Mediumcore Fix

Fixes health data loss when updating Alex's Mediumcore mod

Problem

The original Mediumcore in onLivingDeath uses player.getMaxHealth(), which INCLUDES modifiers from external sources (rings, armor, etc.).

Example with a +20 HP ring:

maxHealth = 40 (20 base + 20 ring)
clippedHealth = clip(40 - 2, 6, 20) = 20 (clamped to maxPlayerHealth!)
healthModifiedBy = 0 + (20 - 40) = -20!
After respawn: maxHealth = 20 + 0 + (-20) = 0 HP → the player gains 1 HP.

Solution

Introduce BASE_HEALTH_TAG to store the "pure" base health, which is independent of external modifiers.

Frequently Asked Questions

Mediumcore Fix server crashes on startup – what to do?

Most common cause: wrong forge version or insufficient RAM. Check the server log (latest.log) for "OutOfMemoryError" or "Mixin" errors. With Mado Hosting: ensure at least 3 GB RAM is allocated and the loader matches the mod version (1.20.1). You can switch loaders with one click in the panel.

Is Mediumcore Fix compatible with forge?

Mediumcore Fix officially supports forge for Minecraft 1.20.1. The Mado dashboard automatically detects incompatible loader combinations.

Server lagging with Mediumcore Fix – how to optimize performance?

Recommended RAM: 4 GB (per 8 players). Use /spark profiler to check if Mediumcore Fix consumes the most tick time. Common fixes: reduce server view-distance to 8-10, install "performant" or "starlight" as supplementary mods on Forge. With Mado Hosting, your server runs on NVMe SSDs with dedicated CPU cores for minimal latency.
