Code:
mob/var/isfish
mob/var/fishchance
mob/var/catch

mob
    verb
        fish(mob/M in view(3))
            set name = "cast out"
            set category = "Fishing"
            if(M.isfish==1)
                usr.fishchance=rand(1,3)
                if(usr.fishchance==3)
                    usr<<"The fish gets away!"
                else
                    usr<<"The fish goes for the bait!"
                    usr.verbs+=/mob/verb/reelin()
                    usr.catch="[M]"
mob
    verb
        reelin()
            set name = "Reel in"
            set category = "Fishing"
            usr.catch(step_towards(usr))
client
    North()
        if(usr.fishchance==1||usr.fishchance==2)
            step(usr,NORTH)
            step(usr.catch,NORTH)


Problem description:
well for some reason the usr.catch(step_towards(usr)) line
gets 2 errors and i dont get what is wrong with it.
errors:
fishing.dm:24:error:usr.catch:undefined proc
fishing.dm:24:error:step_towards :expected 2 arguments(found 1).

Look at the error. catch is not a procedure, yet you are trying to use it as such. You have define catch as a variable, though. This will help you out a lot.

mob/var/fishchance
mob/var/fish/catch

mob/fish
    icon='fish.dmi'
    verb/fish()
        set name = "cast out"
        set src in view(3) //Only use if it's within 3 spaces
        set category = "Fishing"
        if(prob(66)) // 2/3 chance of catching
            usr<<"The fish goes for the bait!"
            usr.verbs+=/mob/verb/reelin()
            usr.catch=src //Set the fish that the usr is catching to this fish
        else
            usr<<"The fish gets away!"

mob
    verb
        reelin()
            set name = "Reel in"
            set category = "Fishing"
            step_towards(usr.catch,usr) //this is the proper format for step_towards()
client
    North()
        if(usr.fishchance==1||usr.fishchance==2)
            step(usr,NORTH)
            step(usr.catch,NORTH)

I think this should work. You shouldn't use variables like "isfish" when there's a perfectly good type system in BYOND :P
