Multi- Directional Anvil Cannons

Howdy, folks! Ej here, bringing you another random little goofy redstone concept. You may remember my video a while ago about a little slime- block anvil launcher. :https://www.youtube.com/watch?v=fdvnmBCU5NQ
Well, a few weeks ago, I realized that I could make that exact same concept in a much more compact, resource- efficient way. So I did a little more prototyping, and came up with some different designs of entity cannons. As you can see in the world download, there are several designs I came up with, some shoot farther than others, some are more compact, but my favorite ended up being the two designs in the middle. They fire just a little bit less far than the other designs, but make up for it in compactness. Whereas before, I used tripwire hooks and string, which required a minimum size of 5 blocks wide, using a bud powered activator means much smaller design possibilities. And in comparison to the previous version of this multidirectional anvil setup, I put together a little display to show how much smaller and neater the new one is.
Personally, I think this type of entity cannon would be an interesting design for an elevator, like being launched up over and over again across a valley until you reach the top. Might be a cool design if you have a slime farm, and you don't need to worry about slime... Of course, since these entity cannons were specifically designed for anvils, not 2- high players, so they'd need a bit of redesigning...
Anyways... Happy experimenting with these half- baked concepts! I have only laid the groundwork for some greater mechanics that will appy these things. XD
