Problem copying BMP file from one folder to another

Problem copying BMP file from one folder to another - 09/04/08 00:26

In this current project I have it set up so F11 takes a screen shot. My SAVEDIR is set to "data" and all screen shots are automatically saved in there as that's how 3DGS works. Since I have other things in the data folder (settings files, etc.) that are also saved there by the engine, I want to have the screen shots in their own folder, like "screenshots".

I am using the following code. Basically it takes a sequentially numbered screen shot, puts it in the data folder, then copies it into the screenshots folder (I haven't written the part to delete the original yet; that's coming).

It all works great except that the resulting file in the screenshots folder is only 0k in file size. Something is going wrong somewhere and I can't seem to figure out where.

Can anyone spot the problem?

Thanks!

Code:

var shotfilehandle;
var shotfilehandle1;
var theShotNum;

STRING theScreenShot = "#64";
STRING theNewShot = "#64";

STRING theShotNumString ;

action take_shot(){
	
	str_cpy(theScreenShot, "image_");  
	str_cpy(theNewShot, "screenshots\\"); 

	shotfilehandle1 = file_open_read("shots.num");
	theShotNum = file_var_read(shotfilehandle1);
	file_close(shotfilehandle1);

	theShotNum += 1;

	wait(1);
	snd_play(camera_click,100,0);

	wait(1);        

	str_for_num(theShotNumString,theShotNum);
	str_cat(theScreenShot, theShotNumString);
	str_cat(theScreenShot, ".bmp");

	str_cat(theNewShot, theScreenShot);

	file_for_screen("image_.bmp",theShotNum);  // saves a screenshot with a sequential suffix
	
	shotfilehandle = file_open_write("shots.num");
	file_var_write (shotfilehandle, theShotNum);
	file_close(shotfilehandle);   

	file_cpy (theNewShot, theScreenShot);
 
	str_cpy(theScreenShot, "image_");  
	str_cpy(theNewShot, "screenshots\\"); 

	wait(1);
}

Perhaps, this will be of some help.
(Probably not.)
C-Script file copy;
tested
Use \\ as path separator and workdir (ifdef DEVELOP) and exedir (ifelse) respectively.

Code:

/************************************
	filef_copy
*************************************/
var file_nFrom = 0;
var file_nTo = 0;
var file_nByte;

function filef_copy(_sFrom, _sTo) {
	var ret1; ret1 = 0;
	file_nByte = 0;
	file_nFrom = 0;
	file_nTo = 0;
	if (_sFrom == 0) {
		return(0); 
	}
	if (_sTo == 0) {
		return(0);
	}

	file_nFrom = file_open_read(_sFrom);
	if (file_nFrom == 0) {
		error("!error filef_copy: file from not found!");
		return(0);
	}
	
	file_nTo = file_open_write(_sTo);
	if (file_nTo == 0) {
		error("!error filef_copy: file to not found!");
		return(0);
	}
	while(1) {
		file_nByte = file_asc_read(file_nFrom);
		if (file_nByte != -1) { 
			file_asc_write(file_nTo, file_nByte);
			ret1 += 1; 
		} else {
			break;
		}
	}
	file_close(file_nFrom);
	file_close(file_nTo);
	return(ret1);
}

Thanks for trying. The code still didn't work for me but I figured out a solution to my problem anyway.

The manual implies that the screen shots can only be saved into the SAVEDIR folder, but I found out that you can add a path with no problem. So instead of copying the file out of "data" and into "screenshots" I just save it to "screenshots" to begin with.

The manual also says that file_cpy only works within the SAVEDIR folder but it turns out you can use paths with that one also.

Anyway, thanks again. Problem solved.

It's good that the problem is solved.

Indeed, file_cpy seems to copy correctly from and to paths other than the save_dir.
