      Hi all,

      I am trying to find the right actor to interpret more than one value of "if then": I have 8 sensors each outputting 1 when on, 0 when off. I'm trying to find an actor that can do "if all 8 values are 0, then output 1 or trigger".

      I've tried the Lookup actor, but it doesn't seem to do what I want.

      I'm sure this is quite easy, but I can't seem to find the right actor for it.

      Thanks very much

          Hi @Skulpture,

          I need to compare 8 values though. If all 8 values = 0 then output 1.

          If there any actor that can compare more than 1 values?

          Thanks!

            this is quite easy: use four calculator actors for the input values, then another two to get the summary of two pairs and another one to get the summary from them. Then take a comparator actor that is looking for zero, if zero then the output is one otherwise zero. See attached image.

            Best

              Seems like an ideal place for the javascript actor.

              Also very minor bug report - it says compatator in the help for the comparator actor (see Skulptures post above)

                    Or paste the following into a javascript actor with 8 inputsfunction main(){ total=0; for (i=0;i<8;i++) { total+=arguments[i] } return total>0; }

                        The javascript method is great.

                        But another very simple one can be setup using the 'Lookup' actor.
                        It will output 0 if the 'compare' input is not found in the X (eight for this case) inputs.
                        Otherwise it will say which input matches the 'compare'
                        If your binary values run into eight value inputs, and you compare '1', you will receive a '0' if all of your eight values are not 1, and a value between 1 and 8 if there is a match.

                          Thats great too!

                          Another way - how about the Maximum actor with 8 inputs. 
                          The advantage of this is that the 8 value inputs are 'active' - with the lookup actor you have to keep sending '1' to the compare input every time you want the actor to do its thing.
                          Sorry if I'm getting a bit anal. On the same note here's a rewrite of the javascript:
                          function main()
                          {
                          for (i=0;i<8;i++) {
                          	if (arguments[i]==1) {
                          		return 1;
                           		break;
                          		}
                          	}
                          return 0;
                          }

                            yep the maximum actor is even simpler to setup.

                              yes,Maximum is an easier choice than lookup.
                              Its probably the easiest native Isadora solution.

                                I didn't know about the Maximum actor. this is so great! yes, the easiest solution! thanks so much.

                                    the tutorial on Javascript for Isadora might be worth a read.
