我是cocos2d / 3d的新手，我想绘制圆柱但是为了理解我试图在this链接的帮助下在cocos3d中加载三角形的meshnode的功能，但我收到警告不兼容指针类型将'CC3MeshNode *'发送到'CCNode *'类型的参数，并且应用程序崩溃并出现以下错误。
请原谅我的英语。

这是我绘制三角形的代码
static float arr_location[] = {-1.0,0.0,0.0, 1.0,0.0,0.0, 0.0,1.0,0.0};
static float arr_normal[] = {0.0,0.0,1.0, 0.0,0.0,1.0, 0.0,0.0,1.0};

CC3VertexLocations *locationDemo =
[[CC3VertexLocations vertexArrayWithName:@"demoLocation"] autorelease];
locationDemo.drawingMode = GL_TRIANGLES;
[locationDemo setVertexCount:3];
[locationDemo setVertices:arr_location];

demoMesh.material.diffuseColor = CCC4FMake(1.0, 1.0, 1.0, 1.0);

答案 0 :(得分：0)
我已阅读http://brenwill.com/docs/cocos3d/0.6.2/api/interface_c_c3_node.html文档，您必须使用CC3Node基类才能使用CC3MeshNode。
我非常确定“self”是CCNode类型，而不是预期的CC3Node基类。
