Skip a specific iteration in a FOR loop

In a game I am programming with Batch, a specific function is used to draw the map with a preset tileset. It's fairly complicated and takes more than a few seconds to draw the entire full color map.

I am trying to put an icon in for the player. Rather than changing the map data, I would like to implement it entirely within the graphics subroutine.

Right now, the icon displays, but it pushes the entire line of graphics back one space. I would like to make it skip the tile that the player is on top of, but the only way to do this seems to be to do something similar to ye olde NEXT command in BASIC. I am not aware of a Batch equivalent to this, so I have come here for help. I need to skip a specific iteration of the FOR loop after the player tile is drawn.

This won't make much sense without a considerable amount of context, but here's the subroutine as it stands:

:D
REM Draw tiles
IF /I %OSV% LSS 3 (
FOR /L %%G IN (0,1,31) DO (
REM Old tileset
IF "%2" == "1" IF "%%G" == "%X%" CALL :C 0C "i" & REM skip the rest
IF "!M%MAP%%1:~%%G,1!" == "0" CALL :C 00 " "
IF "!M%MAP%%1:~%%G,1!" == "1" CALL :C 2A "w"
IF "!M%MAP%%1:~%%G,1!" == "2" CALL :C 87 "S"
IF "!M%MAP%%1:~%%G,1!" == "3" CALL :C 6E "W"
IF "!M%MAP%%1:~%%G,1!" == "4" CALL :C 0A "T"
IF "!M%MAP%%1:~%%G,1!" == "5" CALL :C 0A "n"
IF "!M%MAP%%1:~%%G,1!" == "6" CALL :C 6E "H"
IF "!M%MAP%%1:~%%G,1!" == "7" CALL :C 91 "m"
IF "!M%MAP%%1:~%%G,1!" == "8" CALL :C 19 "m"
IF "!M%MAP%%1:~%%G,1!" == "9" CALL :C B3 "M"
IF "!M%MAP%%1:~%%G,1!" == "A" CALL :C 4C "m"
IF "!M%MAP%%1:~%%G,1!" == "B" CALL :C C4 "M"
IF "!M%MAP%%1:~%%G,1!" == "C" CALL :C 6E "O"
IF "!M%MAP%%1:~%%G,1!" == "D" CALL :C 6E "W"
IF "!M%MAP%%1:~%%G,1!" == "E" CALL :C 78 "W"
IF "!M%MAP%%1:~%%G,1!" == "F" CALL :C 0D "X"
IF "!M%MAP%%1:~%%G,1!" == "G" CALL :C 6E "E"
IF "!M%MAP%%1:~%%G,1!" == "H" CALL :C 48 "E"
IF "!M%MAP%%1:~%%G,1!" == "I" CALL :C 68 "n"
IF "!M%MAP%%1:~%%G,1!" == "J" CALL :C 6E "m"
IF "!M%MAP%%1:~%%G,1!" == "K" CALL :C E6 "W"
IF "!M%MAP%%1:~%%G,1!" == "L" CALL :C 6A "T"
IF "!M%MAP%%1:~%%G,1!" == "M" CALL :C 2A "w"
IF "!M%MAP%%1:~%%G,1!" == "N" CALL :C 87 "S"
IF "!M%MAP%%1:~%%G,1!" == "O" CALL :C 0D "i"
IF "!M%MAP%%1:~%%G,1!" == "P" CALL :C 6A "Y"
IF "!M%MAP%%1:~%%G,1!" == "Q" CALL :C BF "C"
)
)
GOTO :EOF


Please note I removed the advanced ("Fancy") tileset because it added more complexity and didn't show up correctly here.

After the character is drawn (the sixth line), I need to skip the rest of the sequence to prevent it from drawing the tile that the player is standing on top of.

The variables passed to the function are:

There are no outputs except to the terminal via the C function, which simply draws a colored character.

Any ideas would be great.

EDIT: Here is some example outputs without the player icon. The red nembers indicate the player's position. I would like to replace the tile at this position with the player's icon.

You didn't create an MCVE and your code doesn't make sense since if it stops after the 6^th line then the rest is just useless and there's no need to loop 32 times. Thus this is just an example

To prevent the block from running when a condition is true, just invert the condition

FOR /L %%G IN (0,1,31) DO (
rem Things that will done every time
IF NOT "%%G" == "6" (do something) else (
rem Things that will be done when %%G != 6
rem i.e. if %%G != 6 next
)
)


In this case if you want to skip the remaining commands when the conditions on the first line is true then

FOR /L %%G IN (0,1,31) DO (
IF "%2" == "1" IF "%%G" == "%X%" (CALL :C 0C "i") ELSE (
IF "!M%MAP%%1:~%%G,1!" == "0" CALL :C 00 " "
IF "!M%MAP%%1:~%%G,1!" == "1" CALL :C 2A "w"
IF "!M%MAP%%1:~%%G,1!" == "2" CALL :C 87 "S"
IF ...
)
)


Again the for loop is not necessary, since every loop you only jump into one case. The first line looks like it's checking if that's the player, so just split it into a separate function

IF /I %OSV% LSS 3 (
IF "!M%MAP%%1:~0,1!" == "0" (call :checkplayer %2 %%G %X% || CALL :C 00 " ")
IF "!M%MAP%%1:~1,1!" == "1" (call :checkplayer %2 %%G %X% || CALL :C 2A "w")
IF "!M%MAP%%1:~2,1!" == "2" (call :checkplayer %2 %%G %X% || CALL :C 87 "S")
...
)

:checkplayer
IF "%1" == "1" IF "%2" == "%3" (
CALL :C 0C "i"
exit /b 0
) ELSE (
exit /b 1
)
