FireServer
Fires a RemoteEvent or UnreliableRemoteEvent through Roblox's own serializer.
Syntax
:FireServer(...) -> ()Parameters
The method is variadic. Every argument is serialized by the engine's own FireServer implementation. Supported argument types:
| Type | Description |
|---|---|
boolean | Sent as a variant boolean. |
number | Sent as a variant double. |
string | Sent as a variant string. Limited to 2048 bytes. |
Instance | Sent as a variant instance reference. |
Vector3 | Sent as a variant Vector3. |
Unsupported argument types raise a Lua error.
Returns
No return value.
Description
FireServer is available on RemoteEvent and UnreliableRemoteEvent instances. It resolves the instance's live bound FireServer method and invokes it on the game thread, building the argument tuple through the engine's variant serializer.
The call is synchronous. If the method is unavailable or an argument cannot be serialized, the script raises an error that appears in the executor output.
Example
local remote = game:GetService("ReplicatedStorage"):WaitForChild("RemoteEvent")
-- Supported: boolean, number, string, Instance, Vector3
remote:FireServer("Hello", 123, true, Vector3.new(0, 10, 0), workspace)Notes
