I'm relatively new to Minecraft. I've built a few shelters on a few worlds, usually with a high level of success. However, I've recently been trying to spruce up these shelters and make them nicer-looking. Part of that is adding windows--both for the nice look and to make it easier to determine the time of day. So far, I've only added windows in rooms away from my bed, since I am not sure about the safety of glass.

I know that unless they are in pursuit mode, non-spider mobs cannot see a player through glass. Spiders are not a problem, because they just congregate and make noise on the roof. The Glass Page on the wiki says that "Spider Jockeys can shoot their arrows through glass and cause damage.[citation needed]"

So, two main questions:

  1. Can Spider Jockeys shoot through glass or not? Is this intentional or a bug? Is it something I need to worry about, since they spawn so rarely anyways? (I've only ever seen one)
  2. Are there any other perils I need to worry about with regards to using glass as windows or skylights?

    Windows aren't dangerous as long as they're properly secured.

1 Answer 1


Spider Jockeys are simply Skeletons riding Spiders, and I know for a fact that Skeletons can't shoot their arrows through glass. If they can, it's most likely a very rarely occurring bug – the fact that there's no citation for that point makes it hard for me to believe. It's not something you need to worry about. (Also, there's nothing on the Spider Jockey page about being able to shoot through glass.)

Glass is just as good as any other block when it comes to safety. The only thing you might worry about is if a Creeper were to explode near your windows, the glass would absorb less "blast damage" and more of your house may get destroyed, as glass has a very low blast resistance rating.

  • But a Creeper wouldn't explode unless it was pursuing either me or another player, correct? If a Creeper walks up to the windows where I am looking at it, it cannot see me, and thus will not explode, right?

    Yeah, it won't explode. Glass still acts as a solid block to mobs. I was only referring to if he was stalking you around the outside of your house.

    One disadvantage of windows is that they can be terrifying.

    @fredley: This is why all my abodes are either underground or over ground. If I look out my window I want to see rock, or a creeper falling to his death. There is no in between. Commented Aug 17, 2011 at 19:21
  • Heh, I remember one time when I mined one block out of my wall at head height, and there was a creeper literally two blocks away on the other side of the window, looking RIGHT at me. I put the glass in in a hurry, let me tell you. Commented Aug 18, 2011 at 16:10
