## Remarks

The [ColliderDistance2D](/engine/6000.7/script-reference/unityengine/colliderdistance2d.md) primarily defines a point on the exterior of each [Collider2D](/engine/6000.7/script-reference/unityengine/collider2d.md) along with the [\_distance](/engine/6000.7/script-reference/unityengine/colliderdistance2d/distance.md) between those two points.  The [\_distance](/engine/6000.7/script-reference/unityengine/colliderdistance2d/distance.md) between them can be positive indicating that the [Collider2D](/engine/6000.7/script-reference/unityengine/collider2d.md) are separated (not overlapped), zero indicating that they are touching (but not overlapped) or negative indicating that they are overlapped.

A [\_normal](/engine/6000.7/script-reference/unityengine/colliderdistance2d/normal.md) is provided that is a normalized vector that points from [\_pointB](/engine/6000.7/script-reference/unityengine/colliderdistance2d/pointb.md) to [\_pointA](/engine/6000.7/script-reference/unityengine/colliderdistance2d/pointa.md).  This vector, when scaled with the [\_distance](/engine/6000.7/script-reference/unityengine/colliderdistance2d/distance.md), provide a vector that can be used to move the [Collider2D](/engine/6000.7/script-reference/unityengine/collider2d.md) so that they are no longer overlapped (if the [\_distance](/engine/6000.7/script-reference/unityengine/colliderdistance2d/distance.md) is negative) or so they are touching (if the [\_distance](/engine/6000.7/script-reference/unityengine/colliderdistance2d/distance.md) is positive).

A common use-case for this is solving overlaps between two [Collider2D](/engine/6000.7/script-reference/unityengine/collider2d.md), particularly when attached to a [Rigidbody2D](/engine/6000.7/script-reference/unityengine/rigidbody2d.md) set to be [RigidbodyType2D.Kinematic](/engine/6000.7/script-reference/unityengine/rigidbodytype2d/kinematic.md).
