==============================================================================

Star battle reached the back, the map of the troops are many, if we take each soldier's image animation and property values as an object, the system memory will be very expensive.
We'll find out when we play, because there are only three races in the galaxy, but there are only dozens of of them.
Although the remaining blood of each individual soldier is different, the same class image animation is the same, even if different players, just different colors. Like everyone's machine-gun soldiers.
And most players only use some of the most commonly used classes, and many times they don't make all the classes.

problem to be solved: share the image animation of the class.

idea: We put the image animation model of each class as an object and put it into memory sharing. Once you have a screen with this class, just take the shared image animation and change the color.

Example of the Flyweight mode:

<?PHP//The machine gun to enjoy the yuan    classMarineflyweight {//Draw the image animation of the machine gun, parameters of the state, such as which player belongs to         Public functionDrawmarine ($state)        {            //draw a machine gun soldier        }    }    //enjoy the Yuan factory    classFlyweightfactory {//an array of elements for storing multiple privileges        Private $flyweights; //ways to get the benefits         Public functionGetflyweight ($name)        {            if(!isset($flyweights[$name]))            {                $flyweights[$name] =New $name." Flyweight "; }            return $flyweights[$name]; }    }    //initialize the enjoy meta factory    $flyweightFactory=Newflyweightfactory (); //when we need to draw a machine gun, we also pass a state array containing the remaining blood and so on .    $marine=$flyweightFactory->getflyweight ("Marine"); $marine->drawmarine ($status);?>

Summary of usage: enjoy meta-mode to centralize resources that need to be shared, manage them uniformly, and prevent duplication of consumption.

Implementation Summary: a shared resource is required to manage shares, such as the flyweightfactory above. The production of all shared resources is given to a factory.
