Summary of Changes
Hello @CitralFlo, I'm Gemini Code Assist1! I'm currently reviewing this pull request and will post my feedback shortly. In the meantime, here's a summary to help you and other reviewers quickly get up to speed!
This pull request addresses a potential logical error in how the highest priority WorldGuard region is identified. By switching from finding the minimum priority to the maximum priority, the system will now correctly select the region intended to have precedence when multiple regions overlap, ensuring proper application of region-specific rules.
Highlights
- WorldGuard Region Priority Logic: The logic for determining the 'highest priority region' in WorldGuard has been corrected to correctly identify the region with the numerically highest priority value, rather than the lowest.

Code Review
This pull request correctly fixes a bug in highestPriorityRegion by changing from min() to max() to find the WorldGuard region with the highest priority. This is the correct approach as higher integer values represent higher priority in WorldGuard. I have added one suggestion to further improve the code by using Optional more idiomatically, which will enhance code safety and readability.
| @Nullable | ||
| private ProtectedRegion highestPriorityRegion(ApplicableRegionSet applicableRegions) { | ||
| return applicableRegions.getRegions().stream() | ||
| .min(Comparator.comparingInt(ProtectedRegion::getPriority)) | ||
| .max(Comparator.comparingInt(ProtectedRegion::getPriority)) | ||
| .orElse(null); | ||
| } |

This method can be improved by returning an Optional<ProtectedRegion> instead of using @Nullable. This change aligns with modern Java best practices for handling potentially absent values, making the code safer by leveraging the type system to enforce checks for presence and eliminating the risk of NullPointerException from an unchecked null return. It also enables callers, such as the getRegion method, to use a more fluent and declarative style with Optional chaining.
private Optional<ProtectedRegion> highestPriorityRegion(ApplicableRegionSet applicableRegions) {
return applicableRegions.getRegions().stream()
.max(Comparator.comparingInt(ProtectedRegion::getPriority));
}
Current priority finds the lowest priority instead of highest
