i am new to the cocos2d/3d ,i want to draw cylinder but for understanding the functionality i am trying to Load a meshnode of a triangle in cocos3d with help of this link, but i am getting warning Incompatible pointer types sending 'CC3MeshNode *' to parameter of type 'CCNode *' and application crashing with below error.
please forgive for my english.
