I am trying to make a gun that damages NPC like zombies but not other players, Help?

I have tried this script but it damages other players fight like the NPC as well..... My script (see if you can add anything to make it not damage other player and I can't use teams as I am doing like a "zombie rush" game so no teams): local serverStorage = game:GetService(“ServerStorage”) local replicatedStorage = game:GetService(“ReplicatedStorage”) local KOValue = “Kills” local WOValue = “Wipeouts” local damage = 30 replicatedStorage.ShootEvent.OnServerEvent:Connect(function(player,tool,position,part) if game.Workspace[player.Name].Humanoid.Health <= 0 then — The player is dead, do not do anything else local distance = (tool.Handle.CFrame.p – position).magnitude if game.Workspace:FindFirstChild(player.Name..“‘s Trajectory”) then game.Workspace:FindFirstChild(player.Name..“‘s Trajectory”):Destroy() end local trajectory = Instance.new(“Part”,game.Workspace) local smoke = serverStorage.SmokeParticle:Clone() smoke.Parent = tool.Handle trajectory.BrickColor = BrickColor.new(“Institutional white”) trajectory.Material = “SmoothPlastic” trajectory.Name = player.Name..“‘s Trajectory” trajectory.Transparency = 0.5 trajectory.Anchored = true trajectory.Locked = true trajectory.CanCollide = false trajectory.Size = Vector3.new(0.3,0.3,distance) for i = 0,distance,6 do trajectory.CFrame = CFrame.new(tool.Handle.CFrame.p,position) * CFrame.new(0,0,-distance / 2) wait(0.0001) end smoke:Destroy() if part then if part.Name == “Head” or part:IsA(“Hat”) and part.Parent:FindFirstChild(“Humanoid”).Health > 0 then — Boom headshot replicatedStorage.Headshot:FireClient(player) damage = 50 end local humanoid = part.Parent:FindFirstChild(“Humanoid”) if not humanoid then humanoid = part.Parent.Parent:FindFirstChild(“Humanoid”) else humanoid:TakeDamage(damage) if humanoid.Health <= 0 then player.leaderstats[KOValue].Value = player.leaderstats[KOValue].Value + 1 game.Players[humanoid.Parent.Name].leaderstats[WOValue].Value = game.Players[humanoid.Parent.Name].leaderstats[WOValue].Value + 1 end end wait(0.25) if trajectory then trajectory:Destroy() end end end end)

replicatedStorage.EquipAnimation.OnServerEvent:Connect(function(player,animation) local newAnim = game.Workspace[player.Name].Humanoid:LoadAnimation(animation) newAnim:Play() replicatedStorage.UnequipAnimation.OnServerEvent:Connect(function(player,animation) newAnim:Stop() for i,v in pairs(game.Workspace:GetChildren()) do if v.Name == player.Name..“‘s Trajectory” then v:Destroy() end end end) replicatedStorage.Reload.OnServerEvent:Connect(function(player,animation) newAnim:Stop() local reloadAnim = game.Workspace[player.Name].Humanoid:LoadAnimation(animation) reloadAnim:Play() end) end)
