Club Scene help

Can someone help me with doing a larger club scene? Best way to spot characters? How do I keep them active? How do you do the flashing lights? Ink style and the background I am using is the INT. Rock Nightclub. Any help would be much appreciated!!

There are animations that are looped, so if you want them to do something in the background, you use “&” rather than “@“.
An example would be:

&CHARNAME starts dance_phone_raise_loop

rather than

@CHARNAME starts dance_phone_raise_loop
