TNT-Tracker

The tracker records the exact flight path of multiple TNT entities, draws their trails in 3D and counts the blocks each shot destroys. Ignited TNT is marked with glowing red boxes in real time, and recorded positions appear as small colored hitboxes, with explosion points shown as white boxes during replay. After a shot, whole salvos can be replayed at an adjustable speed, so a cannon can be tested without destroying single blocks each time.

Trails can be drawn as a plain line, as dots for a more technical view, as smooth connecting lines, or as axis-aligned steps. Movement on each axis can be shown separately in red, green and blue. Tick labels give the exact time, written as T+ plus the tick, and group the TNT of one salvo together, which helps when comparing cannon settings. Cannon shots can be run without damage, and the interface text is configurable and multilingual.

The mod is for redstone builders and engineers who tune TNT cannons by hand. It is published for Fabric only, for 1.20.4. Either side can run it, and neither needs it, so a single player or a server can use it. The code is open source under the MIT License.
