Extended Controls

<< < (2/3) > >>

zzz:
I'm having trouble with the air/controls section. None of them seem to register.

this.register_event("air/controls/elevator", {minval:-1, center:1000, vel:1000, acc:1000}, function(v) {
this.log_inf(v);     
}

With car controls and airplane weapons it shows me the value of V but not with air controls.

Uriah:
Try:

1. Declare a global variable named test_var
2. Assign v to test_var in the register_event function
3. log_inf for test_var is update_frame

Uriah:
Also, there is a problem, syntax error unexpected identifier, because you didn't close the method.

Fixed:

--- Code: ---  this.register_axis("air/controls/elevator", {minval:-1, center:1000, vel:1000, acc:1000}, function(v) {
    this.log_inf(v);
    test_var = v;
  });
--- End code ---

});

I am able to log_inf from inside other register_axis or register_event methods functions perfectly fine. Also, for something like elevator controls, you would want to use register_axis method. Register event would be used for switches, like opening and closing a door, lights, etc... register_axis is used for controls which have a range of input stages, such as a joystick axis.

Uriah:
You can also assign jsbsim properties directly inside the register_axis method:


--- Code: ---  this.register_axis("air/controls/elevator", {minval:-1, maxval:1, vel:0.1}, function(v){
    this.jsbsim['fcs/elevator-cmd-norm']=v;
    test_var=v;
  });
--- End code ---

zzz:
no, none of those are working. I can get Canopy to work, but any buttons with + and - next to them in the controls don't register at all.
