Ok then! I'm almost there

What I'm doing: created a level with an array of tiny triangles shaping a sphere (as if they were vertices). In the script, I created an additional triangle entity called pivot and positioned it in the center of the sphere. All the other triangles have the same action applied, so they are now physical objects and are constrained to 'slide' in the axis defined by the pivot.

Problem: Inside this action, the line: phcon_add(PH_SLIDER, pivot, me); is causing trouble... without it, the program runs nicely. everything falls down just like we would expect. But with this line, the software still runs with no error message at all! But with no physics. Everything just stands in their initial position. (even additional test objects don't move!)

I assume that command line is wrong. But then, how can I add a constraint inside an action to all those triangles, so they all move accordingly to an extra triangle (pivot)?
