# Mock TNT |
|||
Mod for Minetest |
|||
|
|||
## Usage |
|||
* Place in mods folder such as in your subgame |
|||
* "Unknown Explosive" (mock_tnt:mock_tnt) can coexist with TNT if TNT is enabled, but gunpowder and mock_tnt work even if enable_tnt is false. |
|||
|
|||
## Differences from regular TNT |
|||
* Does not harm any block or entity |
|||
|
|||
## Known Issues |
|||
* also ignite gunpowder with "default:torch", "fire:permanent_flame" (minetest_game only ignites via "fire:basic_flame", "default:lava_source", "default:lava_flowing") -- for some reason torch works already but permanent_flame does not |
|||
* Make gunpowder ignite via "building_blocks:Fireplace" |
|||
* Make TNT ignite via neighbors "throwing:arrow_fireworks_blue", "throwing:arrow_fireworks_red" |
|||
* Make "fire:flint_and_steel" item ignite TNT and gunpowder |
