Distance Functions

deceleration_distance(speed,friction)   Returns the distance travelled by an object moving at the given speed with the given rate of deceleration. instance_closest_approach(inst)   Returns the closest distance that a given instance will approach the current instance. instance_nth_farthest(x,y,obj,n)   Returns the id of the nth farthest instance of type obj from (x,y). instance_nth_nearest(x,y,obj,n)   Returns the id of the nth nearest instance of type obj to (x,y). point_line_distance(x1,y1,x2,y2,x3,y3,segment)   Returns the distance from a given point to a given line. range_finder(x,y,dir,range,object,prec,notme)   Returns the exact distance to the nearest instance of the given object in the given direction from the given point.
