So in the code below, I wanted to have an instruction screen come up first. Then, after the player "clicks" to start the game, I want to set another screen and populate my actors. I tried doing the populate stuff in the constructor but that doesn't work. Anyways, if the player accidentally double clicks, then everything is populated twice. How can I make sure the code under the act method only run once? Or is there a code I can have to check if its already been done and how the system would then ignore the "if click...do this.." code?
