i think the source is self-explanatory...

there seems to be a small problem in unpack.c. the loop seems to run once too often. i get one printf() too much. maybe someone can figure out how to fix this?

Thanks!

Could you make an example for encryption? When I hardcode the password into my Lite-C program and compile it to EXE, the password is protected, I guess?

Cheers, Christian.

no, all strings in an exe can be seen in a hex editor, so your plain text password wouldn't be that safe. but you could encrypt the password too.

encryption could be added quite easily but i don't think it's really necessary. it's a custom format anyway which can't simply be opened with winzip. you could further customize it so that it is more difficult to figure out for other gamestudio users. in the end all encryption is quite useless since with all filepackers your data will land in ram unencrypted anyway and there are plenty of tools for accessing it there.

Ok... I think its fine in its current state. Thanks

did anyone have a look at why the loop runs once too often in unpack.c? i guess i don't use feof() correctly? i could solve it differently but using feof() would be more elegant if it worked.

if i remember right, feof is executed after a failed fread instruction because of an feof error.

==>

while(!feof(fp))
{
long length;
fread(&length, sizeof(long), 1, fp);
if(feof(fp)) { break; }

no very elegant, but.. it should work

thanks! it was the first time that i used feof().

i have solved it like that now:

long length;
while(fread(&length, sizeof(long), 1, fp)) // while not eof
{

please download it again if you have the old version!

just for fun i have added encryption support.

the key isn't text but 4 numbers so it shouldn't be that easy to find it in the exe with a hex editor. but since other gamestudio users who can experiment with the filepacker source could do comparisons of the surrounding bytes or something like that you maybe should move the key around a bit (into a different function of your script or so).

(keep my second post in this thread in mind.)



<edit>...of course encryption is useless for the free lite-c since you can't really hide the source code and the key there. so i would remove the encryption part of the script when using it with the free lite-c.</edit>

Thanks!

pack.c crashes at first addfile, using 7.07 ???

edit: nvm i forgot to copy zlib dll.
