I need using some user data (like ItemIndex, ItemType, Attribute...etc)which linked to an entity. Now I get the Entity's pointer, how can I access those data?

I try to do this:
Using a struct collect the values,

and then create a Item implementation in game,
use c_trace get the target pointer what I touched,
now I want to show the target name, how can I using the pointer(T_Item->pItemEnt) to get other struct members (T_Item->pszItemName)?

Thanks to read.

u mean here u have many entities. so u should create an array of the struct instead. and access using the index to differentiate between each entity.

cause from your coded, the pointer T_Item->pItemEnt is the same structure as T_Item->pszItemName. both are members of same structure.

Thanks delinkx.
yep, I got the pointer of the entity, and I don't know which T_Item instance contains it, I want to find the entity's parent struct inst and using other members in it.

An array of struct to collect entities is a member of higher level object "Item Collecter". I mean I catch a pointer, use it drawing a Item struct out of items and don't want ask everyone "Is this pointer yours?"

The best way Ive found is, when adding the entity to the struct inst,
store a pointer to the struct inst in one of the entity skills,
or its "reference" number as it is stored in the "item collector".

I sometimes store a VOIDed pointer to the struct inst in the
"entity.parant" pointer too. Only if not using templates for anything.

That way T_ITEM can directly access ENTITY with T_ITEM->pItemEnt
and ENTITY can directly access T_ITEM with (T_Item*)ENTITY->parent

Thanks EvilSOB.
I forgot the skills...
