If you define to many arguments with context->SetArg*() the function will just not be called. For example if someone who is making an npc for my game forgets to define all the arguments in the event like this:

bool OnWarpCollision(const string& level)
{
  PrintLine(level);
  return true;
}

When it should look like this:

bool OnWarpCollision(const string& level, float x, float y)
{
  PrintLine(level);
  return true;
}

The first one will not be called because i use: SetArgAddress(0, level); SetArgFloat(1, nextX); SetArgFloat(2, nextY); Maybe you could make it ignore the SetArg() if the argument isnt defined

I think that may be a bit drastic, not all applications may want to simply ignore it.

Instead I'll provide a way for you to determine the number of arguments and the argument types for a function. That way you can decide for yourself whether to call the SetArg function or not.
