Certain Entities are unscriptable?

[gbstrcl]

I do an interact callback between an in-game area script and a function that sets invisible the mesh of a book pile. thats what its supposed to do at least. But nothing happens, and there are no errors telling me what I could've done wrong. Ive quadruple checked all names and everything is consistent. Just the entity doesn't go anywhere, dissapear, or anything. Only the sound plays.

Code: (Select All)

void OnStart()
{  
    SetEntityPlayerInteractCallback("ScriptInteract", "OnInteract", true);
}

void OnInteract(string &in asEntity)
{
    PlaySoundAtEntity("", "BookSlide.snt", "Player", 0, false);
    SetEntityPos("BookPile1", 3000, 3000, 3000);

//set entity pos was after I tried set mesh invisble and deactivate entity. Still nothing.
