Prop Hunt Player Class Error

[Belly136]

Well this happends randomly i don't know what is causing it...

[ERROR] gamemodes/prop_hunt/gamemode/player_class/class_hunter.lua:51: Tried to use a NULL entity!
1. UnLock - [C]:-1
2. unknown - gamemodes/prop_hunt/gamemode/player_class/class_hunter.lua:51

Timer Failed! [Simple][@gamemodes/prop_hunt/gamemode/player_class/class_hunter.lua (line 60)]

class_hunter.lua:

// Create new class
local CLASS = {}


// Some settings for the class
CLASS.DisplayName			= "Hunter"
CLASS.WalkSpeed 			= 230
CLASS.CrouchedWalkSpeed 	= 0.2

CLASS.DuckSpeed				= 0.2
CLASS.DrawTeamRing			= false

	local cl_defaultweapon = pl:GetInfo("cl_defaultweapon")

 		pl:SelectWeapon(cl_defaultweapon)
 	end 
end

		pl:Blind(false)
	end
	local lockfunc = function()
		//MyLockFunc(pl.Lock())
		pl.Lock(pl)
	end
	local unlockfunc = function()
		//MyUnlockFunc(pl.UnLock())
		pl.UnLock(pl)
	end
	
	if unlock_time > 2 then
		pl:Blind(true)
		
		timer.Simple(unlock_time, unblindfunc)
		
		timer.Simple(2, lockfunc)
		timer.Simple(unlock_time, unlockfunc)
	end
end


// Called when a player dies with this class
function CLASS:OnDeath(pl, attacker, dmginfo)
	pl:CreateRagdoll()
	pl:UnLock()
end


// Register
player_class.Register("Hunter", CLASS)

Is there any way to fix that?

[Blasteh]

It happens when the timer runs and the player has already disconnected.

Add a check to see if the player still exists before running the unlock.

[Belly136]

Well i'm a noob in this, can anyone help?

Edit:
It doesn't matter, server had 18 players when that error came again.

[Belly136]

Ugh

Can anyone explain?

I started with lua like 2 weeks ago and that wouldn't help much.

People here are like elitists of coding, they will tease you with vague answers but never really give a solution that the common person gets.

I'm on mobile so I dont know the line numbers to help much. But google "gmod timer.simple" and "gmod IsValid". Have it check if the player is valid before running anything else

[Acecool]

They're right. If you start a timer, you need to verify the data when it runs. There are also some cases where a function may run and take a long time to the point where further down the content is no longer valid ( one of the reasons why I suggest helper-functions, aside from reducing repeating code ).

Add:

if ( !IsValid( _variable ) ) then return; end

in the timer; change _variable to the variable you're using..

[Belly136]

Like this?

if ( !pl:IsValid( timer.Simple ) ) then return; end

[Nookyava]

Check if the player is valid, not the timer.
