I can't figure out how to make environment joints and don't know what mass doesn't keep you from swinging the object.

For the joint issue, check out MrPoptart's modding tutorial...
As for the mass, try something between 0.005 and 0.0001...

I know the way you get them started,it's getting them to stay connected that's the problem.

it should never be able to disconnect unless you used dmthreshold...

does the location of the joint is important?

yes. VERY important, that takes the longest part, getting the location right
if youd want a ball to spin, the location needs to be the location of the ball, and if ud want a pole attached to it like in a piston, youd need to set the location at the outer part of the ball and the end of the pole, takes me about 20 mins sometimes, if i used alot of joints

hmm i keep wondering im trying to make a Tank out of wheels. (T.O.W. for short) but it keeps on destroying itself. I put the joints in place but no movements, no hold, no anything. How am i suppose to fix it?

Ok what if we're trying to make a fancy weapon how would joints be placed?

my guess is at the point were 2 objects meet so it sticks thoughether there and basher, im not really sure what you mean, you can try to pm the mods that dont work to me and ill see what the problem is
