Linear Motion

The animator functions used so far in the tutorial have all produced linear motion because they are linear functions of the form Ax + B, created by shifting & scaling. It is the simplest type of function and the most frequently used.

Other than moving an object in a straight line, linear animator functions are good for fading in and out using blendlevel, turning volume up and down smoothly, morphing color values, etc. Linear animator functions move a property or variable from a start value to an end value at a constant rate (the constant rate can be tweaked by biasing).

For examples of linear animator functions see any of these demos:
