UnityDataReplay

A system for replaying recorded motions (position and rotation data) in Unity.

This script uses data recorded and saved using my UnityToMatlabUDP project (https://github.com/pryxe023/UnityToMatlabUDP).

How it works

The recorded data (see above) is in csv-files. This (Re)player allows you to move GameObjects based on the information in these csv-files.

CSV format

It is important that the format of your csv-files is as follows (from left to right);

1. Position X
2. Position Y
3. Position Z
4. Rotation X
5. Rotation Y
6. Rotation Z
7. Timestamp
8. Scale of recording (useful when playing on a scaled object)

Use

Simply add the GameObjectMotionReplay.cs and ReplayManager.cs files to your Unity assets.

Create GameObjects to be controlled by the scripts. Attach the GameObjectMotionReplay.cs to each GameObject. In this script, attach the csv-file containing the positional and rotational data to the correct GameObject.

Next, create an empty GameObject (and for simplicity call it 'Replay Manager') and attach the ReplayManager.cs script to it. Here you can change general settings and connect the replayable instances of GameObject to the manager.

That's it!

Future updates

Nothing in the works right now, but I might edit the script to find the correct values (position X, rotation X, etc. etc.) based on the headers in the csv-file automatically. This isn't difficult to implement, but not necessary for my needs currently. However, feel free to fork this project and implement it (or send me a message if you really want me to implement it).

Known issues

• Unity seems to be unable (sometimes) to play the replay fast enough. Added a 100 Hz maximum sampling frequency (line 109 in ReplayManager.cs) which seems to do the trick.
