Raycasting guns always have weird bullet positions

Ok so, I have been trying to make raycast guns recently, but every time I make them, the bullets are weirdly positioned. I tried so many videos to learn to make a raycast gun, but they all have the same bullet position.

here is what I want it to be like [This example is from the FE gun kit made by Thienbao2109]

And this is what it looks like when I make the gun

How do developers archive this? I would really appreciate it if someone explains how to do this or give some information on how I could do this.

You didn’t provide any code, so I’ll have to keep it general.

When defining the unit direction of a ray to go towards you can do this by subtracting two vectors from one another or by using the .LookVector of a CFrame (which returns a 3d vector) then multiply this vector by the distance (number value) you’d like to cast a ray for which is either a constant or the exact distance between A to B.

Example:

function CastRay(Origin, Point)
    ---- Two different direction methods
    -- Vector - Vector .unit
    local Direction = (Point - Origin).unit
    
    -- Camera CFrame's LookVector
    local Direction = Camera.CFrame.LookVector
    
    ---- Two different distance methods
    -- exact distance between A to B
    local Distance = (Point - Origin).magnitude
    
    -- constant
    local Distance = 100 -- studs
    
    -- defining the ray
    local ray = Ray.new(Origin, Direction * Distance)
    
    -- casting and returning the ray results
    local IgnoreList = {Character} -- Add whatever you'd like
    return rayHitPart, rayHitPosition, rayHitNormal, rayHitMaterial = workspace:FindPartOnRayWithIgnoreList(ray, IgnoreList)
end

This is my code

 local RayCast = Ray.new(FromP,(ToP-FromP).unit*100)
 local Part,Position,Normal = game.Workspace:FindPartOnRay(RayCast,Player.Character, false,true)
 local Dist = (ToP-FromP).magnitude
 if not Dist then Dist = 300 end
 local Lazer = Instance.new("Part")
 Lazer.Parent = game.Workspace
 Lazer.BrickColor = BrickColor.new("Electric blue")
 Lazer.Anchored = true
 Lazer.CanCollide = false
 Lazer.Size = Vector3.new(0.1,0.1,Dist)
 Lazer.CFrame = CFrame.new(FromP,Position)*CFrame.new(0,0,-Dist/2)
 game.Debris:AddItem(Lazer,0.2)
 if Part and Part.Parent:FindFirstChild("Humanoid") then
  Part.Parent.Humanoid:TakeDamage(30)
 end
end)```

What did you define as ToP and FromP?

I made a mistake while sending the code

game.ReplicatedStorage.RayCastEvent.OnServerEvent:Connect(function(Player, FromP, ToP)
 local RayCast = Ray.new(FromP,(ToP-FromP).unit*100)
 local Part,Position,Normal = game.Workspace:FindPartOnRay(RayCast,Player.Character, false,true)
 local Dist = (ToP-FromP).magnitude
 if not Dist then Dist = 300 end
 local Lazer = Instance.new("Part")
 Lazer.Parent = game.Workspace
 Lazer.BrickColor = BrickColor.new("Electric blue")
 Lazer.Anchored = true
 Lazer.CanCollide = false
 Lazer.Size = Vector3.new(0.1,0.1,Dist)
 Lazer.CFrame = CFrame.new(FromP,Position)*CFrame.new(0,0,-Dist/2)
 game.Debris:AddItem(Lazer,0.2)
 if Part and Part.Parent:FindFirstChild("Humanoid") then
  Part.Parent.Humanoid:TakeDamage(30)
 end
end)

Nevermind. I figured out how. What I did is added Trail effects to the bullets .
