For example, say i wanted to recreate a speedometer.
Has anyone tried making a gauge on a touch panel. For example, say i wanted to recreate a speedometer. Can i make a bargraph that fills over a radius?
TPDesign4 actually has its own set of Tween functions, although I don't use them, and I don't know anyone who does.
There's an example of images that Dave H posted which you can find by doing a forum search for "compass" (well I believe that should find it).
You basically create an animatioin that uses level values to determine which of animated frames to display. You could achieve the same results with the ^ani command but most folks use would use a multi-state bar graph.
I did a touch panel that had a sort of Jules Verne - 20 000 leagues under the sea look to it. It had a polished brass with a faded paper look to the dail backgrounds. The pointers had a fleur-de-lac end. It was pretty over the top. I suppose it could be tamed down and moderinzed for your uses. I had a compass, wind-speed gauge in MPH, humidity, barometric pressure and a glass and mercury thermometer.
The clock was silly.
I'll see if I can dig it up if you're interested.
You can generally get by with a lot less frames with almost no visual difference as the eyes are easily decieved!
I use them. They are convenient if you want a button to fade over time from one state to another, or one color to another. I haven't used them for animations, nor do I think that was the intent. But it's kind of neat to make a 10-state button that instead of instantly going from it's "dim" off state to a birght on state, will gradually brighten or change color. I will typically use that type of button to show whether a particular source is active, or a system mode set. You can even "tween" font sizes, which is also a cool effect.
