Instructions

If used incorrectly, the cannon can accumulate enough TNT in lazy chunks to crash and ruin the world. Creation of a world backup is recommended.
The cannon is designed for the Nether, do not build it in the Overworld.
Using the cannon in a Basalt Deltas will leave some leftover blocks.
Use the [calculator](<https://docs.google.com/spreadsheets/d/1kesIo_hdweXiTAuLGICUM36A6ZmiYgs4eFzXmNnBO_8>) to obtain an estimated completion time.
Trench length is constant, regardless of perimeter size.
The schematic sub-regions contain info about containers and trenches.
Item entities are automatically destroyed.
After running the cannon, a [Nether Sweeper](https://discord.com/channels/1161803566265143306/1445142786906259528) can be used to clear the lava.

Sub-chunk align the schematic to the nether roof according to the purple glass.
Build a nether portal chunk loader in each of the chunks marked with purple glass.
Fill the containers according to Figures 1-3, where "N" and "TNTs per point" are found using the [calculator](<https://docs.google.com/spreadsheets/d/1kesIo_hdweXiTAuLGICUM36A6ZmiYgs4eFzXmNnBO_8>).
Hopper may be filled with any 64-stackable item.
Droppers must be filled using arrow items.

1. Ensure player render & simulation distance is 16.
2. Right click the note block on the waiting platform and ensure the redstone lamp turns on.
The player can leave while the cannon is running.
The cannon and perimeter area must not be loaded while the cannon is running.
3. After the redstone lamp turns off, wait a few minutes.
If using [Chunk Debug](<https://modrinth.com/mod/chunk-debug>), verify the cannon is no longer loading chunks in the perimeter area.
4. Load the perimeter area.
