+/**
+ * OBoos
+ * 
+ * Args use path indices or path points. Recommended to use a span of 10
+ * for each IPathSpan as that's how the original game did it. Ex. IPathSpan(10, 20)
+ * 
+ * Once boos are active, they do not deactivate until the player drives into leftBoundary
+ * or rightBoundary. leftBoundary is really only used to deactivate the boos when the player is
+ * driving in the reverse direction.
+ * 
+ * @arg numBoos to show, default 5, maximum 10 allowed due to limited splines
+ * @arg leftBoundary When the player enters this area, deactivate the boos.
+ * @arg active When the player enters this area, activate the boos.
+ * @arg rightBoundary When the player enters this area, deactivate the boos.
