Creeper does not burst if to shut the door

Wall = Block view of creeper?

It would be nice in Hard Mode, if losing line-of-sight didn't cancel the explosion. Creeper could make a guess based on how much time passed since it saw you, and based on the materials in between, whether you're still in its blast radius.

Although I think this whole ticket might be a feature request.

But this is a bug ! He does not explode when I'm in the house!
