Problems That Don't Need Their Own Thread v5

[Geferon]

[QUOTE=Castiel789;52656839]Sorry if this is the wrong place to be asking this, but my servers (ran from a dedicated server) seem to be 50/50 on whether or not they connect to the steam servers when they boot:

"Could not establish connection to Steam servers. (Result = 3)"

Changing port etc seems to do nothing, and googled answers seem either irrelevant due to the person's server ALWAYS doing it, or it simply doesn't fix it. Any help is greatly appreciated.[/QUOTE]

This happened to me due to the server having multiple IPs due to one Virtual Box inside of the dedicated server.
Try starting the server with the +ip command with the local network address of the server.

Was there a change to how PrintTable works, or have I managed to install an addon that broke PrintTable?

local tbl = {
	["last_stamina_use"] = CurTime(),
	["stamina"] = 0,
}
print("tbl was", tbl)
PrintTable(tbl)
timer.Simple(0,function()
	print("tbl is now",tbl)
	PrintTable(tbl)
end)

tbl was	table: 0x5e4bf1c8
last_stamina_use	=	7317.59765625
stamina	=	0
tbl is now	table: 0x5e4bf1c8
-- <- The table should be re-printed here.

local function loltable(tbl)
	for k,v in pairs(tbl) do print(k,":",v) end
end

local tbl = {
	["last_stamina_use"] = CurTime(),
	["stamina"] = 0,
}
print("tbl was", tbl)
loltable(tbl)
timer.Simple(0,function()
	print("tbl is now",tbl)
	loltable(tbl)
end)

tbl was	table: 0x526e9d90

How do I use a key to get the value in a table. for example a table with 3 values and i want the value of the 2nd key how would i do this

Not sure where the best place is to ask about this is, but anyway I had someone come on my server and cause it to lag to the point where it completely froze, they were standing there doing nothing and all I saw in the server console was something along the lines of ' Unknown command 'ECKSDEE' ' :p

Is this some simple security problem I can fix up?

[G😹nz😻]

Yeah, you got backdoors, you would need to find a backdoor checker script, i'm not sure if it's on workshop

[QUOTE=gonzalolog;52661050]Yeah, you got backdoors, you would need to find a backdoor checker script, i'm not sure if it's on workshop[/QUOTE]

I'm pretty sure there's cheats that just have a way of spamming the server console with unknown commands. I don't think that part is a backdoor.

I have a problem where NPCs that use a SWEP will end up T-Posing while firing. I've set the capabilities and I know for sure the model has the animation ( Combine Super with AR2, Soldier with SMG, etc )

[G4MB!T]

It could be that the SWEP you are using doesnt have translations to AI activities. Usually SWEPs and weapon bases targetted for players dont provide them.

[QUOTE=G4MB!T;52663213]It could be that the SWEP you are using doesnt have translations to AI activities. Usually SWEPs and weapon bases targetted for players dont provide them.[/QUOTE]

The swep is derived from the weapon_base so it should have all the animations translated already. I tried moving the translation functions into the base file just for posterity but it still yields them being tposed when firing

Anyone know why I can't resize anything sprayed with [img]http://wiki.garrysmod.com/favicon.ico[/img] [url=http://wiki.garrysmod.com/page/util/DecalEx]util.DecalEx[/url]?

This is a decal with the size of 1000,1000:

And one with 0,0 (But I set the texture to white):

Is it possible that they span over 2 different brushes? Maybe try it with a power 2 size.

Anyone know the best way to get information from the mouse? I need to get info from the mouse without changing the players eye angles? Someone mentioned [img]http://wiki.garrysmod.com/favicon.ico[/img] [url=http://wiki.garrysmod.com/page/GM/CalcView]GM:CalcView[/url], bit I don't quite understand how to get mouse movements from that cleanly and efficiently. Can someone point me in the right direction?

This sounds like an XY problem to me. What are you trying to do?

[QUOTE=txike;52667437]This sounds like an XY problem to me. What are you trying to do?[/QUOTE]

Messing around with vehicles. I want the vehicle to change angles and move based on mouse movement while the players view is locked. I need input from the mouse (as in actual mouse movement), but not sure how to go about getting it. There seems to be no hook for it or anything like that.

Alright so I'm attempting to draw a circle on the map; which works all fine but the issue is that you can't see the circle once you're inside of it, how can I make it render?

hook.Add("PostDrawOpaqueRenderables", "circletest", function()
	render.SetColorMaterial()
	render.DrawSphere(LocalPlayer():GetPos(), 1000, 30, 30, Color(255,255,255,50))
end)

One way is to draw the circle inside-out by giving it negative radius

hook.Add("PostDrawOpaqueRenderables", "circletest", function()
        render.SetColorMaterial()
        render.DrawSphere(LocalPlayer():GetPos(), 1000, 30, 30, Color(255,255,255,50))
        render.DrawSphere(LocalPlayer():GetPos(), -1000, 30, 30, Color(255,255,255,50))
end)

There's probably a "right" way to do it by applying a material that draws on both faces or something.

Is there any way to perform a trace through a wall to get the position of the other side of the wall?
I seem to remember someone doing it for some teleportation thing in an old WAYWO.

There is no clean way to do this -- you have to step through arbitrarily until you find a clear position. Here's an excerpt from some bullet penetration code:

-- Config
local flExitMaxDistance = 128 -- Max distance before giving up
local flExitStepSize = 24 -- Step size
local iMask = MASK_SOLID
local bShowPenetration = true
local DEBUG_LENGTH = 3
local color_altdebug = SERVER and Color(0, 255, 0, 128) or Color(255, 255, 0, 128)


-- Penetration
local vHitPos = -- Position to test from
local vShotDir = -- Ray (normal vector) to trace along
local flExitDistance = 0

local tr = {}
local tTrace = {
	mask = iMask,
	filter = tEnts,
	output = tr
}

// try to penetrate object, maximum penetration is 128 inch
while (flExitDistance < flExitMaxDistance) do
	flExitDistance = math.min(flExitMaxDistance, flExitDistance + flExitStepSize)
	
	local vHit = vHitPos + flExitDistance * vShotDir
	tTrace.start = vHit
	tTrace.endpos = vHit
	util.TraceLine(tTrace)
	
	if (not tr.Hit) then
		// found first free point
		goto PositionFound
	end
end

-- Nowhere to penetrate
do return end

::PositionFound::

tTrace.endpos = vHitPos
util.TraceLine(tTrace)

local vOtherSide = tr.HitPos -- This is your result

if (bShowPenetration) then
	debugoverlay.Line(vHitPos, vOtherSide, DEBUG_LENGTH, color_altdebug)
end

[QUOTE=code_gs;52670254]There is no clean way to do this[/QUOTE]

Can't you just perform one trace forward to hit the wall, one through the wall, and one back so you hit the wall?
This seems to work:

local function BackSide( src, dir, distance )
	local tr = util.TraceLine( { -- trace through the wall
		start = src + dir,
		endpos = src + dir * distance,
		mask = MASK_SOLID_BRUSHONLY
	} )
	local tr2 = util.TraceLine( { -- trace back to hit the back of the wall
		start = tr.HitPos,
		endpos = tr.HitPos - tr.Normal * distance,
		mask = MASK_SOLID_BRUSHONLY
	} )
	return tr2 -- seems to actually work
end

hook.Add( "EntityFireBullets", "TraceTest", function( ent, data )
	local tr = util.TraceLine( { -- trace until you hit the front of the wall
		start = data.Src,
		endpos = data.Src + data.Dir * data.Distance,
		mask = MASK_SOLID_BRUSHONLY
	} )
	local tr2 = BackSide( tr.HitPos, tr.Normal, data.Distance )
	ent:SetPos(tr2.HitPos)
	debugoverlay.Sphere( tr2.HitPos, 100, 10, Color( 255, 0, 0 ) )
end )

Erm.. This is a client side function. I need the server to be constantly updating the angles, so would I just send the server the information every tick via net messages? That sounds disgusting though. Would that slow down the server significantly? Seems like I have no other choice. :/

You're correct, that does actually work a lot better -- I didn't know space between brushes was empty. Make sure to use ents.GetAll for the filter so you don't run into anything while working with the world.
