I have to simulate these platform system (hinged together) moving (sliding on the floor) from Position 1 to Position 2 by using SLIDER. The front part should automatically change its position by crossing the hump on the floor based on the bottom geometrical form (always tangency with the barrier).
Hi, sorry I didn’t see this earlier.
I think the collision prevention is best tackled in 2d, since there is no movement in the other axis.
The curved part needs to be divided into straight segments, since currently the 2d collision is only between polylines. We keep the lower polyline fixed, then we can move the hinge point along a horizontal line with a slider to drive the movement: slide_collide.gh (22.0 KB)
