Question about slider joint

[Witek900]

I want make a Body moving along along some axis. I thought about using slider joint, but i have read that joints can be attached only to non-zero mass Bodies. So how to create this kind of joint? It's very important, because i need to create sliding doors.

Any dynamic body can be attached to any othe body with any kind of joint.

when i doudt ask here, there is a lot of mis-information about the Newton SDK out there, primarilly from gratuitos self appointed Engine Apraisals with an interest in promoting other libraries.
