MC_PRE_GRID_X_DESTROY
The ability to test/cancel grid damage (damage to grid entities, not from them) would be incredibly useful
I've wanted to add this, but some GridEntity's Destroy functions are just Hurt(4) and that brings about logistical issues I'm not sure how to handle
It may be a good idea to provide callbacks for when the GridEntity is hurt as well, at least as a temporary solution, as well as being able to check how much health they have/have left (if that's not already possible, I wouldn't know, my experience with the Isaac API is very limited, but I assume it wouldn't be the case because that sounds actually convenient).
Despite explicitly being able to Hurt and Destroy them, GridEntity has no Health variable; it's left completely up to each subclass to decide how to interpret that damage. Why? Not sure! Blame Florian and/or Nicalis.
It's exactly that potential hurt callback that throws a wrench into things; neither really makes sense to have without the other. From there, how do I deal with those default functions that just call Hurt? Do I allow both callbacks to fire? Do I block the Hurt callback from firing to keep the illusion that the two functions are separate things?
