Saving and Loading and assinging to gameobject

Hi Guys,

I have a question about saving data. I have created a class called Gamesettings that checks how many objects are in the scene with the tag Character. It then should give each of them a random ID. This part works.

In another class i have the save and load buttons that call the functions in this script. I want to save the unique ID's of every gameobject and then when you click on load it will instantiate a prefab and apply that unique ID. But for soem reason it either just get's a new ID or It keeps on instantiating gameobjects.

• Question for the future... if i can check what Unique ID a gameobject has. Can I then also give it his specific position? How would that be achieved in the best way?
