Take a look at the official website and the documents. It's interesting to see cocos JS and think that you can copy an example to play with. Although the bottom doesn't know what to do, at best, it's the feeling of writing a configuration file.

Complete the first game according to the example given on the official website

Download cocos creator and install

Download the initial file given in the tutorial, which is the music and image component. Create a new canvas, and then drag the background and other pictures up
