I am trying to create an array of pointers that can point to another array that stores addresses to array indexes where the arrays in question are many different types.
I am trying to create entities that can have components added to them. These components are nothing more than indices in an array which are stored in structures. I want to be able to allocate these component structure of arrays dynamically, and so, I can't just use the entity ID to lookup the entry I want... perhaps I making this more difficult than it needs to be. :/
I would appreciate any useful suggestions to make this simpler than the complicated mess I have thought up. :)
This is what I have so far:
1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18 19 20 21 22 23 24 25 26 27 28 29 30 31 32 | typedef struct
{
uint32* x;
uint32* y;
uint32* z;
} Positions;
Positions* allocate_positions_array(uint32 amount)
{
Positions* positions = malloc(amount * sizeof(Positions));
return positions;
}
void free_positions_array(Positions* table)
{
free(&table);
table = NULL;
}
void add_position_component(uint32 entity_id, Positions* positions, uint32 px, uint32 py, uint32 pz)
{
uint32 array_size = sizeof(*positions) / sizeof(positions);
for(uint32 iter = 0; iter < array_size; iter++)
{
if(positions->x[iter] == 0)
{
positions->x[iter] = px;
positions->y[iter] = py;
positions->z[iter] = pz;
}
}
}
