Introducing Minecrafts Precision TnT Cannon

It's finally here! A TnT cannon that can aim and shoot using dirt cheap redstone mechanics, but it turns out to make something as simple to build and powerful as the Smart Artillery requires some super advanced mathematics outside of the game to give us our firing options. In this video we will learn about the ballistics of TnT cannons and how we can model these ballistics using advanced software.

[@paulkanja]

Technically a cannon, not artillery: artillery is a subtype of cannon has (at least) two phases and targets the top of a target (so the tnt flies up above the height of the target, then a portion of the tnt explodes causing the rest to change trajectory and aim downward) as an aside, an even more specialised artillery canon is an airstrike: the tnt is redirected straight down when directly above the target... pretty wonderful field when it comes to tnt weapons

[@laff__8821]

Cannons in ancient rome?

[@ATOM-vv3xu]

actually finding the right setting for a cannon becomes very intuitive after you shot it for some hours

[@cubicmetre]

I think it would be possible to operate the cannon in full vanilla using intuition alone. And the mod is actually a great way to start. I'd imagine if you needed to use the cannon in a setting where you were not allowed the mod, you could train using the mod in singleplayer then transfer this knowledge to online play. The way I see it, is that the cannon gives a good suggestion for a setting, then you can tweak that setting to get slight variations of the firing option. As you learn to tweak more and more you find that you get a feel for what settings hit approximately which positions.

[@salos4467]

I like it very much that the rest of the world is now starting to look at tnt. There is the wargear scene, which is currently completely German, where people are in teams trying to build the best cannons together and then build them into so-called wargears. "Wargears" are fighting machines equipped with cannons and shield technology, sometimes even automatic cannons, which are then used to compete against other teams in tournaments. There is a fixed set of rules to guarantee fairness. For example, any block that has a higher tnt resistance than endstone is forbidden, and dispensers may not be used for tnt. In tournaments, the redstone blocks are replaced by endstone for every spectator except for the own team to prevent the theft of cannons. It's really cool every year in the "WargearLiga" to see what the teams have built, sometimes thousands of hours on their cannons, and to see which one wins best. There are currently 2 servers in the Wargear scene. Although the Wargear scene has existed for over 8 years, it unfortunately only has around 200 active players to date, I think because it is simply too difficult and complicated for most. If anyone has any questions just write or send me a message. Have fun building 👍 By the way, you play completely in Vanilla without mods.

[@adamofblastworks1517]

Do you think you can aim a tnt towards another tnt mid air to change it's trajectory? Like you fire a bunch for tnt that actually contains the payload and propellent.

[@cubicmetre]

In my mind atleast I can imagine a client mod that can track nearby entities and extrapolate their positions based on their motion and in theory set the cannon and fire on a moving target all autonomously. However you are always limited to the delay from the redstone and TnT fuse time. This is why artillery are usually restricted to static emplacements because it's really hard to hit a moving target if there is a lot of time between acquiring the target and being able to hit it.

[@anonymous-rb2sr]

@@ghostly9835 isn't the end platform literally always blocked by line of sight by an obsidian pillar from where the dragon is? (I assume he spawns above the portal at the center) Also how would you not die to your own arrow when going into the portal, does the end generate when the portal is lit or when the player crosses for the first time? Likely the latter, so you would both spawn in the same position and the arrow would be colliding with your hitbox during it's first tick in the end, I can't see that going well either

[@lygencore]

If this is even feasible, it is not worth it, because it means you need to look for redstone and other components (also more iron) and a whole lot of tnt to get enough strength in the arrow, which also means you need to begin your run in a desert and hope to find more than 1 desert temple, plus you need a village right next to it to get the iron. What I mean is that from whatever materials is build the arrow cannon, getting them would take a lot more time than waiting for a perch (for one cycle)

Yeah, I was trying for years to build something like this. But not being a big Minecraft person, I just couldn’t get the timing right beyond a handful of horizontal and vertical presets that needed different timing to reach the same distance. I never once thought about using water to alter the angles, goddamn engineering genius. The math isn’t that hard if you know what you’re doing, but knowing what you’re doing is easier said than done. Still, even without calculus, it should be doable for someone who finished high school. Although that could be my years of crying over intermediate level calculus problems talking. So your mileage may vary. The coding and modeling is genius tier though, MatLab is pretty easy, but that’s a lot of complicated steps to make work explained in an incredibly straightforward manner. Thank you so much! This is a dream come true for me!

[@gustavbw]

I have a challenge for you: shooting around corners. That smart artillery seems to be consistent and precise enough to launch a payload (henceforth: redirection payload) + a projectile to be redirected mid air. It should theoretically be possible but to simplify, you could build a prototype that only shoots straight, and then just varies the position of the redirection payload in relation to the position of the projectile at that point in time. Using entity tick control like the extreme rail gun tnt cannons do, should allow you to fire a payload so large (actually probably not that big) that just 1 tick of delay between the launched payload and the actual projectile exploding should be enough to get a very large point cloud of possible coordinates. Taking the smart artillery approach would leave you with 5 degrees of freedom for the limited prototype: 1. ignition delay of projectile 2. x position of redirection payload in relation to the projectile 3. y position of redirection payload -||- 4. z position of redirection payload -||- 5. ignition delay between the static payload and the redirection payload + projectile. This would, theoretically, allow you to hit any coordinate in a sphere with a radius depending on the size of the redirection payload, at a set offset away from the cannon in the direction it is facing depending on the size of the payload. Also yes I just noticed there's a major caveat in this. When reaching for medium distances, bullet drop takes effect. Now this is sorta counter-acted by the fact that both the redirection payload and the projectile has the same ballistic arc, but it will still mean that you have to vary the size of the initial payload (and increase d.o.f. 5) to compensate. But still doable! (theoretically). Now, for actually building the prototype, I think dropping the redirection payload into a 3m^3, alining it with pistons/water streams/water-elevators/!water-elevators (I've seen Ilmango do some crazy entity alignment magic) and then dropping the projectile tnt into this space timed with the explosion of the payload is a valid way to go. I know a limited version is possible, but getting that full 360 degree sphere is probably going to take a whole lot of math and timing.

[@kinkysergal1085]

So you obtained a closed form solution for the ballistics of the payload TNT. Impressive. I have been working on a research project in real life where the ballistics of an axisymmetric projectile is solved iteratively. The 6 DOF equations of motion are 12 coupled differential equations that are solved simultaneously. MATLAB solving is simple but I'll have to see what happens when I try this on a microcontroller haha

damn bro this actaully helped me learn spec maths vectors

Excellent video as usual ! I was thinking about something but maybe it can't work : instead of push the "bombshell" tnt with piston and water, do a vertical set above the system, this set can allow us to make fall down multiple TNT at the same time on a specific block. However it would be less precise but the extra damage would cover this inaccuracy. (Sorry for bad english I wish you understand what I mean)

Bro really derived the guidance and control laws for a minecraft TnT cannon.

This is amazing!!!

"like this heavy caliber stationary smart TNT artillery designed by me, built by me"

[@eliklappenbach2426]

A small but extreme smart machine. Never thought I would see calculus put to work to solve problems in Minecraft

Amazing, we are waiting for more "Smart" thing such as this.

this is just amazing
