Dynamic (Voronoi) Split Screen for Godot

This sample project showcases an implementation of dynamic split screen, also called Voronoi split screen, for both 2D and 3D games.

Check out this demo on the asset library: https://godotengine.org/asset-library/asset/541

Details

A dynamic split screen system displays a single screen when the two players are close but a split view when they move apart.

The splitting line can take any angle depending on the players' position, so it won't be either vertical or horizontal.

This system was popularized by the Lego video games.

How it works

Two cameras are placed inside two separate viewports and their texture, as well as some other parameters, are passed to a shader attached to a TextureRect filling the whole screen. 

The split_screen shader, with the help of the camera_controller script, chooses which texture to display on each pixel to achieve the effect.

The cameras are placed on the segment joining the two players, either in the middle if they're close enough or at a fixed distance otherwise.

How to use it

Open and launch the project inside the Godot engine, select either the 2D or the 3D demo from the menu and then use WASD/ZQSD keys to move the first player and IJKL/arrows keys to move the second one.

While a demo is running, you can press the escape key to get back to the menu.

The Cameras node has parameters to tune the distance at which the screen splits and also the width and color of the splitting line. The Adaptive Split Line Thickness parameter select whether the split line has a constant thickness or a dynamic one varying depending on the distance between the two players.
