| Post subject: | Reading Text Files |
Hehe half my posts are me asking for help... Anyway I saw a game where every class of the RPG had its stats or w/e written down in text documents which turing read. Sooo I set to reading the tutorial on it but all it did was give me a head ache  I read it like 30 times over and tried to do exactly what it said but it still didnt work. Anyways is there anyone here who could explain to me step by step how you would get info from a text doc for lets say... an item used in a game. |

Only 30? That's no good. Anyway, please post up your code so we know where to start. It's not use anyone giving you 'step-by-step' instructions starting from the definition of a variable downwards if you already know that stuff. Conversely, starting from the definition of an input stream might confuse you too - it all depends on how far you've progressed. We'll only know this from your code. As for the Tut by Dan, I don't see anything wrong or confusing with that Tut. It's about as step-by-step as you can get! |

LOL, just deleted all the code cause i figured i must have done something wrong a couldnt find, so i was gona try and start over from scratch, anywho his tut wasnt confusing andhad enough info its just when I tried to do it i could never get it to work... This is basically what i had before:
I know im missing something but ive never done this before so i cant figure out what i am missing  |

"nums" is the variable that you are assigning the information you are getting from the file, therefore you need to declare it before you can assign it any information |

OOooo... Ok now I see before i thought maybe you put it in your document to say what turing picksup or something... Now when I look back at his final code in the tut i see why he dosnt have it in the variable list *bonks self on head* he switched it for numberofmarks... haha |

k lets say i made a text file or data base for an item nad recorded stuff like strength, weight, damage, etc. How would turing know which line of the text file to get that from? |

Many ways. If you had each systematically on seperate lines, then you'd just read each line into a seperate field of a record. If they were all on one line, you'd simply parse them into the record. For instance:
This might represent First_Name, Last_Name, and Age. As you can see, they are nicely ordered, and can each easily be read into a seperate variable.
Notice that you'll have to figure out how to determine whether each line constitutes as '1st', '2nd', '3rd', or 'nth' - depending on how many fields you have. This is likely easier than parsing, but only marginally so. |

you could also look into the seek command, which goes to a line specified by you in a file for you to take information etc  |
