So, like only draw the model when it is beneath/touching the ground?

Draw the model when it is beneath and above.

I'm having trouble getting my crossbow SWEP's bolt to deliver damage properly:

function SWEP:PrimaryAttack()
    if !self:CanPrimaryAttack() then return end
    self:SetNextPrimaryFire(CurTime() + 0.75)
    if SERVER then
        local Bolt = ents.Create("crossbow_bolt")
        if !IsValid(Bolt) then return end
        Bolt:SetPos(self.Owner:GetShootPos() + self.Owner:EyeAngles():Forward()*50 - self.Owner:EyeAngles():Up()*3 + self.Owner:EyeAngles():Right()*3)
        Bolt:SetAngles(self.Owner:EyeAngles()) --[[* self.Owner:GetEyeTrace().Fraction*2000]]
        Bolt:Spawn()
        Bolt:SetOwner(self.Owner)
        Bolt:SetVelocity(Bolt:GetAngles():Forward()*3447.2)
        Bolt.SetPhysicsAttacker(self.Owner)
        Bolt.m_iDamage = 100
    end
end

Entities hit by it call OnTakeDamage(), I think it's just set to 0. If anyone could tell me how exactly I can set damage properly, and hopefully have it punt physical props, that'd be awesome. Thanks.

If I'm not mistaken, crossbow_bolt is the Source entity for it. What I would recommend is making your own bolt swep, then on the ENT:Touch method, check if the entity it touched is a player. If it is, checked GM:PlayerShouldTakeDamage and if it succeeds, call GM:EntityTakeDamage with the entity it touched and make your own DamageInfo to pass to it.

It might help to read Valve's code for the bolt, but it's in C++ which is a LOT harder to read than Lua. [url]https://github.com/ValveSoftware/source-sdk-2013/blob/master/mp/src/game/server/hl2/weapon_crossbow.cpp[/url]

I've been trying to get a detoured function to not happen twice/thrice/four times every time I update a file and cause a lua autorefresh. My code:

[lua]local oldfunc = undo.Finish

--[[------------------------------------------------------------------------------
Catch undos - call the UndoCaught hook when a player did any undoable action.
---------------------------------------------------------------------------------]]
function undo.Finish()
local OUT = {} -- OUT = Old Undo Table
for uid, undos in pairs(undo.GetTable() ) do
OUT[uid] = table.GetKeys(undos)
end

oldfunc() -- Do the ACTUAL undo.Finish()

local CUT = undo.GetTable() -- CUT = Current Undo Table
for uid, undos in pairs(CUT) do
for undokey, undodata in pairs(undos) do
if !OUT[uid] or !table.HasValue(OUT[uid], undokey) then hook.Run( "UndoCaught", uid, undokey, undodata ) end
end
end
end[/lua]

This works great, except it calls UndoCaught more than once depending on how many times lua has autorefreshed.

What's the cleanest way to solve it? I've thought of making some global variable (like UndoCatcherDone = true) and checking it BEFORE doing this, but that's a bit ugly. (pun not intended but is awesome)

Something like this should work.

OldUndoFinish = OldUndoFinish or undo.Finish

That way the old function is stored and not updated ever time the file reloads.

Anyone know of any good tutorials or explanations on how to make 3D2D HUDs?

[Bobblehead]

[QUOTE=Zachy;47199315]Anyone know of any good tutorials or explanations on how to make 3D2D HUDs?[/QUOTE]

A quick rundown is as simple as 1, 2, 3:

1) Determine how many planes you want. Usually you will want two; one on the left and one on the right for armor/health and ammo, respectively.

2) For each plane, create a 3D2D clause using cam.Start3D2D() and cam.End3D2D(). The position should be offset from the player's EyePos(). It should be rotated based on their EyeAngles().

3) Inside each clause, draw your HUD like you would draw it normally.

Why does table.ForEach exist?
[QUOTE=Author.;47199982][lua]> table.ForEach( {"potatoes", 1337, {4, 2, 0}}, function(k, v) print(k, v) end)...
1 potatoes
2 1337
3 table: 0x26a2d098[/lua]

Just a cleaner way to iterate through tables I guess?[/QUOTE]

I would argue it's less clean than a for loop. Looking at the source, it's simply one unneeded function call then one unneeded function call per loop:
[lua]
function table.ForEach( tab, funcname )

for k, v in pairs( tab ) do
funcname( k, v )
end

end
[/lua]

[QUOTE=bobbleheadbob;47199996]
Well the uncapitalized version is the old way to iterate a table, deprecated and replaced by iteration functions like pairs().

The one with UpperCamelCase says this on the wiki:

If table.foreach()'s callback function returns anything, the loop is broken. This is how we broke loops before the break keyword came into play.
[/QUOTE]
Since it seems like the capitalized version was never and is never needed, perhaps deprecation should be issued?

[Author.]

Just a cleaner way to iterate through tables I guess? Don't forget table.foreach is a deprecated function, which I'm guessing is the main reason for it's existance.

I really really bothers me when people use pairs over ipairs.

[helix757]

Is there any other documentation on a scroll menu rather than the TTT one?

[Bobblehead]

[QUOTE=StonedPenguin;47200402]I really really bothers me when people use pairs over ipairs.[/QUOTE]

It was tested and someone found out that ipairs is actually slower by the smallest fraction.
It's only useful for intentional sorting.

Does the loading screen HTML panel support HTML5?

[ROFLBURGER]

I have a clientside script that adds somes of viewpunch based on acceleration. This is the code I have so far.

function HandleAcceleration(ply)

	if not ply.NewAcceleration then
		ply.NewAcceleration = Vector(0,0,0)
	end
			
	if not ply.OldAcceleration then
		ply.OldAcceleration = Vector(0,0,0)
	end
	
	if not ply.LastAngle then
		ply.LastAngle = ply:EyeAngles()
	end

	ply.NewAcceleration = WorldToLocal(ply:GetVelocity(),Angle(0,0,0),Vector(0,0,0),ply:GetAngles())
	
	local nx = ply.NewAcceleration.x
	local ny = ply.NewAcceleration.y
	local nz = ply.NewAcceleration.z
	
	local ox = ply.OldAcceleration.x
	local oy = ply.OldAcceleration.y
	local oz = ply.OldAcceleration.z
	
	ply.OldAcceleration = WorldToLocal(ply:GetVelocity(),Angle(0,0,0),Vector(0,0,0),ply:GetAngles())
	
	local Result = Angle( (-(nx - ox) / 100) + ((nz - oz) / 100) ,0, -(ny - oy) / 100 )
			
	if Result ~= Angle(0,0,0) then
		
		if ply.PunchAmount then
			ply.PunchAmount = ply.PunchAmount + Result
		else
			ply.PunchAmount = Result
		end
		
	end
	
	if ply.PunchAmount then
		ply.OldAngle = ply:EyeAngles() - ply.PunchAmount
	
		local Amount = 2*FrameTime()
	
		local PClamp
		local YClamp
		local RClamp
	
		if ply.PunchAmount.p > 0 then
			PClamp = math.max(0,ply.PunchAmount.p - Amount)
		elseif ply.PunchAmount.p < 0 then
			PClamp = math.min(0,ply.PunchAmount.p + Amount)
		else
			PClamp = 0
		end
		
		if ply.PunchAmount.y > 0 then
			YClamp = math.max(0,ply.PunchAmount.y - Amount)
		elseif ply.PunchAmount.y < 0 then
			YClamp = math.min(0,ply.PunchAmount.y + Amount)
		else
			YClamp = 0
		end
		
		if ply.PunchAmount.r > 0 then
			RClamp = math.max(0,ply.PunchAmount.r - Amount)
		elseif ply.PunchAmount.r < 0 then
			RClamp = math.min(0,ply.PunchAmount.r + Amount)
		else
			RClamp = 0
		end		
	
		ply.PunchAmount = Angle(PClamp,YClamp,RClamp)
		
	else
		ply.OldAngle = ply:EyeAngles()
	end
	
	local Test = ply.PunchAmount
	
	if Test ~= Angle(0,0,0) then
		print(Test)
	end
	
	local Difference = ply:EyeAngles() - ply.LastAngle + Test

	ply:SetEyeAngles( ply:EyeAngles() )
	
	ply.LastAngle = ply:EyeAngles()
	

end

I'm stuck on actually putting everything together, so it sets the view based on ply.PunchAmount

ie if ply.PunchAmount is Angle(1,0,0), then it would set the EyeAngles Pitch to 1 degree over what it should normally be.

[Ott]

Just stick it in a CalcView hook and override aim angles.

[QUOTE=Acecool;47125595]Are you just trying to angle the ends, or make it rise / fall? With poly it's simply connect the dots without allowing the lines to cross.

Here's an example of a simple angled bar ( using easy input of x, y, w, h and tilt-shift amount ):

I managed to almost fully get what I want but I feel like my calculations are off. Whenever I put in 90 degrees for the angle it won't draw the polygons. Also whenever I try to do certain angles it will not work correctly.

I am trying to make things like the health bar, ammo bar, and hud panels face inward towards the center of the screen.

Thank you, detouring definitely looks promising. I guess a follow up question would be if there's any quick way to load my lua script first on the client before they load up any other addons/lua files?

There are ways a client can modify any lua file you send them before they're ran. However, only 3 people have reported the exploit, so it's pretty unknown. I'd assume that gamemode and lua/ code is ran before addon code is, though.

[Acecool]

Actually, addons are loaded prior to GM being set ( which is why if you want to create new GM functions, you need to do so in a hook such as Initialize )...

Gamemode is loaded next.

Lua/ may be loaded first or maybe at the same time as addons because addons load into GMod as virtual directories...

I'm running dev-mode.

You should have no trouble using 3D2D and rotating the panels out... This way you can simply create the panels on a flat surface then rotate them out; it'll make the code easier to follow, easier to alter, etc...

I'm having trouble sorting a table by more than one member.

My test code:
[lua]local tab = {
{one = 2, two = 1},
{one = 3, two = 2},
{one = 1, two = 3},
{one = 2, two = 1},
{one = 3, two = 2},
{one = 3, two = 3},
{one = 3, two = 1},
{one = 1, two = 2},
{one = 2, two = 3},
}

print("\nBefore SortByMember:")
PrintTable(tab)

table.SortByMember(tab, "one")

print("\nAfter Sort By One:")
PrintTable(tab)

table.SortByMember(tab, "two")

print("\nAfter Sort By Two:")
PrintTable(tab)[/lua]

The results:

Before SortByMember:
1:
		one	=	2
		two	=	1
2:
		one	=	3
		two	=	2
3:
		one	=	1
		two	=	3
4:
		one	=	2
		two	=	1
5:
		one	=	3
		two	=	2
6:
		one	=	3
		two	=	3
7:
		one	=	3
		two	=	1
8:
		one	=	1
		two	=	2
9:
		one	=	2
		two	=	3

After Sort By One:
1:
		one	=	3
		two	=	2
2:
		one	=	3
		two	=	1
3:
		one	=	3
		two	=	2
4:
		one	=	3
		two	=	3
5:
		one	=	2
		two	=	1
6:
		one	=	2
		two	=	1
7:
		one	=	2
		two	=	3
8:
		one	=	1
		two	=	2
9:
		one	=	1
		two	=	3

After Sort By Two:
1:
		one	=	1
		two	=	3
2:
		one	=	2
		two	=	3
3:
		one	=	3
		two	=	3
4:
		one	=	1
		two	=	2
5:
		one	=	3
		two	=	2
6:
		one	=	3
		two	=	2
7:
		one	=	2
		two	=	1
8:
		one	=	3
		two	=	1
9:
		one	=	2
		two	=	1

As can be seen, the first sort is essentially lost in the second one. I'd have expected it to be preserved when two values are the same.
What's going on, and do I have to write my own sort function? :suicide:
