Sorry to interfere, just passing by, but probably I can explain:
I suppose
@Astromen has meant the same thing as
@kadakash1, literally "if the birth animation was stand hit instead".
1. As it was already highlighted by
@kadakash1 in Warcraft 3 "stand hit" is a typical animation for desctructible being attacked - and usually it is cycled, like the one for a tree - but the "stand hit" here is not.
2. More than that, these chests' "stand hit" animations are literally "birth" animation of a standard chest (you can check it, if you have Warcraft 3).
3. These chests' "birth" animations behave just like typical "stand hit" animation for Warcraft 3 destructibles - they are cycled and dispays chests being hit.
Some 'difffilculty' here comes from the fact, that the standard Warcraft 3 chest is open, while playing its "stand" animation, whereas chests here are closed 'by default'
But this is not an unsolvable problem.
I commented this mostly for making more love and not misunderstanding. And practicing in writing sentences in English, probably
