When we play Star Quest or stand-alone with the computer, sometimes we suddenly leave the game, or in front of the troops, need to save the game.
So what do we do to save the current information? And at any time, you can restore the saved game?

problem to be solved: Save All the information of the game and restore it completely if it is restored.

idea: Create a class that specifically preserves information so he can handle these things like a memo.

For the sake of simplicity, we use this information to restore a player to demonstrate.

Memo (Memento) mode example:

<?PHP//Memo Class    classMemento {//Crystal Mine         Public $ore; //Gas Mine         Public $gas; //all of the player's Army objects         Public $troop; //all building objects of the player         Public $building; //constructor, parameter is the object of the player to be saved, the type of the force argument here is the player class         Public function__construct (Player$player)        {            //Save this player's Crystal mine            $this->ore =$player-ore; //Save this player's gas mine            $this->gas =$player-Gas ; //Save all of the player's Army objects            $this->troop =$player-Troop; //Save all building objects for this player            $this->building =$player-Building; }    }    //player's class    classPlayer {//Crystal Mine         Public $ore; //Gas Mine         Public $gas; //all of the player's Army objects         Public $troop; //all building objects of the player         Public $building; //get this player's memo object         Public functionGetmemento () {return NewMemento ($this); }        //Use this player's memo object to restore this player, here the mandatory parameter type is memento class         Public functionRestore (Memento$m)        {            //Crystal Mine            $this->ore =$m-ore; //Gas Mine            $this->gas =$m-Gas ; //all of the player's Army objects            $this->troop =$m-Troop; //all building objects of the player            $this->building =$m-Building; }    }    //make a player    $p 1=NewPlayer (); //Assuming he's now picking up 100 crystal mines.    $p 1->ore = 100; //Let's save the game and continue playing the game.    $m=$p 1-Getmemento (); //Assuming he's now picking up 200 crystal mines.    $p 1->ore = 200; //We are now loading the original saved game    $p 1->restore ($m); //output Crystal ore, you can see that it has become the original preservation of the state    Echo $p 1-ore;?>

Usage Summary: The memo mode allows us to save information for a moment, and then restore the information needed, just as the game is saved and loaded into the archive.

Implementation Summary: a memo class is required to hold the information, the saved class needs to implement the method of generating the memo object, and the method of invoking the memo object to restore its state.
