mini_arcade_core.spaces.d2.boundaries2d¶

Boundary behaviors for 2D rectangular objects.

This module is transitional: - Supports the legacy d2 model (position, size, velocity) - Supports the new model (transform, kinematic)

Classes¶

`LegacyRectKinematic`	Legacy contract for something that can bounce.
`RectKinematic`	New contract for something that can bounce.
`VerticalBounce`	Bounce an object off the top/bottom bounds by inverting vertical velocity
`LegacyRectSprite`	Legacy contract for something that can wrap.
`RectSprite`	New contract for something that can wrap.
`VerticalWrap`	Wrap an object top <-> bottom.

Module Contents¶

class mini_arcade_core.spaces.d2.boundaries2d.LegacyRectKinematic¶

Bases: Protocol

Legacy contract for something that can bounce.

position: mini_arcade_core.spaces.geometry.bounds.Position2D¶
