I created an button icon and tap to start text and when player taps it will start the game and it will disappear and now when game is over i want it to be restarted as it was but i am geting errors !

also I don’t understand why in my player code is node2d not characterbody2d?
What errors are you having? It would help a lot finding the issue, mostly because error messages usually come with the line of code it comes from.
About that:
also I don’t understand why in my player code is node2d not characterbody2d?
That’s probably because your player node is a generic Node2D and not a CharacterBody2D. If you changed your node afterward to be a CharacterBody2D, you can then change the line to extends CharacterBody2D.
Keep in mind that a player does not have to be a CharacterBody2D; it’s just a built-in script that’s very convenient as it handles a lot of stuff for you, but you can absolutely create a player controller with a Node2D if that fits. All depends on your needs.
Invalid call. Nonexistent function 'set_orbit_center' in base 'CharacterBody2D'.

also yes i changed my player to characterbody2d i mean if it will not cause any problem i will not change the node2d to characterbody2d
That’s weird, if you added the player.gd script to your player node, that should work fine. Could you delete the Player node from your Main scene and add it again? To make sure there’s no overridden value on the instantiated scene.
That error means that $Player is null. It can be related to the player node having being freed, or not being found using the $ syntax.
Since you’re storing your player in the player variable, I’d suggest you use it instead:
player.call_deferred("enable_camera")
Not sure that will fix the problem, but since you’re also using the player variable on the line just above with no error, I guess that will help.
nah it fixed all problems, but it don’t spawn circles after starting again but i think i can fix it alone, only if you don’t mind can you help with this? I don’t understand why my player looks of after deleting it and adding again?
In your main script, you’re doing this on game over:
player = preload("res://Scenes/player.tscn").instantiate()
player.position = current_orbit_pos
add_child(player)
So I guess the current_orbit_pos may not be the position you want to set your player to?
Tbh I don’t know how your game over/restart should behave as it’s more of a design topic than a programming topic, so I don’t know if I could help more here
