Two questions:
how to use the command “cocos framework” in command line, i put in the command like this: “cocos framework -h”, and get error response, and i can not find any info about this command anywhere
I got a cocos-js project now has only web framework, how do i creat other frameworks based on the js framework i’ve already got? see the difference between the photos, thx

I’m not an experience coder but I know that the guys who build this code were. I’ve been stuck on this for the last two days and I feel I’m missing something stupid.
Any guidance is very appreciated.
Thanks in advance

Apple no longer supports MPMoviePlayerController in iOS13 + tvOS13 causing the following error when running on xcode11:
*** Terminating app due to uncaught exception 'NSInvalidArgumentException', reason: 'MPMoviePlayerController is no longer available. Use AVPlayerViewController in AVKit.'I believe the error is associted with the cocos2dx UIVideoPlayer classes refered in the wrapper files: UIVideoPlayer-iOS.mm, UIVideoPlayer-mac.mm and UIVideoPlayer-iOS.h.
I know that @minggo from cocos 2dx dev team is working on this issue: https://github.com/cocos2d/cocos2d-x/pull/20085
- Do you know when will a version fixing this bug will be released?
- (kind of stupid question) is it ok just to replace the UIVideoPlayer files (UIVideoPlayer-iOS.mm, UIVideoPlayer-mac.mm and UIVideoPlayer-iOS.h) instead of migrating the entire project?
Thanks

Hi,
I just updated to macOS Catalina and system labels (like the ones created withcocos2d::Label::createWithSystemFont) are not showing properly.Following the code in Device-mac.mm, it looks like the bitmapData obtained from the NSBitmapImageRep has 16 bit depth rather than the 8 bit expected.
This is also happening with apps compiled on High Sierra (i.e., without recompiling them).
Can someone confirm this?

Hi Everyone,
Just FYI, some issues that occur on macOS 10.15 (Catalina) and iOS 13 have indeed been fixed in our GitHub repo.
System font label rendering issue on macOS Catalina. Corresponding issue: https://github.com/cocos2d/cocos2d-x/issues/20076

Hi all. Once I bought 14 apps with cocos framework, but don’t know cocos technology and I have to migrate them to 64bit versions, according to google play requirements. I don’t know cocos version in this apps, guess it is 2.2.6 or earlier. All apps have a libplayer.so lib only for 32bit processors, I think this lib is created when project is builded by cocos script through command line, but I don’t know how to add 64bit support. Any help is welcome =) Image may be NSFW.

I noticed that when doing a frame capture on Xcode that there were repeated setting of the viewport, winding mode, scissor rect, etc. that would customarily be done once, at the very start of the render. This appears to come from
Renderer::beginRenderPass():void Renderer::beginRenderPass(RenderCommand* cmd) { _commandBuffer->beginRenderPass(_renderPassDescriptor); _commandBuffer->setViewport(_viewport.x, _viewport.y, _viewport.w, _viewport.h); _commandBuffer->setCullMode(_cullMode); _commandBuffer->setWinding(_winding); _commandBuffer->setScissorRect(_scissorState.isEnabled, _scissorState.rect.x, _scissorState.rect.y, _scissorState.rect.width, _scissorState.rect.height); setRenderPipeline(cmd->getPipelineDescriptor(), _renderPassDescriptor); _commandBuffer->setStencilReferenceValue(_stencilRef); }Is it possible that we can remove these unnecessary calls from that method and put them somewhere else? I would imagine they are not required in OpenGL either?
What do people think?

Hi, i am using dragonbones to make skeletal animations. I’ve imported the swordsman data into my cocos proyect and now, i want to make that the attack animation generates collisions with another game character.
I have created a bounding box in dragonbones and I have created a phyisic polygon body with box2d, i linked the CCarmatureDisplay object as a userdata and i’ve got move my armature in my physics world applying forces and gravity. The problem is that i also need that the body be moved with the animacion so when the swordsman attack, its hits can generate a collision with another physic body.
I have used the body->SetTransform() metod but the bodies don’t collide, that’s because the body is frecuently updating its coordinates and when the collision occurs it tries to react according to but the position is inmediatly updated.
I need some idea, about how can i detect collisions from an skeletal animation made with dragonbones, i need it for a dynamic fighting game.

It seems the mandatory use of
cmakein the upcoming v4 branch has come as something of a shock to some users and I have spent some time recently customizing the cmake process to my own liking. I was asked by @zhangxm to create a pull request for these changes, which I have now done, and I have also added to the existing cmake documentation (seecmake/README.md) to provide insights on how to specify common customizations.I am certain there is more to say, not just about Xcode, but about all the IDEs used, as they can all be customized in similar ways. I hope that other users will contribute in this area with their own changes and tips in order to make using cmake the success I am certain it will be.
I would also be interested in anyone’s opinion on this change.

Hello friends…
i would like to print a variable value into console, but it is not doing…void init(){ //... all default events and expressions... this->scheduleUpdate(); } void update(float dt){ log("A"); //this prints fine... log(myVar); //this prints nothing }myVar is a float declared on header…
I have tried with std::cout too with no result… is there any other way to print variables?
Thanks!
