System Name for Array Index Numbers?

I’m trying to integrate Blade Detect with my Array Selector such that an array named NO_BLADE gets ignored when switching array manually, but will still be switched to when Blade Detect tells it to.

But I don’t know what the system calls those index numbers.

I’ve updated my regular code from this:

    struct SabersenseArraySelector {
      static int return_value;  // Tracks current array index.
      float id() {
        return return_value;
      }
      static void cycle() {
        return_value = (return_value + 1) % NELEM(blades);
      }
    };

to this:

struct SabersenseArraySelector {
  static int return_value;  // Tracks current array index.
  float id() {
    return return_value;
  }

  static void cycle() {
    // Skip NO_BLADE array during cycling
    int num_blades = NELEM(blades);
    do {
      return_value = (return_value + 1) % num_blades;
    } while (blades[return_value].id() == NO_BLADE);
  }
};

but the system is complaing that id() isn’t recogised. I also tried ‘index’ but that didn’t work either.
So does ProffieOS have a different name for those numbers?

Thanks in advance.

I think your first code block is already the same as the changed-to version.

Anyway, maybe you could just do something like:

static void cycle() {
  if (return_value == NO_BLADE) {
    return_value = (return_value + 2) % NELEM(blades);
  } else {
    return_value = (return_value + 1) % NELEM(blades);
  }
}

?

Oops. Sorry. Now corrected.

They are called “ohm”:

And NO_BLADE is just a number:

also, you should check if ohm is NO_BLADE or larger, so like this:

  do {
     i  = (i + 1) % num_blades;
  } while (blades[i].ohm >= NO_BLADE);

If you then set return_value to blades[i].ohm, then you can avoid having to set the ID to 0, 1, 2. etc. (Of course you’ll also need to map return_value to an index at the beginning of cycle().)

Thanks guys! This is great. :smiley:

I’ve added your solution, Prof, and it’s working well, but I don’t have a Blade Detect hilt to test it fully. The good news is I have one on the bench that will have have BD and should be finished shortly. As soon as I’ve tested all aspects, I’ll update my prop and submit a PR to include the new Array Selector/Blade Detect functionality.

Thanks again. :pray: :slight_smile:
