Hi all,
In previous versions, I know CANVAS & WEBGL were supported to run HTML games. Since I couldn’t figure it out myself, I would like to ask if CocosCreator 2.4.2 is still supporting CANVAS html games still (instead of WEBGL)?
Thanks for your help in advance.

Hi
I have a class named MySprite which inherent Sprite and adds a bunch of properties to it.
Created a Factory class called createMySprite which calls
MySprite* theSprite = MySprite::create(“image.png”);
so I can continue to initialize theSprite.
I receive an error: *a value of type "cocos2d::Sprite * cannot be used to initialize an entity of type "MySprite "
What am I doing wrong ?

Hi
I have an empty derived Sprite class.
I addChild to it another Sprite class I created (lets call it ChildSprite).
When I create the ChildSprite object, I do childSprite->autorelease();
However as soon as the program starts, the destructor of childSprite is called and I get an assert message “Node still marked as running on node destruction! Was base class onExit() called in derived class onExit() implementations?”
If I remove the autorelease, everything works.
Any ideas why ?

Good morning, do you know if currently for cocos creator V2.2 the Facebook Live Video service works, compiling for Android?
I follow the instructions on this page
https://docs.cocos.com/creator/manual/en/sdk/fb-an-and-live.html
Entry
fb.liveStream.startLive ();
But nothing happens
The difference I see is that in the pagian it indicates that a file named
fb-live-stream.js
But it is created with the extension
fb-live-stream.jsc

What went wrong:
A problem occurred evaluating project ‘:MP’.

(I am new to Cocos2dx)
(Xcode with macOS, Android studio with Galaxy Note5)

I am making a stopwatch similar to https://cstimer.net.
The stopwatch is a cocos2d::Label* stopWatchLabel;
I am using the void update(float dt); function to update the stopwatch(Label) using the setString(); function.
It seems to work on Xcode. (Image below) (It is running)
But it doesn’t seem to work on Android Studio. As soon as I start the stopwatch, the program crashes. I think it’s because of the setString(); function. But I am not sure, and I can’t fix it.
How can I fix this code to make the stopwatch on Android?

Hi there,
I am now updating to 4.0 and have problems updating my custom commands where I would do custom drawing.
Here is an example how I accomplished this in V3 -
I would create a custom command and draw my stuff in the callback function:
AnimatedTextureRender::AnimatedTextureRender(Size s, Texture2D *texture,bool stretchTexture){
mTexture = texture;
_stretchTexture = stretchTexture;
setGLProgram(GLProgramCache::getInstance()->getGLProgram(GLProgram::SHADER_NAME_POSITION_TEXTURE));
cocos2d::Texture2D::TexParams tp1 = {GL_LINEAR, GL_LINEAR, GL_REPEAT, GL_REPEAT};
mTexture->setTexParameters(tp1);
mTexture->retain();
this->setContentSize(s);
_s = s;
autorelease();
this->scheduleUpdate();
}
void AnimatedTextureRender::draw(cocos2d::Renderer *renderer, const cocos2d::Mat4& transform, uint32_t flags){
mCustomCommand.init(_globalZOrder);
mCustomCommand.func = CC_CALLBACK_0(AnimatedTextureRender::onDraw, this, transform, flags);
renderer->addCommand(&mCustomCommand);
}
void AnimatedTextureRender::onDraw(const cocos2d::Mat4 &transform, uint32_t flags){
auto glProgram = getGLProgram();
glProgram->use();
glProgram->setUniformsForBuiltins(transform);
GL::bindTexture2D(mTexture->getName());
GL::enableVertexAttribs(GL::VERTEX_ATTRIB_FLAG_POSITION | GL::VERTEX_ATTRIB_FLAG_TEX_COORD);
glVertexAttribPointer(GLProgram::VERTEX_ATTRIB_POSITION, 2, GL_FLOAT, GL_FALSE, 0, _groundVectorData);
glVertexAttribPointer(GLProgram::VERTEX_ATTRIB_TEX_COORD, 2, GL_FLOAT, GL_FALSE, 0, _textureVectorData);
glDrawArrays(GL_TRIANGLE_STRIP, 0, (GLsizei)4);
CC_INCREMENT_GL_DRAWS(1);
}
Could anybody help me to convert this code to V4 @zhangxm, @slackmoehrle ?
I cannot really find a tutorial where this is explained in detail, looking into https://docs.cocos2d-x.org/cocos2d-x/v4/en/upgradeGuide/customCommandTutorial.html helped a bit - but was not enough for me to understand what I need to do.
Any help is appreciated

Hi
I am trying to implement zoom out of perspective camera project using the mouse wheel.
Created a new default Cocos Hello World project and added a method in HelloWorldScene called
HelloWorld::initZoomListener
{
auto listener = EventListenerMouse::create();
listener->onMouseScroll = ([](EventMouse* event)
{
auto cam = Camera::getDefaultCamera();
auto z = cam->getPositionZ();
if (event->getScrollY() > 0)
cam->setPositionZ(z + 10);
else if (event->getScrollY() < 0)
cam->setPositionZ(z - 10);
});
_eventDispatcher->addEventListenerWithSceneGraphPriority(listener, this);
}
Thats it.
I’m calling initZoomListener in the scene init method.
Now the zoom works, however if you zoom out just a little bit, everything suddendly disappearing.
Anyone knows why ?

Firstly i am so sorry for my so bad english. I am new on game developing and i try learn. I try writing a snake game, but have 2 problems for now. My first problem snake dont stable while on move and i when change the rotation,then the all body parts changing rotation but i want the part of body come to on head starting point rotation.
Some images on my problems;
My moving method;
void GameScene::snakeMove(float x,float y){
x=snakeHead->getPositionX();
y=snakeHead->getPositionY();
if(snakeHead->getRotation()==90 || snakeHead->getRotation()==270 ){
auto move = MoveBy::create(0.1f,
Vec2(-cos((snakeHead->getRotation())*M_PI / 180.0f)snakeHead->getContentSize().width/4SNAKE_BODY_SPACE,
-sin((snakeHead->getRotation())*M_PI / 180.0f)snakeHead->getContentSize().height/4SNAKE_BODY_SPACE));
snakeHead->runAction(move);
}
else {
auto move = MoveBy::create(0.1f,
Vec2(-cos((snakeHead->getRotation()+180)*M_PI / 180.0f)snakeHead->getContentSize().width/4SNAKE_BODY_SPACE,
-sin((snakeHead->getRotation()+180)*M_PI / 180.0f)snakeHead->getContentSize().height/4SNAKE_BODY_SPACE));
snakeHead->runAction(move);
}if(snakeHead->getPositionX()>(origin.x+visibleSize.width) ||snakeHead->getPositionX()<origin.x ||snakeHead->getPositionY()>(origin.y+visibleSize.height) ||snakeHead->getPositionY()<origin.y) Director::getInstance()->pushScene(TransitionFade::create(0,GameScene::createScene())); for (int i = 1; i < snakeSize; i++){ auto move = MoveTo::create(0.1f, snakeBodyParts.at(i - 1)->getPosition()); snakeBodyParts.at(i)->runAction(move); /* if(snakeBodyParts.at(i)->getPositionX()==x && snakeBodyParts.at(i)->getPositionY()==y){ auto rotate = RotateTo::create(0.1f, snakeRotation); snakeBodyParts.at(i)->runAction(rotate); }*/ //I tried this for moving rotation but not working }}

hello all,
I got stuck at very strange issue or bug. I have almost completed my game. When I played it multiple times, I found out that when I m reloading scene like retrying game then I loses a object. Each and every other object is okay. What I am doing is I stored some paths of sprites in a vector and at runtime, generating a random number in the range of vector size then picking up that path and creating a sprite with that path. Sometimes it works but sometimes it doesn’t. Each step is working (like I have paths in vector, random number is generating, it picks path from vector) but sprite is not creating (sprite is null pointer as result in this case). And this issue is same for back button, i.e. when I press back button and again press play, Sometimes it loads sprite but sometimes it doesn’t.
Can someone please help me in this.
Thanks.

I followed this document:
https://docs.cocos.com/creator/manual/en/audio/audio.html

I also attached the screenshot of AudioSource component, The sound is play but only one time, Not in loop, I want to play it in loop.

It happened after some modification in a sub-project, then this project was copied into the main project.
There is any way of know what is causing this freeze? The menu bar works, but the engine never loads.

Hi, guys. I’m trying to compile my cocos2d-x cpp project with debugging symbols, so that I can debug it with gdb on vim, as I’m not a fan of IDEs. I’m doing so with the following command: cocos compile -m debug -p linux. However, after loading the binary onto gdb (with file bin/debug/linux/projectname), I get no results when I search for those symbols. For instance, when I run info types TypeName I get nothing returned to me. Furthermore, if I search for info on a function I’ve declared (with info functions NameSpace::TypeName::funcName), the name of that function and no additional info gets listed under the “Non-debugging Symbols section”, thus suggesting these symbols aren’t being attatched to my binary when compiling.
How can I actually get those symbols? If I were to compile some program directly with g++ I’d be able to just pass the -g flag, but how can I go about doing that with the cocos tool. If I’m not able to do this using the cocos tool, how can I go about compiling my game without it and without an IDE?
