Solve : Game saving trouble? |

Answer» Okay, hello! New here, hope you can help. mkdir %~dp0\testfolder Quote apparently the %~dp0 makes it the drive, the path of the file and name of running file the location, but this seemed to glitch out, making a folder called 'stuff' (the parent folder of current folder is called 'game stuff') with a subfolder 'My' ('My game' is the folder with the batch in.) also a folder called %mylastname%. and the console window said something about problems with the folder C:\Users\%myfirstname%(confidentiality). which doesn't exist, plus some others of similar weirdness. Standard variable MODIFIERS documented in the FOR help (type FOR /? at the prompt) %~I - expands %I removing any surrounding quotes (") %~fI - expands %I to a fully qualified path name %~dI - expands %I to a drive letter only %~pI - expands %I to a path only %~nI - expands %I to a file name only %~xI - expands %I to a file extension only %~sI - expanded path contains short names only %~aI - expands %I to file attributes of file %~tI - expands %I to date/time of file %~zI - expands %I to size of file %~$PATH:I - searches the directories listed in the PATH environment variable and expands %I to the fully qualified name of the first one found. If the environment variable name is not defined or the file is not found by the search, then this modifier expands to the empty string The modifiers can be combined to get compound results: %~dpI - expands %I to a drive letter and path only %~nxI - expands %I to a file name and extension only %~fsI - expands %I to a full path name with short names only These work not only for FOR metavariables but also batch parameters %0 (which is special, being the batch file itself) and %1 to %9 (passed parameters) So you can see that %~dp0 is going to expand to the combination of: %~d0 the drive letter (with colon) on which the batch script is located (NOT necessarily the current directory) %~p0 the folder path to the batch script is located I believe the issue you have is not security, it is spaces in the path. If the batch script is located in a folder whose path has any spaces, you have to use quotes so try mkdir "%~dp0\testfolder" I see you USED quotes later on when echoing to testvar.txt 90% fixed! Stupid mistake that was! Problem now is that it doesn't read the file and just comes out with the random number again. The random number was just to test if it WOULD read the old one from the file and to make sure it wasn't just repeating what had just been entered instead of the file. Now I see that it doesn't read the file. Help? thanks again!This is one way to read line one of a file. Code: [Select]set /p "testvar="< "%~dp0\testfolder\testvar.txt" >nulChanged a bit. Somehow more broken than previous. code: Code: [Select]@echo off echo initializing.... mkdir "%~dp0\testfolder" set /p testvar = Enter test variable here: echo Will now save your variable to file. echo %testvar% > "%~dp0\testfolder\testvar.txt" echo Will now set active variable to random. set testvar = %random% echo variable is now %testvar% echo Will now load variable from file. pause set "testvar" < "%~dp0\testfolder\testvar.txt" >nul echo variable was: %testvar% pause The result: initializing.... Enter test variable here:sdfvgbh Will now save your variable to file. Will now set active variable to random. variable is now //Noteing that it isn't displaying the random number. Will now load variable from file. Press any key to continue . . . variable was: //Also blank Press any key to continue . . . Oh dear.... Remember if anyone knows an alternate way to save stuff to file and then read it when the game is next run tell me :L Just need it explaining well and simply. I posted just before you. You aren't reading the file correctly, and I posted one method. set testvar=and set testvar =two are two different variables.So, what would be the correct code? I inserted your line you posted and put spaces between the ='s and such. that's what I posted just then. set testvar=123 echo %testvar% Quote from: gogglebot on December 07, 2012, 12:56:25 PM I ... put spaces between the ='s This is what you should not do! Batch scripting language does not ignore spaces, unlike many other languages. Alright, Salmon you seem to better explain things rather than throw bits of code at me. What lines and such specifically need changing? Thanks@echo off echo initializing.... mkdir "%~dp0\testfolder" set /p testvar=Enter test variable here: echo Will now save your variable to file. echo %testvar% > "%~dp0\testfolder\testvar.txt" echo Will now set active variable to random. set testvar=%random% echo variable is now %testvar% echo Will now load variable from file. pause set /p testvar= < "%~dp0\testfolder\testvar.txt" echo variable was: %testvar% pause Quote from: gogglebot on December 07, 2012, 01:18:59 PM Alright, Salmon you seem to better explain things rather than throw bits of code at me. You, my friend, didn't say thanks to me for either post. If you want to learn to code, then expect to get lines of code in reply. It is up to you to study them. Quote from: foxidrive on December 07, 2012, 02:00:28 PM You, my friend, didn't say thanks to me for either post. I agree 100% with foxidrive. You can save one or more variable name/value pairs, separated by an equals sign, to one file (or create the file manually in an editor, or make a script generate them) and use FOR to retrieve them. c:\>echo animal=cat > datastore.txt c:\>echo colour=red >> datastore.txt c:\>echo country=Russia >> datastore.txt c:\>for /f "delims=" %A in (datastore.txt) do @set %A c:\>echo %animal% cat c:\>echo %colour% red c:\>echo %country% Russia This was done at the prompt; in the FOR line use double percent signs (e.g. %%A instead of %A) in a batch script. This is what datastore.txt contains animal=cat colour=red country=russia Handy tip: FOR skips lines starting with a semicolon. Actually the final line of datastore.txt is now country=Russia The name of Russia correctly starting with a capital R. (I edited the script but forgot to correct the earlier version I posted before) |
