1.9 snapshots are now coming out, so of course I have been playing with them and command blocks to see what is possible. Less focused on changing mechanics, rather tools for securing LVS or improving the experience for new players on Zurvival and LVS.
Today I had inspiration for how to guide players to a destination. On LVS we try to guide new players to the Community Farm and then the Community Warps using coloured glass in the path, but many miss the signs explaining this and don't understand what the coloured glass in the path means. So, I have created this in 15w32c:

It uses ShulkerBullets for pathfinding through an underground tunnel, with an invisible ArmorStand with a CustomeName being continuously teleported to 2 blocks above the ShulkerBullet. The ShulkerBullet is targeting an invulnerable Creeper, which it hits at the end of the video causing the ArmorStand to shoot up into the air, never to be seen again.
It's not perfect, but this is where I got to today. I thought some of you may be interested in what I get up to on the snapshots, let me know if you are and if you'd be interested in seeing more or perhaps more of the technical details
