Hey guys, I don't know if It's possible to create a single gear character in buildbox whereby the collision shape is just like it's physical shape. I've tried Linking a circle and boxes but using physics makes it dangle and loose shape Using platform makes not interact with the floor to
I suspect the best you can hope for is a gear image with polygon collision shape that's as near as you need, You can make an eight-sided shape so it could work to cover a small gear where the concave parts wouldn't be large enough to be evident.
You have the right Idea. Make your character the main object and connect it to the other objects. make the objects fixed object while your character is physics
