Hello,
I’m currently working on a game which has to be integrated with react native. Thus, I will be using the cocos-2D-v3.13.js file as the engine.
I would have to support varied number of mobile devices and tablets. But won’t be targeting desktops.
I really need a pointer or two about multi resolution support.
I went through quite a number of posts about the same, but some of the links were dead. I have been working on corona-sdk for a while and I have clear idea about safe areas and multi-resolution support.
But my question is how do I do it in cocos-2D-js.
Are safe areas not a concern if I’m using canvas. How do I go about calling for prefixed assets such as 1x - normal sized assets. 2x - high resolution assets. 4x- retina resolution assets.
Please guide me in this regard
Thank you

I want to create multiple menu scenes. Example, Im in main menu. i want to navigate to option menu. then i want to go back to main menu. whats the best practice here?
Maybe I create main menu scene from appdelegate. then i can create option menu and call
Director::getInstance()->replaceScene(OptionsMenuScene) from MainMenuScene class. if i want to go back, i can Director::getInstance()->replaceScene(MainMenuScene). provided that optionsmenuscene and mainmenuscene is global and already created/initialized. if for example, you would have multiple levels and each levels is a scene, it would not be nice if i have to create and initialize every levels when starting the application. it would be nice if the level scene is only created when you want to use it.
also, what happens to the scene objects that is being replaced? is it gone?

Hello, I am a Korean developer.
I am making card games through TypeScript of Cocos Creator.
The problem is, I currently have to calculate the odds with my card, which takes approximately 600 ms to go through.
In the meantime, the rendering of the game is stopped.
I’m using Promise, but it’s the same.
What should I do?

On first time loading the game nodes with body component shows correct position, see the following image, box is at cc.v2(100,100) at 500x500 screen size, small red box is at cc.v2(0,0) for reference
But when I update screen size to 700x500 then box auto update it’s position to cc.v2(-28, 100)
If I reload the page again the box will start showing correct position again
seems like rigid bodies listening for screen resize event and adjust their position accordingly
Without rigidbody component this behaviour not occurs.
Anyone knows how to fix it?

Are there any tutorial on physics for recent cocos2d-x?
I find the information here incomplete : https://docs.cocos2d-x.org/cocos2d-x/v4/en/physics/collisions.html
For example, what does this line do? Where can I find the function? I assume the first parameter is position but what is the second parameter?
auto sprite = addSpriteAtPosition(s_centre, 1);
This is my custom made function for addSpriteAtPosition.
Sprite addSpriteAtPosition(Vec2 loc)
{
auto sprite = Sprite::create("CloseNormal.png");
sprite->setPosition(loc);
auto spriteBody = PhysicsBody::createCircle(sprite->getContentSize().width / 2, PhysicsMaterial(0, 1, 0));
sprite->setPhysicsBody(spriteBody);
}
How to show physics debug mode?

I’ve tried building and running a cocos2d-x 4.0 project on Linux today and encountered the ages-old error (at runtime):
cocos2d/external/linux-specific/fmod/prebuilt/64-bit/libfmod.so.6: file too short
But that’s not the point of this thread.
It seems that cocos2d-x still uses FMOD audio engine on Linux platform even in 4.0. This is not okay for the kind of license cocos2d-x uses.
FMOD is no longer a free product. It has a free (indie) license type, but even that has several serious constraints. Here’s some excerpts from FMOD’s licensing page:
“Note: Free Indie License may only be used 1 time each 12 months. Additional use in that period incurs a fee of $2,000 per game.”
“To be licensed, you must register your project and display the FMOD logo on a splash screen in your game.”
Definitely not something you want to have in a default cocos2d-x build setup on any platform.
How come this pull request was not finished and merged yet?

Hello,
I have developed a sample game in cocos-js deployed as a web version.
I have been testing the game on multiple devices and it seems to be working fine.
But when it comes to iPhoneX and few devices with notch at the top, the touch seems to be off a little to the top.
Has anyone encountered this issue.
Please reply ASAP.

Hi there!
if I understand well, i save into an int type an instance of an audio when i play it:
int bgm_main = cocos2d::AudioEngine::play2d("./bgm.ogg", true);
so i can set some properties like:
cocos2d::AudioEngine::setVolume(bgm_main, 0.7f);
but what is the way to play the same audio again?.. do i need to redo this?:
int bgm_main = cocos2d::AudioEngine::play2d("./bgm.ogg", true);
or can i usue bgm_main in other way?
Thanks
