Minecraft: Rocket Launchers - The Chance Rocket Launchers Deserve
I'd like to give credit to PizzaSHARK in the forums for this idea, and while I believe I have made it significantly my own, he deserves much of the credit. Link to his original idea at the end.
While many people today are into the idea of rocket launchers in Minecraft, they're thinking of a weapon, which, in my opinion, will never make it into vanilla, but that's what mods are for. However, not many people see the real possibilities of rocket launchers - not as a weapon, but as a tool.
This would just be a tube with handles that can fire a projectile in the direction it's pointing. The basic crafting recipe would look something like this for the actual tool:
[empty] [redstone] [empty]
[gold ingot] [bamboo] [iron ingot]
[stick] [empty] [stick]
Why this? The gold will form a tube to guide the projectile, iron serves as a strong base that can take the explosion, redstone as the ignition system, and sticks handles.
Bamboo forms the base to work with, and also makes it more realistic, since the Chinese made something similar around the 1100s, and seeing that those were weapons all the way back then, and Minecraft's technologies weren't all around in our world till about 122 years ago, it seems like it's not too much of a wild idea.
(Plus, for all you people who think Minecraft is medieval, try making two diamonds and a stick into a fully functional sword. TODAY.)
This rocket launcher would take about 80 shots to break and would be repaired with itself in an anvil. It would only deal 3 hearts on a direct hit, with 0.5 - 1 heart in the blast radius. It would also have around 3 knockback. In short, it would be much weaker than just using a knockback enchanted bow (5 hearts fully charged). Also, it can only destroy:
dirt + variants
cobblestone + variants
sand + variants
So basically, creepers can break the same blocks as this, making it a mineshaft builder, not a troll weapon. (But hey, we can always knock innocent sheep of mountain cliffs too. Heh heh.) It would dig about 4 blocks deep. It would also push you away from the central point of explosion in all directions, allowing you to jump/run higher than usual (aka rocket jump). Finally, it would drop all blocks it destroys, including mob heads, since TNT does in 1.14 on.
Now for the projectiles. These will basically be an iron shell with fins to keep it straight and ignite the fuel and what will explode. For a recipe, it would look like this:
This will travel 12 blocks or impact before exploding. However, gunpowder rockets will only make a 2 by 2 hole 3 blocks deep, compared to the standard fire charge rocket (5 blocks deep, 3 by 3 blast radius). The recipes would make 2 of each, respectively, and they can stack up to 16. This means 5 stacks of rockets will fully use a rocket launcher, so keep that in mind.
In addition to being superior to gunpowder rockets, you can use or upgrade fire charge rocket projectiles into piercing or rebounding projectiles. Piercing projectiles are a fire charge rocket projectile plus a diamond directly over it. These will go into walls or players, dealing 3.5 hearts on a direct hit and blowing up 9 blocks deep instead of 4. Rebounding projectiles are a slimeball directly over a fire charge rocket, and won't detonate on impact with anything, but simply bounce off in the other direction and travel till it goes its full 12 blocks. It can bounce infinite times till it explodes.
Now for some wrap-up stats:
Rocket launchers take 2.5 seconds to reload directly after the projectile leaves the barrel, regardless of type, and has instant shots once fired.
Turning off "TNT Explodes" makes projectiles simply give off a white shower of particles when they would have exploded.
The only enchantments compatible with the rocket launcher is unbreaking and mending and costs 3 levels with anvil (not compatible with enchanting table).
So in conclusion, I hope this will gain enough support to actually make it into Minecraft Vanilla. I and my associates are working on a mod to showcase how this would work, which we will post in an addition to this, so look out for that. But until then, please...
Launching explosives doesn't feel like a very Minecraft-ish idea. And I don't think I'd want to see this in a multiplayer game. I mean, you could just set up a bunch of TNT instead of reloading this launcher thing every time.
