Dynamic Split Screen

This sample project showcases an implementation of dynamic split screen, also called Voronoi split screen.

Language: Godot shader language and GDScript

Renderer: Forward Mobile

Details

A dynamic split screen system displays a single screen when the two players are close but a splitted 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 videogames.

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 SplitScreen shader, with the help of the CameraController script, chooses wich 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, then use WASD to move the first player (in red) and IJKL (or arrow keys) to move the second player (in blue).

The camera_controller.gd script sets parameters to tune the distance at which the screen splits and also the width and color of the splitting line.
