Take Screenshots

[Qbound]

Hi Werker's,

 

if you want to take screenshots you can use the SaveBuffer() function on the Backbuffer(), thats an easy way.

 

But what about the naming?

 

My Game NightFist is slowly growing and i want to document my progress with screenshots.

Therefore i took a few minutes to find an easy solution to create good names.

 

Here is my way

#include <time.h>
#include <string>

 

// Take Screenshot?
if( KeyHit( KEY_F12 ) )
{
//
// Create the name and save it (using the format 'NightFist_2009_12_06-13_59_42.jpg'
//

// Variablen init
time_t	mTime = time( NULL );												// Time
tm	*mDate = localtime( &mTime );											// DateTime Structure
char	cBuf[40];													// copy Buffer

// Now Create the TimeStamp for the file
sprintf( cBuf, "%4d_%2d_%2d-%2d_%2d_%2d", mDate->tm_year + 1900, mDate->tm_mon + 1, mDate->tm_mday, mDate->tm_hour, mDate->tm_min, mDate->tm_sec );

// Start with the Prefix
std::string strName = "NightFist_";

// Then the Timestamp
strName += cBuf;

// and the ending
strName += ".jpg";

// Save Buffer
SaveBuffer( BackBuffer(), (str)strName.c_str(), 85 );
}

 

have fun and let us see your screenshots

This looks very good!

 

I have an error though:

 

it says that 'string' is an undeclared identifier, which is weird because it's a data type.

Ah thanks for the tipp Aggror, there is the string include and the namespace missing.

 

i have updated the code. this should work.

It's probably because you haven't included using std namespace; before using the string data type, or you should use std::string in place of string. Either option will get you the same results, but the latter does not require using std namespace be defined first.

Who buffer save if i use a Framewerk.h?

SaveBuffer( buffer, (str)strName.c_str(), 99 );

I obtained only black images

You need to get ColorBuffer(buffer,0) of the buffer.

You need to get ColorBuffer(buffer,0) of the buffer.

 

I'm use:

SaveBuffer( CurrentBuffer(), (str)strName.c_str(), 99 );

[Canardia]

There is no command called CurrentBuffer(), I think you meant BackBuffer().

Then your command should be:

SaveBuffer( GetColorBuffer(BackBuffer(),0), (str)strName.c_str(), 99 );

Ok, Thanks!

I had something similar to this working in earlier version of LE, but now all I get is a black image.

 

Here is some code:

 

SaveBuffer(BackBuffer(),filename, 100);
strcpy(g_strScreenshot, filename);
g_bScreenshotMsg = true;
sprintf(temp, "Saved screenshot as: %s", g_strScreenshot);
AppLog(temp, 0);
done=true;

 

I am using Framewerk and LE 2.28, do I need to pass a buffer from Framewerk or is using BackBuffer still fine?
