      how do you access the models that show up from raycasting. I dont see any documentation on it.

      if member(1).modelsunderray=member(1).model(1) then

       

      this doesnt work but again I see no documentation covering it

          In the 3D: Controlling action section of Adobe Director Basics, you can visit the section on Rays. On the Rays page, click on the right arrow to see four additional articles, including a short tutorial and a demo movie.

              Umm... I think that you will find that it says a lot more than how to display them in the message window.

               

              I am, of course, assuming that you know how to download the demo movies so that you can study them. For example, you can execute the following line in the Message window:

               

              go movie "http://www.adobe.com/support/director/examples/AirHockey.dir"

               

              This will open the demo movie for you on the Stage in Director, and you will be able to study all the scripts. In particular, you will find this handler:

               

               

              on GetImpactData(aMember, aPosition, aDirection, aBarrier)

               

                vRayInfo                     = [:]

                vRayInfo[#maxNumberOfModels] = 1

                vRayInfo[#levelOfDetail]     = #detailed

                vRayInfo[#modelList]         = [aBarrier]

               

                vRayData = aMember.modelsUnderRay(aPosition, aDirection, vRayInfo)

                vImpactData = vRayData.getLast() -- VOID if no barrier detected

               

                return vImpactData

              end GetImpactData

               

              I am also assuming that you know how to experiment and explore, and extrapolate from the examples that you can find to create code that fits the custom specifications of your own project.
