I have 2 scenes that work like the menu and the game.
when I'm on the menu, when I click the "new game" button I execute the method
get_tree().change_scene("res://scenes/main.tscn")
to open the game.
When the game is over, I execute the method
get_tree().change_scene("res://scenes/inicio.tscn")
to go back to the menu.
After returning to the menu, the "new game" button no longer works, does not open the game. And i don't know what i am doing wrong. I read about this method "changescene" and i found some people saying: it's just call changescene(), and the method does the rest.
