From aa283efeb188971e7edc2b45cf90cd871c4b9fe9 Mon Sep 17 00:00:00 2001 From: Claude Date: Thu, 8 Jan 2026 16:28:07 +0000 Subject: [PATCH 01/36] feat: add core data structures for double battles support Milestone 1 of doubles refactor: - Add GameMode enum (Singles, Doubles) - Extend BattleData with slotSwitchFlagsAndGameMode (packed uint8) - Add p0Move2, p1Move2 to BattleConfig for slot 1 moves - Add constants for activeMonIndex 4-bit packing and switch flags - Update Engine startBattle to initialize doubles fields - Update getBattleContext/getCommitContext to extract game mode - Add gameMode field to Battle, ProposedBattle structs - Update matchmaker and CPU to pass gameMode - Update all tests with gameMode: GameMode.Singles All changes are backwards compatible - singles mode works unchanged. --- src/Constants.sol | 25 +++++++++++++++- src/Engine.sol | 42 ++++++++++++++++++++++++--- src/Enums.sol | 5 ++++ src/Structs.sol | 43 +++++++++++++++++++++++----- src/cpu/CPU.sol | 5 ++-- src/matchmaker/DefaultMatchmaker.sol | 10 +++++-- test/BattleHistoryTest.sol | 3 +- test/CPUTest.sol | 27 +++++++++++------ test/EngineTest.sol | 3 +- test/MatchmakerTest.sol | 36 +++++++++++++++-------- test/abstract/BattleHelper.sol | 4 ++- 11 files changed, 163 insertions(+), 40 deletions(-) diff --git a/src/Constants.sol b/src/Constants.sol index aebe9302..262e4e8c 100644 --- a/src/Constants.sol +++ b/src/Constants.sol @@ -42,4 +42,27 @@ uint256 constant EFFECT_COUNT_MASK = 0x3F; // 6 bits = max count of 63 address constant TOMBSTONE_ADDRESS = address(0xdead); -uint256 constant MAX_BATTLE_DURATION = 1 hours; \ No newline at end of file +uint256 constant MAX_BATTLE_DURATION = 1 hours; + +// Active mon index packing (uint16): +// Singles: lower 8 bits = p0 active, upper 8 bits = p1 active (backwards compatible) +// Doubles: 4 bits per slot (supports up to 16 mons per team) +// Bits 0-3: p0 slot 0 active mon index +// Bits 4-7: p0 slot 1 active mon index +// Bits 8-11: p1 slot 0 active mon index +// Bits 12-15: p1 slot 1 active mon index +uint8 constant ACTIVE_MON_INDEX_BITS = 4; +uint8 constant ACTIVE_MON_INDEX_MASK = 0x0F; // 4 bits + +// Slot switch flags + game mode packing (uint8): +// Bit 0: p0 slot 0 needs switch +// Bit 1: p0 slot 1 needs switch +// Bit 2: p1 slot 0 needs switch +// Bit 3: p1 slot 1 needs switch +// Bit 4: game mode (0 = singles, 1 = doubles) +uint8 constant SWITCH_FLAG_P0_SLOT0 = 0x01; +uint8 constant SWITCH_FLAG_P0_SLOT1 = 0x02; +uint8 constant SWITCH_FLAG_P1_SLOT0 = 0x04; +uint8 constant SWITCH_FLAG_P1_SLOT1 = 0x08; +uint8 constant SWITCH_FLAGS_MASK = 0x0F; +uint8 constant GAME_MODE_BIT = 0x10; // Bit 4: 0 = singles, 1 = doubles \ No newline at end of file diff --git a/src/Engine.sol b/src/Engine.sol index 0f340ced..66884065 100644 --- a/src/Engine.sol +++ b/src/Engine.sol @@ -177,14 +177,24 @@ contract Engine is IEngine, MappingAllocator { config.koBitmaps = 0; // Store the battle data with initial state + // For doubles: activeMonIndex packs 4 slots (p0s0=0, p0s1=1, p1s0=0, p1s1=1) + // For singles: only lower 8 bits used (p0=0, p1=0) + uint16 initialActiveMonIndex = battle.gameMode == GameMode.Doubles + ? uint16(0) | (uint16(1) << 4) | (uint16(0) << 8) | (uint16(1) << 12) // p0s0=0, p0s1=1, p1s0=0, p1s1=1 + : uint16(0); // Singles: both players start with mon 0 + + // Pack game mode into slotSwitchFlagsAndGameMode (bit 4 = game mode) + uint8 slotSwitchFlagsAndGameMode = battle.gameMode == GameMode.Doubles ?

Added validatePlayerMoveForSlotWithClaimed to IValidator to account for what the other slot is switching to when validating moves. This allows slot 1 to NO_OP when slot 0 is claiming the last available reserve, rather than incorrectly rejecting the NO_OP because the validator didn't account for the pending switch. Also adds tests verifying: - Both slots can't switch to same mon (reverts) - KO'd mon's moves don't execute - Both opponent slots KO'd mid-turn handled correctly --- snapshots/EngineGasTest.json | 28 ++-- snapshots/MatchmakerTest.json | 6 +- src/DefaultValidator.sol | 92 +++++++++++++ src/DoublesCommitManager.sol | 22 ++- src/IValidator.sol | 11 ++ test/DoublesValidationTest.sol | 242 ++++++++++++++++++++++++++++++++- 6 files changed, 375 insertions(+), 26 deletions(-) diff --git a/snapshots/EngineGasTest.json b/snapshots/EngineGasTest.json index 721efcef..d1f37590 100644 --- a/snapshots/EngineGasTest.json +++ b/snapshots/EngineGasTest.json @@ -1,17 +1,17 @@ { - "B1_Execute": "1003703", - "B1_Setup": "817752", - "B2_Execute": "778056", - "B2_Setup": "283130", - "Battle1_Execute": "505822", - "Battle1_Setup": "794141", - "Battle2_Execute": "420512", - "Battle2_Setup": "237842", - "FirstBattle": "3583299", + "B1_Execute": "1005029", + "B1_Setup": "817796", + "B2_Execute": "779391", + "B2_Setup": "283174", + "Battle1_Execute": "506277", + "Battle1_Setup": "794185", + "Battle2_Execute": "420967", + "Battle2_Setup": "237886", + "FirstBattle": "3589470", "Intermediary stuff": "43924", - "SecondBattle": "3692660", - "Setup 1": "1674199", - "Setup 2": "299218", - "Setup 3": "338942", - "ThirdBattle": "2994000" + "SecondBattle": "3699451", + "Setup 1": "1674243", + "Setup 2": "299262", + "Setup 3": "338986", + "ThirdBattle": "3000171" } \ No newline at end of file diff --git a/snapshots/MatchmakerTest.json b/snapshots/MatchmakerTest.json index 5ab01c1a..5819f6ea 100644 --- a/snapshots/MatchmakerTest.json +++ b/snapshots/MatchmakerTest.json @@ -1,5 +1,5 @@ { - "Accept1": "307847", - "Accept2": "34356", - "Propose1": "199515" + "Accept1": "307869", + "Accept2": "34378", + "Propose1": "199537" } \ No newline at end of file diff --git a/src/DefaultValidator.sol b/src/DefaultValidator.sol index 7d31332e..bf6d3145 100644 --- a/src/DefaultValidator.sol +++ b/src/DefaultValidator.sol @@ -362,6 +362,98 @@ contract DefaultValidator is IValidator { return true;

The validator doesn't receive `slotIndex`, so it always uses `ctx.p0ActiveMonIndex` (slot 0 only). + +**Fix:** Add `slotIndex` parameter to `validateSpecificMoveSelection` and use it to check the correct mon. + +#### Issue #3: AfterDamage Effects Run on Wrong Mon (HIGH) +**Location:** `dealDamage` + +**Problem:** After damage is dealt to a specific mon, AfterDamage effects run on slot 0's mon instead of the damaged mon.

This is because `_runEffects` defaults to slot 0 when no explicit monIndex is provided. - -**Fix:** Pass explicit monIndex to switch effect execution calls. - -#### Issue #2: Move Validation Uses Wrong Mon (CRITICAL) -**Location:** `_handleMoveForSlot`, `DefaultValidator.validateSpecificMoveSelection` - -**Problem:** During move execution validation in doubles, stamina and validity are checked against slot 0's mon instead of the actual attacker. The validator doesn't receive `slotIndex`, so it always uses `ctx.p0ActiveMonIndex` (slot 0 only). - -**Fix:** Add `slotIndex` parameter to `validateSpecificMoveSelection` and use it to check the correct mon. - -#### Issue #3: AfterDamage Effects Run on Wrong Mon (HIGH) -**Location:** `dealDamage` - -**Problem:** After damage is dealt to a specific mon, AfterDamage effects run on slot 0's mon instead of the damaged mon. The function receives explicit `monIndex` but doesn't pass it to effect execution. - -**Fix:** Pass explicit monIndex to AfterDamage effect execution. - -#### Issue #4: OnUpdateMonState Effects Run on Wrong Mon (HIGH) -**Location:** `updateMonState` - -**Problem:** When a mon's state changes, OnUpdateMonState effects run on slot 0's mon instead of the affected mon. Similar to issue #3, the function has the monIndex but doesn't pass it. - -**Fix:** Pass explicit monIndex to OnUpdateMonState effect execution. - -#### Root Cause -The effect execution system (`_runEffects`) uses `playerIndex` only and defaults to slot 0, but the move/switch execution system properly tracks `slotIndex`. The `_runEffectsForMon` function was added to accept explicit monIndex but wasn't being used in critical paths. - -#### Tests Added -- Switch-in/out effect tests with mock effect -- AfterDamage effect tests (heal on damage mock) -- Validation that effects run on correct mon in both slots - ---- - -### Known Inconsistencies (Future Work) - -#### Singles vs Doubles Execution Patterns -- **Singles**: `DefaultCommitManager.revealMove` calls `ENGINE.execute(battleKey)` directly -- **Doubles**: `DoublesCommitManager.revealMoves` calls `ENGINE.setMoveForSlot` for each slot, then `ENGINE.execute(battleKey)` -- Consider unifying the pattern if performance permits - -#### NO_OP Handling During Single-Player Switch Turns -- In doubles, when only one player needs to switch (one slot KO'd), the other slot can attack -- The non-switching slot should technically be able to submit `NO_OP`, but current validation only strictly requires `NO_OP` when no valid switch targets exist -- This is working correctly but the semantics could be clearer - -#### Error Naming -- `DefaultCommitManager.InvalidMove(address player)` vs `DoublesCommitManager.InvalidMove(address player, uint256 slotIndex)` -- Different signatures for same conceptual error - could be unified with optional slot parameter +- Abilities affecting both slots (e.g., Intimidate) +- Weather/terrain affecting 4 mons +- Spread moves hitting multiple targets + +#### Execution Pattern Unification +- Singles: `revealMove` → `execute` directly +- Doubles: `revealMoves` → `setMoveForSlot` × 2 → `execute` +- Consider unifying if performance permits + +#### Slot Information in Move Interface +- `IMoveSet.move()` doesn't receive attacker's slot index +- Limits slot-aware move logic in doubles From 0b62da7f5b3d323ddfe6fac89f2f37363b02717e Mon Sep 17 00:00:00 2001 From: Claude Date: Fri, 16 Jan 2026 18:04:33 +0000 Subject: [PATCH 31/36] refactor: rename activeMonIndex fields to use 0-indexed notation MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit - p0ActiveMonIndex → p0ActiveMonIndex0 - p1ActiveMonIndex → p1ActiveMonIndex0 - p0ActiveMonIndex2 → p0ActiveMonIndex1 - p1ActiveMonIndex2 → p1ActiveMonIndex1 This maintains consistent 0-indexed naming across the codebase. --- CHANGELOG.md | 2 +- src/DefaultValidator.sol | 12 ++++++------ src/Engine.sol | 8 ++++---- src/Structs.sol | 8 ++++---- 4 files changed, 15 insertions(+), 15 deletions(-) diff --git a/CHANGELOG.md b/CHANGELOG.md index 430cec72..ae5ba037 100644 --- a/CHANGELOG.md +++ b/CHANGELOG.md @@ -14,7 +14,7 @@ This document summarizes all changes made to implement double battles support. #### `src/Structs.sol` - **`BattleArgs`** and **`Battle`**: Added `GameMode gameMode` field - **`BattleData`**: Added `slotSwitchFlagsAndGameMode` (packed field: lower 4 bits = per-slot switch flags, bit 4 = game mode) -- **`BattleContext`** / **`BattleConfigView`**: Added `p0ActiveMonIndex2`, `p1ActiveMonIndex2`, `slotSwitchFlags`, `gameMode` +- **`BattleContext`** / **`BattleConfigView`**: Added `p0ActiveMonIndex0`, `p0ActiveMonIndex1`, `p1ActiveMonIndex0`, `p1ActiveMonIndex1`, `slotSwitchFlags`, `gameMode` #### `src/Constants.sol` - Added `GAME_MODE_BIT`, `SWITCH_FLAGS_MASK`, `ACTIVE_MON_INDEX_MASK` for packed storage diff --git a/src/DefaultValidator.sol b/src/DefaultValidator.sol index 00462272..7be20d88 100644 --- a/src/DefaultValidator.sol +++ b/src/DefaultValidator.sol @@ -85,7 +85,7 @@ contract DefaultValidator is IValidator { returns (bool) { BattleContext memory ctx = ENGINE.getBattleContext(battleKey); - uint256 activeMonIndex = (playerIndex == 0) ?
