supposed to take this and break it up into a bunch of mini statements? I thought perhaps that I would send each query separately, but I would still have to write code to handle the case that any query comes to a string length of more than 1024 characters? Is that for real?

My trace isn't hitting the world it's drawing to its maximum what could going wrong here?

view.angles = Angle(45, 180, 0)
view.fov = fov

local pointertrace = {}
pointertrace.startpos = view.origin
pointertrace.endpos = pointertrace.startpos + LPCameraScreenToVector( gui.MouseX(), gui.MouseY(), ScrW(), ScrH(), angles, math.rad(fov) ) * 5000
pointertrace.filter = ply

local tr = util.TraceLine(pointertrace)
if tr.Hit then
print(tr.HitPos)
print("\n")
end

return view
end

iScreenY is the y position of your cursor on the screen, in pixels.

[QUOTE=Sean C;39141822]By adding a hook that already exists would you mean like having hook.Add("CalcView" ...1view) in one place in the code and hook.Add("CalcView"...view2) somewhere else? Would that be okay as long as they don't modify the same information or should it just all be contained into one function?

Wouldn't removing the hook as in your snippet just remove the new functionality for the hook from the gamemode altogether? Or for your example would you have two different CalcView calls like I just described but run that removal code inbetween them so the first CalcView hook is removed before the second is run?[/QUOTE]

I just combine all my code into one hook, no reason to create more than one. It would be okay to do, but it would be inefficient.

And no, I put that at the top of my scripts, so that the new hook that I add doesn't collide with the old one. Hooks are ran in the order they're added, so the old one would run first (that is, if hooks stack, but I don't think it works like that).

If you're wanting to just remove one hook and then make a new one, just do hook.Remove with just the name. That loop I posted removes all hook with a certain prefix.

At first, I was like, why in the hell are you using an effect?
Also, I was actually doing this myself. Here's my render code:

hook.Add("PostDrawOpaqueRenderables", "sc_cl_tpc_Laser", function()
	...
	render.SetMaterial(HUDLaserMaterial)
	render.DrawBeam(MuzzlePos, FinalPos, 0.75, 0, 1, Color(255, 255, 255, 255))

Is there a tutorial on how to make a basic swep for Gmod13?

An example of a swep would work fine as well!

[seanlaff]

I actually got it to work with gui.ScreenToVector (which I'm assuming might not have existed when theJ89 wrote that code block I was using). Anyway I'm drawing the beam it it works perfectly (as in my cursor position is right and the end of it where it hits the terrain) but when I try to set the players eyes to match it, something's off. Hard to describe so here's a picture of where the player is actually aiming (the phys beam). I think it just has to do with the points I'm getting my start positions from but can't quite get it.

[img]https://dl.dropbox.com/u/4636203/aimbeamprob.jpg[/img]

[lua]local vector1 = gui.ScreenToVector( gui.MouseX( ), gui.MouseY( ) )
local traceRes1 = util.QuickTrace( view.origin, vector1 * 5000, ply )
beamend = traceRes1.HitPos

local Vec1 = traceRes1.HitPos -- This is where we are going to look at
local Vec2 = ply:GetEyeTrace().StartPos -- This is where we are
local Ang = (Vec1 - Vec2):Angle() -- Gets the angle between the two points
ply:SetEyeAngles( Ang )[/lua]

It seems to be on the right track, but just ever-so-slightly off.
Try making a few more debug beams to show where the beam (the trace hit) is actually going. That function may not work as advertised.

[koolblue87]

Has anyone ever seen the error "vgui: adding child in layout". It spams when you talk to a npc and their are items in the shop, I narrowed it down to this code where the error appears.

if (!self.ModelPanel) then
			print("before")  -- See if the error appears before this code
			self.ModelPanel = vgui.Create('perp2_trade_inv_item', self:GetParent());  - Error here
			print(self:GetParent()) -- This is here to see is self:GetParent() is null which it is not
			print("after") -- Prints after the error
			self.ModelPanel.trueParent = self;
		end

Yeah that's what I was thinking too but it seems to be pretty spot on with its resultant world coords. The trouble must be with determining the SetEyeAngles
