Firstly, the old methods all routed to the CompletableFuture method. However, the CF method could not guarantee that if the caller was off-main that the future would be "completed" on-main. Since the callback methods used the CF one, this meant that the callback methods did not guarantee that the callbacks were to be called on the main thread. Now, all methods route to getChunkAtAsync(x, z, gen, urgent, cb) so that the methods with the callback are guaranteed to invoke the callback on the main thread. The CF behavior remains unchanged; it may still appear to complete on main if invoked off-main. Secondly, remove the scheduleOnMain invocation in the async chunk completion. This unnecessarily delays the callback by 1 tick. Thirdly, add getChunksAtAsync(minX, minZ, maxX, maxZ, ...) which will load chunks within an area. This method is provided as a helper as keeping all chunks loaded within an area can be complicated to implement for plugins (due to the lacking ticket API), and is already implemented internally anyways. Fourthly, remove the ticket addition that occured with getChunkAt and getChunkAtAsync. The ticket addition may delay the unloading of the chunk unnecessarily. It also fixes a very rare timing bug where the future/callback would be completed after the chunk unloads.

Subject: [PATCH] Fix arrows never despawning MC-125757
|
|
|
|
This forces the despawn counter to start ticking regardless of
|
|
state after the arrow has been alive for 200 ticks (10 seconds)
|
|
instead of getting stuck in a never despawn state (bubble columns,
|
|
etc).
