### Remarks

Both centers must be finite and further apart than [\_minEdgeLength](/engine/6000.7/script-reference/unity/u2d/physics/physicsworld/minedgelength.md), and the radius must be finite and zero or greater. See [\_areEdgesValid](/engine/6000.7/script-reference/unity/u2d/physics/capsulegeometry/areedgesvalid.md) for the center separation on its own.
