    Looping symbol swap

    michael_godfrey Level 1

      I am a graphic designer and rudimentary coder at best, so I apologize in advance if this should be a no brainer.


      My goal is to display random repeating tile patterns that overlap.  The original files are .png format with transparency.  I wish to show how they fit within a pattern building system that allows for multiple combination options.


      To keep file sizes down, I tiled each of the small png files to fill my stage and converted them to symbols.  They fall into two symbol groups: Pos and Neg with a number sequence after.


      What I'd like to do is have one Pos and one Neg display and change randomly on a loop. With the hundreds of different symbols, this would show a massive amount of possible combos.


      I searched for a solution and the best I could find was this: "Call random symbol" https://forums.adobe.com/thread/1110407?start=0&tstart=0http://

      i am not sure how your composition is but let's assume that you have symbols named symbol_1, symbol_2 etc...


      You can append them randomly to the stage as follows and play their timeline.


      var myVar = Math.floor((Math.random()*6)+1);


           var stage = sym.$("Stage");

                var myAni = sym.createChildSymbol("Symbol_" + myVar, "stage");






      This seems like a good starting point.  I tried it almost as is by adding the code to compositionready for my Stage.  I changed "Symbol_" to "Neg" and it didn't show anything in the browser.  As such I have a few questions:


      1. This solution appends the Stage.  I eventually need to place two random symbols.  Should I be targeting something like place-keeper rectangles vs. the Stage?

      2. The Math.random()*6:  I'm guessing the 6 is replaced with the number of symbols in each category and the +1 is because 0 could be generated?  Does that also mean that the total of 6 should be one less than the entire total?

      3. When naming a symbol library that goes into double or triple digits, for coding purposes do you leave off the zeros in Neg01 or Neg001?

      4. And finally, is there a better or easier solution than this for what I want to do?
