Splitscreen Support

A simple mod that significantly simplifies the organization of local multiplayer in Minecraft through automatic window positioning.

Main Functionality

After installing the mod, pressing the F11 key (toggle fullscreen) allows you to cycle through different window placement options - half and quarter sizes for split screen. The selected position is saved and automatically restored on the next game launch.

This feature is ideal for simultaneously running multiple copies of Minecraft with automatic window positioning for comfortable co-op gameplay.

Recommended Configuration

Required Components

• Two or more licensed Minecraft accounts
• PrismLauncher
• Midnight Controls mod for gamepad management
• Splitscreen Support mod
• Two or more game controllers
• Friends for co-op play
• Large TV connected to computer
• Comfortable couch

Step-by-Step Setup

Create multiple Minecraft instances in PrismLauncher - one for each account. Install Splitscreen Support and MidnightControls mods in each instance.

Launch all instances and configure each as follows:

• Splitscreen Support: Press F11 to position windows
• MidnightControls: Enable Unfocused Input and Virtual Mouse options according to official documentation
• Minecraft: Press F3+P to disable Pause on Lost Focus function

Configure gamepads for each instance through MidnightControls. In one of the instances, create a new world and open it to LAN. Connect the remaining instances to this world (for example, via localhost:25565) - and you're ready for a fun Minecraft party!

Additional Features

The username is displayed in the upper left corner of the main menu, helping to distinguish which window belongs to whom.

Adjusting Window Gap

By default, a small gap is left between windows. The width of this gap can be changed (down to 0) through the gap parameter in the config/splitscreen.properties file. This file is created automatically after the first game exit with the mod installed.
