Thanks for this Aum George. I tried out the replay/record functions, and made it so the text files remain saved. But then, if I start the demo again, and hit play, the engine crashes. How would I play back certain entities from different already saved .txt files? I'm looking to use this for before race camera runs around the level. So to load up a level, record the camera runs in different text files, then play each one before the race for the camera entity.
