that command is in all of the magic windows examples and it must be like the lock cli command (can't remember the word for that) because in darkedit it doesn'tcome up as a command but still runs any ideas?

That's funny, because it did not come up in the DBC help file, yet it didn't error when I ran a DBC program with it in it. Anyway, from the DBP help files (I assume DBC would be similar):
This command will flush all textures and other resources from active video memory.

You should use this command when you are dramatically changing the contents of your 3D scene such as changing game levels or entering a new environment. This technique will improve performance during the initial renders of a new scene.

I believe it was one of the "hidden" commands of DBC, meaning it is a command that wasn't fully developed and isn't really complete, so to speak.

It cleans out the video memory leak from importing lots of images but from having used it to cure my leak problem I think the impact is purely cosmetic. i.e. the value returned from video dsem() (sorry cant remember the exact command) may increase after using the command but in reality I'm not sure it has.

NaGaCreMo (which stands for National Game Creation Month) was established over in the Geek Culture forums last year. You take part in a resolution to complete a WORKING program (whether it be a game or application or even a screen saver) within the first 30 days of the new year. As far as I know, it will become an annual thing (its first year was this year (I think)). It was a lot of fun, really made me focus on programming and helped me gain a little more experience in programming. So if you're interested in it Caleb, start planning for next year.

Hmm, I just used this command in a new project of mine. It sort of did speed up the initial render, even when I was running Firefox (which isn't really recommended for testing/playing games. ).


In DarkEDIT it doesn't bold or turn red though, but I guess that's because it's an in-complete command (though it seems to work for me).

The "hidden" commands are incomplete, as mentioned above. That means they are not all secure to use, and could cause memory leaks... But what the hell?

Can someone make a list of them?

I remember 3 of them:

3ds2x

converts a 3ds file to an x file

break

will make that cli bar thingy pop up in mid program.

flush video memory

---

TheComet

Peachy, and the Chaos of the Gems

A list should be in the downloadable help.

hidden commands 1

hidden commands 2

And for good measure:

LOCK CLI - disables the command line interface on execution pause or termination

UNLOCK CLI - enables the command line interface

| (binary OR)


& (binary AND)


! (not the same as)


set static objects wireframe on

set static objects wireframe off

STATISTIC(1) - number of polygons being rendered



Enjoy your day.
