Cocos2d-x Plants vs. Zombies (1) (Map loading)

//I am here to write an article is want to share experience with you, but I personally feel, the front I write is part of the code, even if you see, may feel I write too messy, no chapter can follow; I started writing, didn't think too much of the structure and hierarchy, so that the code seems very redundant When I look at someone else's blog, especially Jack's blog, I appreciate his structural pattern, and the level is very distinct, although I have written the fourth part about plants vs. Zombies. But I'm going to write it anew;

and the implementation of the code to write a word to the top of the blog, to facilitate the novice's learning is also conducive to master's guidance; look forward to more exchanges this time, I do not intend to use the background map, but the use of maps, the structure of the game is like this: it temporarily first contains a main scene; Today, to achieve is to load the map and change the size of the window, (the following work must be done in the Cocos2d-x game engine set up conditions, I use 2.2v);

First create the game scene class: Gamescene inherit Ccscene;

GameScene.h

#pragma once
#include "e:\cocos2d-x\cocos2d-x-2.2\cocos2d-x-2.2\cocos2dx\layers_scenes_transitions_nodes\ Ccscene.h "
#include" cocos2d.h "
class Gamescene:p ublic cocos2d::ccscene
{public
  :
	Gamescene ( void);
	~gamescene (void);
	Create_func (Gamescene); Creates a create method that contains the Initialize init () method of
	virtual BOOL init ();
};

GameScene.cpp

#include "GameScene.h"
using_ns_cc;
Gamescene::gamescene (void)
{
}
gamescene::~gamescene (void)
{
}
bool Gamescene::init ()
{
	if (! Ccscene::init ())//Overriding the Init () method in the base class
	{
            return false;
	}
	return true;
}

Next we modify the AppDelegate.cpp,

First include GameScene.h

#include "AppDelegate.h"
#include "HelloWorldScene.h"//We still try to keep the engine comes with HelloWorld files without having to change or delete it
#include " GameScene.h "//Is here (including GameScene.h)
using_ns_cc;
Appdelegate::appdelegate () {

}
appdelegate::~appdelegate () 
{
}

Change one More place:

BOOL Appdelegate::applicationdidfinishlaunching () {
    //Initialize director
    ccdirector* pdirector = Ccdirector :: Shareddirector ();
	cceglview* Peglview = Cceglview::sharedopenglview ();
	Pdirector->setopenglview (Peglview);
    Turn on display FPS
    pdirector->setdisplaystats (true);
    Set FPS. The default value is 1.0/60 if you don ' t call this
    pdirector->setanimationinterval (1.0/60);
    Create a scene. It's an Autorelease object
    ccscene *pscene = Gamescene::create ();///It's Here (change Helloworld::scene () to Gamescene::create ( ));
    Run
    pdirector->runwithscene (pscene);
    return true;
}

OK here can produce an empty black window;

The following is to write the main game layer, plus a class gamelayer; The following is his. H. CPP file

GameLayer.h

#pragma once

#include "E:\cocos2d-x\cocos2d-x-2.2\cocos2d-x-2.2\cocos2dx\layers_scenes_transitions_nodes\cclayer.h"

#include "cocos2d.h"
class Gamelayer:p ublic  cocos2d::cclayer
{public
:
	gamelayer (void);
	~gamelayer (void);
	virtual BOOL init ();
	Create_func (Gamelayer);
};

GameLayer.cpp

#include "GameLayer.h"
using_ns_cc;
Gamelayer::gamelayer (void)
{	
}
gamelayer::~gamelayer (void)
{
}
bool Gamelayer:: Init ()
{
	if (! Cclayer::init ())
	{
		return false;
	}
	return true;
}

below we add the main game layer to the gamescene scene;

Just add the following code to the GameScene.h;

#include "GameLayer.h"

void Initgamelayer (); This declares a function of initializing the game layer.

we define in GameScene.cpp; void Initgamelayer ();

void Gamescene::initgamelayer ()
{
	gamelayer* gamelayer = Gamelayer::create ();
	This->addchild (Gamelayer);
}

Finally, add the defined function to the bool Gamescene::init ().

This->initgamelayer ();

Next we will create a map layer Maplayer, create a map in the layer, and add to the Gamelayer main layer;

MapLayer.h

#pragma once
#include "e:\cocos2d-x\cocos2d-x-2.2\cocos2d-x-2.2\cocos2dx\layers_scenes_transitions_nodes\ Cclayer.h "
#include" cocos2d.h "
class Maplayer:p ublic cocos2d::cclayer
{public
:
	Maplayer ( void);
	~maplayer (void);
	Create_func (Maplayer);
	virtual BOOL init ();
	void Initmap ();//Initialize map function
	cocos2d::cctmxtiledmap* _map;//Declare global variables of map
};

MapLayer.cpp

#include "MapLayer.h"
using_ns_cc;
Maplayer::maplayer (void)
{
}
maplayer::~maplayer (void)
{
}
bool  maplayer::init ()
{
	if (! Cclayer::init ())
	{
	    return false;
	}
	This->initmap ();
	return true;
}
void Maplayer::initmap () 
{
	this->_map =cctmxtiledmap::create ("MAP_LIST.TMX");//Map files are made by the tile software, This piece should not be difficult, this map                                                           uses two layers of
	this->addchild (THIS->_MAP);
}

Let's add our map layer to our main game layer.

Add the following code to the GameLayer.h

#include "MapLayer.h"

maplayer* _maplayer; Declare map layer global variable
void Initmaplayer ();//Declare Initialize Map

Defined in GameLayer.cpp

In the GameLayer.cpp constructor: perform the following initialization

Gamelayer::gamelayer (void)
{
	this->_maplayer =null;
}

define void Initmaplayer ();

void Gamelayer::initmaplayer ()
{
	this->_maplayer =maplayer::create ();
	This->addchild (This->_maplayer);
}

Adding an initialization map to the bool Gamelayer::init ()

This->initmaplayer ();

Good to this one can show a map of the game: look at the effect:

It's so big, I want to show all the maps, and then we need to change the AppDelegate.cpp,

BOOL Appdelegate::applicationdidfinishlaunching () {
    //Initialize director
    ccdirector* pdirector = Ccdirector :: Shareddirector ();
	cceglview* Peglview = Cceglview::sharedopenglview ();
	Peglview->setframesize (1350, 500);//Is Here we modify the drawing window, note that the position can not be mistaken
	Pdirector->setopenglview (Peglview);
	

Here is the effect diagram after modifying the window:
