将以下代码添加到CCActionGrid3D.h

class CC_DLL CCEllipse3D : public CCGrid3DAction

{public: /** initializes an action with duration, grid size, waves and amplitude */ bool initWithDuration(float duration, const CCSize& gridSize, float alength, float blength, float startangle, float endagnle,float xoffset,float yoffset); /** * @js NA * @lua NA */ virtual CCObject* copyWithZone(CCZone* pZone); virtual void update(float time);public: /** creates an action with duration, grid size, waves and amplitude */ static CCEllipse3D* create(float duration, const CCSize& gridSize, float alength, float blength, float startangle, float endagnle,float xoffset,float yoffset);protected:float m_fStartAngle;//开始角float m_fEndAngle;//结束角float m_fALength;//长轴float m_fBLength;//短轴float m_fXOffset;//X偏移float m_fYOffset;//Y偏移

};

将以下代码添加到CCActionGrid3D.cpp

CCEllipse3D* CCEllipse3D::create(float duration, const CCSize& gridSize, float alength, float blength, float startangle, float endagnle,float xoffset,float yoffset){CCEllipse3D *pAction = new CCEllipse3D();if (pAction){if (pAction->initWithDuration(duration, gridSize, alength, blength, startangle, endagnle, xoffset, yoffset)){pAction->autorelease();}else{CC_SAFE_RELEASE_NULL(pAction);}}return pAction; }bool CCEllipse3D::initWithDuration(float duration, const CCSize& gridSize, float alength, float blength, float startangle, float endagnle,float xoffset,float yoffset){if (CCGrid3DAction::initWithDuration(duration, gridSize)){m_fStartAngle = startangle;//开始角m_fEndAngle = endagnle;//结束角m_fALength = alength;//长轴m_fBLength = blength;//短轴m_fXOffset = xoffset;//X偏移m_fYOffset = yoffset;//Y偏移return true;}return false;}CCObject* CCEllipse3D::copyWithZone(CCZone *pZone){CCZone* pNewZone = NULL;CCEllipse3D* pCopy = NULL;if(pZone && pZone->m_pCopyObject) {//in case of being called at sub classpCopy = (CCEllipse3D*)(pZone->m_pCopyObject);}else{pCopy = new CCEllipse3D();pZone = pNewZone = new CCZone(pCopy);}CCGrid3DAction::copyWithZone(pZone);pCopy->initWithDuration(m_fDuration, m_sGridSize, m_fALength, m_fBLength,m_fStartAngle,m_fEndAngle,m_fXOffset,m_fYOffset);CC_SAFE_DELETE(pNewZone);return pCopy;}void CCEllipse3D::update(float time){ int i, j; for (i = 0; i < m_sGridSize.width&#;1; i&#;&#;){float angle = (m_fStartAngle &#;(m_fEndAngle-m_fStartAngle)*i/m_sGridSize.width)*time;for (j = 0; j < m_sGridSize.height &#; 1; j&#;&#;){ccVertex3F v = originalVertex(ccp(i ,j));v.x = m_fALength*cos(angle)-m_fALength&#;m_fXOffset; v.y = m_fBLength*sin(angle)&#; v.y &#; m_fYOffset; setVertex(ccp(i, j), v);} } }
