LIMSCAPERS Multiplayer Beta

How to Start Multiplayer

LIMSCAPERS levels can be played together through Open Multiplayer or Private Multiplayer. This guide explains how to enter a room, share an invite URL, and understand the room system.

Starting from a LIMSCAPERS detail page

Multiplay option on a LIMSCAPERS level detail page — Click the Multiplay option on the level detail page of the LIMSCAPERS website.

Starting from inside the LIMSCAPE app

Opening the LIMSCAPERS window inside LIMSCAPE — You can also enter multiplayer from the LIMSCAPERS window inside the app. The LIMSCAPERS window can be opened from the pause menu or from the level editing window.

Multiplay URL field in the LIMSCAPERS window — When the LIMSCAPERS window opens, paste the invite URL into the Multiplay URL field at the bottom, then press the JOIN button to enter the room.

Rejoining and managing a session

Rejoin Multiplayer and New Room buttons in the menu level — After you enter multiplayer once, the multiplayer session is saved to the menu level. To rejoin Private Multiplayer, use the **Rejoin Multiplayer** button. You can also create a room from this screen with the **New Room** button, and a button for joining Open Multiplayer will also be shown. Normal single player remains available from the large white play button. If you saved when leaving multiplayer, the last state can be restored and uploaded to LIMSCAPERS. When rejoining Private Multiplayer with no other participants in the room, the level starts from its initial state, but it can be restored if the previous cache is still available. If other participants are already in the private room, your level state will be synchronized to the active session.

Multiplayer window with invite URL, chat, participants, and device settings — During multiplayer, you can use the multiplayer window. Press **Alt+C** to open it. From this window, you can check and copy the Invite URL, use chat, check the participant count, check the amount of edit-list data in the current session, and configure webcam or microphone settings. Chat messages are delivered to all participants. Only messages sent after you joined are shown; past conversation history is not displayed.

Technical Notes

LIMSCAPERS multiplayer uses WebRTC and peer-to-peer communication. LIMSCAPE apps exchange data directly with each other without routing gameplay data through a central server. Because of this, some network environments may not be able to connect, such as networks using symmetric NAT.

In LIMSCAPE Private Multiplayer, the original level is shared as the starting point, and world state is synchronized by sharing edit history on top of that level data.

Edited information can be saved, so you can continue playing the edited state in single player after saving. However, as the edit history grows, the initial synchronization time for new participants will become longer. After making many edits, we recommend uploading the level to LIMSCAPERS again as a new version and restarting the session from that updated level.

Multiplayer can also be used when the LIMSCAPERS publish status is Private. You can upload a level privately so it does not appear in the LIMSCAPERS list, then share and create together with friends or collaborators.

Multiplayer Room URL Format

LIMSCAPERS multiplayer rooms are separated by the URL and the following query values.

URL: The base LIMSCAPERS level URL.
mpid: The room ID.
lvid: The initial level ID. This is added automatically.
ptv: The LIMSCAPE protocol ID. This is added automatically and may change when the app communication protocol receives a major update.

Users can enter the same room only when all four values match. For example, if a level is updated on LIMSCAPERS, players using the old level data will be separated from players using the new level data. If the LIMSCAPE app protocol ID is updated, users will also be assigned to a different room.
