Code:
world/New() 
    sleep(1)
    for(var/mob/M as mob)
        sleep(65)
        if(M.renting)
            M.money -= M.rent_price
            if(M.money < 0)
                M << "You cannot pay your rent([M.rent_price]), you are evicted!"
                M.house = "None"
                M.renting = 0
                M.rent_price = 0
                M.credit -= 10
            else
                M << "You pay your rent of [M.rent_price]"
    sleep(100)


Problem description:

runtime error: Cannot read null.renting
proc name: New (/world/New)
source file: Sims.dm,169
usr: null
src:
call stack:
: New()

line 169 = if(M.renting)

I think its my for proc, havent used it before but I'm making a simulation type game so it would really help to figure out what is wrong with this.

world/New()
    ..()
    //add stuff here


If ..() isn't called, the default action won't be called.
