When I did that it didn't seem to work... I'll try it again some time later. Thanks!

[QUOTE=meowking1;47659378]Hey, I saw a job on scriptfodder where someone was asking how to limit commands for moderators to a certain DarkRP job like "Staff On Duty" so they wouldnt be able to use commands like noclip and godmode while they are roleplaying. How would I do this for my server?[/QUOTE]

Can I hook GM:EntityTakeDamage( target, dmginfo ) ?

Could I hook it as such:

hook.Add( "EntityTakeDamage", "Yo this be my hook son", function( targ, dmg )
    -- My hook function
end )

[editline]5th May 2015[/editline]

Also, I'd be hooking it in a SEnt, and I'll be trying to reduce the damage a player takes.

yes that's how it's done

[WalkingZombie]

Then again, I guess I could just hook it in an initialize script.

I suppose I have another question. Setting an Entity's collision group to [B]11[/B] (which is [B]COLLISION_GROUP_WEAPON[/B]) allows players to walk through them. However,[B] ENTITY:Touch( ent ) [/B]will not be called then. When you walk over a typical SWEP or Weapon, you pick it up automatically. Let's say I was making an Entity that I wanted to function similarly. How would I do that? What hook would run if a player walked through an Entity?

I kinda want it to be performance light, which I believe rules out [B]ents.FindInBox(mins,maxs)
[/B]

How would I use GM:CalcViewModelView to change the position of my SWEP's viewmodel? Just so you know, the name of the view model is models/weapons/c_shotgun.mdl, and the weapon name is simply "shotgun".

return pos, ang

[editline]5th May 2015[/editline]

If you're running the code from the SWEP itself, however, then use this: [URL="http://wiki.garrysmod.com/page/WEAPON/GetViewModelPosition"]SWEP:GetViewModelPosition(pos, ang)[/URL] and again, return pos, ang

Returns this:

I'm not even near the origin of the map.

That gives you a direction, not a position. Shitty example:
[lua]
local vec = gui.ScreenToVector(gui.MousePos())
local tr = util.TraceLine({
start = ply:GetShootPos(),
endpos = ply:GetShootPos() + vec*1e9,
filter = ply
})

Like this?

   function SWEP:GetViewModelPosition( pos, ang )
   Vector(-2.161,0,0.519) return pos
   end

Because, for some reason, this isn't working...

You're not changing the pos variable.

[A Fghtr Pilot]

[QUOTE=Willox;47669966]You're not changing the pos variable.[/QUOTE]

I know what you mean but at the same time I don't... Can you show me what you mean?

[Willox]

You have two options

1)

pos = pos + Vector(-2.161,0,0.519)
return pos

2)

pos:Add( Vector(-2.161,0,0.519) )
return pos

[A Fghtr Pilot]

Thanks! Question, should the SWEP have their view model position changed upon me equipping it, or do I need to change something in SWEP:Think or SWEP:Initialize to get the function called?

I might be late for this, I'm too lazy to read posts :downs:

   function SWEP:GetViewModelPosition( pos, ang )
   pos = Vector(-2.161,0,0.519)

   return pos
   end

[editline]6th May 2015[/editline]

You need to set pos before you return it, in order to change it.

Also, I myself have a question. halo.Add has it's first variable described as a "table of entities". I only have one entity I want to add a halo to, so I'm asking, can I just specify one entity and still have it work?

[zerf]

Literally two posts above. At the halo question, just do {myent}

The function you're hooking is called automatically. If the function is hooked when the SWEP is created, it should be fine.

Also, thank you zerf, and yes... that post was literally two posts lol

I have another question, oh my. How can I find out how deep under water a player is, in units? I understand waterlevel is 0 = what water? 1 = feet, 2 = body, 3 = head, basically... but I want units, to see if maybe a player is 300 units below the top of the water volume.

I've figured out how to color the background by doing

for k, v in pairs( DListView.Lines ) do

etc, however even upon reading the [url="https://github.com/garrynewman/garrysmod/blob/master/garrysmod/lua/vgui/dlistview.lua"]DlistView[/url] I'm unable to work out how to color the line text?
I gather it's something to-do with Columns?

It's all in the skin.

skin.Colours.Label.*[Default|Bright|Dark|Highlight]

This is performed in the DListView_Line's "DListViewLabel" panel:
[lua]
function PANEL:UpdateColours( skin )

if ( self:GetParent():IsLineSelected() ) then return self:SetTextStyleColor( skin.Colours.Label.Bright ) end

return self:SetTextStyleColor( skin.Colours.Label.Dark )

end
[/lua]
Which, "SetTextStyleColor" comes from the DLabel panel.

are there any limitations regarding the PlayerDisconnected hook that I don't know about?

im running a local SRCDs server to test/develop. im writing stuff to a database and want it to save a player's current data when they leave, like so:

function PlayerDisconnected( ply )
	doStuff( ply )
end
hook.Add( "PlayerDisconnected", "dostuff", doStuff )

when i disconnect from my server it complains that ply is nil, not sure if its something to do with the server being local since i never had any problems doing it this way in the past.

*edit*

nevermind, i updated some functions and forgot to amend the extra ply argument to them all.

The code you provided seems to generate this error when someone tries to use the remover tool on anything, not just cars. It also seems to prevent the remover tool from working on cars altogether.

This is the code that I am running in garrysmod/lua/autorun/server (the only things changed are the single equals to double equals, and the comments.)

[lua]
-- Code by Busan1 on facepunch

local function canDoStuffWithCar( _e )
if( _e:GetDriver() && _e:GetDriver():IsPlayer() ) then
return false;
end
return true;
end

hook.Add( "CanTool", "SomeUniqueHookName999", function( _p, _e, tool ) -- Remover restriction
if( tool == "remover" && _e:IsVehicle() && !canDoStuffWithCar( _e ) ) then
return false;
end
end );

hook.Add( "PhysgunPickup", "SomeUniqueHookName666", function( _p, _e ) -- Physgun restriction.

if(_e:IsVehicle() && !canDoStuffWithCar( _e ) ) then
return false;
end
end );
[/lua]

Is there something simple I overlooked when testing?

what error are you getting? the only thing i would suspect from looking at it is that the '!canDoStuffWithCar ( _e )' function is being called on every entity that is shot, but GetDriver() will only work on vehicle entities. im not sure if lua tries to evaluate everything in an if statement or drops it at the first false, though, so i could be way off.

-- Code by Busan1 on facepunch

local function canDoStuffWithCar( _e )
    if( _e:GetDriver() && _e:GetDriver():IsPlayer() ) then
        return false;
    end
    return true;
end

hook.Add( "CanTool", "SomeUniqueHookName999", function( _p, _e, tool ) -- Remover restriction
    if( tool == "remover" && _e:IsVehicle()) then
        if (!canDoStuffWithCar( _e )) then return false; end
    end
end );

hook.Add( "PhysgunPickup", "SomeUniqueHookName666", function( _p, _e ) -- Physgun restriction.

    if(_e:IsVehicle())  then
        if (!canDoStuffWithCar( _e )) then return false; end
    end
end );

if the error is something along the lines of [b]attempt to call method 'GetDriver' (a nil value)[/b] then this should work.

*edit*

just read up that they do use short cut evaluation, so the above probably isnt the solution.

How would I, with GM:CalcView()(or SWEP:CalcView(), in this case), make a viewbob code?

[Mrkrabz]

[QUOTE=A Fghtr Pilot;47679640]How would I, with GM:CalcView()(or SWEP:CalcView(), in this case), make a viewbob code?[/QUOTE]

[lua]ViewBobAng = 0

angles.yaw = angles.yaw + math.cos( ViewBobAng ) * 0.3

hook.Add( "CalcView", "ViewBob", ViewBob )[/lua]

You sure calling CalcView would be better? Probably would be better to use SWEP:CalcView, I'm not trying to add viewbob to all weapons, I'm trying to add viewbob purely to my weapon. Also, it doesn't work when I change it to SWEP:CalcView and remove hook.Add.

You need to return the arguments for it to affect CalcView

How can I find out how deep under water a player is, in units? I understand waterlevel is 0 = what water? 1 = feet, 2 = body, 3 = head, basically... but I want units, for example, to see if maybe a player is 300 units below the surface.

I'd suggest saving the z pos of the player at waterlevel 1, then compare that to the player's z pos when they are waterlevel 3 that will give you units from the feet depth (basically surface).

hope this helps

How do I convert a color table to player color?

As far as I understand it, player color should be a vector with R, G, B values between 0 and 1, but a color table is a table with R G B A values between 0 and 255. So I think I need to take the first 3 values, divide them by 255, and turn it into a vector.. But how?
