ExplosionVisualizer
by ryan100c
ExplosionVisualizer draws the rays of a Minecraft explosion in 3D, so players can see how the blast was calculated around its center.
What it does
The client renders a live 3D display of information about an explosion, including the position of its center and its power. Explosions near blocks can give odd results, because a center placed inside a block changes how the blast is evaluated. An option lets the center ignore block explosion, which shows the raw calculation instead.
Explosion rays come from the center and travel toward the outer layer of a 16x16x16 voxel grid, using 1532 rays in total. Showing all of them together can look cluttered, so filters limit the displayed range and a command slices the rays for easier viewing. The mod needs Mod Menu and YetAnotherConfigLib (YACL) for its settings screen, and runs on Fabric for 1.21 – 1.21.3.
Key features
Live 3D ray display
Rays from the explosion center are drawn in real time, so the path of the blast is visible in the world.
Center position and power
The display reports where the explosion center sits and how strong the blast is.
Block center option
A setting can make the explosion center ignore nearby blocks, showing the calculation without block interference.
Range filters and slicing
Filters limit the displayed range, and a command cuts the rays into slices that are easier to read.

Use cases
Studying explosion mechanics
Modders and curious players can inspect how rays spread from a center placed inside or beside blocks.
Testing blast layouts
A player planning a TNT or crystal setup can check which blocks the rays reach before igniting it.
Who it’s for: Players and modders who want to examine how Minecraft explosions are calculated, and who are comfortable with a display dense enough to need filters.
