Rigid Animation

Rigid body animation is perhaps the simplest of methods for moving any thing around your stage, including Sketches, Shapes, Props, Vehicles and Characters.
To start, point at the thing you want to animate, press the Inspect button and select Start Motion from the Inspect Menu. (This step is not needed for character puppets as they are always animated.) This will create a keyframe on the Timeline.
You can now scrub the timeline and use the Grabber to move the thing to create a new keyframe. When you scrub between those keyframes, the thing will move: it will follow a smooth spline between the points and uses speed curves to start and stop smoothly.
The animation will have an associated Motion Path visible in the scene. If it hides away, point at the thing again to bring it back. You can use this to scrub time to where you want.
From the Timeline, you can move keyframes in time to change the speed of the animation. You can also spped up or slow down the whole animation by dragging an end handle.
You can change how the animation behaves between keyframes, by going to the Timeline, pointing at the animation and pressing the Inspect button: then choose the Edit option in the pop-up menu.
You can now see the properties for the animation:
Path Shape
Choose between: Jump - motion jumps directly between keyframes Straight - motion moves in straight lines between keyframes Curve - motion follows a smooth curve between keyframes
Speed Profile
Choose between: Uniform - motion is at a constant speed between keyframes Smooth Start And Stop - motion is mostly uniform but starts smoothly at the first keyframe and stops smoothly at the last. Pause At Each Key - motion starts and stops at each keyframe, coming to a brief pause there.
There is also an action, Set Constant Speed, which changes the timing of the keyframes so the thing travels equal distance in equal time.
