Im trying to make it like there is a pole holding two rigid bodies together, so that they are completely locked together. That code above is what i thought does it.. but i cnat get it to work :\

;make 2 rigid bodies called rb_A and rb_B then...

joint=TOKJOINT_Create(2,rb_A,rb_B)
TOKJOINT_SetType joint,3

That will glue two rb's together.

I need them to always stay a fixed distance apart


Rob(Posted 2004) [#4]
They do. You must be doing something wild and zany.


aCiD2(Posted 2004) [#5]
hmmmm...think i am :)
any chance of a demo bit of code?


Bot Builder(Posted 2004) [#6]
So, all you want to do is have the boxes be as if they were the same rigid body? Just do this:
Global rbCube = TOKRB_Create()
TOKGEOM_SetPositionAndRotation TOKRB_AddBox(rbCube, 2, 2, 2),0,-3,0,0,0,0
TOKGEOM_SetPositionAndRotation TOKRB_AddBox(rbCube, 2, 2, 2),0,3,0,0,0,0

No can't do that bot. This is for a cloth engine, so I therefore need to get the positions of a rigid body (one on each verex). This post should clear up some issues:
