I am trying to make a game like the escapa game you might have seen on the internet. I have got all the movement pretty much sorted its just I cannot get the game to restart. I am relatively new the AS3 so bear with me on this. I have a Main class, an enemy class, a player class and a button class. The button class creates the restart button and from the main class, when certain conditions are met, an event listener is added to this button instance to say “on click… do this…”. I do not no what to put to make it reset the game however. I have tried to clear all the objects when the game is over but I cannot get the game to restart on click. I figured if I can just add a new Main class instance then the game would be reset but I cannot seem to do it… Any help would be greatly appreciated (sorry if my code is a bit messy).Here are the classes I have made:
