Zero G TNT is a datapack that removes gravity from primed TNT, making it float, drift, and behave unpredictably. This enables zero-G TNT cannons and related physics breaking builds.
Features
- Removes gravity from all primed TNT
- TNT will drift in a straight line when given motion (e.g. from another explosion)
Design Goals
- Minimal other changes to vanilla behavior
- Easy to integrate to integrate into existing worlds and servers
Eperimental Mode 2
An optional experimental mode can be enabled within the datapack. Navigate to the info page through the chat menu in game, and click where it says to toggle mode.
This does changes how the datapack works in the following ways.
- TNT is now normal again, affected by gravity
- Instead you can craft and use a separate Zero G TNT item
⚠️ Warning: Mode 2 is unstable, and may cause unexpected behavior or damage the world. Fixes may be implemented at a future date.
