      VPX physics have come a long way in the past two years.  Authors have been optimizing settings and have produced amazing results using different methods.  I personally have been very happy with a wide variety of physics by different authors and often study what different authors are doing.  As a result of those studies, I’ve found nFozzy’s physics to be the closest to real pinball.  He’s done some pretty amazing work that extends the physics capabilities of vpx!

      nFozzy’s Terminator 2 and Space Station are great example tables of what his physics can do and how he’s implemented some of the methods I will walk through.  I encourage you to dig into these tables if you’re interested in what he’s doing.

      I’ve posted part 1 showing how to implement nFozzy’s polarity and velocity correction for flippers.  I will be posting two additional tutorials in the next week or so with a somewhat complete guide for his physics.

        Part 2 has been posted.  It includes instructions on how to use nFozzy’s enhanced elasticity curves for rubber posts, rubber pegs, and rubber sleeves.

            In part 3 of this tutorial I walk through some of the general physics settings used in nFozzy’s Terminator 2 table.  In combination with his flipper physics and rubber elasticity extensions, these settings are a great starting point for building tables with outstanding physics.  While most applicable to new tables (90’s and newer), these can also be used effectively on early SS to late 80’s tables with some minor tweaks.

              This is really great stuff especially for beginners like me.  Thanks for explaining this as simple as possible :good:

                I setup my flipper trajectory table to compare normal VP flipper physics to the nFozzy flipper physics.  Nfozzy physics are the sharp arrows, VP physics are the fuzzy arrows.

                  I added these the other day to my current wip, definitely different on the flipper feel, I had played the table enough I had the shots pretty dialed in, had to re-learn them lol

                    I’ve updated the nFozzy physics tutorial to include the settings and code to implement the flipper tricks physics and a few minor tweaks I’ve made to the original recommendations.

                        I’ve updated the flipper physics tutorial with the latest code and profiles.  This has been stable for 6 months now.
