Environment2DWithObstacles

interface Environment2DWithObstacles<W : Obstacle2D!, T : Any!, P : Position<out P>!> : Environment<T, P>

addObstacle	Adds an `Obstacle2D` to this environment. `abstract fun addObstacle(o: W): Unit`
getObstacles	`abstract fun getObstacles(): MutableList<W>!`
getObstaclesInRange	Given a point and a range, retrieves all the obstacles within. `abstract fun getObstaclesInRange(centerx: Double, centery: Double, range: Double): MutableList<W>!`
hasMobileObstacles	`abstract fun hasMobileObstacles(): Boolean`
intersectsObstacle	Checks whether there is at least an obstacle intersecting the line connecting [sx, sy] and [ex, ey]. `abstract fun intersectsObstacle(sx: Double, sy: Double, ex: Double, ey: Double): Boolean` Checks whether there is at least an obstacle intersecting the line connecting p1 and p2. `abstract fun intersectsObstacle(p1: P, p2: P): Boolean`
next	This method must calculate the RELATIVE next allowed position given the current position and the position in which the node wants to move. For example, if your node is in position [2,3], wants to move to [3,4] but the next allowed position (because, e.g., of physical obstacles) is [2.5,3.5], the result must be a `Position` containing coordinates [0.5,0.5], so it's the relative movement considering the starting position as origin. `abstract fun next(ox: Double, oy: Double, nx: Double, ny: Double): P`
removeObstacle	Removes an `Obstacle2D` from this environment. `abstract fun removeObstacle(o: W): Boolean`
