Save and load player posituon

Question

Need help to create a save and load system to retrieve the players position

Answer 1

To save and load game states you should learn about the File class: https://docs.godotengine.org/en/3.1/classes/class_file.html
Take variables from your nodes and write them to the file.
Then to load, read the file and set back the variables in your nodes.

The documentation even has an example of how to save games: https://docs.godotengine.org/en/3.1/tutorials/io/saving_games.html
