I am trying to learn Lua and I decided that for my first project I would try to fix a broken script. I have fixed a few of the bugs but I'm stuck now. Can you help me?

    function SWEP:PrimaryAttack()
     if( CurTime() < self.NextStrike ) then return; end
     self.Weapon:EmitSound("player/skick/sparta.mp3")
     self.NextStrike = ( CurTime() + 3.5 );
     timer.Simple( 1.80, function() self:AttackAnim() end)
                        -Next line broken-
         timer.Simple( 2.40, function() self.Weapon:SendWeaponAnim( ACT_VM_IDLE ) end);
     timer.Simple( 2.00, function() self.ShootBullets( self ) end)
     self.Owner:SetAnimation( PLAYER_ATTACK1 );
end 

function SWEP:ShootBullets()
    -Next line Broken-
         local trace =Owner:GetEyeTrace();
    if trace.HitPos:Distance(self.Owner:GetShootPos()) <= 130 then
        if( trace.Entity:IsPlayer() or trace.Entity:IsNPC() or trace.Entity:GetClass()=="prop_ragdoll" ) then
                timer.Simple(0, game.ConsoleCommand, "host_timescale 0.1\n")
                timer.Simple(0.5, game.ConsoleCommand, "host_timescale 1\n")
            self.Owner:EmitSound( self.FleshHit[math.random(1,#self.FleshHit)] );
        else
            self.Owner:EmitSound( self.Hit[math.random(1,#self.Hit)] );
        end
                bullet = {}
                bullet.Num    = 5
                bullet.Src    = self.Owner:GetShootPos()
                bullet.Dir    = self.Owner:GetAimVector()
                bullet.Spread = Vector(0.04, 0.04, 0.04)
                bullet.Tracer = 0
                bullet.Force  = 250
                bullet.Damage = 1000000
            self.Owner:FireBullets(bullet)
    end

I'm getting an error saying Attempting to index field 'Weapon' (a nil value). Can anyone explain how to fix this?

Im not allowed to post imagesthis is what im getting Error image

您收到该错误的原因是“武器”（特别是 self.Weapon）未初始化。self.Weapon 没有指向任何东西，所以你不能在它上面调用任何函数。

你能告诉我们错误消息引用的行吗？看起来文件是shared.lua第 84、85 和 90 行。周围的代码也会很有帮助。我猜您将其作为原始问题的一部分发布，但是没有任何行号就没有帮助！
