Why?

During your many playthroughs of Minecraft, you may have noticed the extreme nearsightedness of mobs in the game. As long as you stay more than 16 blocks away from a creeper, it will never come after you. Since mobs do not spawn within 24 blocks of the player, this means it is easy to survive: just stay still and there is only a minuscule chance a mob will wander close enough.

What?

By default, this mod increases the follow range of hostile mobs to 24 blocks. On hard mode, mobs get an additional 8 blocks added to their follow range. Additionally, a small modifier is added to the follow range based on the local difficulty. 

On the default settings, this makes it so mobs are far more likely to come after the player, especially at higher difficulties. 

How?

Modpack creators might desire more flexibility. How does this mod work and how can you use it to the fullest extent?

From 3.0.0 onwards, Farsighted Mobs uses a rule-based system: when a mob spawns in the world, each rule is evaluated and, if the rule applies to the mob, modifies the attributes of the mob. These rules are loaded from datapacks, and can thus be fully configured. The default set of rules checks conditions such as entity types and difficulty.

Additional rules are easy to add and the format is documented on the mod's wiki page. Examples of things the mod could do if you wanted it to: creepers spawned during rain are larger and have more health, mobs spawned before the nearest player achieved an advancement have less health, or drowned spawned in swamps can move faster.

Note that only newly-spawned mobs are affected. Mobs that were already in the world before you installed the mod or changed the config will not be affected.

This mod is fully server-sided and clients do not need to install it.

This version will no longer be maintained. See this page for the newer version.

During your many playthroughs of Minecraft, you may have noticed the extreme nearsightedness of mobs in the game. As long as you stay more than 16 blocks away from a creeper, it will never come to blow you up. Since mobs do not spawn within 24 blocks of the player, this means it is easy to survive: just stay still and there is only a minuscule chance a mob will wander close enough.

No more of that. By default, this mod increases the follow range of every hostile mob to at least 32 blocks, making the game a lot harder. This behaviour is fully configurable from the config. Not only can the minimum range of all hostile mobs be changed this way, you can even override individual mob types. Want all skeletons to be snipers that can spot you from a hundred blocks away? Do you prefer zombies to be so blind you have to literally bump into them? The power is yours!
 
This mod is entirely server-sided and is not required on the client side.

Note that only newly-spawned mobs are affected. Mobs that were already in the world before you installed the mod or changed the config will not be affected.
