Animation Tips
If you are thinking about creating complex layers of animation where some objects disappear and are replaced by
other objects on the same slide, step back and consider whether it would be easier to simply use two or more sepa-
rate slides. When there is no delay or animation dei ned in the transition between two slides (if their content is iden-
tical or very similar), the effect is virtually identical to that of layered, animated objects — with much less time and
effort required to set them up.
You can use layering when you want part of a slide to change while the rest of it remains
static. For example, you could create your own animated series of illustrations by stacking
several photos and then animating them so that the bottom one appears, then the next
one on top of it, and so on. This can provide a rough simulation of motion video from stills,
much like fl ipping through illustrations in the corners of a stack of pages. You can set the
animation speeds and delays between clips as needed to achieve the effect you want.
When you stack objects, the new object that is placed on top of the old object obscures
it, so it is not necessary to include an exit action for the old object. However, if the item
being placed on top is smaller than the one beneath, then you need to set up an exit effect
for the object beneath and have it occur concurrently (that is, With Previous) with the
entrance of the new one. For example, suppose that you want to place a photo on the right
side of a slide and some explanatory text for it on the left, and then you want to replace
these elements with a different photo and different text, as shown in Figure 16.25. At the
back of this topic in Lab 2, “Adding Sound and Movement to a Presentation,” you’ll learn
step-by-step how to set up this type of animation sequence.
FIGURE 16.25
Although these i gures look like two separate slides, they are actually a single slide at two
different points in the animation sequence.
To set up this animation to occur on the same slide, you would place the content that
should appear fi rst and then apply exit effects to it. For example, set the initial photo to
