Brittle Bedrock
I don't know my version or loader
Open the Minecraft launcher and look at the profile you play on — it names both, like fabric-loader-1.21.4. The version also shows in the bottom-right corner of the game's main menu.
No loader in the profile name? Then it's plain Minecraft, and these mods won't run — you need Fabric or NeoForge installed first.
Brittle Bedrock
Weaken bedrock with dense TNT explosions.
Content
- Craft Dense TNT with 9 normal TNT.
- Place Dense TNT on bedrock to weaken it.
Technical Concept
- The advancement is triggered when a TNT item is placed on a bedrock block, but only if the TNT item has the custom data component added by the crafting recipe.
- Then, the advancement triggers a raycast from the player's head to determine the position of the newly placed TNT block.
- The TNT is replaced with primed TNT with a 0-tick fuse (instant explosion), and all neighboring bedrock blocks are replaced with obsidian.
- The raycast extends up to 5 blocks (normal placement range) in 0.1 block increments, for a maximum of 50 steps.
- There can be instances where the raycast does not find the TNT block. For example, this can happen when the cursor is at the very edge of the Bedrock block, and the 0.1-block steps are not fine-grained enough.
- When custom TNT is placed (not against bedrock), broken, and picked up again, it reverts to normal TNT, losing the custom data component.
