Regular Expression Code Conversion Program for program porting between different cocos2d-x versions.

If the development environment does not have the reflection function, it takes a lot of effort to rename the code. The following code replaces variable names in batches. Modify many situations that can be used for code conversion.

This article is used for program porting between different cocos2d-x versions.

Main functions of the Code: exclude comments and strings, and replace other content with the variable name in the dictionary. Click Open Link
