Subject: [PATCH] Fix missing chunks due to integer overflow
|
|
|
|
This patch fixes a bug in the EndIslandDensityFunction class where the distance
|
|
from 0,0 squared overflows the maximum size of an integer. The overflow leads
|
|
to hard chunk borders around 370,000 blocks from 0,0. After this cutoff there
|
|
is a few hundred thousand block gap before end land resuming to generate at
|
|
530,000 blocks from spawn. This is due to the integer flipping back and forth.
|
|
|
|
The fix for the issue is quite simple, casting chunk coordinates to longs
|
|
allows the distance calculation to avoid overflow and work as intended.
|
|
|
|
This issue is being tracked in Mojira ticket MC-159283
