Animating a shape
Now you will try animating a shape.
1. Advance to frame 11 in the Timebar and with the Select All tool click a point to
move your Bézier around a little and change the shape.
2. Move the Timebar from the first keyframe to the second keyframe and see the
shape animating from one to the other.
Keyframes are added automatically in RotoPaint due to the Autokey check box
being checked in the Tool Settings bar ( FIGURE 6.16 ).
Figure 6.16. Changing the shape will result in a keyframe for which the Au-
tokey check box is checked.
The Autokey check box is checked by default, meaning the moment you start
drawing a shape, a keyframe for that shape is created and gets updated on that
frame as you are creating the shape. Moving to another frame and changing the
shape creates another keyframe and thus creates animation. If, before you start
drawing, you uncheck the Autokey check box, drawing will not create a key-
frame. Ifyouthen move toanother frame andchange the shape, nokeyframe will
be created either, and neither will animation. Having a keyframe and then un-
checking the Autokey check box, and then changing the shape will only do those
things temporarily—if you move to the next frame, the shape will immediately
snap to the last available keyframe. You have to turn on the Autokey check box if
you want to keep the new shape after changing it.
