YSortContainer

Sorts children by Y position each frame for top-down perspective.

API

class simvx.core.nodes_2d.ysort.YSortContainer(**kwargs)[source]

Bases: simvx.core.nodes_2d.node2d.Node2D

Sorts children by Y position each frame for top-down perspective.

Children are drawn in Y-ascending order (lower Y = drawn first = behind), which creates a natural depth effect for top-down 2D games. The sort only affects draw order; the children list itself is not mutated.

Uses dirty-flag optimization: O(n) comparison instead of O(n log n) sort when no child Y values have changed.
