An Anchor
is a point where a two-dimensional object, such as a Pic, attaches to other such objects; you can also think of it as a “pin” that attaches a Pic
to a background.
An Anchor
is a point where a two-dimensional object, such as a Pic, attaches to other such objects; you can also think of it as a “pin” that attaches a Pic
to a background.
For instance, a Pic
may have its Anchor
at its center; the Pic
may then be attached to a larger image at that image’s TopLeft
(another anchor), so that the center of the first Pic
is located at the top left-hand corner of the second Pic
.
The companion object of this class provides several standard Anchor
s and a class Anchor.Absolute
for creating new ones.
Anchor
objects are immutable.
This trait has an alias in the top-level package o1, so it’s accessible to students simply via import o1.*

This companion object of class Anchor
contains a number of standard anchors (TopLeft

trait ContainedObjecttrait MovingObjectInContainer
A supertype for objects that take up a rectangular area and have an anchoring point. The object’s pos
indicates the position of the anchoring point; the locations of its edges are determined relative to the anchor.

This subpackage defines a few additional traits that extend the ones in of o1.world.objects. These traits provide additional convenience methods for working with mutable objects in two-dimensional space.

NOTE TO STUDENTS: In this course, you don’t need to understand how this package works or can be used. That being said, some students may wish to experiment with some of its contents. Several of the traits in this package have aliases in the top-level package o1, so they are accessible to students simply via import o1.*
