Be specific in what you want your object to do, and you??™ll have
an easier time creating motions.
Now, there are a few things to know about TCB and how to set the values:
?—? T, C, and B values can range from -1.0 to 1.0.
?—? Tension is used to ease in or ease out of a keyframe. You would set a tension of 1.0
to make an item slow down as it reaches its keyframed position. On the flipside,
you??™d use a tension of -1.0 to make an object speed up as it reaches its specified
position??”perhaps for things like a ball bouncing. As we??™ve seen, to set tension
using the Move TCB tool, just click and drag in an item??™s desired keyframe.
?—? Continuity is used to smooth or punctuate changes in motion. A positive continuity
setting tells an object to ???glide??? smoothly as it passes through a keyframe.
A negative continuity setting briefly ???freezes??? an item in its keyframed position
before its motion continues, and is useful for exaggerated or robotic character
movements. To set continuity using the Move TCB tool, hold the Ctrl key and
click and drag in an item??™s desired keyframe.
?—? Bias is used for setting up anticipation.
