I've been having trouble using a motion tween in an animation I'm creating. I have an object (a cartoon character's talking head) that I'm trying to move along a motion tween. At one point I want to make him stop moving for a beat, then continue. However, when I have two keyframes in the same place, the object will move up and down between the two keyframes that have the same position and rotation. When I click on the tween's path, I don't see anything that would make the object move (at least I don't think so, it's a small movement),
I looked around and couldn't find any fixes on the interwebs. However, it does seem similar to the "boomerang effect" of motion paths in AE. Especially since it appears to only happen when I make the motion paths into a curve.
I'm using Flash CS4.
Any help would be greatly appreciated!!
I'm not sure exactly what you mean, however I've noticed that the problem also occurs with different single layer objects. So I don't believe it's the complexity of the object itself.
Specifcally, it seems to only happen when I had a curve to the motion tween path.
Why? What's the difference between having multiple keyframes that are at the same point on a tween, and multiple keyframes at different points? This makes the motion tween more burdensome than the classic tween, especially since I have at least 18 different rest points.
In AE, you can put a stop on a keyframe to prevent this effect. Seems like an obvious oversight if there's no fix in flash...
i'm not arguing with you. i'm just telling you how to prevent tweening between two frames.
if you want to do it your way, do it your way. but, while it may seem obvious to you that there should be no tweening between two keyfames with identical content, it's not obvious to flash especially when you add a motion tween between those two identical keyframes.
that said, you should double check the two keyframes and make sure the object's properties are indentical (using the properties panel).
