UDF dynamic mesh problem!
 

I got a code that functions like make one point oscillated, so the rest of the node will move along with it.

the coordinate of the point which oscillate must be (0.987,0) and the oscillation direction is X direction

if the coordinate of the point changed to (0,0.623),the the oscillation direction changed to Y direction, how can i change the code? I don't know C or C++at all.Any one know how to do it?

thx~

In other words，if I want to make one point of the dust cap oscillate and the axis stretching how should I write the UDF？
