What’s new

Cocos Creator 2.4.3 is finally here! This update brings great new features and performance improvements, such as support for nested use of Prefab and support for Android x86_64. In addition, it fixes problems since version 2.4 and improves the stability of the editor. I hope everyone can use Can be more handy and get twice the result with half the effort.

It supports nested use of other Prefabs in a Prefab, thereby reducing the number of duplicate resources and making it easier to maintain and update.

Upgrade Tips

Upgrading a project from a previous version of Cocos Creator is irreversible. Please backup the old version of the project before upgrading.

Projects under development can usually be upgraded seamlessly, but because of the uniqueness of each project, developers should conduct a technical evaluation based on their project’s own needs. If developers encounter difficulties in upgrading, please feel free to give us feedback and we will try our best to assist. In addition, due to stability considerations, it is recommended that projects that are about to be launched or already launched be upgraded with caution.

Upgrade from <2.4.0 version

  • cc.loader is no longer recommended, please use the latest cc.assetManager instead, please refer to the Resource Management Module Upgrade Guide

  • The sub-package function has been upgraded to Asset Bundle, please refer to the Resource Subcontract Upgrade Guide

  • Adjusted the directory structure after the project is built and adjusted the API of BuildResults. If you use the editor plug-in to get the editor’s build results, please refer to Customized Project Build Process Upgrade Guide

  • The cc.RawAsset that was deprecated since 1.10 has been officially removed, please use cc.Asset instead. Since 2.4 is no longer compatible with the legacy usage of the RawAsset type in the original 1.x project, it is recommended that all projects to be upgraded to 2.4, especially those upgraded from version 1.9, be edited in any 1.10 ~ 2.3 version. All warnings or errors output when the compiler compiles the code are processed correctly, and then upgraded to 2.4.

  • cc.Color.fromHex is deprecated, please use cc.Color.fromHEX interface

Upgrade from < 2.3.3 version

  • The CCTexture2D and CCTexture2DRGB methods in the Effect have been abandoned.

  • Vec3.FRONT has been abandoned, please use Vec3.FORWARD instead.

Upgrade from < v2.3.0 version

Since v2.3.0, Android and Android Instant use the same build template, please note:

  • If the code is used solely by the Android platform, please put it in the app/src directory, and the third-party library used by itself, please put it in theapp/libs directory.

  • If the code and third-party libraries used by Android Instant are separate, please put them in the game/src, game/libs directories.

  • For code and third-party libraries shared by Android and Android Instant, please place them in the src and libs directories under the proj.android-studio root directory, respectively.

  • proj.android-studio under the root directory jni/CocosAndroid.mk, jni/CocosApplication.mk, mainly used to configure engine-related configuration, developer configuration, it is recommended that Android be placed in app/jni/Android.mk and app/jni/Application.mk, Android Instant, please put in game/jni/Android.mk and game/jni/Application.mk.

  • When Cocos Creator compiles for Android, it will execute assembleRelease/Debug by default, and when compiling for Android Instant, it will execute instant: assembleRelease/Debug.

In addition, when Cocos Creator compiles for Android, it will execute assembleRelease/Debug by default, and when compiling Android Instant, it will execute in``stant:assembleRelease/Debug.

If you have customized the pause logic when switching between audio background and background, please remove it after upgrading to 2.3.0 Currently Cocos Creator games automatically pause and resume audio internally when switching between front and back on all platforms. If the developer has customized this block before, and listens for and performs audio operations like cc.audioEngine.pause() and resume(), it may conflict with the engine’s default behavior. If you encounter related audio issues, simply remove the corresponding custom code.

Upgrade from version v2.0 – v2.3.0

Starting from 2.3.0, the Canvas component is no longer responsible for setting the Canvas node size to the screen size. This behavior will be implemented in conjunction with the Widget component. To ensure compatibility, after the 2.0 project is upgraded, the node where Canvas is located will automatically add Widget components. (No problem upgrading from a 1.0 project)

Upgrade from < v2.2.0

Starting from 2.2.0, we have strengthened the memory management mechanism, and now require users to dynamically create cc.Node which is independent of the scene node tree through code must be released through destroy(), otherwise the engine cannot know when to recycle this type The memory of the node will cause a memory leak.

  • In addition, the nodes that are manually removed from the scene need to be unified when they are not needed.

// Assuming testNode is a node in the scene, if it was manually

// removed from the scene before, such as

testNode.parent = null;

// or

testNode.removeFromParent(true);

// or

parentNode.removeChild(testNode);

// If testNode will be used again in the future, there is no need to

// manually destroy the node otherwise it should be called manually

testNode.destroy();

  • If a node is managed via cc.NodePool, it is not affected.

Upgrade from < v2.0

If you open the 1.x project, all resources such as scenes will be upgraded automatically. If there are warnings or errors in the code, you can refer to v1.10.0 Resource Upgrade Guide and the v2.0.0 Upgrade Documentation.
