不是帧事件回调，是没知道添加龙骨动画帧事件的地方
实在flash里边，还是在哪里加入呢？

static const auto DEFAULT_NAME = ""; creates a char* not a std::string. As result the address of a stack variable is returned. Simple fix, force the static instance to be a std::string - see diff below.

为什么是先remove，然后再add到最顶层，而不是直接slot->addDisplayToContainer(_display, i);

如题

DBCPP 现在lua事件回调直接将参数列表作为回调函数的参数列表，这样的缺点是想要增加参数就需要再向参数列表末尾添加，会打乱参数的优先级，比如后面要添加Armature的参数就要放到最后，但是这是一个重要参数。

-- @param db.DBCCArmatureNode armatureNode
-- @param int movementType
-- @param string movementId
-- @param bool isLastMovementId
local function onMovementEvent( armatureNode, movementType, movementID, isLastMovementId)

end
-- @param db.DBCCArmatureNode armatureNode
-- @param int movementType
-- @param string movementId
-- @param string frameLabel
local function onFrameEvent( armatureNode, movementType, movementID, frameLabel )

end
armatureNode:registerMovementEventHandler(onMovementEvent)
armatureNode:registerFrameEventHandler(onFrameEvent)

修改参数形式，将所有参数封装到一个table中，那么后续添加参数会很方便，也不影响现有的代码。

-- @param table event
--  db.DBCCArmature armature
--  db.DBCCArmatureNode armatureNode
--  int type
--  string boneName
--  string movementId
--  string frameLabel
--  bool isLastMovementId
local function onEvent( event )

end
armatureNode:registerMovementEventHandler(onEvent)
armatureNode:registerFrameEventHandler(onEvent)

大家看这个table 中属性名是否需要修改，如果不修改过段时间我会提交上去。

添加自动测试，以保证pr的代码不会有问题，至少是编译时错误。

When I run demo project with cocos2d-x 2.2.3, I got crash at CCTextureAtlas.cpp line 619:

        glBufferData(GL_ARRAY_BUFFER, sizeof(m_pQuads[0]) * (n-start), NULL, GL_DYNAMIC_DRAW);
        void *buf = glMapBuffer(GL_ARRAY_BUFFER, GL_WRITE_ONLY);
        memcpy(buf, m_pQuads, sizeof(m_pQuads[0])* (n-start));
        glUnmapBuffer(GL_ARRAY_BUFFER);

It's called by m_pTextureAtlas->drawNumberOfQuads(1, m_nQuadIndex);

Is this the bug of DragonBoneCpp or cocos2d-x?

看了下代码，似乎还不支持变色的所有参数 alphaOffset redMultiplier 等等，只是从xml中读出来了。需要添加shader处理吗？

如题
是DBCCSlot::updateDisplayBlendMode函数里的 if (_childArmature) 条件放在 if (spriteDisplay) 条件里的原因吧？
我们自己的程序，把判断移出来之后blendfunc变为正常，但是我现在无法确定这个是bug还是因为特殊的设定。

Hi!, I'm trying to compile the Cocos2dx 3.0 demo that comes with this library to make it work in Android (DragonBonesCPP-dev\demos\cocos2d-x-3.x\DragonBonesCppDemos)
But I'm getting trouble making it work. Specially because there are not android-mk files in the renderer/cocos2dx3.0 folder. I tried to make it myself but I can't get the include files right.

Is there any working test sample for using Cocos2dx 3.0 with DragonBones?

Im using Eclipse and windows 7.

Thanks in Advance, Really great library!!

在optimization临时分支中，初步做了修改：

1. 在xxxData.h等结构文件中的 getXXX()方法增加判空，减少空值的循环遍历，如BaseDataParser::setFrameTransform中getBoneData的操作，由于没有判空条件，一旦动画层数过多时这里的消耗还是比较可观的；
2. 考虑去掉hideTimelineList结构，在解析过程中不做addHideTimeline的调用，在AnimationState::hideBones()方法中通过getBones和getTimeline来结合进行hideSlots，减少遍历次数；
3. 考虑将部分查找频繁过遍历的结构改成map的形式？

DragonBonesCPP seems to have cloned code from SkeletonAnimationLibraryCPP. Is it intended to replace SkeletonAnimationLibraryCPP? Thanks.

调用代码
local bone=self.body:getCCSlot("Layer_11")
self.gy=db.buildArmatureNode("zf")
self:add(self.gy)
bone:setChildArmature(self.gy:getArmature())
self.gy:pos(100,100)
self.gy:getAnimation():gotoAndPlay("stand", -1, -1, 0)

出错位置
DBCCArmatureNode::~DBCCArmatureNode()
{

if (DRAGON_BONES_ENABLE_LUA == 1)

unregisterFrameEventHandler();
unregisterMovementEventHandler();

endif // DRAGON_BONES_ENABLE_LUA

if (_clock)
{
    _clock->remove(this);
    _clock = nullptr;
}

if (_armature)
{
    delete _armature;//《-----------------------崩溃后调试armature已经被释放掉了
    _armature = nullptr;
}

}

是我的用法有问题么？

Previous version breaks on Visual Studio while firing up in debug mode.

The warning is: HEAP: Free Heap block XXXX modified at XXXX after it was freed

But latest version crashes anyway.

The error is: In CCRef the reference count is none zero while freeing the pointer. And in AmatureDisplayContainer.cpp line 42, before the EventDispatcher pointer is released, the address is already 0xfeeefeee.

Please solve the bug! It's fatal!

好像龙骨动画的性能并不高，我们测试官方的小绿龙，在iPad3上同时跑100个，帧数掉到了25帧左右，这是完全无法接受的。

不知道是动画本身复杂度的问题，还是播放框架的问题？动画制作的过程中，有没有什么需要注意的地方，可以提高性能的？代码上有没有什么缓存或者其他方式可以提高性能？

Hi.

I am using cocos2d-x 3.2 and DragonBonesCPP dev branch.
The DragonBonesHeaders.h includes CCDragonBones.h This file only exist in renderer\cocos2d-x-2.x and not in renderer\cocos2d-x-3.x.

https://github.com/DragonBones/DragonBonesCPP/wiki/Manage-a-git-library-with-submodules

Error : Expression: vector subscript out of range
On : BaseTimelineState.h line 277
const auto currentFrame = _timeline->frames[currentFrameIndex];

_timeline->bone is NULL ? and _timeline->frames have zero frame inside ?
at passed time == 0.0f it still working but when passed time insert from 0.0f to 0.xxxf ( on the first time ) it cause that error.

my implement :
dragonBones::CCFactory _factory;
_factory.loadDragonBonesData(_refInfo->armaturePath);
_factory.loadTextureAtlasData(_refInfo->armatureTexture);
_armature = _factory.buildArmatureDisplay(_refInfo->armatureName, _refInfo->armatureDataName);
_armature->getAnimation().fadeIn(_refInfo->armatureAnimationIdie);
i ran on cocos2d-x 3.8
happen with any dragonbones file at Demo folder.

I would like to point out that identifiers like "__ARMATURE_H__" and "__BONE_H__" do not fit to the expected naming convention of the C++ language standard.
Would you like to adjust your selection for unique names?

TimelineState::update裡面
if(progress == 1)
{
progress = 0.99999999f;
}

0.99999999f 趨近於 1
0.99999997f 趨近於 0.99999994f

cocos2dx 中 getBoundingBox 返回flash中 getBounds(parent) 的值

现在DBCCArmatureNode::getBoundingBox 返回flash中 getBounds(null) 的值

使用 getInnerBoundingBox 来返回 flash中 getBounds(null)
getBoundingBox还是按照cocos2dx中的规则来返回flash中 getBounds(parent)

使用最新的3.9framework生成的lua_dragonbones_auto.cpp中的getDragonBonesDataMap()方法报错。看本官方DragonbonesCPPForLua中没这个方法，该怎么处理？dragonbones.ini中删了这方法？

The main file : BinaryParser

it would be great if dragonbones support flatbuffers for small file size.

I suggest to change name of the directory /library to /dragon-bones.

1. The most straightforward motivation is for Android's Makefile, which needs to import the library by the name of directory which contains the library's Android.mk. So, currently the line in Android.mk to import the DragonBones library will look like this:

   $(call import-module, library)

   which is very confusing. Moreover, if more than one project follow such naming convention, there will be name conflicts when an application needs to import libraries from all of them. Although we can "solve" the problem by adding the parent directory of DragonBonesCPP to NDK_MODULE_PATH and use DragonBonesCPP/library for import-module, but that will restrict the user renaming the top level directory DragonBonesCPP, which makes no sense.

2. Such renaming is also consistent with other projects. For example, in cocos2d-x the main source code directory is /cocos2dx. To import cocos2dx library in Android.mk, the line will look like this:

   $(call import-module, cocos2dx)

Thanks!

是否能够提供一个结构可以跳转到某动画的指定帧播放?

In c965e99 the sample looks like this:

Since 4961178:

This also breaks Ubbie and virtually any armature:

I also tried exporting the data again with 4.7.3 - looks exactly the same.

Hi there!
Excuse me! Can you show me how to detect collision by Box2D physics or how to use function boundingbox() to detect collision.
i saw that coordinate of the Armature and the ArmatureNode are not same. So, we need to convert it to same coordinate, is it right?
Why don't we intergration the Box2D lib into Armature to use it?
Sorry. I'm not good at English
dear.

我加了12个角色（总共5个不同的角色），魅族mx3上的帧数只有10帧左右，touch4是40帧左右，用的版本是quick2.2.5

has someone can merge this? #110

需要改的地方非常多，官方有升级计划吗？

DragonBonesCpp现在有支持4.0以上版本制作的龙骨文件解析吗

目录结构类似这样，那么只需要将dragonbones目录放到editor-support文件下就OK了。不需要再单独放renderer。

动画师那里用flash 做完，用一个插件导出 http://dragonbones.effecthub.com/
导出之后发现blendMode这个字段就没有了。是因为这个插件的问题嘛？
请问，你们有推荐的插件嘛？

当前的例子是把图片打包到texture.png里面。这样换装不符合项目实际需要。
比如一个换装游戏，几百上千的衣服，裤子。这种情况肯定衣服都是一张一张的外部图片。

我想請教一下 我們在使用flash編輯動畫時 發生了同一個動作 在第二次播放後 元件沒有改回原本顏色狀態

我的推測是 當我在 TimelineState::updateToNextFrame 這個函式下

由於第二次播放元件時 該bone的_isColorChanged == false 所以沒有還原上次造成的效果

我們設計的案例是這樣的 有一個timeline 內有3條補間動畫影格 其中第1條是一個image 第二第三條是另一個image

不過在第三條 我們改變了color transform

我有想出一個方法解決 就是無視上述 _isColorChanged 的判斷 只要一切換就將bone的顏色還原

但不知道這樣做會不會影響舊有系統?
