I'm not sure if this is even possible and I'm sure my code is probably completly inane, but how would I return variables to a proc from three levels in?
e.g.
mob
proc
proc1()
do stuff
proc2()
proc2()
do more stuff
proc3(something, another, one_more)
proc3()
do even more stuff
variable1
variable2

Are you talking about this? /mob proc proc1() do stuff return proc2() proc2() do more stuff return proc3(something, another, one_more) proc3() do even more stuff return variable1 verb do_stuff() world << proc1() The above code (assuming it was actual code) would print the return value of proc3 to the world. When you return from a procedure, you can use the return value (which goes in the place of the procedure call) just like you would any other value--you can assign the value to variables, use it in if statements, and fortunately for you, use it in return statements. | |
proc3() How would i return variable2 also? [EDIT] I'm guessing I could do this in a list and then return the list which can be broken down later, but if there is a better way, please let me know. [Again] That seemed to work, but how would I then use the results from the list and save them as variables in proc1? | |

proc3() Hrm... that depends on the situation, I think. One way, if variable1 and variable2 can be found more or less separately, you should just use different procs. Even if one variable depends on the other, it's relatively easy to use separate procs to find each: /mob proc proc1() var/a = 2 return proc2(a) proc2(b) return b + 2 proc3(c) return c + 5 verb do_stuff() var/c = proc1() world << c world << proc3(c) The first output line will display 4 to the world; the second will display 9. If you really need to get the values for two variables and don't feel like separating the procs you use to get them, you could make a list with the values: /mob proc proc1() var/a = 2 return proc2(a) proc2(b) var/c[] = list() c.Add(b + 2) c.Add(proc3(b + 2)) return c proc3(d) return d + 5 verb do_stuff() var/c[] = proc1() world << c[1] world << c[2] I'm pretty sure that would do the same thing as the above example. Lastly, if variable1 and variable2 and a few other associated variables are ones that you need to use in sets a lot, you might want to define a datum type to handle the information in sets: /thingy var a b proc proc1() a = 2 return proc2() proc2() a = a + 2 b = proc3() return src proc3() b = a + 5 return src /mob verb do_stuff() var/thingy/T = T.proc1() world << T.a world << T.b This does the exact same thing, but it's an incredibly silly example... come to think of it, they're all incredibly silly examples. I'm guessing you're probably looking for something along the lines of the first two examples anyways. | |
not sure, but maybe ..() would work.
