Attribute Meta Variables:

There are two types per listed attribute: a modifiable type referring to the base attribute value before modifiers are applied and following the format meta_attribute_<attributeName>_base; and an unmodifiable type following the format meta_attribute_<attributeName>, which only returns the value of the attribute after all modifiers are applied. In either case <attributeName> should be the lowercase attribute name, with . separators replaced with _ (e.g. generic.armor_toughness -> generic_armor_toughness -> meta_attribute_generic_armor_toughness(_base)). Find attribute names and their min and max values here.

Since 4.0 Beta 14:

All linked attributes existing in your server version have a meta attribute variable associated with them.

Before 4.0 Beta 14:

Only the following attributes meta-variable exist:

• meta_attribute_generic_max_health(_base)
• meta_attribute_generic_follow_range(_base)
• meta_attribute_generic_knockback_resistance(_base)
• meta_attribute_generic_movement_speed(_base)
• meta_attribute_generic_flying_speed(_base)
• meta_attribute_generic_attack_damage(_base)
• meta_attribute_generic_attack_knockback(_base)
• meta_attribute_generic_attack_speed(_base)
• meta_attribute_generic_armor(_base)
• meta_attribute_generic_armor_toughness(_base)
• meta_attribute_generic_luck(_base)
