- 從Spine官方下載3.8.95版本的spine-cpp、spine-cocos2dx；
- 刪除cocos2d-x/cocos/editor-support/spine中所有的舊版本的spine代碼；
- 把spine-cpp、spine-cocos2dx所有源文件全部拷貝到cocos2d-x/cocos/editor-support/spine目錄；
一、Lua-binding
1、使用如下配置完全覆蓋掉之前的cocos2dx_spine.ini

# 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
由於使用了spine-cpp版本，spine加了很多基礎數據類型，在自動綁定lua時，需要定義類型轉換代碼
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})"
...

size_t: "tolua_pushnumber(tolua_S,(lua_Number)${in_value})"
object: ...
3、定義類型轉換方法

lua_pushstring(L, tmpv[i].buffer());
lua_rawset(L, -3);
}
}
4、自動導入SpineConversions.h
修改cocos2d-x/tools/bindings-generator/targets/lua/templates/layout_head.c，自動導入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、適配Skeleton的創建接口
由於Spine 3.8.95增加了二進制文件格式，因此Cocos2dx的適配層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打開項目工程，移除所有的舊的Spine代碼引用，再把新的Spine代碼引入進來，重新編譯。
三、IOS
類似Win32，唯一區別是把VS2017換成Xcode
四、Android平台
Android需要改動到Android.mk(如果使用NDK進行編譯)或CMakeList.txt(如果使用CMake)，以下以NDK編譯示例
1，Spine庫的Android.mk
Spine庫的Android.mk在目錄cocos2d-x/cocos/editor-support/spine/Android.mk，使用以下代碼覆蓋掉之前的。
LOCAL_PATH := $(call my-dir)
include $(CLEAR_VARS)
LOCAL_MODULE := spine_static
LOCAL_MODULE_FILENAME := libspine
LOCAL_ARM_MODE := arm
LOCAL_SRC_FILES := \

VertexEffect.cpp
LOCAL_EXPORT_C_INCLUDES := $(LOCAL_PATH)/..
LOCAL_C_INCLUDES := $(LOCAL_PATH)/..
LOCAL_STATIC_LIBRARIES := cocos2dx_internal_static
include $(BUILD_STATIC_LIBRARY)
2，luacocos2d庫的Android.mk
把SpineConversions放入luacocos2d庫中
...
LOCAL_SRC_FILES += ../manual/spine/lua_cocos2dx_spine_manual.cpp \
../manual/spine/LuaSkeletonAnimation.cpp \
../manual/SpineConversions.cpp \
../auto/lua_cocos2dx_spine_auto.cpp
...
五、實現掛點
實現Spine掛點，有兩種方案：
- Creator的實現方案：根據骨骼層次生成節點樹，在Spine每次render時更新節點樹的世界矩陣；
- 不創建節點樹，在Spine每次transform后，同步更新需要掛載的節點；
對於方案一，在Cocos2d-x中較難實現，主要是在矩陣轉換上比較麻煩，而且對引擎侵入性較大，對於此方案，目前沒有找到比較好的解決方法。
采用方案二簡單實現掛點
1，定義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，手動綁定監聽
// 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;
}
}
}
增加回調處理方法
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中調用
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
