Zombies Follow Range...

Ok, so I did this:

Code:java

 
private static final UUID followRangeUID = UUID.fromString("1737400d-3c18-41ba-8314-49a158481e1e");
 
@EventHandler(priority = EventPriority.MONITOR, ignoreCancelled = true)
public void onEntitySpawn(CreatureSpawnEvent event){
LivingEntity entity = event.getEntity();
 
if (entity.getType() == EntityType.ZOMBIE){
EntityInsentient nmsEntity = (EntityInsentient) ((CraftLivingEntity) entity).getHandle();
AttributeInstance attributes = nmsEntity.getAttributeInstance(GenericAttributes.d);
 
AttributeModifier modifier = new AttributeModifier(followRangeUID, "Standoff Navigation Range multiplier", 0.2d, 1);
 
attributes.b(modifier);
}
}
 

But when I spawn a zombie they still have the same view range.

 

I'm confused. Are you trying to change a mob's navigation range or movement speed?

 

Navigation range.

 

This is how I set navigation range. It's completely different than yours.

Code:java

 
try {
Field field = Navigation.class.getDeclaredField("e");
field.setAccessible(true);
AttributeInstance e = (AttributeInstance) field.get(nmsEntity.getNavigation());
e.setValue(32); // Navigation distance in block lengths goes here
} catch (Exception ex) {
}
