Save/load selected cubes

This is idea in editing.
Like copy/paste, but you can save selection on disk and load it later or use in other maps. For example, you create arch/sphere/house and want to save it on disk to use later or use on other map.

These cube "presets" will keep much time when you using geometry of the same type (arches and ladders for example). You could "save" house/ladder/shere from one map and use it in your own map. Very convenient.

Is there any complete solutions?

I think it's possible to create preset library of houses, laggers, spheres, circles, arches and so on like mapmodels, but based on octree geometry.

/loadpreset sphere_4.oct -> put in cursor sphere of radius 4 (just suggestion).

The only solution right now is to save it in a separate map. (Copy-paste works across maps.)

If you want REAL prefabs, feel free to mod the source to make it possible. (I suggest serializing the cubes you copy into a format you can paste into a CFG.)

Yes, I think it is easy, I'm C programmer too, but I don't know cube 2 engine well, 2 megabytes of source is hard to study:). I need to analyze sources before I can modify it.

Easier than I thought. I did it!

Here the code I just added in octedit.cpp:

editinfo *preset = NULL;
void savepreset(char *name)
{
vector<uchar> buf;
mpcopy(preset, sel, false);
if(!packeditinfo(preset, buf)) {
conoutf(CON_WARN, "could not get selection"); return;
}
stream *f = openfile(name, "wb");
if(!f) { conoutf(CON_WARN, "could not write preset to %s", name); return; }
f->write(buf.getbuf(), buf.length());
delete f;
conoutf("wrote preset file %s", name);
return;
}
void loadpreset(char *name)
{
int outlen = 0;
uchar *outbuf = (uchar*)loadfile(name, &outlen);
ucharbuf buf(outbuf, outlen);
unpackeditinfo(preset, buf);
mppaste(preset, sel, false);
delete[] outbuf;
return;
}
COMMAND(savepreset, "s");
COMMAND(loadpreset, "s");


Files may be also gzipped.
Now we can collect library of mapmodels in native octree format:)

Nice.

Maybe you also want to put

if (noedit(false, true)) return;

at the beginning of each function.

if (noedit(false, true)) return;

What does it mean? false, true... maybe:)

The function noedit test if you are in edit mode.

The first value decides if the selection can be outside of your view.
Set it to false so you don\'t edit your selection by accident if you forgot about it, e.g. if you want to edit something later without selecting it explicit and the old selection is still active.

The second value just enables error messages.

The return value gives you the \"its ok to edit\" or \"no no\".

I hope to see it in the next release.
Next step - adding presets in menu like mapmodels.

May I also suggest a variable to define where these prefabs are stored, so we don't have them cluttering up packages/base? ;)

Also, I'm curious to know why you're delete-ing things that haven't been new'd.

I think "packades/presets" will be enough.
packades/presets/ladders
packades/presets/arches
packades/presets/buildings
packades/presets/etc...

I would be very grateful if someone will make a set of primitives such as circles, cylinders, spheres, arches.

What are you talking about?

It was a misprint :D

Unless I'm missing something really obvious.

As for your primitives:

They'd just need to be broken up. :)

Taken from original cube source. I think that's right.

Done:

showpresetsshot = [ guibar; guiimage (concatword "packages/presets/" (if (> $numargs 0) [result $arg1] [result (at $guirollovername 0)]) ".jpg") $guirolloveraction 4 1 "data/cube.png"]

newgui presets [
guilist [
guilist [
loopfiles f packages/presets pgz [
guibutton $f (concat loadpreset $f) "cube"
]
]

]

0.0! Very interresting! I really hope it makes the next release, so not only people who map and also program take profit out of it, but also average knowledged mappers.

My code still not working as I want. When I try to save/load file only by name (house.pgz for example) - all right. When I try to load it from packades/presets - "could not load preset".
I tried to use "findfile" function - useless. Wheni try to load file from any other folder (except "loadpreset house") - fail.

How to load files from packade folder correctly?
The source code is poorly documented:(

And is there any way to post sources (like patches on sourceforge)? Or devs not take someone else's code?

I think you should load presets/blah, not packages/presets/blah.

opengzfile("presets/sphere_1.pgz"), "rb");//not working

opengzfile("sphere_1.pgz"), "rb");//working, because i have sphere_1.pgz in ~/.sauerbraten/packades directory

I think engine doesn't load file from "packades" in game, but loads files from "packades" in home directory.

You'll have to do something like this:
defformatstring(tmppath)("packages/%s.pgz", ppath);
path(tmppath);
opengzfile(tmppath, "rb");

That should work.
