bool THelloWorld::onTouchBegan(TTouch* touch, TEvent* event){auto sprite =  (TSprite*)(this->getChildByTag(1000));  static int nTempIdx = 0;switch (nTempIdx++){case 0: // 移动到鼠标的位置{sprite->runAction( TMoveTo::create(1, touch->getLocation()));} break;case 1: // 往右边移动 200.0f{sprite->runAction( TMoveBy::create(1, TPoint(200.0f, 0.0f)));} break;case 2: // 倒着执行 往右边移动 200.0f, 这里等于往左移动 200.0f{sprite->runAction( TMoveBy::create(1, TPoint(200.0f, 0.0f))->reverse());} break;case 3: // 跳到鼠标的位置, 跳高度50,  跳4次{sprite->runAction( TJumpTo::create(1, touch->getLocation(), 50, 4));} break;case 4: // 往右边跳 200.0f 跳高度50,  跳4次{sprite->runAction( TJumpBy::create(1, TPoint(200.0f, 0.0f), 50, 4));} break;case 5: // 倒着执行 往右边跳 200.0f{sprite->runAction( TJumpBy::create(1, TPoint(200.0f, 0.0f), 50, 4)->reverse());} break;case 6: // 贝塞尔曲线.. {  TBezierConfig bezier;bezier.controlPoint_1 = g_ClientMidPoint;bezier.controlPoint_2 = TPoint(300.0f, 50.0f);bezier.endPosition    = touch->getLocation();sprite->runAction( TBezierTo::create(1, bezier));} break;case 7: // 贝塞尔曲线.. {TBezierConfig bezier;bezier.controlPoint_1 = g_ClientMidPoint;bezier.controlPoint_2 = touch->getLocation();bezier.endPosition    = TPoint(100.0f, 0.0f);sprite->runAction( TBezierBy::create(1, bezier));} break;default:{nTempIdx = 0;}}    CCLOG("THelloWorld::onTouchBegan id = %d, x = %f, y = %f", touch->getID(), touch->getLocation().x, touch->getLocation().y);    return true;}

关于贝塞尔曲线,,实在是难以理解.

可以参考这几篇博客
