How do I get Batch to recognise variable is equal to '#' instead of 'a'

792 Views Asked by At

I want to create a batch file rogue like, however I need to fix a slight problem. When the character walks into a wall ( # ) I want the character to go back a step, and that works, however I cannot get the batch script to recognise if the character has walked into a wall!

@echo off
set drive=%~dp0%
:start
echo %~dp0%
echo Set name
set /p file=">"
if not exist "%drive%Locations\%file%.bat" goto mdfile
set x=12
set y=15
goto level
:level
set loc=x%x%y%y%
set x%x%y%y%=a
call %drive%Locations\%file%.bat
if '%loc%'=='a' goto start
if '%loc%'=='0' echo Entered shop && pause && goto %dire%
if '%loc%'=='~' echo You are drowning && pause && goto boucle
goto boucle

:mdfile
call %~dp0%Locations\make.bat
set x=12
set y=15
goto level


:boucle
cls  
echo.
call :map
echo.
echo %loc%
if '%%!x%x%y%y%!%%' == !#! (echo Equal) else (echo Not Equal)

echo q w e a s d ///// %let%
echo.
set loc=x%x%x%y%
choice /c qweasd /n >nul
if %errorlevel%==1 goto :savenum
if %errorlevel%==2 goto :up
if %errorlevel%==3 goto :savenuma
if %errorlevel%==4 goto :left
if %errorlevel%==5 goto :down
if %errorlevel%==6 goto :right
goto boucle

Essentially, the call :level command calls the set x1y1=. all the way through to set x24y30=. . This is the way the map is refreshed. after that, there is set x%x%y%y%=a to show the avatar. The walls are set after that line. I want the batch script to recognise it has walked into a wall because the avatar is not set to a, but rather the avatar is # instead. then it would goto :dire and reset where the avatar is. any help?

Here is the "make.bat" file mentioned. to test, make sure it is in the same directory as this batch file, in a subdirectory folder called "Locations"

 echo set x%%x%%y%%y%%=a)>%drive%Locations\%file%.bat

A.S.C

(Edit Stephan): this is make.bat that I created last week for testing (creates a random map) - maybe you find it useful:

@echo off 
<nul set /p "=building random map "
for /l %%x in (24,-1,1) do (
  <nul set /p "=."
  for /l %%y in (1,1,30) do (
    set "x%%xy%%y=."
    call :setvar %%x %%y 20 "#"
    call :setvar %%x %%y 10 "~"
  )
)
set "x5y5=@"
set "c0c0=#"
goto :eof
:setvar x y threshhold char
if %random:~-2% lss %3 set "x%1y%2=%~4"

I suggest this code which I could not test as posted code is not a minimal, reproducible example.

rem Prompt the user again on no file name entered at all.
if not defined file goto PromptName
rem Remove all double quotes from user input string.
set "file=%file:"=%"
rem Prompt the user again on just double quotes entered by the user.
if not defined file goto PromptName
rem Contains the entered string a character not valid in a file name.
set "ValidName=?"
for /F "eol=| delims=*/:<>?\|   " %%I in ("%file%") do set "ValidName=%%I"
if not "%ValidName%" == "%file%" goto PromptName

ATTENTION: The delimiters are */:<>?\| and a TAB and not three spaces as displayed and copied by the browsers.

The command lines starting with rem can be removed as they explain only the checks applied on the string entered by the user of the batch file.

The most important fix is the replacement of

if '%%!x%x%y%y%!%%' == !#! (echo Equal) else (echo Not Equal)

by

setlocal EnableDelayedExpansion
set "Char=!x%x%y%y%!"
endlocal & if "%Char%" == "#" (echo Equal) else (echo Not Equal)

The improved code first defines a new environment with making a copy of current list of environment variables used in the next two command lines with delayed expansion explicitly enabled while the state of command extensions is kept as is. The command SETLOCAL pushes on stack the current states of command extensions (enabled), delayed expansion (disabled) and current working directory.

The second command line builds dynamically the name of an environment variable during execution. The value of this environment variable is referenced with delayed expansion and assigned to environment variable Char.

The Windows command processor replaces on third command line %Char% by the value assigned to this environment variable in current environment variables list. Then the command ENDLOCAL is executed which deletes the environment variables list created before by SETLOCAL with the environment variable Char, restores the previous environment variables list, pops from stack the state of command extensions and sets the state (still enabled), pops from stack the state of delayed expansion and sets the state (disabled again) and pops from stack the current directory and sets this directory again as current directory which does not change anything here.

Next is executed the command IF which makes the string comparison whereby the left string does not contain any more %Char%, but instead the character determined before in previous environment with enabled delayed expansion.

The other improvements are:

  1. The execution environment required for this batch file is defined completely at top with the first two command lines which is command echo mode turned off, command extensions enabled and delayed expansion disabled. So the batch file processing does no longer depend on environment settings defined outside of the batch file.

  2. The full path of the batch file is assigned to an environment variable BatchPath using correct %~dp0 with % just at beginning of the argument reference and no one at the end. %~dp0 references the drive and path of argument 0 which is currently processed the batch file. The syntax for referencing argument string without or with a modifier is explained by help output on running call /? in a command prompt window. The batch file path always ends with a backslash. Therefore the concatenation of %~dp0 with a file/folder name or wildcard pattern should be done always without an additional backslash.

  3. On all command lines (re)defining an environment variable the entire argument string of command SET is enclosed in double quotes. The reason is explained in detail by my answer on Why is no string output with 'echo %var%' after using 'set var = text' on command line?

  4. The recommended syntax for an arithmetic expression is used on all command lines with command SET and option /A as explained by help output on running set /? in a command prompt window. In this case there are (usually) no double quotes needed as trailing spaces/tabs are ignored on evaluation of an arithmetic expression.

  5. The directory of the batch file is output without surround double quotes using delayed expansion to work correct even on batch file path containing one or more &.

  6. It is good practice to enclose argument strings in double quotes to make sure that a space and the characters &()[]{}^=;!'+,`~<>| are interpreted literally my the Windows command processor on parsing a command line. This is especially important for the two strings to compare with an IF and operator ==, especially if one of the two strings is an environment variable reference which can be replaced by nothing on environment variable not defined at all. A string comparison like if %variable% == string could be after processing if == string which is a serious syntax error as string is not a valid operator resulting in an immediate exit of batch file processing by cmd.exe which is never funny for a user using a batch file.

  7. The command IF compares strings always with the surrounding ". Therefore both strings must be enclosed in double quotes on comparing a variable string not containing a double quote with a fixed string. See also my answer on Symbol equivalent to NEQ, LSS, GTR, etc. in Windows batch files for details on how exactly a string comparison is done by IF. The character ' has no special meaning for the Windows command processor cmd.exe in comparison to Linux shell interpreters with the exception of enclosing a set of a for /F loop in '. For that reason only " should be used around two strings to compare and not other characters.

Stephan suggested a more effective way to show the map:

:map
setlocal EnableDelayedExpansion
%xay30%%xay30%%xay30%%xay30%%xay30%%xay30%%xay30%
for /L %%y in (1,1,32) do <nul set /P "=%c0c0%"
echo/
for /L %%x in (24,-1,1) do (
    <nul set /P "=%c0c0%"
    for /L %%y in (1,1,30) do (
        <nul set /p "=!x%%xy%%y!"
    )
    echo %c0c0%
)
for /L %%y in (1,1,32) do <nul set /P "=%c0c0%"
endlocal
goto :EOF
