Undead Sunscreen

Undead Sunscreen changes daylight burning behavior for mobs in Minecraft 1.21.1 on NeoForge.

By default, the mod protects every mob from vanilla daylight sunburn. Zombies, skeletons, and other mobs that would normally ignite in the sun will no longer start burning from daylight unless you explicitly blacklist them in the config.

Configurable Vanilla Behavior Blacklist

The config includes a sunburnBlacklist list. It is empty by default, which means the mod applies to all mobs.

Add an entity ID to the list when you want that mob to keep normal vanilla daylight burning behavior.

Example

sunburnBlacklist = ["minecraft:zombie", "minecraft:skeleton"]

With that config:

• minecraft:zombie uses vanilla daylight burning behavior.
• minecraft:skeleton uses vanilla daylight burning behavior.
• Any mob not listed is protected from daylight sunburn.

What It Changes

• Stops unlisted mobs from burning because of daylight.
• Keeps vanilla behavior for mobs listed in sunburnBlacklist.
• Supports vanilla and modded mobs through normal entity IDs.
• Does not change lava, fire, campfires, fire aspect, or other non-daylight fire damage.

Notes

• Use full entity IDs such as minecraft:zombie.
• The config is generated after the mod is run once.
• Existing worlds can use the mod without datapacks or commands.
