s_missile(..., trg, homing = 1, speed = 1)
- Fires a projectile of the specified sort at the [trg]; if [homing] is equal to 1, it will adjust its flight path to follow [trg], should [trg] change locations. Otherwise, it will not. Between steps, it will wait [speed] x 1/10 seconds. (A speed of zero would mean that the projectile would not be seen, and it would fly directly to its target and delete itself instantaneously; you can probably conceive of a use for that behaviour!)
walk_line(ref,trg,lag) - Moves [ref] on a straight path towards [trg], not taking obstacles into account, preceding each successive step with [lag] seconds of inactivity.
Though the library includes other functions, those functions are designed to provide the internal calculations necessary for the library, and it is doubtful that they will be of any use to the user.
