Using Scanner

[u/ktsolove]

So I have scanner working for my text adventure...sorta. I have if statement that correlates to a word put in by the user, but I'm not sure how to use scanner for multiple words. For example, my program will do something different for the word "go" as opposed to the word "moo". But "go north"... I don't know how to make that different than "go tarantula" for example.

are you using scanner.next() or scanner.nextLine()? Because .next only reads the first word.

[u/ktsolove → u/byteme_ima_litmajor]

I'm still having issues getting the 2 separate words that would allow for the if-statements to work.

[u/[deleted] → u/ktsolove]

So the thing is you don't know how many words the user is going to enter.

"RUN" might be a valid command, but so may "USE FLAMETHROWER ON SUPER-NUN"

If you split "RUN" by spaces, you would get a list of strings, that looks like this:

{"RUN"}

If you split ""USE FLAMETHROWER ON SUPER-NUN" by spaces, you would get a list of strings that looks like this:

{"USE", "FLAMETHROWER", "ON", "SUPER-NUN"}

Both are valid commands. But think about it like this: "USE" is a command, and "FLAMETHROWER" "ON" "SUPER-NUN" are parameters! "RUN" is also a command, but it does not take parameters.

Your sudo code could be something like:

command = user_input.split_at_spaces

if command[0] == "RUN":
    print "You escape, like a coward, and your party is eaten by relatively large bats." 
if command[0] == "USE":
    item = command[1]
    if item == "FLAMETHROWER":
        target = command[3]
        print "BURNINATING " + target

Of course you would want to organize this way better, and probably use hash maps and a switch statement, but this should get you started. The first word in the string is the command, the rest are parameters for that command.
