Description:
Place the Artillery Gun as a 16x16x16 multiblock by right‑clicking (it needs clear space and breaking any part of the structure destroys it and returns the single gun item), and throw a Smoke Grenade (right‑click to throw) to call in an artillery strike: each Artillery Gun within 100 blocks fires three staggered TNT shells from a visible muzzle point that travel in a smooth ballistic arc with up to 10 blocks of spread. This update improves long‑range reliability by compensating muzzle velocity for distant targets, fixes ballistic timing so rounds reach their aim point, makes the TNT fuse dynamic (with a small safety buffer) so shells detonate shortly after landing, and adds a launch sound at the gun.

User request: Add a large placable 3d artillery gun as pictured. Only allow it to be placed if there is space for the entire thing. And have it all break (and drop the item) if hit on any block. Edit v2: Add throwable smoke grenade that when thrown, any artillery gun within 100 blocks will fire down 3 tnt on the landing point. Edit v8: It looks like the game crashed with the following stacktrace: ---- Minecraft Crash Report ---- // Oops.

Edit v10: Awesome the smoke grenade is working now! but for the TNT being launched, can you a) make sure it's getting launched from the artillery gun TO the destination with a nice arc (with a fuse such that it will explode within 1 second of landing). and b) add some variance to where the TNT is actually landing and WHEN it gets fired. so it should be within 10 blocks of the smoke and the 3 tnt should fire at a .5-2 second interval (with a nice explosion sound) Edit v11: The fuse time isn't correct (it's far too short), the TNT also needs to be starting from maybe like one block higher Edit v12: Add a sound when it fires. Also the fuse needs to be about 1.5 seconds longer. And it's not properly hitting further away targets right now, it falls short Edit v13: We're so close!! the only issue is that the TNT is still falling far short of distant targets. Make sure the trajectory and fuse time is correct for the position of the target.
