why does this simplistic blockset Not work?

?
The blobs code not the other...

Can you check if the collision is detected? They may be set as simple physics or wrong collision groups. Put print block in the second code and check log viewer

Ok. I see whats going on, but I don't why.
If in the Actor Group, it works - I put to actors in  a group I named "Blobs,"

If in the Actor Group, it works
If I  put the actors in the Blob's group, they will not weld. I do not know why.

What?

What?... You can create groups. Some defalts are, Actors, Doodads, Players.
I created a group called blobs.
If I put the actor in the  "Actor Group, it works.
If I put the actor in the  "Blob Group, it does not.

Because it works only on Actors groups. I said it in the previous topic.

The first code create joints only if the actor in a region is an Actor group, not blob. Simply change first code and choose Blob instead of Actor

I already have that working...
I'm trying to figure out how to have certain groups weld to certain groups rather than All Actors.
I need some separation of types.

I need actors to weld to actors

I need blobs to weld to blobs

I need stems to weld to stems
