APPLY_CREATURE_VARIATION versus APPLY_CURRENT_CREATURE_VARIATION

Based on testing, APPLY_CREATURE_VARIATION has instant effect (in reverse order, as noted elsewhere), whereas APPLY_CURRENT_CREATURE_VARIATION is used to manually apply any creature variation tags, such as CV_ADD_TAG or CV_REMOVE_TAG, that have been manually added to the creature definition instead of being defined in a creature variation. In other words, APPLY_CURRENT_CREATURE_VARIATION has no effect if you are simply using APPLY_CREATURE_VARIATION to load creature variations. Think of a creature variation defined in an OBJECT:CREATURE_VARIATION file as a "template", which is applied with APPLY_CREATURE_VARIATION. Think of a "current creature variation" as any manually-defined creature variations that have been added to the creature definition itself, which must be applied to the creature with APPLY_CURRENT_CREATURE_VARIATION after you have made all of the necessary modifications.

For example, the following is a use of APPLY_CREATURE_VARIATION, which takes instantaneous effect without any need for APPLY_CURRENT_CREATURE_VARIATION.:

	[APPLY_CREATURE_VARIATION:REMOVE_STUB_ARMS]

This is an example of the use of APPLY_CURRENT_CREATURE_VARIATION: [COPY_TAGS_FROM:MY_CREATURE]

	[CV_REMOVE_TAG:TISSUE_LAYER_UNDER]
	[TISSUE_LAYER_UNDER:BY_CATEGORY:BODY:GAS]
	[TISSUE_LAYER_UNDER:BY_CATEGORY:WING:GAS]
	[APPLY_CURRENT_CREATURE_VARIATION]
