[QUOTE=MaxShadow;49670741]I always store all ordered npcs into a table, and then I use a constant timer to check if they are at a certain distance from their target position in a for loop.[/QUOTE]

OK, cool. I wonder if doing that slows or lags anything

[Mrkrabz]

WithinAABox seems to always be returning false, I had it working on a past map but cannot get it working now.

[lua]
local Start = Vector(-10919.388672, 14790.270508, 10046.089844)
local Start1 = Vector(-10513.226563, 13777.234375, 9441.031250)
if v:GetPos():WithinAABox(Start, Start1) then
print("yes")
else
print("no")
end
[/lua]

Players position is "-10735.693359 13976.206055 9504.031250" which afaik is in between those two vectors?

If I had to guess how the function worked I'd say it's because the y and z vectors are bigger on the first vector than on the second

Ah good point, didn't even think of that.

Edit: Shouldn't ents.FindInBox act the same way if that is the case? As it works fine.

I had the same thought in my failed attempt of using WithinAABox. The wiki does name the arguments different in the two functions though. If you have any luck, please let me know!

Is there a way to remove an effect prematurely? As far as I know, the functions used to create effects don't return a reference to them.

Wondering about this myself as well.

[jd0124]

How can I get my scripted NPC to spawn standing still until I give it somewhere to move?

I've got a scripted NPC based off the npc_shop example. I gave it the capability of walking with this:

self:CapabilitiesAdd( CAP_MOVE_GROUND )

But now when it spawns it automatically wanders off randomly around the whole map.

I tried both of these in ENT:Initialize() but they didn't do anything.

self:SetSchedule(SCHED_NONE)

and

self:SetSchedule(SCHED_IDLE_STAND)

[Windwhistle]

On a map change, this code...

local chatcommands = {};

function GAMEMODE:PlayerSay(ply, text, teamc, alive)
	local chat_string = string.Explode(" ", text);
	
	for k, v in pairs( chatcommands ) do
		if( chat_string[1] == k ) then
			table.remove(chat_string, 1);
			v(ply, chat_string);
			
			return "";
		end
		
		if( string.find(k, chat_string[1]) != nil ) then
			local start, endp, word = string.find(k, chat_string[1]);
			
			if( endp - (start - 1) > 2 ) then
				ply:ChatPrint("Invalid command! Did you mean '"..tostring( k ).."'?");
				
				return "";
			end
		end
	end
	
	return text;
end

function RegisterChatCommand(strCommand, Func)
	if( !strCommand || !Func ) then return; end
	
	for k, v in pairs( chatcommands ) do
		if( strCommand == k ) then
			return;
		end
	end
	
	chatcommands[ tostring( strCommand ) ] = Func;
end

-- Chat commands

-- Test command
RegisterChatCommand("!fuckyou", function(ply, args)
	if( ply:IsSuperAdmin() ) then
		local pname = args[1];

		for _, v in pairs( player.GetAll() ) do
			if( string.find(v:Nick(), pname) ) then
				v:ChatPrint("Hey man, fuck you.");
			end
		end
	end
end)

-- Screengrab
RegisterChatCommand("!screengrab", function(ply, args)
	if ply:IsSuperAdmin() then
		ply:ConCommand("screengrab")
	end
end)

...will no longer work and spew out this error in console:

You have to use a hook instead of replacing the gamemode's default hook.
Use [img]http://wiki.garrysmod.com/favicon.ico[/img] [url=http://wiki.garrysmod.com/page/hook/Add]hook.Add[/url] instead.

The arguments for WithinAABox are min and max, so each x, y and z for min must be <= max's corresponding axis.

Makes it a little difficult to use, but it does work.

It has to be in the right order on x/y/z based on world orientation too
is there a function that fixes this when inputting two vectors? always a pain to get it right

I still can't find a solution to this. I found that if I override ENT:SetSchedule like this:

function ENT:SelectSchedule(iNPCState )

end

then the NPC doesn't walk at the start, but then I can't get it to walk anywhere.

save the base method ENT.SelectSchedule then in whichever way you want, call that function to make it walk

You could do this:

[lua]
local function GetMinMax(a, b)
local min = Vector(0, 0, 0);
local max = Vector(0, 0, 0);

for i = 1, 3 do
if (a[i] >= b[i]) then
max[i] = a[i];
min[i] = b[i];
else
max[i] = b[i];
min[i] = a[i];
end
end

return min, max;
end

I'm trying to use [img]http://wiki.garrysmod.com/favicon.ico[/img] [url=http://wiki.garrysmod.com/page/GM/HandlePlayerJumping]GM/HandlePlayerJumping[/url] to prevent the jumping animation from playing but it seems like this hook is just never called. I've left it empty and put prints in there and not even the prints seem to run. How could I stop the jumping animations from playing?

That's the base gamemode, did you check the files from the gamemode you're currently using to see if it ever calls that hook?

Technically yes, it should but apparently, from a [url=https://github.com/garrynewman/garrysmod/search?utf8=%E2%9C%93&q=HandlePlayerJumping&type=Code]quick search[/url] it doesn't calls the hook anywhere.

[Sir. Pumpin']

 local ourMat = Material( "materials/hudmodels/lightsaber.vtf" )


    surface.SetDrawColor( 255, 255, 255, 255 )
    surface.SetMaterial( ourMat )    
    surface.DrawTexturedRect( ScrW() / 100, ScrH () / 1.3, 70, 40 )

Just incase you need the code :p

Anyways, the problem is that the material shows as purple and black, the lightsaber.vtf IS in \Steam\steamapps\common\GarrysMod\garrysmod\materials\hudmodels.vtf

But it doesn't do it :/, could it be because the code is in darkrp modification? please help!

Another problem with this script...

local chatcommands = {};

hook.Add("PlayerSay", "Commands Base", function(ply, text, teamc, alive)
	local chat_string = string.Explode(" ", text);
	
	for k, v in pairs( chatcommands ) do
		if( chat_string[1] == k ) then
			table.remove(chat_string, 1);
			v(ply, chat_string);
			
			return "";
		end
		
		if( string.find(k, chat_string[1]) != nil ) then
			local start, endp, word = string.find(k, chat_string[1]);
			
			if( endp - (start - 1) > 2 ) then
				ply:ChatPrint("Invalid command! Did you mean '"..tostring( k ).."'?");
				
				return "";
			end
		end
	end
	
	return text;
end )

function RegisterChatCommand(strCommand, Func)
	if( !strCommand || !Func ) then return; end
	
	for k, v in pairs( chatcommands ) do
		if( strCommand == k ) then
			return;
		end
	end
	
	chatcommands[ tostring( strCommand ) ] = Func;
end

-- Chat commands

-- Test command
RegisterChatCommand("!fuckyou", function(ply, args)
	if( ply:IsSuperAdmin() ) then
		local pname = args[1];

		for _, v in pairs( player.GetAll() ) do
			if( string.find(v:Nick(), pname) ) then
				v:ChatPrint("Hey man, fuck you.");
			end
		end
	end
end)

-- Screengrab
RegisterChatCommand("!screengrab", function(ply, args)
	if ply:IsAdmin() then
		ply:ConCommand("screengrab")
	end
end)

It breaks my Spectator Deathmatch for my TTT server. I don't know why or how, but it does.

Returning a non-nil value from a hook will prevent other hooked functions from being called.

Remove

return text;

and only return from hooks when you have to

[MaxShadow]

I'm working on my first STOOL. I've been looking inside some example tools, and I noticed that all of them work serverside. Even for simple functions like measuring the distance between two points, all of them have this line inside LeftClick or RightClick:

if(CLIENT) then return true end

Also, I noticed that if the tool has to do something on the client, some people send a message from the server to the client, and then it sends the results back to the server. Is there any reason why I shouldn't do clientside stuff directly inside the LeftClick and RightClick hooks?

That happens when you're not subscribed to those mods. Perhaps they were removed from the workshop (with those names, it's quite probable)

Edit: I just noticed you said that those mods are yours. Did you upload them to the workshop? As far as I know, GMOD won't load unsuscribed gmas unless its in offline mode.

[MaxShadow]

[QUOTE=Ehmmett;49681556]Well yeah I'm not subscribed to it, I've only just made the gma. It's not ready to go on the workshop yet.

So I have to publish it to mount it? I don't remember it always being like that.[/QUOTE]

Yeah you have to, or go into offline mode, unless there's a command to force load gmas. If you just want to test them, put the contents in a subfolder inside "addons", you don't need a gma.

Put the .gmas inside an addon folder or outside of the addon folder.
