; Simple picture window script that allows you to simulate the motion

; of a projectile at varying angles/speeds acting under conditions

; similar to those encountered in real life

;

; Copy the code into Remotes and type /cannon to start it.

; The rest should be quite self explanatory, you start it moving by

; pressing "project", pause it at any time with "pause", and reset it

; to the beginning with "reset"

;

; The scrollbars let you select an angle or initial speed of projection

; by either clicking on an area of the scroll bar, or dragging the pointer

;

; You can seek to specific instants of the projection by using the time

; scroll and also view information about the components of velocity and

; and displacement at any time
