A result from a trace
The distance from the start of the trace to the Location in world space. This value is 0 if there was an initial overlap (trace started inside another colliding object).
Position of the actual contact of the trace shape (box, sphere, line) with the impacted object. Example: for a sphere trace test, this is the point where the surface of the sphere touches the other object.
Normal of the hit in world space, for the object that was hit by the sweep, if any. For example if a box hits a flat plane, this is a normalized vector pointing out from the plane.
The object that was hit
The position where the moving shape would end up against the impacted object. Equal to the point of impact for line tests. Example: for a sphere trace test, this is the point where the center of the sphere would be located when it touched the other object.
