Hey all
I’ve encountered the following issue when debugging my game on Android with the Emulator.
I get a black screen while the application actually running but nothing is displayed on screen. Funny thing, I do manage to see ads - interstitials.

And it keeps going like that.
I found a topic that says this error (OpenGL error 0x0502) has been solved in cocos2dx 3.17 (Android emulator black screen), but I’m using 3.17.2 with PROP_APP_ABI=armeabi-v7a:arm64-v8a:x86 and still get this issue for some reason.
Found a doc (https://drive.google.com/file/d/1ChY7c1xSnKmu_vTuEoseshHBzvivlVqB/view) that suggests to edit CCGLProgram.cpp, I did tried that but the issue still persists.

One thing to note is that the first error on the log is actually:

E/eglCodecCommon: removeVertexArrayObject: ERROR: cannot delete VAO 0!

And then we get to see the OpenGL error 0x0502 error in CCRenderer.cpp and CCTextureAtlas.cpp
Is this a new face of an old problem?

Hi folks!
I’m trying to make a screenshot share feature for my little 3d game made with Cocos Creator 2.3.3.
I’ve already implemented the feature and it works well on 2d objects but something weird happends on 3d setup.
How it works:
I create a render texture is onLoad function (inspired from 07_capture_texture in the example cases project)

this.Render_Texture = new cc.RenderTexture();
this.Render_Texture.initWithSize(cc.visibleRect.width, cc.visibleRect.height, RB_FMT_S8);

When user hit screenshot I change camera’s targetTexture for one frame:

this.Camera.targetTexture = this.Render_Texture; // let the camera to render one frame on the texture
this.scheduleOnce(function(){ 
    this.Capture_Screen_And_Share();
    this.Camera.targetTexture = null; // remove render target
}.bind(this),0);

This is the result. Only the last objects in node tree are visible:

I’ve changed render texture buffer format:

this.Render_Texture.initWithSize(cc.visibleRect.width, cc.visibleRect.height, cc.gfx.RB_FMT_D16);

This is the 2nd result:

Crowded_Streets_20204101013351280×720 118 KB

As you can see this is much better but we have jagged edges on some objects. I think there is a depth buffer resolution problem.

This is the real screenshot of the game. I’m trying to get this result:

What’s New

Support PCF soft shadow

Starting from v2.3.3, the Light component can set the shadow type to SOFT_PCF3X3 or SOFT_PCF5X5 to turn on soft shadows. After opening, the shadow will not have hard edges, the effect is more soft and natural. Example:

1385×708 16.5 KB

Support zooming Sprite by 9-sliced SpriteFrame in TILED mode

Starting with v2.3.3, the image will be repeated to fit the size of the Sprite when using TILED mode. If the SpriteFrame is 9-sliced, the corners will also remain unscaled while the other areas will be repeated.

Improve web page loading speed during preview

In order to further improve development efficiency, we optimized the loading speed of scripts during web page preview in both the engine and in project code. When the custom engine feature is turned on, or when using a mobile phone to preview, developers get a really smoother experience.

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 < 2.3.3 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.

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.

Just in case

Note: If you prefer not to use Dashboard now, you may still download Cocos Creator v2.3.3 for MacOS and Windows. However, starting with Cocos Creator v2.4 using Dashboard will be required! There will no longer be a separate Cocos Creator installer provided. Please download and get acclimated with Dashboard soon.

Hello,
So we have a Android social chat app sort of . And we are looking to add some js games like from cocos creator to the app to be played.

We want to add several games.
So should we like use Webview to open those js games?
is there some faster and more performant way for it.

Hi, we missing only a step to complete our project… the IAP.
So we could use sdkbox to integrate it, but we don’t know how sdkbox works on cococreator.

1. where is the sdkbox_config.json file?
2. we have wrote this file to use sdkbox, maybe rights?

I find the Cocos creator particle system difficult to use. The following 3 things make me feel very annoying and I think these are bugs:

1. The particle speed is not stable, sometimes very slow and sometimes very fast even though I have set the speed to 0.

2. The particle’s color is not accurate, although I set it all to white (alpha: 255 for both start and end). But in the game the color is completely random.

3. The color blend is hard to use, the effect displayed on the Editor is completely different on the web browser. Moreover, none of the settings render what I want. I just wanted it to display correctly, but completely failed.

• If DST_ALPHA, the color is almost white.
• If ONE_MINUS_SRC_ALPHA, I have attached the following picture.
• For the remaining settings it draws tranparency to black or a random color. I do not understand their purpose to do?

This is the original image and I want it to display exactly like this:

Here is the actual image:

I can’t seem to get debugging working quite right, no matter what I try. Half the time I’m going off outdated articles translated from Chinese, as there’s so little official documentation available on IDE setup (at least that I can see). Getting a little frustrated and would really appreciate some help.

I’m frequently getting this page when I try to resume the script:

Sometimes WebStorm hangs for several minutes before launching the browser, and then usually gets stuck on the loading bar.

I’m also not able to step-into cocos library functions, although I had this working temporarily and must have broken it while trying to fix another issues.

I’d be very grateful for any up-to-date steps on settings things up correctly, thanks!

Hi, I’m using cocos creator for developing android app, My app is about to finished but I’m stuck at the hot update thing, I read the documentation(a bit, and still didn’t understand how it works) and I downloaded the sample provided, the sample’s project is older than my current cocos creator version, 2.1.4.

I tried to run the sample’s project anyway and tried to use the Update button, but none of them are working because it local manifest doesn’t found(but there’s “project” manifest on asset folder and in the canvas, there’s Hot update script where the ManifestUrl is already assigned to project manifest)

can someone please help ? I’m confused how hot-update in this project works since there are md5 thing, and i’ve seen inside the project.manifest, what is packageUrl, is this the package we’re gonna download ? also what is Manifest for? I thought update is like just download a specific file then replacing the specific file at specific location/path.
