Cocos2d-x 3.2 Lua sample FontTest (FontTest)

This blog introduces the FontTest example in the Lua test project in Cocos2d-x 3.2, mainly using a font file to create the font style we want:

The first parameter is text, the second parameter is the ttf font file, the third parameter is the font size, the fourth parameter is the block size, and the fifth parameter is the text horizontal alignment, the sixth is vertical text alignment.

Example:

Sample Code: (Note: a separate file cannot be run. For details, refer to lua-tests)

When creating a cocos2D-x project in VS2010, Select Lua support: Support Lua (Hook), an error is reported after generation,

Some library files are not properly loaded. Find the corresponding library file and paste it to the corresponding location. Do not forget to check whether the file has permissions.

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.
