Package Contents¶

mini_arcade_core.spaces.collision.intersects(collider_a: mini_arcade_core.spaces.collision.specs.ColliderSpec | None, transform_a: mini_arcade_core.spaces.geometry.transform.Transform2D, collider_b: mini_arcade_core.spaces.collision.specs.ColliderSpec | None, transform_b: mini_arcade_core.spaces.geometry.transform.Transform2D, *, inclusive: bool = True) → bool¶

Generic intersection entrypoint.

Currently implemented: - rect vs rect

Behavior: - None collider is treated as rect using transform size.

mini_arcade_core.spaces.collision.intersects_entities(a: mini_arcade_core.engine.entities.BaseEntity, b: mini_arcade_core.engine.entities.BaseEntity, *, inclusive: bool = True) → bool¶: Convenience entity-level intersection.

mini_arcade_core.spaces.collision.rect_rect(*, ax: float, ay: float, aw: float, ah: float, bx: float, by: float, bw: float, bh: float, inclusive: bool = True) → bool¶: Axis-aligned rectangle intersection.
