Mouse and mousestate, how to use them?

I’ve seen a couple of videos in which a lot of particles seemed to follow the mouse. Then I’ve found out that there’s a node called mouse and another one called mousestate. However it seems that there must be something between these nodes and the renderer- the pins cannot be directly connected! What am I missing?

Don’t bother, just found out!
it’s just mouse-transform-quad-renderer. You link mouse’s first (lowest) pin on the left to translatex and translatey in the transform node
