Coming from RageMP

If you've been developing on RageMP, the transition to HELIX is straightforward. Both platforms focus on multiplayer game servers, but HELIX runs on Unreal Engine 5 instead of GTA V's RAGE engine, giving you far more creative freedom.

Key Differences

	RageMP	HELIX
Engine	Modified RAGE (GTA V)	Unreal Engine 5
Scripting	JavaScript, C#	Lua, Blueprint, JavaScript
World Building	GTA V map + MLOs	Full UE5 editor (HELIX Studio)
Hosting	Self-hosted only	Instant Hosting or self-hosted
Client Mods	Limited to GTA V assets	Custom assets, Nanite meshes, full UE5 pipeline

API Comparison

RageMP	HELIX	Notes
mp.events.add('event', cb)	RegisterServerEvent('event', cb)	Server event subscription
mp.events.callRemote('event', data)	TriggerServerEvent('event', data)	Client-to-server
player.position = new mp.Vector3(x,y,z)	character:SetLocation(Vector(x,y,z))	Set position
player.kick(reason)	player:Kick(reason)	Kick a player
mp.vehicles.new(model, pos)	Vehicle(pos, rot, "asset-path")	Spawn a vehicle
player.spawn(pos)	character:SetLocation(pos)	Spawn/teleport
entity.destroy()	actor:Destroy()	Remove an entity

Events

RageMP's event system maps almost 1:1 to HELIX events:

Blueprint

Blueprint— Networked events in BlueprintScroll to zoom · Drag to pan · Drag nodes to move

Lua

-- Subscribe to a server event (controller passed as first arg)
RegisterServerEvent('playerReady', function(controller)
    -- player connected and is ready
end)

-- Call from client to server
TriggerServerEvent('requestData', someValue)

JavaScript

// HELIX JS uses an endpoint/call model
Helix.server(async () => {
    Helix.endpoint('requestData', async (helixId, someValue) => {
        // handle the request
        return { data: someValue };
    });
});

// Client: call the endpoint
const result = await Helix.call('requestData', id, someValue);

Getting Started

1. Download HELIX and open HELIX Studio
2. Create a new package -- this replaces your RageMP resource
3. Port your scripts using the API table above (the event model is very similar)
4. Build your world in the UE5 editor instead of relying on GTA V's map
5. Deploy via Instant Hosting or on your own server
