我怎麼能借鑑的東西精靈精靈不

後面我用cocos2dx V3.8，併成功借鑑的東西與覆蓋得出這樣的：我怎麼能借鑑的東西精靈精靈不

void Box2dManager::draw(Renderer *renderer, const Mat4& transform, uint32_t flags){ 
    GL::enableVertexAttribs(GL::VERTEX_ATTRIB_FLAG_POSITION); 
    Director::getInstance()->pushMatrix(MATRIX_STACK_TYPE::MATRIX_STACK_MODELVIEW); 
    box2dWorld->DrawDebugData(); 
    Director::getInstance()->popMatrix(MATRIX_STACK_TYPE::MATRIX_STACK_MODELVIEW); 
// super::draw(renderer, transform, flags); 
}

但它總是背後的精靈。它在修改z順序後不能更改。

解決

現在我能處理的cocos2d 3.x版的Box2D DrawDebugData問題。我粘貼所有的cocos2dx解決代碼。 V2（簡單，因爲V2引擎的OpenGL平局是每個單一任務）

void Box2dManager::draw(){ 
    ccGLEnableVertexAttribs(kCCVertexAttribFlag_Position); 
    kmGLPushMatrix(); 
    box2dWorld->DrawDebugData(); 
    kmGLPopMatrix(); 
}

V3（V3引擎推動平局commond與quence核心，所以你需要創建一個回調）

void Box2dManager::draw(Renderer *renderer, const Mat4& transform, uint32_t flags){ 
    super::draw(renderer, transform, _transformUpdated); 
    GL::enableVertexAttribs(cocos2d::GL::VERTEX_ATTRIB_FLAG_POSITION); 
    Director* director = Director::getInstance(); 
    CCASSERT(nullptr != director, "Director is null when seting matrix stack"); 
    director->pushMatrix(MATRIX_STACK_TYPE::MATRIX_STACK_MODELVIEW); 
    _modelViewMV = director->getMatrix(MATRIX_STACK_TYPE::MATRIX_STACK_MODELVIEW); 
    _customCommand.init(_globalZOrder); 
    _customCommand.func = CC_CALLBACK_0(Box2dManager::onDraw, this); 
    renderer->addCommand(&_customCommand); 
    director->popMatrix(MATRIX_STACK_TYPE::MATRIX_STACK_MODELVIEW); 
} 

void Box2dManager::onDraw() { 
    Director* director = Director::getInstance(); 
    CCASSERT(nullptr != director, "Director is null when seting matrix stack"); 
    Mat4 oldMV; 
    oldMV = director->getMatrix(MATRIX_STACK_TYPE::MATRIX_STACK_MODELVIEW); 
    director->loadMatrix(MATRIX_STACK_TYPE::MATRIX_STACK_MODELVIEW, _modelViewMV); 
    box2dWorld->DrawDebugData(); 
    director->loadMatrix(MATRIX_STACK_TYPE::MATRIX_STACK_MODELVIEW, oldMV); 
}

我不得不使用'_customCommand.init（_globalZOrder + 1）;'到初始化第e自定義渲染命令，否則Box2d相關的東西會呈現在精靈之後。任何想法熱解決這個？我正在使用cocos2d-x 3.10。 – rraallvv

你怎麼樣用一個DrawNode並將其添加爲一個孩子？如果您要使用您在繪圖樹上管理的節點，那麼維護起來會更容易。

auto myDrawing = DrawNode::create(); 
myDrawing::drawRect(p1, p2, p3, Color4F(255, 255, 0, 255)); 
myDrawing::setLineWidth(2) 
this->addChild(myDrawing);

virtual void draw (cocos2d::Renderer* renderer, const cocos2d::Mat4& transform,uint32_t flags) override; 
    cocos2d::CustomCommand _customCmd; 
void onDraw(const cocos2d::Mat4 &transform, uint32_t flags); 



void linedraw:: draw(cocos2d::Renderer* renderer, const cocos2d::Mat4 &transform, uint32_t flags){ 
     //cocos2d::Layer::draw(renderer, transform, flags); 


     _customCmd.init(1); 
     _customCmd.func = CC_CALLBACK_0(linedraw::onDraw, this, transform, flags); 
     renderer->addCommand(&_customCmd); 

    } 

     void linedraw:: onDraw(const cocos2d::Mat4 &transform, uint32_t flags) 
     {
