Well, I was just wondering if setting up multiple rooms using modules would be effective. I know that procedures would be impossible to do, because they procedures have to be in a certain order, which could not happen. For example, if I load room 13, and then move to room 14, the procedure for room 14 will be above room 13. However, once I get to room 14, and want to move back to room 13, the procedure for room 13 would have to be above room 14, so it would be an impossible arrangement. So if modules aren't the solution, is there anything else I can do? Thanks.

hardcoding anything is generally bad practice... unless you want to hide some information, but then there's encription... Anyway, the solution would be to load dynamic rooms from the file and basically generate the room as you walk into it. Upon exiting a room, a variable is read from the "door" part of the room that tells which file contains information about the next room. That file is then loaded and text information read such as size, location of objects, doors, etc. Those values are loaded into variables used to store active room in the program and suddenly you appear in a brand new room Dan wrote a tutorial on how to read/write from a file in the tutorial section if you need help with that.

I'm having some trouble following what you are saying. Can you give me a basic example of what my code should look like?

hmm... well lets see how your organize your room procedures? Try to put all the variable values in the textfile and then load it up... if you're having trouble, post one of your procedures and I'll try to help you.

Well, if I tell Turing to load a certain file with Turing commands in them, will they run properly? Like for example, I make a file called "test". I open it up, and type in put "hi" in it, close it and save. If I go into Turing and get it to read the file, will it actually follow the instructions?

no... thats what include does. And when compiled, it will paste the code into the place of the include (I think you can crash the program if you make a loop out of includes).

What you need to do is load the variables. Such as if you know that the text you want to display is the first line of the file, then you do something like

code:

get : fileNum, text:*
put text

ofcourse you need to properly open the file first, read tutorial for more info Wink

Basically the file only contains text information. You need to write some code that can read that information and make sence of it. Such as if you don't know what the varaible is suppost to do, you can put additional "help" word that your program will ID

code:

get : fileNum, helpword
if helpword = "put" then
get : fileNum, text:*
put text
end if

in this example, the program reads first word on the line and if it happens to be a command such as "put", it will put the text that follows on that line.

I suppose to can write your own vertual compiler in turing to actually run the code. You're going to have a hard time accessing variables though.

Ah okay, thanks, but I just figured out my own way, while I was gone . So now, I have a way for it to move in between rooms, and I already have 5 rooms set up. As soon as I finish 25 of them, I might wanna post it here.

can you give more of an example of how include works?

include basically copy/pastes the code from the file into your program. This works much like C/C++ header files where you save functions in an outside file and include all the content of it with a single line. In theory, if you have couple of files including eachother in a circle, it should crash your program as it will become infinantly long (remember, it includes the code, not referecing it. You should use functions for that)
