How to make a gun bullet ignore parts? Like walls and objects.

Hey guys I have a problem. I have a script that shoots players that aren't me and It works perfectly. But the problem is that the bullet shoots through walls and objects. Any idea why and how to make it not do it?

Here's the script:

01local Rel = 0
02local MaxDis = 100
03local Mode = "Normal"
04 
05local Lazor = Instance.new("Part")
06Lazor.BrickColor = BrickColor.new("really red")
07Lazor.Anchored = true
08Lazor.BottomSurface = "Smooth"
09Lazor.TopSurface = "Smooth"
10Lazor.CanCollide = false
11Lazor.Transparency = 0.3
12Lazor.Reflectance = 0.2
13local Mesh = Instance.new("CylinderMesh")
14Mesh.Scale = Vector3.new(0.2,1,0.2)
15Mesh.Parent = Lazor
16Mesh.Offset = Vector3.new(-0.2,0,0)

18function CheckHuman(Humanoid, Player)
19   if Humanoid.Health == 0 then return false end
20    if Player.Name == "wilsonsilva007" then return false end -- We're not gunna shoot at our owner!
21   return true
22end
23 
24function GetDistance(Player, C_Pos)
25   local Character = Player.Character
26   if Character~=nil and Mode == "Normal" then
27      local Head = Character:findFirstChild("Head")
28      local Human = Character:findFirstChild("Humanoid")
29      if Head~= nil and Human~= nil then
30         if CheckHuman(Human, Player) then
31            local Distance_1 = Head.Position-C_Pos
32            local Distance = Distance_1.magnitude
33            return Distance, Head
34         end
35      end

37   return MaxDis*5, nil

42   local nearest = nil
43   local nearestdis = MaxDis*5
44   local NearestHead = nil
45   local P = game.Players:GetChildren()
46   for i = 1, #P do
47      local Dis, His_Head = GetDistance(P[i], Pos)
48      if Dis<= MaxDis*5 and Dis<nearestdis then
49         nearest = P
50         nearestdis = Dis
51         NearestHead=His_Head

61   script.Parent.Parent.Main.CFrame = script.Parent.Parent.Main.CFrame * CFrame.Angles(math.pi/2,0,0)
62   script.Parent.Parent.Shotpart.CFrame = script.Parent.CFrame + script.Parent.CFrame.lookVector*1.6
63   script.Parent.Parent.Shotpart.CFrame = script.Parent.Parent.Shotpart.CFrame * CFrame.Angles(math.pi/2,0,0)
64   script.Parent.Parent.Scanner.CFrame = script.Parent.CFrame + script.Parent.CFrame.lookVector*1.6
65   script.Parent.Parent.Scanner.CFrame = script.Parent.Parent.Scanner.CFrame * CFrame.Angles(-math.pi/2,0,0)

Try setting the CanCollide property of Lazor to true. RayCurse 1518 — 7y

Laser.CFrame = script.Parent.CFrame + script.Parent.CFrame.lookVector * Distance/2 You do not check for any parts that are in the way. User#5423 17 — 7y
