[HELP]Can I make a mod ?

I don't know Turbo C++. You could even edit sources via notepad, QTCreator, VIM or whatever if you like. If you would compile there are fewer possibilities (on windows cl.exe from MSVC or mingw on linux standard gcc/g++). Here you find links to the current source and a how-to for compiling:

I think nobody can answer you if you would be able to create mods. If you know already C++ it's better then starting from scratch. Hint: If you would start coding on a mod search for the entities folder search for character.cpp (lots of stuff could be done there) and so on...

Edit client-sided source files and compile the whole with the bam command bam release like it's said in the documentation which you definitely should read closely.

I know a bit about C + +.Also I know a bit about lite-c or c-script.
I have the bam-0.4.0 but,It needs to install visual c++.I can't download visual c++ because my windows isn't update

Mingw works with new versions of source (I've already used it at my alien-mod). But you need to provide some mingw libs afterwards as well. This should be mostly ok but you have to know it coz with cl.exe from some VC-Express you don't need them. If you don't use MingGW then I would recommend VC-2008 Express (the *.iso version). I think it's the latest version where you don't need to register with some account: http://www.microsoft.com/download/en/de … x?id=20682

You need VC only if you would compile an older version of TW then that which you would find on github. If you use the latest version from github (which I would recommend if you start modding) then you may even use MinGW as your compiler for BAM and TW (you would even need some 2.6 Python... I'm not sure if newer would work). You should be able to get MinGW from here: http://sourceforge.net/projects/mingw/f … -20111118/ ... after installation (I'm not sure if this would be done by the Inno-Installer) take a look at your environment-variables and make sure if the MinGW binaries are in your PATH. Then compile bam extract the TW source remove the config.bam if there is any and make a new one with bam -c all.
