From MTA

MTA and DarqlineMP both run Lua resources with a manifest, events and exports, so server-side resources port with few structural changes. The main differences:

• No client scripts. Client-side Lua, its GUI and triggerClientEvent have no equivalent. Use the built-in dialogs, menus and HUD widgets, or a view: an HTML page of your resource that exchanges actions and data with your server code.
• Elements are typed handles. Instead of one setElementPosition(element, ...) for every element type, each type has its own calls: player:teleport, dlmp.set_vehicle_position, object:set_position.
• cancelEvent() becomes a return value. A handler cancels a cancelable event by returning false.
• Manifest. meta.xml becomes resource.toml; <script type="server"> is [server] scripts, <export> is [server] exports, <include> is [server] dependencies.

See Moving a game mode for the other differences. Below is a draft mapping of the main functions and events.
