Ammeter animation

[Keith Smith]

The gauge fluidity of the ammeter seems off compared to all the other engine gauges. Is it being drawn differently than all the others?

 

I was doing some electrical system testing, and as the generator amperage was slowly coming down (it was just about done charging the batteries), the ammeter wouldn't move at all, then it would suddenly drop down a few notches (in one repaint, not smoothly)...then freeze again. This repeated all the way until it settled down to around 80amps (the new base draw that I set up in PlaneMaker).  

 

How is the gauge being drawn and why isn't it as smooth as all the other gauges?

Because the animation is driven by plugin. At the end the value is correct but meanwhile if the real value is 80.. and it is in 0.. it won't jump from 0 to 80 instantly.. but will animate to 80. If any modification is made.. then it will move again reaching a closest value to 80 and then moving to the newer value.

Understood...but the amperage is dropping slowly, ie. 0.05 amps per second...then you would expect a slow, steady movement of the needle. This is not what happens. You can try it by letting the battery drain for a while (engine off, master on), then start engine, run the generator...and watch the generator output in settings->data input & output. As the battery charges, the generator load will slowly reduce...and you'll be able to observe what I'm referring to. If you'd like me to take a video of it, let me know.

 

I'm guessing it's a rounding error or truncation of some sort.

 

The needle doesn't move down slowly or steadily. Instead, every couple of seconds, it 'bumps' down a notch.

There is a range to compare between the actual value of animation and the final value. If it is too near then you will see that slowly animation... and when it is too close jumps a little. Yes.. that is normal.
