Parameter values using VEX function

[Guna]

Hello Everyone,
Can anyone explain how to set parameter values using VEX function?
Say for example,there is a sphere, scattered. If the current frame is between 5 and 10, the number of scatter points should be 10 else 0.


if(@Frame >= 5 && @Frame <= 10)
{
@scattercount=10;
}
else
{
@scattercount=0;
}

How to set @scattercount to force total count parameter of scatter sop.

Thank you.

Hi! You could reference a wrangle node with this expression:

detail("../detail_wrangle","scattercount",0)

Attached is the complete solution.

you can also use hscript directly in the parameter field:
if($F>=5 && $F<=10,10,0)

Hi ... Thanks for the replies. Both the solution works fine.

Similarly, how to use a value from vop to set parameter values?

As regards the technique that I have posted ... it doesn't matter if the detail attribute was created in VEX or VOP. I attach the updated version with VOPs.
