pathetic's Introduction

Pathetic

Pathetic is a simple and intuitive backwards-compatible up-to-date pathfinding API for Spigot and forks. See more info here: https://www.spigotmc.org/threads/how-pathetic.578998/#post-4644823

Both start and stop are < 30 blocks apart and start is the players current position.

It doesn't matter if both blocks are air or set.

It seems to me the FailingSnapshotManager never retrieves chunk snapshots instead of only if they are loaded (as I would expect from the description in the JavaDoc https://patheticdocs.ollieee.xyz/org/patheloper/api/pathing/rules/PathingRuleSet.html)

(And just out of curiosity, why is NMS used to retrieve the ChunkSnapshots and not the Bukkit API?)

ChunkSnapshot in SnapshotManager is not thread safe.

Whenever the fetchAndGetBlock method is used multiple times at once, it causes errors.
Thanks for the project by the way, this was tremendously helpful.

fix diagonal offset behaviour

allowingDiagonal is skipping blocks which therefore can't be processed by the strategy. means a path can go through walls ignoring the strategy etc.

Non Walkable Path Finding

I would like to use this project for path finding air targets how do I do this

The FailingSnapshotManager leaks memory

The cached chunks in the FailingSnapshotManager.SNAPSHOTS_MAP are only invalidated on block changes but otherwise never discarded.

If a player wanders around the world with constant path finding a lot of ChunkSnapshots accumulate and are never discarded.

Problem with install

Mapping was not publish to maven

Trying to use this on 1.19.4 and your mapping is not published for version 2.1.1, only the api is listed but I need the mapping version

Simplifying the path finding result

I was wondering if it was possible that when a path is moving in a straight line, if there could be an option for a 'simple' version. IE: if Point A, Point B, Point C, Point D all go in the same direction diagonal, we don't really need point B / C if we are trying to use velocity to move an object, we only need a and d, so is is possible to have an option that only gives us A/D?

Block state / Material access

Is your feature request related to a problem?

It's not really possible to check for block states when checking for blocks in the pathfinding strategy (e.g. pathfind only on trapdoors if they are closed)

Describe the solution you'd like.

Having access to the block state or at least the material of the block in PathBlock

Describe alternatives you've considered.

Querying the block myself. But I think that would be pretty inefficient.

Other

There is probably a reason this doesn't exist. I haven't looked into how pathetic is built, but maybe it is because of performance memory management reasons. However, without this, implementing more complex strategies is not really possible.
