Fix#1501
I just added a condition check to not start a new pathfinder goal if the turtle already has one set.
Needs more testing.
This restores vanilla behavior of allowing placed chests to retain any Block Entity Tag data.
Upstream added filtering to chests, breaking vanilla behavior, and preventing use of loot table chests as a reward mechanism.
Upon review, we can find no security risk in allowing players to place a chest with NBT data, as Spawn Eggs, Minecarts, command blocks etc all have their own checks.
Additionally, survival mode players, non op players can not create these items anyways. If a player has Creative or Op, they already have high levels of access.
Plus, Chests aren't the only inventory that could have free form items, so this filter was insufficient anyways.
This method will return the Block a player is looking at while taking into consideration the AABB of each block in the path.
For example, you can look through the 1/4 space of air in a Stair block and get the block behind it instead of the Stair block you are looking past.
Replaces PR #1161 for 1.13
Resolves#930
Adds new slime pathfinder related events. All events can be cancelled.
- `SlimePathfindEvent` is the base event of all added events. Cancelling this event will cancel all pathfinders.
- `SlimeWanderEvent` is called when slimes wander around by either swimming or moving/jumping forward. Cancelling this event will prevent slimes from moving around and jumping, but they will still look around and target players.
- `SlimeSwimEvent`is called when slimes are swimming in water/lava. Cancelling will prevent the slimes from moving/jumping in water/lava.
- `SlimeChangeDirectionEvent` is called when a slime changes directions. It contains the new `yaw` position the slime wants to change to, and it can be set to another value. Cancelling this event will prevent slimes from changing directions (except for when targeting players).
- `SlimeTargetLivingEntityEvent` is called when a slime targets a player. NMS uses EntityLiving here so it is named this. Contains the LivingEntity the slime has targeted. Cancelling this event will prevent the slime from targeting the entity and will make it lose current focus.
Adds `Slime#canWander()` and `Slime#setWander(boolean)` for a more persistent control (does not persist server restarts) over all 4 pathfinder types without the spammy event having to be cancelled a bajillion times a second.
