This supersedes addChunkPacket() in most cases, and has a more clear name. It broadcasts the given packet to every player who has the target position within their chunk load radius.
This has the triple bonus effect of a) making a lot of code easier to read, b) reducing Server::getInstance() usages, and c) removing a whole bunch of Server dependencies.
The network and block namespaces are untouched by this commit due to potential for merge conflicts. These should be dealt with separately on master.
this is an absurd bug that nobody would ever otherwise notice, but the problem is that the doOnFireTick() call isn't evaluated if hasUpdate is already true.
PhpStorm can't see constructor usages when the class name is dynamic. This causes maintenance problems because cross-referencing constructors called like this doesn't show up dynamic calls.
it's no longer necessary to force-write these, since the NBT is now ephemeral. Any tag type mismatches should be dealt with on read, after which the original tag will be discarded anyway.
I considered renaming sendDataPacket() to dataPacket() to reduce the BC breaks, but the parameter set has changed, which might cause astonishing behaviour, so it's better to break it in a loud way. Also, this has a clearer name.
this was an interesting bug.
This was discovered by making a projectile's drag 0, making its gravity a factor of its throw force (such that force / gravity = integer value), and then throwing it directly up. At the apex, an error would occur due to trying to do a ray trace with a zero vector.
This also led me to realize that there's an edge case in the current movement system - if an entity's motion reaches 0, it will stop getting movement updates. This can be undesirable when things such as gravity cause motion to become zero when throwing a projectile directly upwards. This will need to be fixed separately.
