终于效果图:

Cocos2d-x-3.3 Mac 安装

下载地址:

參考文档:  

在线API列表: 

Cocos2d-x-3.3 版本号

从配置安装到创建项目都是命令行

• 官网下载最新版本号Cocos2d-x-3.3,大小约为280M 
• 
  
• • 解压后,在【终端】中切换文件夹到 解压后的文件夹,然后运行./setup.py,回车,例如以下图所看到的.
  
• • 期间会有几次询问,是否要设置安卓SDK路径,
  • 假设尚未安装Android开发环境,能够直接Enter跳过,暂不设置
  • (将来  能够在以下的文件里,进行配置:/etc/profile)
  
  

1 2 3

->Please enter the path of NDK_ROOT (or press Enter to skip): ->Please enter the path of ANDROID_SDK_ROOT (or press Enter to skip): ->Please enter the path of ANT_ROOT (or press Enter to skip):

依据提示,敲击命令:

source /Users/history/.bash_profile

然后Enter,这样就算设置好了.

1	Please execute command: "source /Users/history/.bash_profile" to make added system variables take effect

• 最后就是创建project.
• 继续命令行
• cd tools/cocos2d-console/bin,
• 接着使用以下命令就可以:
• cocos new project名 -p 包名 -l 语言 -d 目标目录,
• 比如 :

• cocos newcocos2d_x -pcom.beyond -lcpp -d /Users/beyond/Desktop/project

• 
  
• 运行后就有例如以下提示,表示OK~

1 2 3 4 5 6

Running command: new > Copy template into /Users/beyond/Desktop/project/cocos2d_x > Copying cocos2d-x files... > Rename project name from 'HelloCpp' to 'cocos2d_x' > Replace the project name from 'HelloCpp' to 'cocos2d_x' > Replace the project package name from 'org.cocos2dx.hellocpp' to 'com.beyond'

打开自己主动创建好的项目

能够选择桌面应用,直接command+R,编译执行

等了n分钟过后,最终跑出来了~

兴许补充一下:NDK文件夹的配置

进入终端,输入命令:sudo nano /etc/profile

打开配置环境变量的文件

依据实际情况,加入NDK_ROOT、ANT、SDK文件夹

终于，示比例如以下：
