This PHP design mode album from the blog (jymoz.com), now has no access, this series of articles I have been looking for a long time to find the complete, thanks to the author Jymoz's Hard Pay Oh!

Star Open map battle, wait 5 seconds to enter the map, each player will have a base, a few farmers, and there will be the initial population supply. But these are different depending on the race.

problem to be solved: We need to make different initialization for the players based on race, and it's best to encapsulate these different processing methods.

idea: define the initialized interface and then make the initialization classes for different races.

Example policy mode (strategy):

In order to make the code not too long, the definition of a subset of classes is not written here, and if you want to debug, replace new with a string.

<?PHP//player's class    classPlayer {//belonging to the race         Public $race; //troops         Public $army; //Building         Public $building; //Population Supply         Public $supply; //constructor, set the race to belong to         Public function__construct ($race)        {            $this->race =$race; }    }    //Initialized Interface    InterfaceInitialplayer {//the troops that made the initialization         Public functionGivearmy ($player); //construction of an initialized building         Public functionGivebuilding ($player); //Initialize population supply         Public functionGivesupply ($player); }    //the initial algorithm of insect clan    classZerginitialImplementsInitialplayer {//the troops that made the initialization         Public functionGivearmy ($player)        {            //a overlord            $player->army[] =NewOverlord (); //Four Zerg Farmers             for($i= 0;$i<4;$i++)            {                $player->army[] =NewDrone (); }        }        //construction of an initialized building         Public functionGivebuilding ($player)        {            //a base            $player->building[] =NewHatchery (); }        //Initialize population supply         Public functionGivesupply ($player)        {            //the initial population supply of the Zerg is 9 .            $player->supply = 9; }    }    //the algorithm of the initialization of the human race    classTerraninitialImplementsInitialplayer {//the troops that made the initialization         Public functionGivearmy ($player)        {            //Four human-ethnic farmers             for($i= 0;$i<4;$i++)            {                $player->army[] =NewSVC (); }        }        //construction of an initialized building         Public functionGivebuilding ($player)        {            //a base            $player->building[] =NewHatchery (); }        //Initialize population supply         Public functionGivesupply ($player)        {            //the initial population supply of the human race is ten            $player->supply = 10; }    }    //Initialize the control class    classInitialcontroller {//constructor, the argument is the player's array         Public function__construct ($playerArray)        {            foreach($playerArray  as $player)            {                Switch($player-race) {                     Case' Zerg ':$initialController=Newzerginitial ();  Break;  Case' Terran ':$initialController=Newterraninitial ();  Break; }                $initialController->givearmy ($player); $initialController->givebuilding ($player); $initialController->givesupply ($player); }        }    }    //Suppose two Zerg, one clan    $playerArray=Array(        NewPlayer (' Zerg '),NewPlayer (' Zerg '),NewPlayer (' Terran '),    ); //Perform initialization work    $initialController=NewInitialcontroller ($playerArray);?>

Usage Summary: The strategy mode can encapsulate the algorithms in different situations and invoke them according to the specific situation.

Implementation Summary: need an interface, specify the algorithm specification, the user (such as initialization) as long as the corresponding algorithm can be called.
