DUKHELP3.zip Make edit/play batch files so level builders can easily make backups 'n load maps into MakeMap 'n RR or RA
with this help.zip file for DOS. Batch files are made from source files loaded into TTYPE.COM 'n every place the source file has %1 in it, ttype.com input#1 is substuted 'n saved to outfile.ext. TType.com takes 1-9 inputs, 256 characters total. This way very complicated batch files can easily be made for MakeMap 'n RR or RA even if you've renamed the files or if you want a path\command. . . . . . . . . . . . . . . . . .
The batch files load the last map you've made. Saving map backups is easy with numerically incremented basenames 'n the batch files look for the largest number to load, which is the last map you've made. After 20 backups are made, move em to a backup directory, 'n start again.
By the time I'm done makin a map I have over 200 backup files. And they have bailed me out on many occasions. . . . . . . . . . . . .
Any time a map gets corrupted, I can start again with a former backup file 'n not much of my time is wasted. (updated 5-10-2002)
