"Hi, If you want to program forloops without custom scripting you should refer to Hoopsnake. The code in your referenced link should be inside a C# script component, I can't spot the relevance to your problem though. I am sorry I…"

draw helix trough several point, and loop problem

Hi alls !End of the week end !! No solution , I give up  and post on the forum ! Thanks for advance !!Here my problem: ( please found attached 3DM file and GH definition).I have  one curve and one point ( called reference point).I draw a Z axis helix passing through the reference point.I divide the curve by a number i of division.I would like to draw similar ( same nb of turn , same pitch, same axis Z) only radius, Zoffset and 'offset in turn' need to change.My two issues: For i fix (i =nb of…See More

Daniel Piker replied to Fred Pieri's discussion How to apply force fonction of the time F(t) in the group Kangaroo
"Try the attached definition. I've used the Kangaroo counter component, and a conditional so that the strength of the attraction force is normally zero but becomes high for an instant whenever the counter reaches a multiple of 50."

How to apply force fonction of the time F(t)

Hello all!I'am looking for define a force function of the time ; F(t).I have a system, let's says a triangle, with 3 forces ( Fa,Fb,Fc) it is in equilibrium.I would like Fb have a Dirac delta modulation.(http://en.wikipedia.org/wiki/Dirac_delta_function)Like a shock in fact!I know that is really hard to make a model of a Diract delta force.But at least it is possible to have Fb=2*Fb for 1 seconde? or x seconde.My goal is to study…See More
