Code:
    check_wealth()
            if (usr.wealth -= 0)
                usr << "You have no Gold!.  Get out there and do something!"
            else
                usr << "You have [usr.wealth] Gold!"


Problem description:
Ok, I'm trying to get the my check wealth verb to tell the player to go do something if they have no gold, and so I thought about using an If, Else system to do so, but the compiler gives me a missing expression error. What should I change to make it work right?

-= basically means x = x - y.

The correct operators would be <= (less than or equal to.)

If your proc is simply checking to see if they have any gold at all and not a specific amount, just do...

check_wealth()
     if(wealth)
        src << "You have [wealth] gold."
        return 1

Thank you very very much! :)

Just thought I'd add for any future reference that while <= is good in most situations, you may find an odd occasion where you need to just use < and that's fine by itself.

In this case <= is correct.
