Subject: [PATCH] Lazily create LootContext for criterions
|
|
|
|
For each player on each tick, enter block triggers are invoked, and these create loot contexts that are promptly thrown away since the trigger doesn't pass the predicate
|
|
|
|
To avoid this, we now lazily create the LootContext if the criterion passes the predicate AND if any of the listener triggers require a loot context instance
|
