Portal Tier Tagger

Fabric mod for Minecraft 1.21.1 that displays Portal Tiers rankings above nearby players' nametags, with custom font/emoji icons per gamemode.

Building

This project uses Fabric Loom. A Gradle wrapper properties file is included, but the wrapper jar/scripts are not (binary files aren't included here) — either:

• Run gradle wrapper once with a local Gradle 8.8 install to generate gradlew / gradlew.bat / gradle/wrapper/gradle-wrapper.jar, then use ./gradlew build from then on, or
• Open the project directly in IntelliJ IDEA with the Fabric/Loom setup and let it sync, or
• Use your own Gradle installation: gradle build.

Build output (the mod jar) will be in build/libs/.

Recent fix: nametag rendering

The nametag tier renderer was registered on WorldRenderEvents.LAST, which fires after the shared entity vertex buffer for the frame has already been flushed to the GPU — so the tier text was queued into a buffer that never got drawn. It now registers on WorldRenderEvents.AFTER_ENTITIES, which runs before that flush. See the comment in PortalTierTagger.onInitializeClient() for details.
