I'm making a gun that tells me the Instance of the thing hit, but it seems like it only works sometimes ? idk if it's because of the way I've attached the attachment "rayorigin" or something else, ill attach the scripts and some pictures bellow. any help would be great.

#

local gun = script.Parent.Parent
local GetMousePosition = game.ReplicatedStorage.GetMousePosition

gun.Activated:Connect(function()
    local player = game.Players:FindFirstChild(gun.Parent.Name)
    local RayOrigin = gun.Handle.RayOrigin.Position
    
    local MousePosition = GetMousePosition:InvokeClient(player)
    
    local DirectionToFire = (MousePosition - RayOrigin).Unit * 500
    
    local raycastResult = workspace:Raycast(RayOrigin, DirectionToFire)
    
    if raycastResult then
        print(raycastResult.Instance)
    end
end)

#

local ReplicatedStorage = game:GetService("ReplicatedStorage")
local getMouseRemote = ReplicatedStorage.GetMousePosition

ReplicatedStorage.GetMousePosition.OnClientInvoke = function()
    return game.Players.LocalPlayer:GetMouse().Hit.Position
end

#

the first one is for the gun and the second is a local script that get the mouse position

My issue is that I think the raycastorigin is still on the ground and not sticking to the gun

#

even tho it is parent to the handle

I think you can add more accuracy for your ray

shy lion May 31, 2025, 11:13 AM

#

sullen mortar I think you can add more accuracy for your ray

sorry for taking ages to reply have been bussy

#

like the multiplying thing ?

sullen mortar May 31, 2025, 11:14 AM

#

The direction to fire

#

Maybe if you add a lil bit of accuracy it might work better

#

I have a gun script I’ll give you a line or two later

#

okay, thanks a lot

#

Yo! Idk if it more accurate but i think a client replication would be better

#

Whats the main issue tho? The bullet is going to the wrong direction?

#

Oh forget about it

shy lion May 31, 2025, 3:24 PM

#

Maybe, but also what about the way the attachment is on tha handle, i added it in the workspace, but when i click it in the game it shows it as the place in the workspace, not the tip of the gun, i think thats the issue

#

I read everything now

shy lion May 31, 2025, 3:25 PM

floral zodiac May 31, 2025, 3:25 PM

It’s because you are the Position property of the attachment instead of the WorldPosition property

#

Sorry for the double ping, wasn’t very smart of me

wait what

#

I've never used that

like

#

i put the tool in the workspace, I added a Ray origin to the handle and then moved it to the Starter pack

floral zodiac May 31, 2025, 5:40 PM

There’s difference between Attachement.Position and Attachement.WorldCFrame.Position

shy lion May 31, 2025, 6:18 PM

#

OHHHH

floral zodiac May 31, 2025, 6:33 PM

#

It worked?

sullen mortar May 31, 2025, 7:09 PM

#

Yo

#

Im gonna give u the line

#

I made the system a few months ago

#

The Tool.Activated Event is in the client side script

#

local function onActivated()
  local ray = Camera:ScreenPointToRay(Camera.ViewportSize.X/2, Camera.ViewportSize.Y/2 - GuiService:GetGuiInset().Y)
    if ray then
     local InvokeSuccess, errormessage = pcall(function() SendRayToServer:InvokeServer(ray) end)
      if not InvokeSuccess then warn("Invoke error: "..errormessage) end
     end
end

#

Might give a more accuracy
