I think you misunderstood my question. I can input the special characters just fine, but in the code itself, any special characters are interpreted as �s. I want an é to be kept in my variable as é, not �

That's probably because you want to use multibyte characters as single byte, and that's where you fail.

Willox made a utf8 library for Lua, but I am not sure if he released it or not, you should ask him.

According to ARitz Cracker you have to make sure this is checked in your Lua files. That made it so my gPhone could have a Russian translation

This is required if you use non ascii characters in the file itself, I am not sure if it affects anything when the characters are never in that file.

Having a problem when trying to convert the Combine Control swep base over to Nutscript 1.1.

I have tried and tried to get this to work, but no luck.

This is the line the error points me too. I am not that experienced in coding, so all of this is complicated to me, but any help is appreciated! There is various other errors, but I'll try and solve them one at a time.

self.currentFreeAimOffset is nil.

Do you define it somewhere other then that line?

I can't get Entity:SetParentPhysNum to work and the wiki is wrong on the usage of it. Can anyone help? I'm just trying to parent a prop to a ragdoll bone.
Same for Entity:SetParent(Entity,Index). This doesn't work either. Should I open an issue on garrysmod-issues?

I am simply saving a translated string as a variable (often containing accents or other special characters i.e. Cyrillic or Chinese) and the special characters are not being retained. I dont't recall having used anything related to single or multi byte allocation. Would willox's library help in this instance?

[hio77]

Looking to implement a way to keep players out of no draw areas on maps to disallow players from getting there.

Trying to find a good balance between adding to server load and implementing an effective solution.

So far, we have looked at doing Killzones (preferably with a warning system) using the likes of using FindInBox but Ild expect constantly checking this would be pretty heavy processing wise.

Also looked at adding invisible walls, and using the PhysicsCollide To notify the player they have hit the wall, Making use of the Entity Callback.

Mainly looking for comments of performance or if there is a better way to achieve this.

[FuzionUK]

I uploaded my SWEP to the workshop and the sounds are working (for me at least), a friend downloaded it to test it and this showed up

Failed to load sound "sound\weapons\allu\allu_redbull.mp3", file probably missing from disk/repository
Create Stream Failed error 41

I put the mp3's in a sound file located AlluAWP/sound/weapons/allu.
Any reason why it isn't working for people who download it?

[B]Edit:[/B]
Problem solved, had to remove sound/ for it to work.

[Exho]

Is it possible to use SetMaterial("wood/infceilinga") on a clientside model? Using the material option in the SWEP construction kit does nothing and I can't get the material to change manually.

[G4MB!T]

You could set a variable on the entity then override RenderOverride and render the material.

[tzahush]

hey guys, i ran into a problem.
So i got a database where i store an Angle, that angle is being seperated with a "," in the database so it'll be easy for me to take it out, and use string.Explode to take the x,y,z apart.
for some reason when i try to make the x,y,z an angle it prints out as 0,0,0.
This is my code:

	for k,v in pairs(info) do
		local tempang = string.Explode(",",v["angpos"])
		print(tempang[1])
		print(tempang[2])
		print(tempang[3])
		print(Angle(tempang[1],tempang[2],tempang[3]))
end

The output is this:

-0.03125
-171.9375
0
0.000 0.000 0.000

anyone has any idea why?

[G4MB!T]

Which part is right and which part is wrong?

[tzahush]

[QUOTE=G4MB!T;47463716]Which part is right and which part is wrong?[/QUOTE]

the first 3, are the x,y,z, and for some reason, when i combine them to an actuall Angle they come out as 0,0,0.

[Fantym420]

they are strings, try converting them to numbers

		print(Angle(tonumber(tempang[1]),tonumber(tempang[2]),tonumber(tempang[3])))

Hello there,

I am trying to learn Lua scripting and decided to try to update a gamemode for gmod13.
But I've run into an error I just can't figure out. I keep getting this error:

This hides them.

[serfma]

This is kinda a silly question but is it possible, at all, for a player model to kill and spawn players in locations they shouldn't normally spawn in? I have a model in my TTT server and players with them are instantly dying once they spawn in, but not all of the time. I'm not really sure how to debug this and I didn't think it was remotely possible for a model to cause that, but I've witnessed it. Might also add that while using the TTT Damage logs addon by tommy, they're apparently dying by unknown/world. :P

[Maurdekye]

I'm having problems with precached sounds in a SWEP. I have this code here;

[lua]
local shootSound = Sound( "Weapon_Crossbow.Single" )

function SWEP:PrimaryAttack()

self.EmitSound( shootSound )
end
end
[/lua]

But whenever I fire the weapon, it gives an error saying it tried to use a null entity. Why is that?

[editline]6th April 2015[/editline]

Nevermind, I just had to do self.Owner:EmitSound().

[PortalGod]

even though you fixed it, the problem was because you used a dot instead of a colon
a colon automatically passes the object you're calling the function on as the first argument to the function
