Apologies if the use case was unclear; First person view game, you are climbing a ladder, so you have an animation of your hands climbing upward. Now you stop climbing, midway on the ladder. I expect that I can make my hand animation pause where it was (otherwise my hands would keep moving). Then I decide to continue climbing, so I would like the animation to continue from where it was.
Hope that is more clear.
EDIT: Just in case you did understand me, but are just seeking further clarification;
I don't think it would necessarily matter, but I'm not sure of the implication. When I'm finished climbing I would just transition back to either hands-idle, or if you had a weapon out it would be like hands-holster, then weapon-unholster, and then weapon-idle.
I probably could achieve this whole thing with a bit of guesswork but it wouldn't be an exact science. I would need to track the milliseconds passed since animation started so that I could calculate which frame I should be up to.
