For a bone movement of mine. I'm able to move all the joints except for the main pivot, which in my case is the torso. I'm wondering if this is a design decision or a bug?
It makes it really hard to do a "ducking" animation, since you can't actually move your character 'down' to the ground, he simply goes into the ducking animation but hovers above the ground
I ran into a similar problem when I was playing around with bones. The only way I can suggest to fix it is to make an event that increses the Y coordinate of the player when the ducking animation is being played.
You will need one variable for the characters "original Y" and then through trial and error, work out how many pixels down the character has to move when ducking, and how many pixels to move it by per tick in order to make it look right. Once you figure that out, make a second varible "ducked Y" or something like that, and you should be able to work the rest out from there.
