The "time" is a value between 0.0 and 1.0 and can be used to calculate where the collision occured. Function Synopsis t, xn, yn = Shape:testSegment( x1, y1, x2, y2 ) Arguments number x1 The x

Source:getDuration Available since LÖVE 0.10.0 This function is not supported in earlier versions. Gets the duration of the Source. For streaming Sources it may not always be sample-accurate, and may return -1 if the duration cannot be determined at all.
