/explosionVisualizer fakeExplosions remove
/explosionVisualizer fakeExplosions removeall <-#remove all the fake explosions
/explosionVisualizer blockDamageRayRendererSettings range
/explosionVisualizer blockDamageRayRendererSettings range
: <Int(0~16)> : <Int(0~16)> : <Int(0~16)> : <Int(0~16)> : <Int(0~16)> : <Int(0~16)>
In Minecraft, 1532 rays are emitted from the center of the explosion towards the outermost layer of a 16x16x16 voxel grid surrounding the explosion center. (See" https://minecraft.fandom.com/wiki/Explosion" for details.)
Displaying them all together can look very cluttered. This command allows you to slice these rays for easier viewing.
: <Int(0~16)> : <Int(0~16)> : <Int(0~16)> : <Int(0~16)> : <Int(0~16)> : <Int(0~16)>
