将struct Array复制到另一个struct Array (GLKVector)

Question

我尝试将vertexDataTextured ArmandDeBrignac[]数组的内容复制到vertexDataTextured MeshVertexData[]数组。但是行不通....我认为问题是在结构方法，有GLKvector元素.....

?

这是我的头文件:

struct vertexDataTextured
{
    GLKVector3      vertex;
    GLKVector3      normal;
    GLKVector2      texCoord;
};
typedef struct vertexDataTextured vertexDataTextured;
typedef vertexDataTextured* vertexDataTexturedPtr;

vertexDataTextured MeshVertexData[] = {}; 
vertexDataTextured ArmandDeBrignac[] = {
    {/*v:*/{-0.979979, -2.383373, -1.142941}, /*n:*/{0.000000, -0.725242, -0.688467}, /*t:*/{0.794971, 0.247112}},
    {/*v:*/{-0.859054, -2.367034, -0.829303}, /*n:*/{0.023591, -0.999512, 0.019593}, /*t:*/{0.786435, 0.224949}},
    {/*v:*/{-1.056731, -2.383373, -1.142941}, /*n:*/{-0.337657, -0.631642, -0.697836}, /*t:*/{0.800393, 0.247114}},
    {/*v:*/{-0.979979, -2.117816, -1.142941}, /*n:*/{0.000000, 0.500198, -0.865902}, /*t:*/{0.645127, 0.391262}},
    {/*v:*/{-0.979979, -2.383373, -1.142941}, /*n:*/{0.000000, -0.725242, -0.688467}, /*t:*/{0.663889, 0.391205}},
    {/*v:*/{-1.056731, -2.383373, -1.142941}, /*n:*/{-0.337657, -0.631642, -0.697836}, /*t:*/{0.663906, 0.396627}},
    {/*v:*/{-0.993670, -2.036772, 0.915066}, /*n:*/{-0.771722, 0.588244, 0.241585}, /*t:*/{0.293949, 0.430232}},
};

@interface FlaschenManager : NSObject
-(void) getFlaschenID: (NSString* ) Name andTexture: (NSString*) path;
@end

and my .m File

@implementation FlaschenManager
-(void) getFlaschenID: (NSString* ) Name andTexture: (NSString*) path
{
    if ([Name isEqualToString:@"ArmandDeBrignac"])
    {
        NSLog(@"%@",Name);
        MeshVertexData[0].vertex.v[0]=ArmandDeBrignac[0].vertex.v[0];
      //  MeshVertexData[] = ArmandDeBrignac[];
    } else if ([Name isEqualToString:@"Hennessy"])
    {
        NSLog(@"%@ ", Name);
        FlaschenName = Name;
    }
} 
@end

可以试试这样

vertexDataTextured ArmandDeBrignac[] = {
    {/*v:*/GLKVertex3Make(-0.979979, -2.383373, -1.142941), /*n:*/GLKVertex3Make(-0.979979, -2.383373, -1.142941), /*t:*/GLKVertex2Make(-0.979979, -2.383373)
}

你也可以选择

MeshVertexData[0].vertex = ArmandDeBrignac[0].vertex;

如果你试图访问顶点的索引0，那么使用它的xyz组件代替

MeshVertexData[0].vertex.x = ArmandDeBrignac[0].vertex.x;

根本没有测试过，但这是一个建议
