Thanks for working it out. I will tell ya when I have figured out something.

Here is a snippet how to associate datastructures with entities:

Code:

---

// some random datastructure

   typedef struct ZUZU {
      char  frame [128];
      var   speed;
      var   mode;
   } ZUZU;

// associate datastructure

   ENTITY* ent = ent_create(...);
   ZUZU* dingDong = ...
   ent->skill[10] = (long)((void*)dingDong); //link datastructure with skill

// retrieve datastructure

   ZUZU* fooBar = (ZUZU*)(ent->skill[10]);
