3) How to call an entity's script LUA function easely (without parameters)

That's really easy. Suppose you have an entity in your scene with a script attached in which a function "noParams" has been declared

function Script:noParams()
  System:Print("executing noParams")
end

using the loop exposed on tut 2/7 of this series, you can find that entity and then, to call one of their functions you only have to do:

entity->CallFunction("noParams"); // yes only the name

also you may check if the entity has a script at all:

this is a more generic function to call functions with no parameters:

void call_noParams(Entity* e, string funcName){
  if (e->script != NULL)
    e->CallFunction(funcName); // CallFunction only if entity has a script attached
}

that's it!
