mob

The Mob – anything that can appear on screen.

A Mob is an Animatable with a place in 3-D space: a location, a basis (its orientation and scale as three vectors), a color, an opacity and a glow. Assigning to any of them records an animation.

The class is assembled from mixins, each in its own mob_*.py module: movement and rotation, screen-relative layout, the parent/child hierarchy, morphing between shapes (become), and the shader and material API. This module holds the core – construction, Scene registration, batching, and the attribute definitions the mixins operate on.

Two rules are worth stating up front. Changes to a parent propagate to its children. And the material API (set_shader, set_fragment_shader, set_material) must be called before the Mob is spawned.

A Mob is not renderable by itself: a concrete subclass defines get_render_primitives(), returning flat triangles, curved PN triangles, or cubic bezier circuits.
