创建3D模型/添加屏幕监听，点击屏幕时，精灵带有旋转的移动



3D模型创建 //3D models auto model = Sprite3D::create("Sprite3DTest/boss1.obj"); model->setScale(4); model->setTexture("Sprite3DTest/boss.png"); model->setPosition3D(Vec3(s.width/2, s.height/2, 0)); addChild(model);

EventListenerTouchOneByOne 监听EventListenerTouchOneByOne* _lis = EventListenerTouchOneByOne::create();_lis->onTouchBegan = [this](Touch* t,Event* e){CCLOG("onTouchBegan");return true;};_lis->onTouchMoved = [this](Touch* t,Event* e){CCLOG("onTouchMoved");float dx = t->getDelta().x;Vec3 rot = _camControlMode->getRotation3D();rot.y += dx;_camControlMode->setRotation3D(rot);Vec3 woldPos;_camNode ->getNodeToWorldTransform().getTranslation(&woldPos);Camera::getDefaultCamera()->setPosition3D(woldPos);Camera::getDefaultCamera()->lookAt(_camControlMode->getPosition3D());};Director::getInstance()->getEventDispatcher()->addEventListenerWithSceneGraphPriority(_lis,this);

添加屏幕监听，点击屏幕时，，精灵带有旋转的移动HelloWorld::HelloWorld(){auto listener = EventListenerTouchOneByOne::create();listener->onTouchBegan = CC_CALLBACK_2(HelloWorld::onTouchBegan,this);listener->onTouchEnded = CC_CALLBACK_2(HelloWorld::onTouchEnded,this);_eventDispatcher->addEventListenerWithSceneGraphPriority(listener,this);

auto sprite = Sprite::create("Images/grossini.png");auto layer = LayerColor::create(Color4B(155,55,0,25));addChild(layer,-1);

addChild(sprite,0,kTagSprite);sprite->setPosition(20,150);

sprite->runAction(JumpTo::create(4,Vec2(300,48),100,4));layer->runAction(RepeatForever::create(Sequence::create(FadeIn::create(1),FadeOut::create(1),nullptr)));

}

bool HelloWorld::onTouchBegan(Touch* touch,Event* event){return true;}

void HelloWorld::onTouchEnded(Touch* touch,Event* event){auto location = touch->getLocation();auto s = getChildByTag(kTagSprite);s->stopAllActions();s->runAction(MoveTo::create(1,Vec2(location.x,location.y)));float o = location.x – s->getPosition().x;float a = location.y – s->getPosition().y;

float at = (float)CC_RADIANS_TO_DEGREES(atanf(o/a));//反atanf

if (a <0){if (o<0){at = 180 + fabs(at);}else{at = 180 – fabs(at);}}

s ->runAction(RotateTo::create(1,at));}

世上再美的风景，都不及回家的那段路。
