Methods

Combine(ref AABB)

Combine an AABB into this one.

public void Combine(ref AABB aabb)

Parameters

aabb AABB

The aabb.

Combine(ref AABB, ref AABB)

Combine two AABBs into this one.

public void Combine(ref AABB aabb1, ref AABB aabb2)

Parameters

aabb1 AABB

The aabb1.

aabb2 AABB

The aabb2.

Contains(ref AABB)

Does this aabb contain the provided AABB.

public bool Contains(ref AABB aabb)

Parameters

aabb AABB

The aabb.

Returns

bool

true if it contains the specified aabb; otherwise, false.

Contains(ref Vector2)

Determines whether the AAABB contains the specified point.
