Tween - Detect elapsed time
@hananht wrote:
Is there a way to detect the elapsed time of a tween?
tween.to(10, { scale: scaleTo }, { easing: function (progress) { // elapsed time or time passed??? // duration??? return progress; }, progress: function (from, to, current, progress) { // elapsed time or time passed??? // duration??? return progress; } });This is really important parameter and I really need it. Currently I am calculating elapsed time from outside the easing function and it is not the best solution for me.

Remove custom texture from memory
@kerryk wrote:
When i create a sprite using a custom texture (not a filename) as follows
auto rt = RenderTexture::create(cutZone->getContentSize().width,cutZone->getContentSize().height,Texture2D::PixelFormat::RGBA8888); rt->beginWithClear(0, 0, 0, 0); toBeClipped->visit(); cutZone->setBlendFunc(BlendFunc{GL_ONE_MINUS_DST_ALPHA, GL_SRC_ALPHA}); cutZone->setFlippedY(true); cutZone->visit(); rt->end(); Sprite *s = Sprite::createWithTexture(rt->getSprite()->getTexture());i noticed that the texture is added in memory with a wierd key called “cc_2x2_white_image”.
When i try to free unused memory, using: Director::getInstance()–>getTextureCache()->emoveUnusedTextures(); i believe that the memory from this custom textures is not freed. Printing info about this prints:
“/cc_2x2_white_image” rc=926 id=2 2 x 2 @ 32 bpp => 0 KB
Also what happens if i add 10 custom textures in sprites (which i do), are they managed by the same key?
Can somebody from cocos team explain me memory management works in these cases and how i can free it up? @zhangxm

Proper way to pause/resume effects and BGM simple audio engine iOS
@Donmizzi wrote:
Hi, I would like to ask you how manage pause and resume effects and BGM in background/foreground with Simple Audio Engine (Cocos2dx 3.17)
Now I was working to iOS but also the solution for Android interests me for the near future
In the default code of AppDelegate.cpp od TestCpp I found this:
void AppDelegate::applicationDidEnterBackground() { Director::getInstance()->stopAnimation(); #if USE_AUDIO_ENGINE AudioEngine::pauseAll(); #elif USE_SIMPLE_AUDIO_ENGINE SimpleAudioEngine::getInstance()->pauseBackgroundMusic(); SimpleAudioEngine::getInstance()->pauseAllEffects(); #endif } // this function will be called when the app is active again void AppDelegate::applicationWillEnterForeground() { Director::getInstance()->startAnimation(); #if USE_AUDIO_ENGINE AudioEngine::resumeAll(); #elif USE_SIMPLE_AUDIO_ENGINE SimpleAudioEngine::getInstance()->resumeBackgroundMusic(); SimpleAudioEngine::getInstance()->resumeAllEffects(); #endif }With this code I have a problem with background/foreground
At the first background/foreground audio effects don’t resume (but they are queued (??))
At the second background/foreground they start, but after a while start also those that was queued in the previous “session”In some post of 2014 someone suggested to comment pause/resume BGM
Infact this solutions works, and iOS automatically pause and resume BGMI continue to try and I test that I can comment also pause/resume of audio effects (almost on iOS)
So I’m cunfused, what is the proper way to manage effects and BGM during background/foreground in iOS??
Maybe the correct way is different from remove pause/resume of BGM?
Otherwise, I don’t undestand because cocos2d-x continue to use bad code after years and yearsWhy in the default code there are the pause and resume of effects and BGM, but does the system work even without it?
They are needed for some special cases that I haven’t tested?I remember that I’m talking about iOS 8 or above
Thank you

Some issues with EditBox (Return event, setFocus)
@Orlan wrote:
Hi there,
While building an app with Cocos Creator v1.10.2, I came across several issues with the EditBox, and I hope you can help me with that.
For some reason, the EditingReturned event I set doesn’t trigger on android phones. It is working fine on iOS phones and in the simulator.
I want to set the focus on the EditBox by tapping on a button. I tried to use the setFocus() method from the EditBox API, however, it doesn’t work.
It appears to me that when an EditBox is focused, other UI elements like buttons are deactivated.
So when I just entered something via the virtual keyboard, and I press a button while the keyboard is still open, the button is not considered pressed but only the virtual keyboard disappears. Is there a solution that both of that happens within one tap?Best regards

Override vertical layout for one of the child node
@chololunaria wrote:
I have a container node with vertical layout (top-bottom). With lots of stacked nodes in it aligned perfectly vertically. And it is scrolling just like a normal chat app.
I would like to add an animation node to that container but not be shown on the bottom and I would like it to follow the positions (x, y) that I set. But this does not happen. The animation node goes to the bottom. I need it to be on top of all the child nodes of the container node.
Is there a way to achieve this?
Thanks!

About RefPtr Cast Avoidance Modification
@m_yukio wrote:
Hi,
My name is Yukio Murakai (m-yukio).Commits on Jun 26, 2016 “Improve RefPtr to avoid casting when possible”,
changed the type of _ptr from Ref to a pointer of T,
T is forward declaration (incomplete type),
If called by an inline function defined in a header file, a build error will occur.The error is the following code:
const_cast<Ref*>(static_cast<const Ref*>(ptr))->release(); static_assert(std::is_base_of<Ref, typename std::remove_const<T>::type>::value, "T must be derived from Ref");I understand the reason for reducing the cast, but
Since RefPtr is a class that manages instances of Ref, the previous implementation seems to be straightforward.

Getting current SpriteAtlas
@dsrf wrote:
Hello.
Is there any way to get the current Sprite atlas in script?
I would like to set the atlas in the editor, then animate by code.
But I don’t see any property/method to get the atlas.I only know how to do it using cc.loader and adding a custom SpriteAtlas property like so:
atlas:{ default: null, type: cc.SpriteAtlas }Setting the atlas in the editor, the cc.loader is not a solution.
Also, adding a custom property in the script means making two redundant assignments instead of one.
Something like
var atlas = this.getAtlas()
and then use getSpriteFrame would be great.
Any alternative is welcome.Thank you.
