📝 Walkthrough

Walkthrough

Adds ObjectiveGroup to track objective completion and failure results. The class supports required-objective thresholds, duplicate validation, removal, delayed completion callbacks, and manual results. The changelog records the objective logic update.

Changes

Objective group lifecycle

Layer / File(s) Summary
Group contract and initialization
lua/sim/objectives/ObjectiveGroup.lua
Defines the ObjectiveGroup class, callback type, state fields, generated names, and constructor inputs.
Objective tracking and result evaluation
lua/sim/objectives/ObjectiveGroup.lua
Adds activity validation, objective registration, duplicate checks, result counting, threshold evaluation, and objective removal.
Completion handling and changelog
lua/sim/objectives/ObjectiveGroup.lua, changelog/snippets/other.7273.md
Deactivates completed groups, delays the completion callback, adds ManualResult, and records the objective logic changes.

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

Merge Risk: 🟡 Moderate · up to 64360

Objective groups can remain unresolved after an objective is removed even when the remaining successful objectives satisfy the group requirement, preventing expected mission completion behavior. This should be corrected before merge.

Detach the objective callback before removal.

At Line 109, RemoveObjective clears only the tracking entry. AddObjective has already installed an anonymous result callback. If an active objective is removed and then re-added before it finishes, both callbacks remain registered. One result can increment NumCompleted twice. With numRequired = 2, the group can complete after one objective result. (raw.githubusercontent.com)

Store the callback per objective and call objective:RemoveResultCallback(...) before clearing self.Objectives[objective.Tag].

Re-evaluate the group after removal.

When NumRequired is omitted, removal changes the required count. For example, if one of two objectives succeeds and RemoveObjective removes the remaining objective, NumCompleted equals the new required count. The group stays active because Line 113 does not run the completion checks. The removed objective cannot settle the group later because it is no longer tracked.

Extract the result checks from OnObjectiveResult into a helper. Call that helper after this deletion.
