Help needed - Dropping the current weapon on death.

[QBiT]

Hello, im _really_ new to lua and ive been coding a basic gamemode, now im experiencing a problem when i try to do this (init.lua):

function GM:PlayerDeath( ply )
		ply:DropWeapon(ply:GetActiveWeapon()) 
end

It just prints out this error:

ERROR: GAMEMODE:'PlayerDeath' Failed: ***/gamemode/init.lua:28: Tried to use a NULL entity!

Line 28:

ply:DropWeapon(ply:GetActiveWeapon()) 

[b]PS: Can anyone explain hooks to me? Also, how do i set a hotkey for a derma menu, like F1, F2 ect?[/b]

E: Im trying to make the player to drop the current weapon on spawn.

function WeaponDropOnDeath(ply)

    if (ply:GetActiveWeapon():IsValid()) then
        ply:DropWeapon( ply:GetActiveWeapon())
    end

end
hook.Add("DoPlayerDeath", "WeaponDropOnDeath", WeaponDropOnDeath) 

This works for me. :)

hooks are like events that trigger a certain function.
