POP Drag: Spin
- [Instructor] Alright, I'm gonna rename this popdrag node to popdrag_nage so we can clearly know which node is doing what. Bring the popsolver down a little bit again. And now I'm gonna right-click at the end of this node, and do a popdragspin. And because, you know with this project we are actually concerned about how these things are rotating around, because we're gonna be having actual pieces of geometry that are instanced onto these points, it's easy for the simulation to get a little bit out of control, and have things spin too much, so this is basically just a drag on the rotation of the object. So now what we're gonna do is we're just gonna open this one up and go under VEXpressions, and before we've been using the errorresist attribute, and if you see if I click on this, you see that spinresist is the spin resistance. So I will type spinresist. And we will do *= Fit01(@nage,0,5) So we're doing a similar thing to the popdrag over nage. And then this is giving us a little…
