Batch movement

[batnoob]

I can't seem to figure out how to create movement like Snake.bat i think i got it a little bit but i cant figure out the rest. Here's what i got:

Code: Select all

:setup
@echo off
set lsp=    
set char=X
set rsp=    
set wall=#

:1
cls
for /l %%a In (1 1 11) do (<nul set /p "=%wall%")
echo.
for /l %%a In (1 1 4) do (echo %wall%%lsp% %rsp%%wall%)
echo %wall%%lsp%%char%%rsp%%wall%
for /l %%a In (1 1 4) do (echo %wall%%lsp% %rsp%%wall%)
for /l %%a In (1 1 11) do (<nul set /p "=%wall%")
echo.
choice /c ADS /m "S resets"
if %ERRORLEVEL% == 1 (CALL:Left) ELSE if %ERRORLEVEL% == 2 (CALL:Right) Else (goto :setup)
goto :1
pause
exit /b

:Left
set lsp=%lsp:~0,-1%
set rsp=%rsp:~0,+1%
GOTO:EOF

:Right
set rsp=%rsp:~0,-1%
set lsp=%lsp:~0,+1%
GOTO:EOF

Thank you, BatNoob

Are you trying to remove the tail like in snake.bat? If not then you can have a look at my lilgui.bat

Code: Select all

lilgui /a # /h 11 /w 11 /s 6-6 /pc X

no, i am just trying to move the 'X' without moving the entire wall

In that case my tool is perfect for you.

The variable string manipulation doesn't work, as it seems you have expected:
The expression "%lsp:~0,+1%" does not append a character at the end of lsp, instead it only prints one character starting with index 0.

So this might help you:

Code: Select all

:setup
@echo off
set lsp=    
set char=X
set rsp=    
set wall=#

:1
cls
echo "    " "    "
echo "%lsp%" "%rsp%"

for /l %%a In (1 1 11) do (<nul set /p "=%wall%")
echo.
for /l %%a In (1 1 4) do (echo %wall%%lsp% %rsp%%wall%)
echo %wall%%lsp%%char%%rsp%%wall%
for /l %%a In (1 1 4) do (echo %wall%%lsp% %rsp%%wall%)
for /l %%a In (1 1 11) do (<nul set /p "=%wall%")
echo.
choice /c ADS /m "S resets"
if %ERRORLEVEL% == 1 (CALL:Left) ELSE if %ERRORLEVEL% == 2 (CALL:Right) Else (goto :setup)
goto :1
pause
exit /b

:Left
if defined lsp (
   set "rsp=%lsp:~-1%%rsp%"
   set "lsp=%lsp:~0,-1%"
)
GOTO:EOF

:Right
if defined rsp (
   set "lsp=%rsp:~0,1%%lsp%"
   set "rsp=%rsp:~1%"
)
GOTO:EOF
