Custom mob attack issue

[justjasper]

I'm working on a custom mob (based on the gobbler/perd) which has an attack, I've got aggro and chase all sorted, but I can't seem to work out how to make it so it can attack a player while being hit like many other mobs do. Instead the mob is locked into a hit animation with each blow and never getting to land an attack, unlike say a tallbird, which will get hit a few times then land a sucessful attack if the player doesn't move, even if said player is still striking it. I've been comparing stategraph codes and experimenting and can't seem to work out how to do it. Anyone able to point me in the right direction?
