I have an observe verb:

Observe()

if(!ingame)

var/list/Playerz = new()
for(var/mob/Player/P in world)

Playerz += P

var/mob/Player/P = input(src,"Chose someone to observe.") as null|mob in Playerz
if(!P)

return

else

src.client.eye = P
src.client.eye = P

I get the list of players an all, but when I choose one, my screen goes black. Any insights? Thanks.
