Question by magical · Mar 04, 2013 at 05:22 PM · loadsave-to-file

Record x,y,z position of object in Textfile dynamically for playback

I want to record the position of a gameobject as it moves and load this back in if a certain event is triggered. This would then be applied to a different gameobject.

So if a cube were to be moved about by a user the position is recorded as it moves. When a certain event is triggered (on keypress for example) then a 2nd cube would be moved in the same way but from its own starting position.

I have looked at playerprefs but from what i understand this would only work for saving a single position and loading an object back to that position.

Is this sort of thing possible? If so is there a standard way to set, for example, the saving of the coordinates to be done every 0.1 seconds?

Being a newbie it is likely i just dont know the right keywords to be searching to figure this out myself. Any help in steering me in the right direction would be greatly appreciated.

You probrably need to make something better than Player Prefs, Id Recommend checking out this link: http://forum.unity3d.com/threads/44559-Saving-Game-beyond-PlayerPrefs-XML-ISerializable-etc

QUESTION: Are you trying to make it so the player can playback after leaving the game? If not, you can just store a List as a Static Member, and it will persist throughout the game (untill shutdown)

IE:

 public static List<Vector3>  myList;

or make a storage object and
DontDestroyOnLoad (yourStorageObject);

@kramcomposer Thanks for that i'm about to read that thread now. In answer to your question though, yes i need to playback AFTER the game has been closed. this functionality will be extended for something i want to do in a game but i need to first have a way to store and load the positions before i can make any progress.

The end result is multiple recordings that can be selected by a user, causing the 2nd object to basically have its recorded movements played back.
