| [ContactFilter2D](/engine/6000.0/script-reference/unityengine/contactfilter2d.md) | A copy of the contact filter set to not filter any [ContactPoint2D](/engine/6000.0/script-reference/unityengine/contactpoint2d.md). |

### Remarks

When you are using a function that requires a [ContactFilter2D](/engine/6000.0/script-reference/unityengine/contactfilter2d.md), but you don't want to perform any filtering, then use this function to return a [ContactFilter2D](/engine/6000.0/script-reference/unityengine/contactfilter2d.md) that turns off any filtering.

Call this function to set the contact filter to [ContactFilter2D.layerMask](/engine/6000.0/script-reference/unityengine/contactfilter2d/layermask.md) = [Physics2D.AllLayers](/engine/6000.0/script-reference/unityengine/physics2d/alllayers.md), [ContactFilter2D.minDepth](/engine/6000.0/script-reference/unityengine/contactfilter2d/mindepth.md) = [Mathf.Infinity](/engine/6000.0/script-reference/unityengine/mathf/infinity.md), [ContactFilter2D.maxDepth](/engine/6000.0/script-reference/unityengine/contactfilter2d/maxdepth.md) = [Mathf.Infinity](/engine/6000.0/script-reference/unityengine/mathf/infinity.md), [ContactFilter2D.minNormalAngle](/engine/6000.0/script-reference/unityengine/contactfilter2d/minnormalangle.md) = [Mathf.Infinity](/engine/6000.0/script-reference/unityengine/mathf/infinity.md) and [ContactFilter2D.maxNormalAngle](/engine/6000.0/script-reference/unityengine/contactfilter2d/maxnormalangle.md) = [Mathf.Infinity](/engine/6000.0/script-reference/unityengine/mathf/infinity.md).
