Ugh, tried going back into Lua on a very old and simple project, but whenever the flechettes attach to an NPC, the explosion effects simply seem to go to the origin of the map rather than explode where the NPC is. How would I go about making it so that no effects appear if a flechette hits an NPC (becomes non-existant)?

I tried something like this at around line 110 and commenting out the code pertaining to the timed effects:
[lua]timer.Simple(2.7,function()
if IsValid(ent) then
ParticleEffectAttach("aurora_02b",PATTACH_ABSORIGIN_FOLLOW,ent,0)
ParticleEffectAttach("electrical_arc_01_system",PATTACH_ABSORIGIN_FOLLOW,ent,0)
ParticleEffectAttach("Weapon_Combine_Ion_Cannon_Explosion",PATTACH_ABSORIGIN_FOLLOW,ent,0)
ParticleEffectAttach("cingularity",PATTACH_ABSORIGIN_FOLLOW,ent,0)

end
end)[/lua]

But all that does is completely remove the extra delayed effects attached to the flechette, although there are no effects attached to the origin of the map.

Suggestions?

Gah, nevermind, I realized the thing I did at the bottom wasn't in the primary fire function... I'm dumb.

[Netheous]

[lua]function DB_GlobalSave()
for _, ply in pairs (player.GetAll()) do
if ply:IsValid() then
SQLaction = sql.Query("UPDATE ply_info SET money = "..ply.stats.money..", items = 'smallbattery', WHERE u_id = '"..ply:SteamID().."'")
end
if !SQLaction then
print(sql.LastError(SQLaction))
end
end
end[/lua]

Timer Error: [gamemodes\nethsrp\gamemode\database.lua:54] attempt to concatenate field 'money' (a nil value)

If anyone is curious, this is where I setup those tables:
[lua]function DB_LoadPlayer( person )
if !person:IsValid() then return end
SQLaction = sql.Query("SELECT u_id, money, items FROM ply_info WHERE u_id = '"..person:SteamID().."'")
if SQLaction then

person.stats =
{
money = SQLaction.money,
xp = 1337,
points = 1339
}

person.items =
{
SQLaction.items
}
DB_SendStats( person )
//DB_SendItems( person )
else
DB_NewPlayer( person )
end
end
hook.Add( "PlayerInitialSpawn", "DB_LoadPlayer", DB_LoadPlayer )[/lua]

What difference between function and local function?
You can't call local function globally?

[rsk_]

[QUOTE=aurum481;34540350]What difference between function and local function?

a local function can only be run within the block of code its been made in.

[ralle105]

Acts like any other local, it doesn't exist outside it's scope.

[QUOTE=Drakehawke;34533346]GM:HUDPaint is for gamemodes, which is loaded after autorun hence it's nil when your file is ran.

Use this instead:

end )[/lua][/QUOTE]
Thank you very much, it works. Just one question: What units is the result for GetVelocity() in? When I walk its 250, when I run its 500 (gmod walk and run are faster than normal), when I drive a vehicle its 800-1100. Id like to convert them to kph.
Since wiki is not working properly I get no uselful results for this function.

Edit: I have measured this:
vehicle
normal mode: measured max: 1580 specified max: 90 mph 144.84096 kph
boost mode: measured max: 2110 specified max: 120 mph 193.12128 kph

Units per a minute at a guess.

[url]https://developer.valvesoftware.com/wiki/Dimensions[/url]

It's in units per second.
Feet per second = speed/16
Miles per hour = (speed * 3600)/5280
Kilometers per hour = (speed * 0.3048 * 3600)/(1000 * 16)

[Flubadoo]

Is there a tutorial somewhere that teaches you how to make your own particle system/particle effects that can be used in conjunction with util.Effect() or ParticleEffectAttach()?

EP2 ones are nice but I'd rather make my own.

Getting a weird problem on my server.

Basically on TTT, every so often, when someone drops any weapon on the floor then tries to pick it up with their magneto stick, the weapon gets stuck inside the floor, spazzes out (With dust clouds) and the server crashes. This never used to happen on our old host, but I have no idea why a different host would affect this.

The dumps confirmed it was a vphysics crash, but I'm not really sure what could be done to fix it aside from not letting people pick them up.

im gonna post in this thread again. hope its fine.
ive been trying all day to make a AmmoCrate. entity for rp that when you click use on it you would obtain 20 Pistol ammo ive been trying for 6hrs today without luck i hope theres some help out there

How do you add 1 to network bool?

e.g

[lua]self.Entity:SetNWBool("fertlimit", +1)[/lua]

It was set at 0 on initialize.

you cat 'add' to a bool, bools are 'true' or 'false'

[Mrkrabz]

[QUOTE=Deadman123;34552007]you cat 'add' to a bool, bools are 'true' or 'false'[/QUOTE]

Yes, but bools can also be 1,2,3 etc?

[Deadman123]

no

[editline]ajb[/editline]

A 'Boolean' is true or false, not numbers, use NWInts instead, or something more efficient

[AngryChairR]

[QUOTE=Mrkrabz;34552061]Yes, but bools can also be 1,2,3 etc?[/QUOTE]

true false 1 0

[Mrkrabz]

[QUOTE=AngryChairR;34552195]true false 1 0[/QUOTE]

Balls to it, Ill just use the old friend variable.

Don't know why you're trying to add one, it can only be 0 or 1 so just set it to 1

[Mrkrabz]

[QUOTE=AngryChairR;34552219]Don't know why you're trying to add one, it can only be 0 or 1 so just set it to 1[/QUOTE]

I was using it for when to remove something, or when it = 5. But now coming to think about it a variable will be much easier.

[ArmageddonScr]

If you don't need the clients knowing the variable you shouldn't be using the SetNW functions, at all.

You will need to define ply in init.lua, for example local ply = self.Entity.dt.owning_ent (This is for my entity) Then do

[lua]ply:PrintMessage( HUD_PRINTCENTER, "Out of bounds!")[/lua]

Where are you calling that in init.lua?
