index

Console outputs editor or engine messages, including log, warn, and error. Different types of messages are displayed in different colors.

  • console.log(): outputs log, gray text, usually used to show what action is in progress.

    log

  • console.warn(): outputs warnings, yellow text, used to indicate exceptions that the developer would be wise to handle, but which will not affect operation if left unhandled.

    warn

  • console.error(): outputs error, red text, indicating a serious error that must be resolved before proceeding to the next step or running the game.

Custom output information

To make it easier to locate files, nodes or assets, or to provide links to jump to help documentation, etc., Cocos Creator supports custom output to the console log in Developer -> Developer Tools in the editor's main menu, which currently supports output of the following:

  • Jump to links by URL
  • Show images by URL
  • Locate assets by URL or UUID
  • Locate nodes by UUID
  • Locate script files by disk file path
  • Output the text in the corresponding language

Data format

Depending on the output content, the input data formats include the following two:

  • {type[text](url)}
  • {type(text | url | uuid | path)}

The data formats are described as follows:

  • Matches the characters in {} as a whole.
  • [text]: Text of the jump link, optional.
  • type: The type of information to be output, including the following. The filling is case-insensitive, and if not fill in, the input is directly output without format.

    • link: external jump link
    • image: display image
    • asset: locate to a asset
    • node: locate to a node
    • i18n: multilingual translation

Example

Open Developer -> Developer Tools in the editor's main menu, then type:

console.log('Open {link[the help doc url](https://docs.cocos.com/creator/manual/en/editor/console/)}');
console.log('Locate {link[ the file in library](D:/cocos-creator/a/library/36/36b55a90-1547-4695-8105-abd89f8a0e5f.js)}');
console.log('Locate Node UUID {node(f6zHdGKiZDhqbDizUsp8mK)}');
console.warn('Locate Asset UUID {asset(17185449-5194-4d6c-83dc-1e785375acdb)}');
console.error('Locate Asset URL {asset(db://assets/animation.anim)}');
console.log('The URL is {asset[{asset(db://assets/animation.anim)}](db://assets/animation.anim)}');
console.log('Show image {image(https://forum.cocos.org/images/logo.png)}');
console.log('Translate: {i18n(console.description)}');
