Using Dashboard we can create a new project with Hello World project template. Let's use the project to learn the structure of a Cocos Creator project.
Your Cocos Creator project should look like this:
ProjectName (project root)
Let's see what these folders do:
assets contains all art assets, script files and third party modules. Only files in
assets folder will be shown in Assets panel of editor. Once imported to the project, a
.meta file with the same name will be generated for each file in
.meta files are used to store the corresponding resource configuration and index information. The
.meta file needs to be submitted to the version control system, please refer to Resource Management Considerations --- meta files for details.
Some third party project files such as
.tps from TexturePacker, or
.psd from Photoshop should be put outside of
assets since we won't use them directly in our project.
library folder is generated once the project is first opened and imported. In this folder, all assets of the game are renamed with their UUID (universal unique identifier) and will be copied over when the game is published.
library is damaged or missing, you can safely delete the
library folder and reopen the project to re-generate it.
local folder contains all settings that should not be shared across computer. Most of them are personal preferences such as Editor layout, window size and position. You should not use or modify the content of this folder.
packages folder is used to place custom extensions for this project. If you need to install the extension manually, you can create this folder manually. If you need to uninstall the extension, delete the corresponding folder in
settings folder contains project related settings such as bundle name, bundle id and target platform settings in Build panel.
temp is a temporary folder used to cache local temporary files of Cocos Creator. This folder can be deleted manually after closing Cocos Creator, and you don't need to care about what's inside.
project.json, along with
assets folder, are the only two necessary requirements for validating a Cocos Creator project. Only folders containing
assets can be opened as Cocos Creator projects. You should not change the file manually, and you don't need to care about the contents inside.
build folder will be created once you use main menu
Project -> Build... and publish your game with default build target. If you have built for native platforms, this
build folder will be very large.
When Cocos Creator creates a new project, it will automatically generate a
.gitignore file to exclude files that should not be submitted to the git repository. If you use other version control systems, or need to submit project to other places, you should pay attention to only submitting
project.json, or other manually added association files.
