‌Changing a MetaAttribute's Value

To make a metaobject's metaattribute a metavalue , ie change its value, you say exactly that: make tracker 103's weight 0.5 or make the solver mode of camera 1 tripod.

When a metaattribute's values are named metavalues, it is frequently unnecessary to cite a specific metaattribute; you can make a metaobject a metavalue, eg make camera 1 zoom . Here, zoom is a lensmode, and a lensmode is the value only of a camera's lens mode metaattribute. So make camera 1's lens mode zoom is unnecessarily wordy.

The actual make rules are

make some metaobjects's a metaattribute a metavalue

make the a metaattribute of some metaobjects a metavalue make some metaobjects a metavalue

Accordingly, a single make sentence can change many metaobjects simultaneously.

A metavalue can encompass several simple metavalues, so you can change several named metaattributes at once.

Exercise: make all trackers unlocked and far—but a little quicker.

Note that to eliminate ambiguity, some metaattributes of a metaobject may be hidden. For example, trackers have primary, alternate, and net color metaattributes in addition to the nominal color metaattribute; all the others are hidden.

Exercise: find all the hidden metaattributes, and how to hide one.
