      So you want one of it in destruction, or while it's falling, well here it is. And I don't want my bridge to be the only one up here, so someone make another one please.

        No, you don't need to be scared, you're supposed to fix that and make it a working bridge. Like this one. And I'll add another rule to the list #7 You may make minor additions to the abutments.

        That is amazing! Very nice construction ArchitectBoy.

        I was going to do a arch bridge but yours is better. Maybe I'll try a trestle bridge.

          The toll for this bridge is going to be a lot of $.
          One time use :~)

            Wow... what a balancing act... I like it... To bad it violates rule #1, but otherwise I like it. And I revised mine, it looks a lot better now.

              FYI, You can make perfect arches if you use the convex hull shape. Here is an example:

                this is the kind of stuff I was talking about Chris... testing shapes and systems... now make glue for me... and sand and water and wind and... and... yeah I know, I'm really happy to just have this.... but I can still wish...

                  Thanks for showing me what "convexhull" does, with that info I have revised it again.

                    Very nice! It looks elegant and its really stable. I vote for this one. πŸ˜„

                      Ok, so I'm playing around with my bridge destroying it, throwing the car around, etc. when I come up with the idea of rendering the bridge, and once I had a nice render of it I couldn't help but make one of it destroyed πŸ˜„ .

                      These renders are pretty sweet. I assume it is Kerkthea?

                        Yep, that's Kerkythea (you forgot the y). Are you working on yours, CPhillips?

                          Convexhull:
                          Is this simply a cube (re-assinged to covexhull)and the form adjusted as necessary?
                          Forgive me if I have missed something obvious.

                            It doesnt have to be a cube. Any shape will work. The easiest way to imagine a convex hulled object is to picture it wrapped in plastic. Here is a more detailed explanation:

                            http://www.rustycode.com/tutorials/convex.html

                            If you want to see what the physics engine thinks an objects shape is:Right click the object and select Debug->Readback Collision Geometry. Then press play.

                                Hey guys,

                                This is my first time using this script, and I think i might not be adhering to all the rules of the program, but nonetheless here is my submission.

                                Thank you for this great program! I love it!

                                  The problem with your bridge is that it uses 18 static parts (see rule #3) which make it impossible to tear down the bridge (try it), those parts are the joints. Joints, by default, are static, but if you make them not static they just fall. So you must leave them static and group them with one of the objects that it is connected with. Just take a look at this revision of your bridge.

                                    oh cool, thanks for the hand! that makes a lot of sense now... I'll have to make a bigger and better bridge now...

                                      Go for it! and that goes for anyone else who wants to build a bridge for this contest.

                                        Not quite the same thing. But this guy did a bridge! πŸ˜„

                                          Hey, was wondering if this was a legitimate bridge. There are hinge joints inside the triangular prism blocks... They are attached to a couple of things to simulate being attached to another piece(s). I could make the whole bottom a box, but that's not accurate.
