I have been playing around with the inverse kinematics in flash. I have built a character that moves and animates very well. My question is in regards to swaping symbols. I would like to swap out different head symbols that have different facial expressions. When I do this though the symbol I swap changes for every frame I have made in the animation. How can I swap symbols for individual frames? I would like to make my character talk. If this is not possible how would I animate the mouth of IK character? Any tutorials out there that cover this issue?
