Animated MetaAttributes

Animated metaattributes depend on the current frame within SynthEyes, for example a camera's position or a tracker's location.

You can also talk about the value on a particular frame, for example

tracker 1's location on frame 10.

Likewise you can change the value on a different frame:

make tracker 2's weight 0.6 on frame 15.

This statement changes the current frame, based on the value on a specific frame:

make tracker 2's weight its weight on frame 30.

Exercise: how do you set the value on one frame from a value on another?
