      Pivots and springs work normal in it.

      Normal being what, exactly?

        @Deeeds normal is defined as,

        Sorry, I should have used a more common, understandable word......

          @iTap-Development Your original claims, and the ones I'm taking issue with, are that spring joints and pivots are working fine, and your new claim that they're normal. They're not fine, not normal, and their issues are indicative of the problems the OP is suffering, and of a fundamental problem in how physics operate within hyperPad.

          @Thecheater887 is having real problems with the physics system. Symptoms of the problems that cause these issues permeate through all of the joints in the system in different ways. Springs are the best indicator because they're more than the other joints (not really joints/constraints) and have a couple of glaring issues.

          One of them is damping. Damping, ironically, is the only part of a spring joint/constraint that can be considered a joint/constraint.

          Just because you're not noticing and/or unaware of what these issues are doesn't mean anything is fine, or normal, or that spring joints or pivot joints or any other specific thing is working as it should. They aren't.

          The pivot joints, by way of exact example, exactly mimic the problems @Thecheater887 is seeing with weld joints because they share the same assumption: that they'll provide a fixed location of a rigid connection between two bodies. Yet neither of them provide this.

          Just because you haven't noticed this doesn't mean that pivot joints are fine, or normal.

          Pivots and springs work normal in it.

          Wrong.

            Collisions, though, play havoc with the physics engine. For whatever reason, areodynamics are potato, causeing non-rectangle or circle objects to spaz and jerk in usually one direction. I'm assuming this is because of the uneven collisions and Air Force (resistance?), yet we have no way to fix this, especially if it isn't.

            Do you have joints connecting any of these bodies to any of the other bodies?

              Wrong.

              Did you look at the project? And if you did, you would see they work fine, normal, correctly, and any other word you would like.

                A quick lesson in booleans, since you’ve probably missed these having grown up inside only hyperPad:

                I know I’m not an expert in this area

                TRUE!

                you would see they work fine, normal, correctly, and any other word you would like.

                FALSE!

                  Haha. I know what Booleans are. Hyperpad isn’t the only thing I’ve used, but it is the main thing.

                  So, you know what I know about myself is true? You are brilliant!

                  Did you play the project? I have to assume you didn’t.

                  if deeedsknowseverything == stupid then
                      print("iTap is right") 
                  end

                    @iTap-Development No. It's not quite that simple. I'm wrong just as much as the next person.

                    However, you don't know what you don't know about springs and pivots. You're testing them in ideal scenarios and overlooking their flaws, and you are unaware of how they're expected to behave, should behave and designed to behave.

                    And you haven't acknowledged, nor are you helping with the OP's problems.

                    In fact, the opposite is true. You're distracting from his very real problems, which I've been wasting my time trying to reassert are real, to you.

                    You seem to have missed all of my points in this failed endeavour. Perhaps you'll believe @Hamed, who said this about his implementation of Chipmunk and other things...

                    So, when we made the migration from Box2D to Chipmunk, we kind of fudged the numbers of some stuff to get it as close as possible so that old games were still supported.

                    All this being said, theres a bunch of stuff broken

                      @Deeeds wait, in the other thread you said “Like you tested spring and pivot joints?”
                      Now you said, “You're testing them in ideal scenarios and overlooking their flaws”
                      So am I testing it or not? Make up your mind lol

                      Let me guess, you used to be indecisive, but now your not so sure?

                        Ok so the bug has been reported.
                        We'll be changing how we do physics by giving you more "raw" control and less "magic" behind the scenes.

                        Closing this thread since it's going way off topic and makes it harder for us to actually find problems in between these discussions.

                        Use the general discussion section to continue this discussion if you want :).
