Very nice! JSBsim isn's as bad as some people in the community want us to believe. After all, the Majestic Dash 8 Q 400 uses it as well. 

 

Is there a tutorial on implementing working gauges?

From User M7, who does wing-man videos that often end in tragedy. (Boom) 

 

Very nice! JSBsim isn's as bad as some people in the community want us to believe. After all, the Majestic Dash 8 Q 400 uses it as well. 

 

Is there a tutorial on implementing working gauges?

I don't think there's a tutorial for this, but I'll try to briefly explain it.

 

Implementing working gauges isn't that hard. Those are just objects that moves or rotates depending on a variable defined in JavaScript, which is generally tied to a JSBSim property.

 

Let's take as an example the needle from the vertical speed indicator used on this glider.

 

First, we have to properly name the object in question. In our 3D modeling software, we name the needle as BONE_needle_vsi. BONE_ is needed to tell the Outerra's importer (I use the FBX importer) that we need to access to that object via JavaScript.

 

Now after we successfully imported the model into Outerra, let's script that needle.

 

 

In JavaScript, I use this simple function to limit the rotation angle of our object(s).

function clamp(val, min, max){if(val < min) return min;else if(val > max) return max;else return val;}

And this one for converting from degrees to radians, together with the constant PI:

const PI = 3.14159265358979323846;
function deg2rad(angle_deg) { return (PI / 180.0) * angle_deg; }

Inside the function initialize(reload){}, we get our object(s) from the package for posterior use. As you can see, BONE_ is only needed for the importer. The real object's name is needle_vsi.

function initialize(reload){geom = this.get_geomob(0);jsb = this.jsb();

   needle_vsi = geom.get_joint('needle_vsi');
.
..
...
....
}

Now, let's proceed to animate this needle. This code needs to be written inside the function update_frame(dt){}

function update_frame(dt){
   val = jsb['velocities/v-down-fps']*2.55;
   geom.rotate_joint_orig(needle_vsi, clamp(deg2rad(val) ,-0.75,0.75)* PI, {x:1,y:0,z:0});...
...
....}

jsb['velocities/v-down-fps']  is the property used in JSBSim for the vertical speed. Then, I multiplied that by 2.55 to match the needle with the background texture.

 

 

Use this code under function update_frame(dt){} to print and show the vertical speed in real-time on console('P' key) . It also converts from foot per second to meters per second. This will help you to know how much you have to multiply jsb['velocities/v-down-fps'] in order to match the needle with your background texture.

this.log_inf("m/s  "+jsb['velocities/v-down-fps']*0.3048);

So yeah, that's basically what you need to do in order to animate gauges, and not only gauges, but any other object. You can always check out the scripts from any other plane and see how it was done.

 

I hope this is understandable, because I'm really bad when I have to explain things, and English not being my first language... 

 

Thank you for the detailed answer Levi!

 

I guess i'll also post here that the ASK-13 has just received an update. Please re-download!

Edit: Ah HiFlyer, you were faster than me! 

Interesting!  B)

Not bad at all. Obviously still a very long way to go but this is a definite few steps forward.
