Overloads
| EvaluateProximity(Point[]) |
Returns a ranking for the polygon as the probable touch target and an adjusted touch point within the polygon. The rank is determined through a comparison of targeting heuristics for all polygons that intersect the touch contact area. |
| EvaluateProximity(Rect) |
Returns a ranking for the rectangle as the probable touch target and an adjusted touch point within the rectangle. The rank is determined through a comparison of targeting heuristics for all rectangles that intersect the touch contact area. |
EvaluateProximity(Point[])
Returns a ranking for the polygon as the probable touch target and an adjusted touch point within the polygon. The rank is determined through a comparison of targeting heuristics for all polygons that intersect the touch contact area.

- controlVertices
- Point[]
The array of x-y screen coordinates that define the shape of the UI element (the number of vertices in the polygon). This value must be greater than or equal to 3.
