      So, i'm trying to build a cannon. now it rotates with a servo joint. i wonder if it's possible to throw out the ball with a piston joint after the cannon is rotated.

      Thank you in advance.

        A piston would certainly push the ball out. I don't know how you would trigger it tho. Maybe a hidden object that will hold it in until its in the right position.

          so, basically, i cannot make the piston joint rotate along with the cannon and fire when i want...

            The piston will rotate with the cannon. But it will fling the cannon ball as soon as you play the simulation.

              thank you so much! i finally got what i wanted!

              can i ask you one more thing? is it possible to make the cannon rotate on the blue axis with a wheel+servo joint?

                im not a sketchy physics user, but cant you rotate the modle to one side, apply the joint and then rotate it back? i just saw it on a vid, so mght well be wrong.

                  I had to explode and re-group the wooden parts. It was messed up somehow.

                      have a look at the completed model!

                        Check out this cannon that I made. It's self moving and quite realistic. Different reloading mechanism, hope it's intuitive.

                          nice! it's very powerful, though i found quite hard to understand how it fires...

                            Maybe you can fire some flowers and it will be perfect πŸ˜‰ 😎

                            Very cool engine πŸ‘

                              Showing hidden geometry and turning on transparency will reveal all secrets of the cannon.
