What’s new
New platforms always mean new opportunities and challenges. Cocos Creator 2.4.1 adds support for two new platforms: HUAWEI AppGallery Connect and lianshang games. You can now choose these platforms when building. This version allows your game to connect to Huawei HMS Core with one click, and upload to HUAWEI AppGallery with one click Connect, eliminating the complicated operations such as accessing SDKs and uploading platforms during the development process, helping developers create high-quality innovative applications and enhance the game experience!
Added HUAWEI AppGallery Connect release platform
In Cocos Creator, through the HUAWEI AppGallery Connect publishing platform, developers can access Huawei HMS Core with one click, including login, payment, Share, Location, Analysis and other services that can greatly improve the developer’s work efficiency.
Developers can enable the SDKHub in the service panel and configure the corresponding SDK presets.
Choose HUAWEI AppGallery Connect platform during building, and select the preset SDK preset.
After the building is completed, you can upload with one click through the upload window.
Added LianShang game publishing platform
LianShang Mini Games is a mini game application platform under the WiFi Master Key, which is convenient, lightweight, and free of installation. It is now officially supported by Cocos Creator. Developers only need to select the Lianshang Mini Games release platform when building, and the platform adaptation is automatically completed.
For more information about publishing to LianShang Mini Games, please refer to the Publishing documentation.

Known issues
- After the iOS device is upgraded to iOS 14 beta.2, there will be a problem that the web platform cannot display the screen temporarily. You can customize the engine and merge the changes manually [#6974] to resolve. We will continue to follow up with subsequent versions of iOS 14 to avoid compatibility issues.
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.loaderis no longer recommended, please use the latestcc.assetManagerinstead, 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.RawAssetthat was deprecated since 1.10 has been officially removed, please usecc.Assetinstead. 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.fromHexis deprecated, please usecc.Color.fromHEXinterface
Upgrade from < 2.3.3 version
-
The
CCTexture2DandCCTexture2DRGBmethods in the Effect have been abandoned. -
Vec3.FRONThas been abandoned, please useVec3.FORWARDinstead.
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/srcdirectory, and the third-party library used by itself, please put it in theapp/libsdirectory. -
If the code and third-party libraries used by Android Instant are separate, please put them in the
game/src,game/libsdirectories. -
For code and third-party libraries shared by Android and Android Instant, please place them in the
srcandlibsdirectories under theproj.android-studioroot directory, respectively. -
proj.android-studiounder the root directoryjni/CocosAndroid.mk,jni/CocosApplication.mk, mainly used to configure engine-related configuration, developer configuration, it is recommended that Android be placed inapp/jni/Android.mkandapp/jni/Application.mk, Android Instant, please put ingame/jni/Android.mkandgame/jni/Application.mk. -
When Cocos Creator compiles for Android, it will execute
assembleRelease/Debugby default, and when compiling for Android Instant, it will executeinstant: 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.
