With the statistic() command.

@Brendy boy: Yes that is definitely one way to achieve but can we get the value using dark basic pro code ? Or more specifically on a per object / mesh basis ?

You could take a look here:
http://forum.thegamecreators.com/?m=forum_view&t=195284&b=1
Helpful a conversation about determining the memory usage of a cube.

I don't think there is any real way to do it inside DBP.

@Juggernaut

I don't know if these commands exist in DBPro or not but they are in DBC:

SYSTEM DMEM AVAILABLE() will return the total video memory available
SYSTEM SMEM AVAILABLE() will return the total system memory available
SYSTEM TMEM AVAILABLE() will return the overall system memory available

So you could take a memory profile before creating/loading your objects then take a profile after and find the difference.

Enjoy your day.

yes, using this commands:
Quote: "
return integer = GET INSTALLED MEMORY( Type )
return integer = GET MEMORY AVAILABLE( Type )
return integer = GET MEMORY PERCENT USED( )
return integer = GET MEMORY PERCENT FREE( )
"

which are part of this plugin

Quote: " Or more specifically on a per object / mesh basis ?"

no

You can't say that, you just don't know if it's possible. Of course there's a way to determine the RAM consumption...

@zeroSlave: Thank you for pointing out the thread. Yes it is very much related to this current thread. It will take me some time to get to the bottom of that discussion.

@Latch: This is as far as I could get with your hint -



But the result does not exactly tally with the task manager readings. Maybe I am missing something here .....

@Brendy boy: The commands mentioned by you can also be used in the similar fashion as mentioned in the above code - I guess

Thanks,

The code above would surely only find the memory used by the new sphere object you've created and not what is used by the application as a whole so it probably wouldn't tie up with what is in task manager. Sorry if I'm misunderstanding.

@Andrew_Neale: Thank you Andrew for pointing out the fact regarding the task manager anomaly. By the way .... you are from the most historically famous geographical region of world war II ! Glad to know.... you are among us .....

not sure if this has been mentioned before but you could do a check for memory available and then create the cube then check for memory again?

surely it would give somewhat of an estimate I think I did this a while back...

so

Quote: "
A=check free memory
create cube
B=check free memory
subtract A from B
C=result
"


something like that...

Memory usage will be volatile. It can change at any time. The commands are guides and not absolutes but can give you a pretty good idea of memory usage.

Also, the memory use can be different if you run in full screen exclusive mode where most of your system resources will be used for your game. In windowed mode, you'll be sharing a lot more stuff with Windows OS so the values may not match up as you expect.

Here's the commands usage example:



Also if you have over 2 gigs of ram, the value might show as negative because of the size of a 32 bit integer. You may be able to cast the variable as a double.

Enjoy your day.
