So yeah, I'm back again. I've been quite busy recently with my Naruto Data Pack (It's actually rather close to alpha release, I feel that once I perfect custom crafting, add a jutsu for all five chakra natures, and add kunai and shuriken I'll release it in alpha stage!) but one thing has been bugging me. For a lot of my planned jutsu (and the kunai and shuriken) I need to be able to do raycasting. What is the most effective method for that? I want to use armor stands, stop when it hits a wall or mob, and have configurable results when it hits both of those. Thanks in advance for any help I (hopefully) get. Oh yeah, and thanks everyone for your support on the Naruto Data Pack, it means a lot to me!

EDIT: I managed to come up with my own way which is relatively simple, but if you have an answer you can still tell me.
