Summary

  • capture the selected quest, current step, and custom quest handler once per QuestScript scheduler tick
  • make separate graphics callbacks and Misthalin custom logic tolerate a cleared selection
  • add structural regressions preventing repeated mutable selection/current-step reads
  • bump Quest Helper to 1.0.14

Verification

  • Quest Helper test suite: PASS
  • :client:runClientThreadScanner: PASS
  • :client:check: PASS
  • independent Java review: APPROVED

Summary by CodeRabbit

  • Bug Fixes

    • Ensured quest progress, custom logic, animations, and dialogue handling consistently use the active quest and step.
  • Tests
    • Added coverage for safe quest selection and consistent quest-step handling during scheduler updates.
  • Chores
    • Updated the Quest Helper plugin version to 1.0.14.

📝 Walkthrough

Walkthrough

QuestScript now snapshots selected quest state once per execution cycle, resolves quest-specific logic centrally, and passes cached state through custom logic and step dispatch. MisthalinMystery handles missing quest state safely. Lifecycle tests verify read centralization and snapshot behavior.

Quest state lifecycle

Layer / File(s) Summary
Quest execution snapshots
runelite-client/src/main/java/net/runelite/client/plugins/microbot/questhelper/QuestScript.java, runelite-client/src/main/java/net/runelite/client/plugins/microbot/questhelper/QuestHelperPlugin.java, runelite-client/src/test/java/net/runelite/client/plugins/microbot/questhelper/QuestCustomLogicLifecycleTest.java
QuestScript captures selected quest and current step state, resolves IQuest logic, and uses cached values for custom logic and step dispatch. The plugin descriptor version changes to 1.0.14. Tests verify centralized selected-quest reads and scheduler snapshots.
Quest-specific null-safe logic
runelite-client/src/main/java/net/runelite/client/plugins/microbot/questhelper/logic/MisthalinMystery.java
MisthalinMystery caches selected quest and current step state. Custom logic, animation handling, and active-step checks return safely when required state is missing.

Estimated code review effort: 3 (Moderate) | ~20 minutes

Merge Risk: 🟡 Moderate · up to e0f76

Quest selection changes can cause custom quest behavior or animation gating to run against the wrong quest step. Pass the per-tick snapshot into custom logic and cover the selection-change case before merging.

🎯 Functional Correctness | 🟠 Major | 🏗️ Heavy lift

Pass the scheduler snapshot into custom quest logic.

QuestScript resolves questLogic from one selection, but MisthalinMystery reads the mutable selection again. If the selection changes between these reads, the handler for the prior quest can run against the new quest's current step. The animation gate can also use the new quest's step.

Pass an immutable per-tick quest context, or the cached active step, to IQuest.executeCustomLogic and IQuest.customLogicRunsWhileAnimating. Add a regression test where the plugin returns quest A during handler resolution and quest B during custom logic.

  • runelite-client/src/main/java/net/runelite/client/plugins/microbot/questhelper/QuestScript.java#L1399-L1402: pass the scheduler-captured quest state to custom-logic methods.
  • runelite-client/src/main/java/net/runelite/client/plugins/microbot/questhelper/logic/MisthalinMystery.java#L87-L98: use the passed snapshot instead of reading QuestHelperPlugin again.
  • runelite-client/src/main/java/net/runelite/client/plugins/microbot/questhelper/logic/MisthalinMystery.java#L217-L223: use the same passed snapshot for animation gating.
