It's not a radius if you half it

You can create a random BlockPos directly from a u15

Should be configurable

To catch lag spikes, this should be a while loop, below it should subtract the tickRate instead of setting it to 0
Suggested change
| if (self.randomTicksTime >= tickrate) { | |
| while (self.randomTicksTime >= tickrate) { |

WIP
allows to create random particles like falling leaves and butterflies from flowers, or even sparkles from glowing stone blocks
