I have an idea for simulating instruments on the Amiga (to use in teaching in this instance, but the applications could be broader) and am wondering which is the best way to develop it. I suspect CanDo will be the best choice, but I haven't used this program so I would appreciate any advice. I've borrowed the manual and program with a view to purchasing it if I can get this idea to work, and am beginning to wade into it, but it's all still a little unclear. What do I want to do? Well, I'd like a picture of the front panel of an instrument with "active" knobs, buttons, sliders, etc. When the student fiddles with these he or she should see the appropriate effect elsewhere on the screen. Let's take a chart recorder as an example. One should be able to "turn" the zero knob and see the pen move up and down the chart. I can think of two ways to do this. One would be to divide the knob into two logical halves; clicking on the right half would cause the knob (an animbrush?) to start rotating clockwise as long as the mouse button was held down — the left half of the "knob button" (hmmm this terminology could get confusing!) should do the opposite. Another way would be to drag inside the "knob button," with the direction and extent of knob rotation depending on the drag direction and amount. In either case, the knob rotation should be coupled to the movement of a pen brush. Is any of this possible? Is CanDo the best program for the job? I'd appreciate any comments or suggestions. If someone has done this sort of thing already and could show me an example of how it works, that would be wonderful — I haven't found anything like this in the example decks over in AmigaVendor, but may have overlooked something.
