LineToolsLineIntersect(Vector2, Vector2, Vector2, Vector2, Boolean, Boolean, Vector2) Method

This method detects if two line segments (or lines) intersect, and, if so, the point of intersection. Use the firstIsSegment and secondIsSegment parameters to set whether the intersection point must be on the first and second line segments. Setting these both to true means you are doing a line-segment to line-segment intersection. Setting one of them to true means you are doing a line to line-segment intersection test, and so on. Note: If two line segments are coincident, then no intersection is detected (there are actually infinite intersection points). Author: Jeremy Bell

)

Parameters

point1  Vector2
The first point of the first line segment.
point2  Vector2
The second point of the first line segment.
point3  Vector2
The first point of the second line segment.
point4  Vector2
The second point of the second line segment.
firstIsSegment  Boolean
Set this to true to require that the intersection point be on the first line segment.
secondIsSegment  Boolean
Set this to true to require that the intersection point be on the second line segment.
point  Vector2
This is set to the intersection point if an intersection is detected.

Return Value

Boolean
True if an intersection is detected, false otherwise.
