Cocos Creator v1.6.0-rc.1 Release:

Highlight Features

  • Upgrade the JSB engine to SpiderMonkey v52 and binding layer code, a substantial increase in Android platform performance
  • Game preview using bundle-free script compilation mode, regardless of the number of scripts included in the project, the compilation process can be done in 2 seconds.
  • Parse and cache BMFont data during asset import phase, results in a significant increase in the speed of the runtime instantiation of bmfont.
  • Replace websocket library on iOS platform with facebook/SocketRocket, to solve most of the iOS platform-specific disconnection and connectivity issues
  • When building Web platform, can choose to add an MD5 string to the output asset file name to resolve the problem that the client can not correctly update the cached assets.

Please make sure to backup your project before trying out beta release versions!

Please discuss any issue regarding v1.6.0 beta version in this thread. Thanks!



Great!!! Thanks!


Bug at v1.6.0_beta.3

ParticleSystem missing End Colour Var property


Awesome !
I wait for c++ and compelet typescript
Good job
Lovely 2d engine


Please add support for themes in editor. I never liked the cocos creator theme since beginning as much as the features of it. IMHO, good themes can easily make editor look premium and attracting other people to try it atleast. :slight_smile:


today i installed 1.6.3 beta
i added a typescript in empty project everything was fine!
when i change the name from NewScript to Hero
i got bug


no action filter or goes focus in Assets view anymore when click it


Customizable theme is planned.


Fixed in next release.


request for save and restore View Layout
it will be good for Portrait and Landscape Scene View for development


If you have modified panel layouts it will be saved and restored automatically.


fix done, will be repaired in the next version.


Using auto atlas in project even with max height, max width of 1024 will have such error on web build:

Note: Same configuration works on v1.5.2


Build web-mobile release mode will stuck at cut-engine for sometime before build continues. Is this normal?


Cut-engine phase is to build engine bundle according to module configuration in Project Settings. It’s a big bundle so normally will take a while. But once you’ve done building and don’t modify module configuration it will skip that phase for future builds.


Fixed in next release


When there’s an invalid import, project will fail to start up. Using v1.5.2 would still start up the editor and prompt error, but v1.6.0-beta.3 wouldn’t even open. Could be reproduced by importing an invalid script:

import SomethingNotValid from 'SomethingNotValid';


When we use es6 class syntax on our custom classes. Editor will complain such warning:

ctor of CCClass 'undefined' should not accept any arguments.

Sample es6 class:

class Rectangle {
  constructor(height, width) {
    this.height = height;
    this.width = width;


What does these mean?

Introduced global variable while editing: i
