In my .lua file I got the following:

ActorSetPrimitive(actor, primitive);

now... I ll rather do something like this:

actor = CreateActor("ActorCube");

primitive = CreateCube("CubeName", 1, 1, 1);

actor->SetPrimitive(primitive);

Assuming actor is a table (if it it's then your need to use a table), try this instead of your last line above:

actor.SetPrimitive = ActorSetPrimitive

actor:SetPrimative(primative)

Otherwise,

a = { }

a.ptr = actor

a.Set = function(a, prim) ActorSetPrimitive(a.ptr, prim) end

a:Set(primative)

Basically x:y(...) expands to x.y(x, ...)

Hope that helps.  I may have missed the point since your actor->xyz looks more like C++ than Lua.
