Well I don't have it installed in my addons so I'm not sure.
And I heard it ships with gmod now anyway

99% sure it doesn't, did you check both legacy addons (stored in the old addons/ folder) and workshop addons? It might also be somewhere in your lua folder if you installed it that way

Is there such a thing as a hook that is called when a table changes?

[vinylrain]

How can I scan through an array to find data and then do something with that? For example:
[LUA]
if ply:Name() --[is inside]-- == list_of_names[] --[this array]-- then
--Do something
end[/LUA]

__newindex is called when writing a value with a key that is not already present in the table.
__index is called in every other situation (when reading from or writing to the table)

EDIT: Ninja'd. However, the guy before me is slightly wrong, since __newindex doesn't work as you'd expect. It isn't called when writing a key that already exists.

I'm struggling to understand from the reference documentation, could you give me a basic example?
bear in mind I'm very low level coding.

Am I right in thinking that the function is called through hook.Add but then it waits for a change before continuing?
Where does this __newindex go exactly?

It's not a hook, you apply the __methods to the table you want to monitor.

[Bilsta1000]

In my case I'm trying to monitor how many players are within a specific box.
So it needs to look like this? or am I just not getting it.

[lua]PVPPlayers.__newindex = ents.FindInBox( Vector(9004.761719, -3845.509277, 5487.840332), Vector(16267.462891, -9213.438477, 2983.771729))[/lua]

[Divran]

[lua]local metatable = {
__newindex = function( tbl, key, value )
print("something has been added to " .. tostring(tbl) .. " at " .. tostring(key) .. " with value " .. tostring(value))
rawset( tbl, key, value ) -- set the value
end,
__index = function( tbl, key )
print("something has been accessed from " .. tostring(tbl) .. " at " .. tostring(key))
return rawget( tbl, key ) -- return the value
end,
}

local mytable = {}
setmetatable(mytable,metatable)[/lua]

EDIT: I tested the above code in SciTE, and found the following:
[lua]mytable.stuff = "hax" -- will call metatable.__newindex with the table "mytable", key "stuff" and value "hax"
print(mytable.stuff) -- won't call any function
mytable.stuff = "asdasdasd" -- won't call any function
print(mytable.asdsd) -- will call __index[/lua]
it's a bit strange, but that's how it works.

[Bilsta1000]

[lua]local metatable = {
__newindex = function( tbl, key, value )
print("something has been added to " .. tostring(tbl) .. " at " .. tostring(key) .. " with value " .. tostring(value))
GiveNewPlayerGuns()
end,
__index = function( tbl, key )
print("something has been accessed from " .. tostring(tbl) " at " .. tostring(key))
end,
}

local PVPPlayers = {}
setmetatable(PVPPlayers,metatable)

PVPPlayers = ents.FindInBox( Vector(9004.761719, -3845.509277, 5487.840332), Vector(16267.462891, -9213.438477, 2983.771729))[/lua]

Tried adding the code to mine.
So everytime a new player enters the defined box the value will change and the GiveNewPlayerGuns() function will run....... right?

[Adult]

Quick question, is there a difference between Player.tbl and Player:GetTable().tbl?

[Matt-]

[QUOTE=Bilsta1000;39341328]So everytime a new player enters the defined box the value will change and the GiveNewPlayerGuns() function will run....... right?[/QUOTE]

Nope, ents.FindInBox is only run once and returns a table. You said you do low-level programming, so if it makes more sense this way: it's not a pointer. ents.FindInBox has to be called each time you want to check entities in a box.

[editline]24th January 2013[/editline]

[QUOTE=Adult;39341467]Quick question, is there a difference between Player.tbl and Player:GetTable().tbl?[/QUOTE]

Yes they're the same, however Entity:GetTable() is now deprecated, it's very much advised you don't use it. It was around before you were able to apply variables directly to Entity objects.

[Bilsta1000]

Then what would you advise if I wanted to run a function every time another player entered the box?

They teleport in there using the hammer entity if that helps.

[QUOTE=Bilsta1000;39341858]Then what would you advise if I wanted to run a function every time another player entered the box?[/QUOTE]

It's quite a heavy function, but hmm. Try the "Tick" hook, unless somebody else can come up with a better hook.

Is there any way of checking which way a person entered/exited the tunnel and the direction they travel in?

Doesn't work, I have a similar problem.

I managed to block entities and weapons being spawned like this, but not vehicles.

I set the max to 0 but that makes Car Dealer a pointless job, I only want to block that damned creator tool. >.>

[Matt-]

[QUOTE=Science;39342094]Lets say i had a tunnel.

Check players distance from the center of the tunnel, when they come in range take the starting position and when they're out of range take the end position. Then do a bit of simple math to work out the direction.
