Question about Collision Boxes

[TH3Doctor_11th]

Hi Everyone I recently got back to minecraft modding.. and last week I asked something about Techne. I am clearly making a mob, but here s a new dilemma: I would like to make it completely uncollidable. Entities and player should pass through it. I have seen that noppes, in his CustomNPCs, has done something to make it possible. But i really can't get how he does it. Is there someone who knows how to do it? Am I missing something really simple? Thanks in advance.
