As mentioned before, I sent it to git today and explained it.
These two classes are written according to the corresponding class in as3, so the usage is the same, and there is a complete example for reference, address: http://git.oschina.net/lonewolf/lufylegendLib.
Because JavaScript does not support the get and set attributes, the related attributes are changed to methods. For example, the repeatcount attributes are setrepeatcount and getrepeatcount. Everything else is the same. For details, refer to the source code and have detailed comments, which should be easy to understand.
The other two classes have already been submitted to lufy, but he is busy with version 2.0, so he does not have time to review the Code. If the code goes well, he will get version 2.1 as early as possible, so download the useful friend first.
Added two extension classes lmovieclip and ltimer for the lufylegend engine.
