Method FindIntersection
FindIntersection(in Vector2, in Vector2, in Vector2, in Vector2, out Vector2)
Calculates the intersection point defined by line_1 [p1, p2], and line_2 [q1, q2].
Declaration
public static int FindIntersection(in Vector2 p1, in Vector2 p2, in Vector2 q1, in Vector2 q2, out Vector2 intersection)Parameters
| Type | Name | Description |
|---|---|---|
| Vector2 | p1 | line_1 is defined by (p1, p2) |
| Vector2 | p2 | line_1 is defined by (p1, p2) |
| Vector2 | q1 | line_2 is defined by (q1, q2) |
| Vector2 | q2 | line_2 is defined by (q1, q2) |
| Vector2 | intersection | If lines intersect at a single point, then this will hold the intersection point. Otherwise, it will be Vector2.positiveInfinity. |
Returns
| Type | Description |
|---|---|
| int | 0 = no intersection, 1 = lines intersect, 2 = segments intersect, 3 = lines are collinear, segments do not touch, 4 = lines are collinear, segments touch (at one or at multiple points) |
