Ok, I don't know where I posted this.
but, this program reads a file in that looks like this:
badtileid,goodtileid
badtiledi,goodtileid
it doesn't have any error checking, so I would add spaces, etc. The tileids are in decimal.
Now, the progam is executed like this:
tileswap tilefile mapmulfile
Where tilefile is the file described above, and the mapmulfile is the map#.mul you want to modify. Bot file names need to have their full location specified. You start the program from the command line!!!!
Make a BACKUP before you try this. UNTESTED.
Code:
#include <fstream>
#include <string>
#include <iostream>
#include <cstdlib>
#include <map>

std::size_t index=input.find(",");
if (index != std::string::npos)
{
std::string first = input.substr(0,index);
std::string second=input.substr(index+1);
key=std::atoi(first.c_str());
value=std::atoi(second.c_str());
rvalue=true;
}
return rvalue;
}
int main (int argc, char *argv[])

std::map<unsigned short,unsigned short> swaptable;
