[QUOTE=James xX;47621551]Do you already have the entity or are you searching for it? If you already have it, some maths on the individual coordinates of the vectors should provide some help (Higher level of maths than I ever bothered to understand, so you will have to ask someone who is studying maths at university). But to answer your question, yes, it's more than possible.[/QUOTE]

You can't do that with a series of points alone. You need to define edges between them and then faces between the edges.

The points could define a convex hull though. Either way I have no idea how to intersect a convex hull with another convex hull efficiently, even if one of them is an AABB. The internet probably knows.

EDIT: interpreting it as a convex hull is equivalent to implicitly defining edges and faces I guess

That's what I meant. In my head, the way I would do it is get the connecting vectors in series, and calculate a virtual gradient and intercept for a function of a line that crosses the points. Once all the line functions have been calculated, get the position of the entity, and check (with the x,y and z component), which line functions to use (one on either side per dimension). That way, you are only doing 6 comparisons. If all return true, then it is within the defined boundary.

What would be the most efficient way for me to network data for an entity, i currently use ent:SetNWVar which i know is terrible, so advice on something that is more efficient for the server would be great. The data would be getting updated now and then but i need it to stay synchronized between server and client.

I have looked at entity data tables however it would error when i try to call the getX function for the entity

I'd look into creating my own networked var style of method of doing it, using the net library.

Okay will do, if i feel that the code is good enough and if it actually works i will release it for others to use :)

I have made a small script that adds a play count tally for the map currently being played to a database but I am having trouble calling the function again when the map changes.

At the moment I am using the Initialize hook, which works great on server start but does not get called again when the map changes. Looking through the wiki, I seem to be overseeing the hook I need.

So my question, is there a hook that can be called every time the server changes map but at a point where it can read game.GetMap()?

Try printing something on initpostentity and see if that works, if it does then it's a problem with your mysqloo code.

When the map changes, players are not asked to reconnect or even to be re-authenticated. This means that you need to keep track of players who join and leave right from the beginning.

Using the following code:

[lua]
local fmt = "[%s] %s has connected.";

gameevent.Listen("player_connect");
hook.Add("player_connect", "player_connect", function(data)
print(string.format(fmt, "player_connect", data.name));
end)

hook.Add("CheckPassword", "CheckPassword", function(steamID64, ipAddress, svPassword, clPassword, name)
print(string.format(fmt, "CheckPassword", name));
end);

hook.Add("PlayerAuthed", "PlayerAuthed", function(ply, steamid, uniqueid)
print(string.format(fmt, "PlayerAuthed", ply:Name()));
end);

hook.Add("PlayerConnect", "PlayerConnect", function(name, ip)
print(string.format(fmt, "PlayerConnect", name));
end);

hook.Add("PlayerInitialSpawn", "PlayerInitialSpawn", function(ply)
print(string.format(fmt, "PlayerInitialSpawn", ply:Name()));
end);

hook.Add("InitPostEntity", "InitPostEntity", function()
print("[InitPostEntity] Called");
for k,v in pairs(player.GetAll()) do
print("\tJoining player: " .. v:Name());
end
end);
[/lua]

This is the order in which the hooks are called:

- ServerBoot -
+ InitPostEntity
+ CheckPassword
+ PlayerConnect
+ player_connect
+ PlayerInitialSpawn
+ PlayerAuthed

- Changemap -
+ InitPostEntity
+ PlayerInitialSpawn
+ PlayerAuthed

The only way I know of to track connected players after a map change is to hook into PlayerConnect/PlayerDisconnected (Or the game events) and use those.

It should go without saying (Since players are not asked to reconnect), players are not disconnected on a map change.

How do I correctly offset an angle? I posted some of my code in a help thread about hats, and I remembered that my angle offsets were acting funky. This is the code I am using:

[lua]
ang:RotateAroundAxis(ang:Right(), self.Offset[index].Angle.r);
ang:RotateAroundAxis(ang:Up(), self.Offset[index].Angle.p);
ang:RotateAroundAxis(ang:Forward(), self.Offset[index].Angle.y);
[/lua]

Where an example offset for the model "models/props_2fort/hardhat001.mdl" would be Angle(90,0,-90). The problem is, the yaw member offsets in the same plane as the pitch member, which to me isn't always a problem, but obviously needs to be fixed. Can anyone provide some insight on how to add an offset to an angle correctly? Thanks.

solved: For anyone wondering, it was the order in which I was editing the angle:

[lua]
ang:RotateAroundAxis(ang:Up(), self.OffsetAngle.p);
ang:RotateAroundAxis(ang:Forward(), self.OffsetAngle.y);
ang:RotateAroundAxis(ang:Right(), self.OffsetAngle.r);
[/lua]

Thank you both very much for your help.

Turns out that mysqloo was not calling the function again when the map was changed. I figured this might be the case as the module uses the Think hook, which was not getting called again until a player connected.

What I did to combat this is using the information that G4MB!T provided, I changed my script to look like this.

[lua]function MapCount()
if #player.GetAll() == 1 then
[mysqloo code here]
end
end

hook.Add( "PlayerInitialSpawn", "mapCount2DB", mapCount )[/lua]

This means the function would be called when anyone would connect but would only be called when the player count is at 1 player. It has its flaws like it would still be called if the server had only one player and they disconnect/reconnect it would poll on the database for the map being played but it's a minor one.

Any way I could improve this you think? Thanks again for your help though :)

I thought you were storing the amount of players on the current map? If so then wouldnt you want to update it whenever someone joins or leaves?

I want to use this simple ulx voting command to switch gamemodes by activating an rcon command doing "gamemode {insert gamemode here}". It is on the server properly, and the vote shows up, yet at the end it doesnt switch the gamemode or let alone give any feedback.

	ulx.doVote( title, { ... }, voteDone )
	ulx.fancyLogAdmin( calling_ply, "#A started a vote (#s)", title )
end
