Description: Tutorial explaining the usage of batch files in D2 modding.

Categories: Tutorials (1.1x) - Diablo Mod Setup


Back in the good old days of DOS, we had batch files that let us simplify

certain tasks such as renaming a large quantity of files.

A BATch file is just TEXT, so open it in notepad or in DOS with edit.com.

There is no history lesson here, batch files are a kind of programming, for

more information check out:


Batch File Help

The Ancient Art of DOS Batch Files





--- commands ---



@echo off ; turns off echoing to the screen so that you dont see the command 

being issued, only the result. 



echo Hello ; when used in conjunction with @echo off it puts the text onto 

the screen like this:

Hello



if @echo off is not present then you will see:



c:\echo Hello



Hello



cls ; clear screen



pause ; pauses the batch program and waits for user to hit a key



rename filename1 filename2 ; renames filename1 to filename2



copy filename1 filename2 ; makes a copy of filename1 called filename2



del filename1 ; deletes the file



You can also execute programs from a batch file, just put the name of the 

program in its own line like so:



mpq2k ; will run the program mqp2k.exe



--- how to make a patch so that you can release it for public use ---

--- make a file called patch.bat and put the following 'code' inside of it ---



--- cut below ---



@echo off

cls

echo This mod was made by name@email.address

echo With this mod Diablo 2 will drop all unique weapons when a monster 

is killed most of the time

pause



copy patch_d2.mpq patch_d2.old

mpq2k a patch_d2.mpq itemratio.txt data\global\excel\itemratio.txt

echo Patching complete!



--- stop cutting above ---





an explination of the code above:



@echo off ; turns off echoing

cls ; clears screen

echo This mod was made by name@email.address ; shows who made this

echo With this mod Diablo 2 will drop all unique weapons when a monster is 

killed most of the time ; tells what it does

pause ; waits for user to press a key, in this time they can close the 

program so that it doesnt do any patching



copy patch_d2.mpq patch_d2.old ; backs up the original patch

mpq2k a patch_d2.mpq itemratio.txt data\global\excel\itemratio.txt ; runs 

the program mpq2k and imports the new file into the mpq archive

echo Patching complete! ; tells user patch is done doing its work.



--- make a file called uninstall.bat ---

--- cut below ---



@echo off

echo this will restore your original patch file and delete any 'hacks' 

you have enabled.

del patch_d2.mpq

copy patch_d2.old patch_d2.mpq

del patch_d2.old



--- stop cutting above ---



Now when you want to release a mod all you have to do is release 2 

batch files, an installer, and an uninstaller. Also the files that 

you want to add to the users MPQ file. For my all uniques patch i 

would have to release the following files:



patch.bat

uninstal_all_unique.bat

itemratio.txt



The USER MUST HAVE MPQ2K and STAREDIT in the same directory as diablo 2, 

so if they do not have it, they can just download the Diablo 2 Mod Creation

Kit. Also the user must unzip the patch to their diablo 2 directory and 

run it from there.
