translation, rotation and scale) will follow with high accuracy the animation curve you have set.

4. The relation between keyframe data and property values

A frequent source of mistake is that although we have set all the necessary keyframes for the

animation of a chosen object, when playing starts and the Page is initiated, for a split second the

Object is seen at one point then the animation itself starts from another point. This phenomenon

is due to the fact that the momentary value of the properties of the objects can be entirely

different to the value set in the keyframes for the same property. Keyframe animation does not

replace or invalidate the value of properties, it modifies them only during playback.

For instance: we set the animation of the TranslateX property of an object with a duration of 1

second, start value of -2 and end value of +2. If we switch Record mode off, and set the value of

TranslateX to zero, this will not influence the animation at all. Nevertheless, when we save the

data, with this value as the current value of the TranslateX property, the object will always be

shown according to this value until playback starts. When that happens, it jumps to -2 then

continues to change until it reaches +2.

It is worth remembering this, and it is a very good practice to always set the current value of

animated properties to the same value as the first keyframe. You can do this automatically if you

check the ResetObjects setting in the Settings menu. If this option is On, every time you rewind

the animation by clicking on the Stop button twice, all property values are set to the first keyframe

value if there is animation defined for them. This can help you a great deal if you have different

values saved as current values of properties than those saved as their keyframes.

5. Actions

As already mentioned several times, with Objects defined for a given Page you can create

different animations. It is possible to define separate animations for animating the Objects of a

Page On, and set another animation to animate the same Objects Off. Of course there can be

any number of animations that do something other than On or Off, we could call them Between

type animations. You should always remember though that the values of animated properties of

the Objects are not independent from one Action to the next.

An example: you have an Object in an action named Action1, which you move from point A to

point B by changing its TranslateX property. Then you move the same Object in Action 2 from

1 2 ... 75 76 77 78 79 80 81 82 83 84 85 ... 124 125
