Subject: [PATCH] Add Alternate Current redstone implementation

|
|
|
||
|
|
This patch adds Alternate Current's redstone implementation as an alternative to vanilla and Eigencraft's.
|
||
|
|
Performance of (de)powering redstone dust is many times faster than vanilla, and even exceeds Eigencraft.
|
||
|
|
Similar to Eigencraft, Alternate Current heavily changes the update order of redstone dust. This means any contraption that
|
||
|
|
is location dependent in vanilla will either work everywhere or nowhere when using Alternate Current/Eigencraft. Beyond that
|
||
|
|
parity issues should be rare for both implementations, though Alternate Current has not been tested as thoroughly, so I
|
||
|
|
cannot comment on how the two compare in that aspect.
|
||
|
|
|
||
|
|
Alternate Current is more invasive than Eigencraft, though some of the modifications can be removed with only a minor
|
||
|
|
performance penalty in a small number of cases. Alternate Current needs the following modifications:
|
||
|
|
* Level/ServerLevel: Each level has its own 'wire handler' that handles redstone dust power changes.
|
||
|
|
* RedStoneWireBlock: Replace calls to vanilla's or Eigencraft's methods for handling power changes with calls to
|
||
|
|
Alternate Current's wire handler.
|
||
|
|
* (optional) Every power emitter's block class: new methods added to these classes make it easier for Alternate Current
|
||
|
|
to check if any block is a potential power source.
|
||
|
|
|
||
|
|
The use-faster-eigencraft-redstone config has been replaced with the redstone-implementation config, which can be used to
|
||
|
|
switch between the vanilla, Eigencraft, and Alternate Current implementations.

+/**
|
||
|
|
+ * This class handles power changes for redstone wire. The algorithm was
|
||
|
|
+ * designed with the following goals in mind:
|
||
|
|
+ * <br>
|
||
|
|
+ * 1. Minimize the number of times a wire checks its surroundings to determine
|
||
|
|
+ * its power level.
|
||
|
|
+ * <br>
|
||
|
|
+ * 2. Minimize the number of block and shape updates emitted.
|
||
|
|
+ * <br>
|
||
|
|
+ * 3. Emit block and shape updates in a deterministic, non-locational order,
|
||
|
|
+ * fixing bug MC-11193.
|
||
|
|
+ *
|
||
|
|
+ * <p>
|
||
|
|
+ * In Vanilla redstone wire is laggy because it fails on points 1 and 2.
|
||
|
|
+ *
|
||
|
|
+ * <p>
|
||
|
|
+ * Redstone wire updates recursively and each wire calculates its power level in
|
||
|
|
+ * isolation rather than in the context of the network it is a part of. This
|
||
|
|
+ * means a wire in a grid can change its power level over half a dozen times
|
||
|
|
+ * before settling on its final value. This problem used to be worse in 1.13 and
|
||
|
|
+ * below, where a wire would only decrease its power level by 1 at a time.
|
||
|
|
+ *
|
||
|
|
+ * <p>
|
||
|
|
+ * In addition to this, a wire emits 42 block updates and up to 22 shape updates
|
||
|
|
+ * each time it changes its power level.
|
||
|
|
+ *
|
||
|
|
+ * <p>
|
||
|
|
+ * Of those 42 block updates, 6 are to itself, which are thus not only
|
||
|
|
+ * redundant, but a big source of lag, since those cause the wire to
|
||
|
|
+ * unnecessarily re-calculate its power level. A block only has 24 neighbors
|
||
|
|
+ * within a Manhattan distance of 2, meaning 12 of the remaining 36 block
|
||
|
|
+ * updates are duplicates and thus also redundant.
|
||
|
|
+ *
|
||
|
|
+ * <p>
|
||
|
|
+ * Of the 22 shape updates, only 6 are strictly necessary. The other 16 are sent
|
||
|
|
+ * to blocks diagonally above and below. These are necessary if a wire changes
|
||
|
|
+ * its connections, but not when it changes its power level.
|
||
|
|
+ *
|
||
|
|
+ * <p>
|
||
|
|
+ * Redstone wire in Vanilla also fails on point 3, though this is more of a
|
||
|
|
+ * quality-of-life issue than a lag issue. The recursive nature in which it
|
||
|
|
+ * updates, combined with the location-dependent order in which each wire
|
||
|
|
+ * updates its neighbors, makes the order in which neighbors of a wire network
|
||
|
|
+ * are updated incredibly inconsistent and seemingly random.
|
||
|
|
+ *
|
||
|
|
+ * <p>
|
||
|
|
+ * Alternate Current fixes each of these problems as follows.
|
||
|
|
+ *
|
||
|
|
+ * <p>
|
||
|
|
+ * 1. To make sure a wire calculates its power level as little as possible, we
|
||
|
|
+ * remove the recursive nature in which redstone wire updates in Vanilla.
|
||
|
|
+ * Instead, we build a network of connected wires, find those wires that receive
|
||
|
|
+ * redstone power from "outside" the network, and spread the power from there.
|
||
|
|
+ * This has a few advantages:
|
||
|
|
+ * <br>
|
||
|
|
+ * - Each wire checks for power from non-wire components just once, and from
|
||
|
|
+ * nearby wires just twice.
|
||
|
|
+ * <br>
|
||
|
|
+ * - Each wire only sets its power level in the world once. This is important,
|
||
|
|
+ * because calls to Level.setBlock are even more expensive than calls to
|
||
|
|
+ * Level.getBlockState.
|
||
|
|
+ *
|
||
|
|
+ * <p>
|
||
|
|
+ * 2. There are 2 obvious ways in which we can reduce the number of block and
|
||
|
|
+ * shape updates.
|
||
|
|
+ * <br>
|
||
|
|
+ * - Get rid of the 18 redundant block updates and 16 redundant shape updates,
|
||
|
|
+ * so each wire only emits 24 block updates and 6 shape updates whenever it
|
||
|
|
+ * changes its power level.
|
||
|
|
+ * <br>
|
||
|
|
+ * - Only emit block updates and shape updates once a wire reaches its final
|
||
|
|
+ * power level, rather than at each intermediary stage.
|
||
|
|
+ * <br>
|
||
|
|
+ * For an individual wire, these two optimizations are the best you can do, but
|
||
|
|
+ * for an entire grid, you can do better!
|
||
|
|
+ *
|
||
|
|
+ * <p>
|
||
|
|
+ * Since we calculate the power of the entire network, sending block and shape
|
||
|
|
+ * updates to the wires in it is redundant. Removing those updates can reduce
|
||
|
|
+ * the number of block and shape updates by up to 20%.
|
||
|
|
+ *
|
||
|
|
+ * <p>
|
||
|
|
+ * 3. To make the order of block updates to neighbors of a network
|
||
|
|
+ * deterministic, the first thing we must do is to replace the location-
|
||
|
|
+ * dependent order in which a wire updates its neighbors. Instead, we base it on
|
||
|
|
+ * the direction of power flow. This part of the algorithm was heavily inspired
|
||
|
|
+ * by theosib's 'RedstoneWireTurbo', which you can read more about in theosib's
|
||
|
|
+ * comment on Mojira <a href="https://bugs.mojang.com/browse/MC-81098?focusedCommentId=420777&page=com.atlassian.jira.plugin.system.issuetabpanels%3Acomment-tabpanel#comment-420777">here</a>
|
||
|
|
+ * or by checking out its implementation in carpet mod <a href="https://github.com/gnembon/fabric-carpet/blob/master/src/main/java/carpet/helpers/RedstoneWireTurbo.java">here</a>.
|
||
|
|
+ *
|
||
|
|
+ * <p>
|
||
|
|
+ * The idea is to determine the direction of power flow through a wire based on
|
||
|
|
+ * the power it receives from neighboring wires. For example, if the only power
|
||
|
|
+ * a wire receives is from a neighboring wire to its west, it can be said that
|
||
|
|
+ * the direction of power flow through the wire is east.
|
||
|
|
+ *
|
||
|
|
+ * <p>
|
||
|
|
+ * We make the order of block updates to neighbors of a wire depend on what is
|
||
|
|
+ * determined to be the direction of power flow. This not only removes
|
||
|
|
+ * locationality entirely, it even removes directionality in a large number of
|
||
|
|
+ * cases. Unlike in 'RedstoneWireTurbo', however, I have decided to keep a
|
||
|
|
+ * directional element in ambiguous cases, rather than to introduce randomness,
|
||
|
|
+ * though this is trivial to change.
|
||
|
|
+ *
|
||
|
|
+ * <p>
|
||
|
|
+ * While this change fixes the block update order of individual wires, we must
|
||
|
|
+ * still address the overall block update order of a network. This turns out to
|
||
|
|
+ * be a simple fix, because of a change we made earlier: we search through the
|
||
|
|
+ * network for wires that receive power from outside it, and spread the power
|
||
|
|
+ * from there. If we make each wire transmit its power to neighboring wires in
|
||
|
|
+ * an order dependent on the direction of power flow, we end up with a
|
||
|
|
+ * non-locational and largely non-directional wire update order.

||
|
|
+ * receive power at multiple points. Consider the following setup:
|
||
|
|
+ *
|
||
|
|
+ * <p>
|
||
|
|
+ * (top-down view, W = wire, L = lever, _ = air/other)
|
||
|
|
+ * <br> {@code _ _ W _ _ }
|
||
|
|
+ * <br> {@code _ W W W _ }
|
||
|
|
+ * <br> {@code W W L W W }
|
||
|
|
+ * <br> {@code _ W W W _ }
|
||
|
|
+ * <br> {@code _ _ W _ _ }
|
||
|
|
+ *
|
||
|
|
+ * <p>
|
||
|
|
+ * The lever powers four wires in the network at once. If this is identified
|
||
|
|
+ * correctly, the entire network can (un)power at once. While it is not
|
||
|
|
+ * practical to cover every possible situation where a network is (un)powered
|
||
|
|
+ * from multiple points at once, checking for common cases like the one
|
||
|
|
+ * described above is relatively straight-forward.
|
||
|
|
+ *
|
||
|
|
+ * <p>
|
||
|
|
+ * While these extra checks can provide significant performance gains in some
|
||
|
|
+ * cases, in the majority of cases they will have little to no effect, but do
|
||
|
|
+ * require extra code modifications to all redstone power emitters. Removing
|
||
|
|
+ * these optimizations would limit code modifications to the RedStoneWireBlock
|
||
|
|
+ * and ServerLevel classes while leaving the performance mostly intact.
