Set Player (KinematicBody2D) position after saving it

DarkLeksis

Hello, For my first project using Godot i'm trying to reproduce the game 'Jump King' I created a automated system that work but now i'm trying to make the loading system. By pressing a 'continue' button i read a file that store a position and i apply it on a kinematic body from another scene. The scene seems loading but the player is not moved. Here's my code for the pressed button (my player has a methods set_saved_position(new_pos): position=new_pos)

    
        var save_path = 'user://save.dat'
        onready var player = get_tree().get_root().get_child(0)
        
        func _on_Continue_pressed():
        	var data = {}
        	var file = File.new()
        	if file.file_exists(save_path):
        		var error = file.open(save_path, File.READ)
        		if error == OK:
        			data = file.get_var()
        			file.close()
        		var _y = get_tree().change_scene("res://scene/Level.tscn")
        		print(data)
        		player.set_saved_position(data["Pos"])
        	else:
        		var _y = get_tree().change_scene("res://scene/Level.tscn")

After testing, i've the good position and i know that the program run the 'if' statement Thanks you in advance for your help

I don't think the function will keep running after you change the scene, so the variable is lost. You might want to look into doing the saving or at least storing the variable in an autoload scene. There are tutorials on using autoload on youtube.

Misunderstood:

I've put a print('test') after the scene change and everything seem's working so i dont think that's the case :/

Corrected:

I've copied the line player = get_tree().get_root().get_child(0) after the loading of the scene to create a new instance but nothing changed

You would have to put the print in a script in the new scene, like one attached to the world node or whatever. Like in the _ready function. That's where you could load and position the player from the save. Assuming the position works from a load in the current scene, it's really the only explanation.
This is a common problem you can check here: https://godotengine.org/qa/1883/transfering-a-variable-over-to-another-scene
