- Dropped "Add option to disable saving projectiles to disk" in favor of the above patch - Config migration is automatic. If "gameplay-mechanics.save-projectiles-to-disk" was set to false in purpur.yml, "projectile-load-save-per-chunk-limit" will be set to 0 in paper.yml (resulting in unchanged behaviour)

Subject: [PATCH] PaperPR - Projectile load/save limit per chunk
|
|
|
|
Adds a config option to limit the number of projectiles saved and loaded
|
|
to a chunk. Limits are counted per entity type, i.e. a limit of 5 means
|
|
that 5 arrows, 5 snowballs, 5 tridents, etc. will be allowed to be
|
|
saved/loaded per chunk. The default value of -1 disables the limit.
