How to create a Replay System like in Super Meat Boy using Unity
In this video, I show how to create a replay system similar to the one in Super Meat Boy using Unity. We'll start with replaying a single playthrough and then expand the system to handle replaying each attempt at the level.
The example in the video is done using a platformer-styled game; however, the concepts and logic in this tutorial will apply to most other types of games as well.
Thank you for watching and I hope the video was helpful! 🙂

► RESOURCES
This is an excellent resource which goes over some more complicated topics like Memory Streams in a Replay System. I highly recommend giving it a look, especially if you're trying to optimize for memory.

If you're struggling with the event-driven stuff used in this tutorial (onGoalReached, onRestartLevel, etc...), this is a short and excellent video that will bring you up to speed with how I'm using events in this project.
