What software do you need to teach yourself two-dimensional animation and what do you need to prepare?

I suggest you learn Flash software. The preparations are as follows:

1, computer, mid-range configuration, not too good, but not too bad, otherwise the post-processing will be helpless;

2, connect to the network, download a Flash8 on the Internet, and the cracked version is enough;

3. Search and download some Flash production tutorials, join Flash forums or learning websites, or buy some books and tutorials, or learn by yourself through the help files that come with the program;

4, it is best to get expert advice, which will be 100 times more efficient than getting there yourself;

5, pay attention to accumulate some materials, procedures and means, distribute them, and you will feel comfortable publishing your works in the future.

Wish you success!
