I’m currently working on a script for a laser beam that should stay on the target when the mouse is held over it. However, I’ve encountered an issue where, intermittently, the beam seems to behave unexpectedly, as illustrated in the attached GIF.
I suspect there might be an occasional problem with the raycasting calculations or other aspects of the script. Most of the time, it works correctly, but I’m keen to ensure a consistently smooth experience for users.
Anyway, whoever is reading this thank you in advance for your time and expertise!

I see that you’re facing an issue with maintaining synchronization while retaining rapid firing for your laser beam script in Roblox. You’re definitely on the right track with your concerns, and I’d be happy to help.
Client-side Synchronization:
The problem you’re encountering may be due to slight differences in cursor positions between the client and server. To improve synchronization, you can make a small change to your client script. Instead of firing the remote event when the tool is activated, you can continuously update the remote event with the mouse’s current position while the tool is activated. Here’s a modified client script:
-- Services
local runService = game:GetService("RunService")
local players = game:GetService("Players")
-- Player-related
local player = players.LocalPlayer
local mouse = player:GetMouse()
-- Tool-related
local tool = script.Parent
-- Folders
local remoteEventsFolder = tool:WaitForChild("RemoteEventsFolder")
local remoteEvent = remoteEventsFolder:WaitForChild("RemoteEvent")
-- Configuration
local gunConfig = tool:WaitForChild("Configuration")
local currentAmountOfAmmo = gunConfig:WaitForChild("CurrentAmountOfAmmo")
-- Flag to track the activation state
local activated = false
local heartbeat -- Variable to store the heartbeat connection
-- Function to update the remote event with mouse position
function UpdateRemote()
if activated then
remoteEvent:FireServer(mouse.Hit.Position)
end
}
-- Modify the Activated event to continuously update the remote event
tool.Activated:Connect(function()
activated = true
-- Check if the gun is automatic
if gunConfig:WaitForChild("IsAutomatic").Value == true then
-- Connect to the Heartbeat event for automatic firing
heartbeat = runService.Heartbeat:Connect(UpdateRemote)
else
UpdateRemote()
end
})
-- Modify the Deactivated event to disconnect the heartbeat
tool.Deactivated:Connect(function()
activated = false
if heartbeat then
heartbeat:Disconnect()
end
})
These modifications will continuously update the remote event with the mouse’s position while the tool is activated, allowing for rapid firing while maintaining synchronization.
Server-side Logic:
On the server side, it’s important to ensure that the OnCooldown variable is correctly managed. You can set it to true when the gun fires and reset it after the cooldown period to prevent rapid, unintended firing.
Additionally, if the issue persists, consider adding more debugging information to your code to pinpoint the exact cause of the problem, such as printing the mouse position you receive from the client.
I hope these suggestions help you resolve the synchronization issue while retaining rapid firing. If you encounter any issues during testing or If you have any more questions or need further assistance, feel free to ask. We’re here to help!
Works like a charm after upgrading the server and client script to your suggestion.
I did notice your usage of ChatGPT, however I am still happy with the results. So thank you!
