I am taking a screenshot of textureRect which is child of a viewport with the below code. I want to save the screenshot in the file system so that when I play the game next time, it starts from the saved screenshot.
var img = get_viewport().get_texture().get_data()
var tex = ImageTexture.new()
I want to save the current texture of the node textRect to file so that when I play the game next time the saved screenshot is loaded.
