❌ No More NPE

LivingDeathEvent.getSource() is null

Tired of random crashes caused by broken mods passing null DamageSource into entity death or damage events?

This mod adds a defensive guard to Minecraft’s damage & death pipeline, preventing servers and single-player worlds from crashing due to invalid DamageSource usage by other mods.

Instead of crashing your game, it will:

• ✅ Block the invalid call safely
• ⚠️ Log a warning or error with stack trace
• 🔍 Help you identify which mod caused the problem

So you can keep playing, and fix the real issue later.

🛡 What This Mod Does

This mod injects safety checks into:

• LivingEntity#hurt
• LivingEntity#die

If a mod incorrectly triggers damage or death with a null DamageSource (which should never happen), this mod will:

• Prevent the NullPointerException
• Allow the entity to continue behaving normally
• Print detailed logs to help modpack authors locate the culprit

---

🚨 Why This Exists

While vanilla and NeoForge expect DamageSource to never be null,
some mods still trigger events incorrectly and crash the entire game.

Normally, this results in errors like:

LivingDeathEvent.getSource() is null

Which kills servers and corrupts worlds for reasons outside the player's control.

This mod acts as a runtime safety net for such situations.

⚠ Important Notes

• ❗ This mod does not fix the broken mod — it only prevents crashes.
• ⚠ If you see warnings in logs, you should still report them to the mod author.
• ✅ Safe to use on both client and dedicated servers.
• 🧩 Designed to be lightweight and compatible with large modpacks.

📦 Modpack Friendly

If you're a modpack author or server owner, this mod can help:

• Prevent unexpected downtime
• Avoid corrupted worlds
• Collect useful crash info without stopping gameplay

Think of it as a circuit breaker for bad damage events.
