| [canEncroach](/engine/6000.7/script-reference/unity/u2d/physics/physicsquery/castshapepairinput/canencroach.md)   | Allow cast shape proxies to encroach when initially touching. This only works if the radius is greater than zero. |
| [maxFraction](/engine/6000.7/script-reference/unity/u2d/physics/physicsquery/castshapepairinput/maxfraction.md)   | The maximum fraction of the translation to consider in the range (0 to 1), typically 1.                           |
| [shapeProxyA](/engine/6000.7/script-reference/unity/u2d/physics/physicsquery/castshapepairinput/shapeproxya.md)   | A proxy to the shape A.                                                                                           |
| [shapeProxyB](/engine/6000.7/script-reference/unity/u2d/physics/physicsquery/castshapepairinput/shapeproxyb.md)   | A proxy to the shape B.                                                                                           |
| [transformA](/engine/6000.7/script-reference/unity/u2d/physics/physicsquery/castshapepairinput/transforma.md)     | The world transform for shape A                                                                                   |
| [transformB](/engine/6000.7/script-reference/unity/u2d/physics/physicsquery/castshapepairinput/transformb.md)     | The world transform for shape B                                                                                   |
| [translationB](/engine/6000.7/script-reference/unity/u2d/physics/physicsquery/castshapepairinput/translationb.md) | Translation of the shape proxy B.                                                                                 |
