Split Screen Create

Use the PrisimMC (or MultiMC) launcher to import this pack from Modrinth. PrisimMC allows you to create separate instances (or multiple running copies) of Minecraft. You will need to download this pack for each instance that will be running.

To play on an external server, either the server must disable online mode or each player must use a different Minecraft account. You can also install the E4MC mod, which makes LAN worlds joinable by anyone like a server.

For local play, host a LAN server on the main instance of the pack. All of the other instances will need to join that local server.

If you only have one account to use, you will need to use the AuthMe mod to enable Offline Mode for both online and local multiplayer. Click on the lock icon in the Multiplayer menu to enter Offline mode. If you enter the name of a Minecraft Account, their skin will be used.

To put the windows into Split Screen, press F11. This cycles between different positions and sizes for each instance.

You may need to hide the taskbar to see the bottom of the screen.

To prevent the escape menu from automatically appearing, press F3+P to disable
pauseOnLostFocus.

On the Minecraft menu, click Options -> Controls -> and the Controller Icon to enter the Midnight Controls menu.

If that instance will be using a keyboard/mouse, turn off Auto Switch Mode.

If that instance will be using a controller, turn on Virtual Mouse. Then, open Controller Options on the sidebar to enable unfocused input.

If you only plan on playing with 1 controller, you can skip this step. We need to assign a controller to each instance of Minecraft. Switch the selected controller at the top of Controller Options to the controller for that instance.
