Making skeletons shoot explosive arrows

Solution 1:

The simple answer is, that currently, there is no 'native' way to do this in minecraft. (At least not from what I've seen).

From 'native' I mean producing the desired effect without making any modifications to your Minecraft Client.

Meaning, right now, there are only two ways to get skeletons to shoot explosive arrows:

• Wait till it's added into minecraft (Though, no guarantees that it will be ever officially added into minecraft)
• Suggest a mod idea here. (More info below)

The link is to minecraft forum's "Requests / Ideas For Mods" section, which is where you will be able to (hopefully) find someone who is willing to fulfill your request.

Hope this helps.

Solution 2:

At this point you have two options to get that feature implemented:

• Request a mod be created
• Learn Java and use the Minecraft Forge SDK to create a mod

Of course, there is also the remote possibility of making an insane Redstone contraption using TNT spawners and such, but that is probably harder than implementing it using a mod.

Solution 3:

It is possible to make exploding arrows not shot by skeletons:

• Fire an arrow, and exit the game before it lands
• Use SethBlings MCEdit filter for stacking entities to stack primed TNT on top of the arrow and make a spawner
• You now have a spawner that fires exploding arrows!
