How to delete dynamic points by group

[Gabriel_Wolf]

Hello,

I made a rigid body simulation where I have different kind of pieces, like pavement, road etc. I grouped them in a group called "group1"

How can I write this in vex in pointwrangle?

Take the group1 and if the points in group1 are under  -1 in @P.y then delete them.

 

Thank you for your help

hello,

there are many ways to do that, but I would say one easy way is to have a point vex wrangler, set parameter "Group" to group1 and in the code section, write something similar to 

if(@P.y<-1)

   removepoint(geoself(),@ptnum)

cheers
