Interference22	Using FileWriteString and FileReadString to create save files is presenting me with a problem. Saving integers as strings and then val()ing them back to integers is fine, but my strings are getting junk characters added to the end of them. I tried to load the current map the player was in from my save file. The string should contain the word "test," which then has a "m-" stuffed at its star and a ".map" at its end in the mapload function to load "m-test.map." Instead, it crashes with this error: Is it reading the ASCII characters that mark the end of a string as well as the string? My VC doesn't seem out of the ordinary, its just a straight set of FileWriteString()s in the save game function and a load of FileReadString()s in the load function. The mode for FileOpen() is set correctly in both cases. Posted on 2004-04-23 22:46:58
vecna	quite likely. the file i/o functions havent been tested extensively since the first time they were written over a year ago for the original version of v3. I'll look into it this weekend. Posted on 2004-04-24 01:26:00
rpgking	There definitely is a problem with these 2 functions. I forgot to report this earlier, but I encountered the same thing when working on Balloon Ninjas, and had to make my own custom functions to do these... Posted on 2004-04-24 05:45:07
vecna	I am trying to debug this now, but am unable to duplicate any problem. Here's the code I'm using: void autoexec() { int f = FileOpen("caca.txt", FILE_WRITE); FileWriteString(f, "This is a test of your mom!"); FileClose(f); f = FileOpen("caca.txt", FILE_READ); string s = FileReadString(f); FileClose(f); Exit(s); } It works fine. Can anyone give me code that doesnt work? Posted on 2004-04-26 23:47:04
rpgking	void autoexec() { int f = FileOpen("caca.txt", FILE_WRITE); string s; FileWriteString(f, "rpgking"); FileWriteString(f, "100000"); FileWriteString(f, "vecna"); FileWriteString(f, "1111111111"); FileClose(f); f = FileOpen("caca.txt", FILE_READ); s = FileReadString(f); log(s); s = FileReadString(f); log(s); s = FileReadString(f); log(s); s = FileReadString(f); log(s); FileClose(f); Exit(""); } These are my logfile results: --------------------------------- rpgking 100000g vecna0g 1111111111‹ FileWriteString is supposed to write a string to a binary file right? And FileReadString reads the next string from that binary file? If so, then something's not working right with the functions. If not, there's something I'm missing here :P Posted on 2004-04-27 03:48:34 (last edited on 2004-04-27 04:01:44)
mcgrue	Zany. I get: rpgking 100000g vecna0g 1111111111a1" why the difference, I wonder... Posted on 2004-04-27 06:45:04
Rysen	What's really weird is that if I do vec's version and open caca.txt, everything looks fine but when I do rpgking's, I get Japanese kanji. o_O In the log file though, I get the same result as grue. Posted on 2004-04-27 11:05:50
el_desconocido	I think the internal string buffer is not being cleared for some reason.~~The 0g after vecna is left from lines 1 and 2.~~ Using two different strings also lets artifacts through. Caca.txt does have binary seperators, don't know if that's the intention. Or maybe that's chance because: This: FileWriteString(f, "-rpgkingisagog"); FileWriteString(f, "1"); logged this: -rpgkingisagog? 1`[ð]H Posted on 2004-04-27 15:11:44
rpgking	Grue's log file is probably correct. I may have copied the last few weird characters wrong. Posted on 2004-04-27 16:46:19
vecna	Yeah, caca.txt was a misleading name. It's not really a text file, there are binary values output by FileWriteString(). Should be fixed this weekend. Posted on 2004-04-27 18:06:55
mcgrue	Just in case there was any confusion, I was reporting my v3.log's contents after the: s = FileReadString(f); log(s); s = FileReadString(f); log(s); s = FileReadString(f); log(s); s = FileReadString(f); log(s); section of the above code. Posted on 2004-04-27 21:08:27
el_desconocido	I knew what you meant but was confused myself. Entire Autoexec() void Autoexec() { int f = FileOpen("caca.txt", FILE_WRITE); string s; string t; FileWriteString(f, "-rpgkingisagog"); FileWriteString(f, "1"); FileWriteString(f, "vecna"); FileWriteString(f, "1111111111"); FileClose(f); f = FileOpen("caca.txt", FILE_READ); s = FileReadString(f); log(s); t = FileReadString(f); log(t); FileClose(f); Map("Xtreme.map"); } Entire v3.log: VC System Compilation stats: 34 ints (285 expanded), 3 strings (51 expanded), 19 functions, 803 total lines compiled Xtreme.map, (551 lines) number of funcs is 56 -rpgkingisagog? 1`[ð]H (eof) And caca.txt looks correct.

vecna	fixed in the next build - you can get a quickfix exe here Posted on 2004-04-30 03:00:41
