c - 如何正确访问此结构中的指针？

Question

下面是 2 个结构的定义，然后是使用它们的简短方法体。我不明白为什么编译器会抛出错误:

physics.c:95: error: incompatible types in assignment

cpBody 和 cpSpace 是来自外部库的类型，这不是问题的一部分。

typedef struct gameBody gameBody;

struct gameBody
{
    cpBody *body;
    int numberOfShapes;
    cpShape *arrayOfShapes; //This stores an array of pointers to Shapes
};

//Struct that stores the cpSpace object and the array of pointers to the body objects
typedef struct gameSpace gameSpace;

struct gameSpace
{ 
    cpSpace *space;
    int numberOfObjects;
    gameBody *arrayOfObjects;       //This stores an array of gameBodys
};

void physicsAddBody(gameSpace *space, gameBody *body, int objectIndex)
{
    gameBody *array = space -> arrayOfObjects;
    array[objectIndex] = body; //THIS IS WHERE THE ERROR IS THROWN
}

Answer 1

array[objectIndex] = body;

左边是gameBody，右边是gameBody*。

您是尝试复制结构还是将指针分配给指针数组？
