Godot Rewind Mechanic

Note

Experiment to implement rewind mechanic in Godot engine. It's all pretty messy right now. But the essentials for the rewind effect are rewind_system.gd and rewinder.gd.

Controls

movement - WASD

rewind - Shift

How it works

You basically record a limited amount of data, popping the oldest entry when you reach the maximum amount of recorded data.

This data, includes position and other rewindable data depending on the situation.

Implementation

The rewind effect is created by adding a plain Node as a child of the Node2D you want to be able to rewind and attach the rewinder.gd script to it. The rewinder.gd script records only the global_position of it's parent node (i.e. the Node you want to rewind).

You can however, extend the rewinder.gd script and override the __record() and __rewind(data) methods, to specify the data you want to record. An example of this is in player_rewinder.gd.
