The first article of Plants vs. Zombies on iOS devices developed on Mac using Cocos2D-x Engine

Today, let's take a look at the simple version of "Plants vs. botnets" running on iOS devices using the Cocos2D-x engine development, what I do is designed with two levels, start animation, menu interface, game interface, game Success Failure interface, the Start game button, exit game button, about Button, HELP button, and pause and return button are displayed on the menu. After completing the technologies used, I will summarize them. Now I will introduce the process from.
First of all, the environment to build this I will not say much, do not understand can find some information on the Internet, this information is still a lot, I use the Cocos2D-x version is 2.2.2, the environment is Mac Xcode4.6.2, so when creating a project, enter the/Users/tjj/Desktop/cocos2d-x/cocos2d-x-2.2.2/tools/project-creator directory under the terminal, enter the following command: python. /create_project.py-project PlantsVSZombies-package com.hdc.edu-language cpp. Then, press enter to create the project. Find the project name PlantsVSZombies in the projects directory and use Xcode to open it.
Create a StartLayer class to implement the animation start interface.
