  1. 从Spine官方下载3.8.95版本的spine-cpp、spine-cocos2dx；
  2. 删除cocos2d-x/cocos/editor-support/spine中所有的旧版本的spine代码；
  3. 把spine-cpp、spine-cocos2dx所有源文件全部拷贝到cocos2d-x/cocos/editor-support/spine目录；

一、Lua-binding

1、使用如下配置完全覆盖掉之前的cocos2dx_spine.ini

[cocos2dx_spine]
# the prefix to be added to the generated functions. You might or might not use this in your own
# templates
prefix = cocos2dx_spine

# create a target namespace (in javascript, this would create some code like the equiv. to `ns = ns || {}`)
# all classes will be embedded in that namespace

# what headers to parse

rename_classes = SkeletonRenderer::Skeleton

# Determining whether to use script object(js object) to control the lifecycle of native(cpp) object or the other way around. Supported values are 'yes' or 'no'.
script_control_cpp = no

2、修改conversions.yaml

由于使用了spine-cpp版本，spine加了很多基础数据类型，在自动绑定lua时，需要定义类型转换代码

conversions：

    ...
    
    to_native:
        
        ...
        
        "String": "ok &= luaval_to_spine_string(tolua_S, ${arg_idx},&${out_value}, \"${lua_namespaced_class_name}:${func_name}\")"
        size_t: "ok &= luaval_to_size_t(tolua_S, ${arg_idx}, &${out_value}, \"${lua_namespaced_class_name}:${func_name}\")"
    
        object: ...
    
    from_native：
        
        ...
        
        # "@Vector<.*>": "ccvector_to_luaval(tolua_S, ${in_value})"
        "@Vector<(?!spine::).*>": "ccvector_to_luaval(tolua_S, ${in_value})"
        
        ...
        
        "String": "lua_pushlstring(tolua_S,${in_value}.buffer(),${in_value}.length())"
        "Color": "spine_color_to_luaval(tolua_S, ${in_value})"
        "@(?:\\bBoneData\\b|\\bSkeleton\\b|\\bColor\\b|\\bEventData\\b|\\bIkConstraintData\\b|\\bPathConstraintData\\b|\\bTransformConstraintData\\b|\\bBone\\b|\\bSlotData\\b)+(?!\\*)+":  "object_to_luaval<${ntype.replace('const ', '').replace('&', '')}>(tolua_S, \"${scriptname}\", (${ntype.replace('const ', '').replace('&', '')}*)&${in_value})"
        "@Vector<spine::((?!String).)*>": "spine_vector_ptr_to_luaval(tolua_S, ${in_value})"
        "@Vector<int.*>": "spine_vector_int_to_luaval(tolua_S, ${in_value})"
        "@Vector<unsigned int.*>": "spine_vector_uint_to_luaval(tolua_S, ${in_value})"
        "@Vector<short.*>": "spine_vector_short_to_luaval(tolua_S, ${in_value})"
        "@Vector<unsigned short.*>": "spine_vector_ushort_to_luaval(tolua_S, ${in_value})"
        "@Vector<float.*>": "spine_vector_float_to_luaval(tolua_S, ${in_value})"
        "@Vector<spine::String.*>": "spine_vector_spine_string_to_luaval(tolua_S, ${in_value})"
        size_t: "tolua_pushnumber(tolua_S,(lua_Number)${in_value})"
        
        object: ...

3、定义类型转换方法

在cocos2d-x/cocos/scripting/lua-bindings/manual/下增加SpineConversions.h、SpineConversions.cpp

// SpineConversions.h
#pragma once

    if (nullptr == L)
        return;

    int indexTable = 1;
    spine::Vector<T> tmpv = inValue;
    for (size_t i = 0, count = (size_t)tmpv.size(); i < count; i++)
    {
        std::string typeName = typeid(tmpv[i]).name();
        auto iter = g_luaType.find(typeName);

        return;

    lua_newtable(L);

    spine::Vector<unsigned int> tmpv = inValue;
    for (size_t i = 0, count = (size_t)tmpv.size(); i < count; i++)
    {

        lua_pushstring(L, tmpv[i].buffer());
        lua_rawset(L, -3);
    }
}

4、自动导入SpineConversions.h

修改cocos2d-x/tools/bindings-generator/targets/lua/templates/layout_head.c，自动导入SpineConversion.h

...

\#include "scripting/lua-bindings/manual/tolua_fix.h"
\#include "scripting/lua-bindings/manual/LuaBasicConversions.h"
\#include "scripting/lua-bindings/manual/SpineConversions.h"

...

5、适配Skeleton的创建接口

由于Spine 3.8.95增加了二进制文件格式，因此Cocos2dx的适配层LuaSkeletonAnimation需要做如下修改：

// scripting/lua-bindings/manual/LuaSkeletonAnimation.cpp
LuaSkeletonAnimation* LuaSkeletonAnimation::createWithFile(const std::string& skeletonFilepath, Atlas* atlas, float scale) {
    LuaSkeletonAnimation* node = new LuaSkeletonAnimation();
    if (FileUtils::getInstance()->getFileExtension(skeletonFilepath) == ".json") {
        node->initWithJsonFile(skeletonFilepath, atlas, scale);
    }
    else {
        node->initWithBinaryFile(skeletonFilepath, atlas, scale);
    }
    node->autorelease();
    return node;
}

LuaSkeletonAnimation* LuaSkeletonAnimation::createWithFile(const std::string& skeletonFilepath, const std::string& atlasFile, float scale) {
    LuaSkeletonAnimation* node = new LuaSkeletonAnimation();
    if (FileUtils::getInstance()->getFileExtension(skeletonFilepath) == ".json") {
        node->initWithJsonFile(skeletonFilepath, atlasFile, scale);
    }
    else {
        node->initWithBinaryFile(skeletonFilepath, atlasFile, scale);
    }
    node->autorelease();
    return node;
}

二、Win32

用VS2017打开项目工程，移除所有的旧的Spine代码引用，再把新的Spine代码引入进来，重新编译。

三、IOS

类似Win32，唯一区别是把VS2017换成Xcode

四、Android平台

Android需要改动到Android.mk(如果使用NDK进行编译)或CMakeList.txt(如果使用CMake)，以下以NDK编译示例

1，Spine库的Android.mk

Spine库的Android.mk在目录cocos2d-x/cocos/editor-support/spine/Android.mk，使用以下代码覆盖掉之前的。

LOCAL_PATH := $(call my-dir)
include $(CLEAR_VARS)

LOCAL_MODULE := spine_static

LOCAL_MODULE_FILENAME := libspine

LOCAL_EXPORT_C_INCLUDES := $(LOCAL_PATH)/..

LOCAL_C_INCLUDES := $(LOCAL_PATH)/..

LOCAL_STATIC_LIBRARIES := cocos2dx_internal_static

include $(BUILD_STATIC_LIBRARY)

2，luacocos2d库的Android.mk

把SpineConversions放入luacocos2d库中

...

LOCAL_SRC_FILES += ../manual/spine/lua_cocos2dx_spine_manual.cpp \
                   ../manual/spine/LuaSkeletonAnimation.cpp \
                   ../manual/SpineConversions.cpp \
                   ../auto/lua_cocos2dx_spine_auto.cpp

...

五、实现挂点

实现Spine挂点，有两种方案：

  1. Creator的实现方案：根据骨骼层次生成节点树，在Spine每次render时更新节点树的世界矩阵；
  2. 不创建节点树，在Spine每次transform后，同步更新需要挂载的节点；

对于方案一，在Cocos2d-x中较难实现，主要是在矩阵转换上比较麻烦，而且对引擎侵入性较大，对于此方案，目前没有找到比较好的解决方法。

采用方案二简单实现挂点

1，定义PostUpdateWorldTransforms事件

// cocos2d-x/cocos/editor-support/spine/AnimationState.h
enum EventType {
    ...
    
    EventType_PostUpdate,
};

// cocos2d-x/cocos/scripting/lua-bindings/manual/cocos2d/LuaScriptHandlerMgr.h
enum class HandlerType: int
{
    ...
    
    EVENT_SPINE_ANIMATION_POST_UPDATE
}


// cocos/spine/SpineConstants.lua
sp.EventType =
{
    ...
    
    ANIMATION_POST_UPDATE = 6,
}

2，手动绑定监听

//  cocos2d-x/cocos/scripting/lua-bindings/manual/spine/lua_cocos2dx_spine_manual.cpp
int tolua_Cocos2d_CCSkeletonAnimation_registerSpineEventHandler00(lua_State* tolua_S)
{
    ...
    
    switch (eventType) {
        ...
        
        case EventType::EventType_PostUpdate: {
            self->setPostUpdateWorldTransformsListener([=](SkeletonAnimation* skeletonAnimation) {
                handleSpineUpdateEvent(handler, skeletonAnimation);
            });
            ScriptHandlerMgr::getInstance()->addObjectHandler((void*)self, handler, ScriptHandlerMgr::HandlerType::EVENT_SPINE_ANIMATION_POST_UPDATE);
            break;
        }
    }
}

int tolua_Cocos2d_CCSkeletonAnimation_unregisterSpineEventHandler00(lua_State* tolua_S)
{
    ...
    
    switch (eventType) {
        ...
        
        case EventType::EventType_PostUpdate: {
            handlerType = ScriptHandlerMgr::HandlerType::EVENT_SPINE_ANIMATION_POST_UPDATE;
            break;
        }
    }
}

增加回调处理方法

static int handleSpineUpdateEvent(int handler, spine::SkeletonAnimation* skeletonAnimation)
{
    LuaStack* stack = LuaEngine::getInstance()->getLuaStack();

    stack->pushObject(skeletonAnimation, "sp.SkeletonAnimation");

    stack->executeFunctionByHandler(handler, 1);
    stack->clean();

    return 0;
}

3，lua中调用

self.skeleton:registerSpineEventHandler(function(event)
    updateAttachedNode(self.skeleton, self.attachedBoneName, self.attachedNode)
end, sp.EventType.ANIMATION_POST_UPDATE)

function updateAttachedNode(skeleton, boneName, attachedName)
    local bone = skeleton:findBone(boneName)
    attachedNode:setPosition(cc.p(bone:getWorldX(), bone:getWorldY()))
    attachedNode:setRotation(-bone:getWorldRotationX())
    attachedNode:setScaleX(bone:getWorldScaleX())
    attachedNode:setScaleY(bone:getWorldScaleY())
    attachedNode:setVisible(bone:isActive())
end
