Making a part that goes from one point to another

[Edryi007]

Hello there, developers of Roblox! Recently, I have made a Police officer AI that can shoot you if you are wanted. Sadly, the officer just shoots through walls, and I need to check if there are any obstacles in the GUN to CHARACTER direct path. I need to generate a part from two Vector3 positions. First would be the barrel of the gun, and second being the characters HumanoidRootPart. I have no idea on how to make this, so I need some help. Thanks in advance, Edryi007.

this is an example of how to do it

local gun = script.Parent
local bulletSpeed = 100
local bulletRange = 200
local bulletDamage = 10


local muzzle = gun.Handle.Muzzle


local function fireGun()
  
    local bulletDirection = muzzle.CFrame.LookVector
    
   
    local raycastResult = workspace:Raycast(muzzle.Position, bulletDirection * bulletRange)
    
   
    if raycastResult then
        -- Get the part that was hit
        local hitPart = raycastResult.Part
        
      
        if hitPart and hitPart.Parent:FindFirstChild("Humanoid") then
            hitPart.Parent.Humanoid:TakeDamage(bulletDamage)
        end
    end
    
  
    local bullet = Instance.new("Part")
    bullet.Shape = Enum.PartType.Ball
    bullet.Size = Vector3.new(0.5, 0.5, 0.5)
    bullet.Position = muzzle.Position
    bullet.Velocity = bulletDirection * bulletSpeed
    bullet.CanCollide = false
    bullet.Parent = workspace
    
    
    game:GetService("Debris"):AddItem(bullet, bulletRange / bulletSpeed)
end


gun.MouseButton1Click:Connect(fireGun)
