Shape:testSegment

Shape:testSegment

Removed in LÖVE 0.8.0
This function is not supported in that and later versions.

Checks whether a line segment intersects a shape. This function will either return the "time" of impact and the surface normal at the point of collision, or nil if the line does not intersect the shape. The "time" is a value between 0.0 and 1.0 and can be used to calculate where the collision occured.
