Cocos2d-x 3.2 Lua sample CocosDenshionTest (audio test)

This blog introduces the Lua sample of Cocos2d-x 3.2 audio testing, the Cocos2d-x uses SimpleAudioEngine class to achieve audio control, such as playing, pause, stop and other operations. In the Lua code, the AudioEngine is used. For specific implementation, refer to the AudioEngine. lua file, but the SimpleAudioEngin is encapsulated.

Sample Code:

How to combine cocos2d-x with Lua to use specific points

The cocos2d-x comes with the lua engine. Look at this. Although it is English, it is easy to understand.
Cocos2d-x NEW Lua Engine README
Main features
Support autorelease CCObject object.
Call Lua function from C ++ (local, global, closure), avoid memory leaks.
Add CCNode: setPosition (x, y), CCNode: getPosition () huge performance boost.
Remove needless class and functions from tolua ++. pkg files, improved performance.
CCMenuItem events handler.
CCNode onEnter/onExit events handler.
CCLayer touch & multi-touches events handler.
Check the two connections.

Who can provide cocos2d-x + lua how to compile the file into Android

Er, in fact, many things in oc need Java to complete. coos2d is mainly used in the game. Most of them are similar. All the methods in sit-down are hitting and calling strings @, do not add the prefix in oc at the beginning of the code without importing the header file. In Android, there are imported class files. Basically, there is no difference between other files. You can skip to the Forum and ask for advice. You will soon be able to learn it! Wish you success!
