This enables battles in tests to reset their RNG to what it originally
was when they were created. A number of tests do this already by
breaking encapsulating and modifying the prng variable directly. This
should fix that.
We also remove createBattleWithPRNG and min/maxSeed properties.
Firstly, the tests that were still using the maxSeed property were
setting it to Battle.seed which has no effect since the PRNG class does
not look at this property any more - so these were no-ops.
After removing this property from tests, maxRollSeed was never used, so
I removed it and renamed minRollSeed to DEFAULT_ROLL_SEED (since it's
constant).
The places that were still using minRollSeed also were no-ops or were
using createBattleWithPRNG. Since every single instance was actually
just using the same code, I removed createBattleWithPRNG and made
createBattle default to giving you a seed with DEFAULT_ROLL_SEED and
removed the minRollSeed property too.
This makes tests much simpler and reduces the usage surface of
TestTools; now, you must define your *own* seed if you're making a PRNG
for a test, or you use one that TestTools gives you; you may not use a
public property that TestTools gives you.
We also remove the code that removes a listener in the Battle Engine.

This removes the 'deterministic test' tools by preventing action at a
distance (namely, preventing the modification of the `init` method in
`Battle` during tests). This action at a distance is incredibly
confusing.
All this action at a distance did was discard any parameters that were
passed to `Battle` that weren't the first three (which was probably a
mistake by the original author) and also hard code `this.seed` and
`this.startingSeed` in `Battle`.
This functionality has now been moved to the `PRNG` class, so instead
users should pass a `PRNG` to `Battle` as the 5th constructor argument.
Users can also pass one as the third argument to `common.createBattle`
or use `common.createBattleWithPRNG` with the PRNG as the first
argument.
The PRNG is just an encapsulation of the pseudo-random algorithm in a
class. It is stateful, so make sure to take a `clone()` of the PRNG if
you want to re-use it.
This makes gen 7 the default mod, updates the tests to match, and fixes
the corresponding build error.
Note that this only changes the default Tools mod, the default Formats
mod is now gen6. gen7 must be specified by name in a format, for that
format to be a gen 7 format.
Sometimes mods would mess up if they were loaded in the wrong order.
Specifically, some autogenerated properties of e.g. moves need to be
recalculated for mods.
Anyway, the entire cache system is replaced with a newer, faster,
slightly-more-memory-intensive-but-only-slightly cache system, which
no longer has these kinds of loading order issues.
The following functions have been renamed:
- Tools.html to CommandParser.html
- Tools.plural to CommandParser.plural
- Tools.escapeHTML to CommandParser.escapeHTML
- Tools.toDurationString to CommandParser.toDurationString
- Tools.toTimeStamp to CommandParser.toTimestamp
(notice the lowercase 's')
This is in preparation for a rename of Tools to Dex (by removing the
non-dex-related functions) and a rename of CommandParser to either
Messages or Chat.
Updated remaining Primal Weathers to the new APIs.
Updated misleading test cases relating to base power of moves in
Desolate Land / Primordial Sea.
Increased coverage on weather tests.
- Implements `skip` choice, which acts as a placeholder in the player
choices. This is relevant to double-KOs, since in-game you are allowed
to specify switch-ins in any order.
Among the added tests, are included:
- A skipped test for an edge case in which usage of Reflect Type
causes a typing information leak via the presence/absence of the
"maybe-trapped" warning and cancel prevention.
- Two skipped tests related to partial decisions functionality.
- Basically, support is added only for `move` requests here, and
behind a flag (`battle.supportsPartialDecision`).
- Switching is mostly supported, except for the multiple-KOs case.
- Team Preview needs a rework in order to enable this feature.
Among the newly added rules, there are quite a few intended to enforce
compliance of CONTRIBUTING.md-blessed idioms, as well as ensure
safe usage of classes and constant bindings.
We are also now enforcing usage of early return in commands.js,
which has 100% compliance as of fd2c45c.
Now that nodejs/node#3072 is mostly fixed, we can finally start using
Node 4+ features.
This refactor:
- uses arrow functions where appropriate
Note that arrow functions still aren't used in Mocha, where `this`
is sometimes meaningful.
This also removes the need for .bind() nearly everywhere, as well
as the `self = this` trick.
- refactors Validator and Connection into ES6 classes
- no longer uses Array#forEach for iterating arrays
We strongly prefer for (let i = 0; i < arr.length; i++) because of
performance reasons. Most forEaches have been replaced with for..of,
though, which is 5x slower than the long-form loop but 2x faster
than forEach, which is good enough outside of most inner loops.
The only exception is tournaments, which is due for a more invasive
refactor soon anyway.
Previously moves like Leech Seed incremented residualdmg when used by 1,
but this doesn't actually happen in the game. Instead, an actual game
uses a flag to store toxic poisoning flag, and when it's not specified,
these statuses always dealt 1/16 of full HP.
This fixes the issue where the sequence of moves (Toxic followed by Leech
Seed) was dealing 1/16, 3/16, and 4/16 of full HP in residual damage,
instead of 1/16, 2/16, and 3/16.
Steel-types are immune to the poison status in Gen 3+, so wrap it into the
"fail when the opposing Pokemon is immune to the status it sets" and set
up the poison-inflicting status test to check Generation 2.
Spin off Thunder Wave to its own test, and also create a test for Glare to
check its Generation 3 behavior as well.
- Streams are merged to make sure that all errors and warnings are reported.
- Adds dev dependencies: `merge-stream` and `lazypipe`.
- Tracks a fork of `gulp-jshint` to fix https://github.com/spalger/gulp-jshint/issues/88
