Classes

Path2D

Holds a Curve2D for path-following, positioned in 2D space.

PathFollow2D

Moves along a parent Path2D’s curve based on progress.

class simvx.core.nodes_2d.path.PathFollow2D(**kwargs)[source]

Bases: simvx.core.nodes_2d.node2d.Node2D

Moves along a parent Path2D’s curve based on progress.

Must be a child of a Path2D node. Updates position (and optionally rotation) each frame based on the current progress along the curve.
