Combining sketchy physics joints

ashiboy

how can i combine 2 or more joints like a motor and a piston or isn't it possible?

example: a cube spins and can go up and down while spinning

thank u

Hey!
I don't think it works just with a motor and piston conected to a wheel.
But if you group a motorjoint together with a box, and then connect the piston to the motor-box-group, then it will work.
Here is a skp-file with a simple example:

wheel and piston.skp

P.S. if you don't want to se the box just right-click and hide it...

hope this is to some help.

is there a way for the box to be like a ghost i mean when u put a falling object above the (hidden)box and it goes through

Yes.
Go in to the group with the box and motor, then right-click on the box --> SketchyPhysics --> State: ---> then ether "ignore" or "nocollision", it dosn't matter right now.

And if you don't want to se the box after this ignore stage, just "hide" it under right-click-menu.
