Remarks
Compute distance to the floor from bottom sphere of capsule and store the result in OutFloorResult. This distance is the swept distance of the capsule to the first point impacted by the lower hemisphere, or distance from the bottom of the capsule in the case of a line trace. This function does not care if collision is disabled on the capsule (unlike FindFloor).
Parameters
| Name | Description |
|---|---|
| CapsuleLocation | Location of the capsule used for the query |
| LineDistance | If non-zero, max distance to test for a simple line check from the capsule base. Used only if the sweep test fails to find a walkable floor, and only returns a valid result if the impact normal is a walkable normal. |
| SweepDistance | If non-zero, max distance to use when sweeping a capsule downwards for the test. MUST be greater than or equal to the line distance. |
| OutFloorResult | Result of the floor check. The HitResult will contain the valid sweep or line test upon success, or the result of the sweep upon failure. |
| SweepRadius | The radius to use for sweep tests. Should be <= capsule radius. |
| DownwardSweepResult | If non-null and it contains valid blocking hit info, this will be used as the result of a downward sweep test instead of doing it as part of the update. |
