Awesome!
Once the object table based placement goes live, you would be able to migrate your objects out of the doors table with a couple of SQL commands if you wanted.
Code:
INSERT INTO object (zoneid, xpos, ypos, zpos, heading, objectname, `type`, unknown08, unknown10, unknown20)
SELECT zoneidnumber, pos_x, pos_y, pos_z, heading, `name`, 0, 1 - ((opentype - 9) / 22), size, incline
FROM doors
INNER JOIN zone on zone.short_name = doors.zone
WHERE doors.opentype IN (9, 31);
Then when you're confident they're all now in objects correctly...
Code:
DELETE FROM doors WHERE opentype IN (9, 31);

Oh, you're working on that? I was working on that, too. How far along have you gotten? Should I just send you what I've been working on? I was implementing it via something like:
Code:
#object List All|(radius)
#object Add TypeNum Model [ObjectID]
#object Edit (ObjectID) (PropertyName) (NewValue)
(Properties: itemid, charges, model, type, icon, unknown08/10/20/24/60/64/68/72/76/84)
#object Move (ObjectID) ToMe|(x y z [h])
#object Rotate (ObjectID) (Heading)
#object Save (ObjectID)
#object Copy All|(ObjectID) (InstanceVersion)
#object Delete (ObjectID)

Oh sweet lol. I was just making something very basic and wasn't very far along just yet. I figured it could always be expanded on later, but wanted to get something working to start off with. Yours is much more in-depth than what I was doing, so I'll just leave it up to you 
The only thing I would add to what you have so far would be a way to despawn them. We should be able to use the ClickObject packet to handle that part. That isn't really too important though, and can always be added in later. Unless your delete option already does that. I like the move option you have. It sounds like a good idea and not hard to do. |

Per my testing, Delete does do a realtime despawn of the object, as Add does a realtime spawn. This allows object changes to be reflected in realtime by sending a despawn packet and respawn packet after each change. Using "#object delete" instead of attempting to trap ClickObject packets for placeables will prevent having the server do unnecessary processing with every click from every user on every object in the game.
The only caveat is that Doors do not have a Despawn opcode that I could find. They appear to be super-static by design. Unless we just haven't found the Opcode yet (since it's not likely to be found with packet collection from Live servers), I assume at this point that the client expects them to be sent once upon zone-in and never change. This also means that there will not be a Despawn packet for static objects.
The best way I can figure as to how to handle this issue is to spawn static objects and doors as tradeskill objects at first, allowing the user to make any model, location, and rotation changes they want to it, then change them into full-on static door objects when the "#object save" command is used to commit them to the database.
I could also look into utilizing an #object command to temporarily change an already-committed door or static object into a changeable tradeskill object upon the next zone-in, allowing the user to make any changes in-game and then re-commit with "#object save".
Should be entirely doable.

Note that I moved these posts from the SoF Development thread to here, since this is a better place to discuss it.
That sounds great, Shendare. Using temporary objects (from object packets) for placement and testing and then doors for actually saving them is exactly what I was thinking. I think that is probably the best option and should work out great and should be fairly seamless. I don't think people realize yet just how useful this command will be. It is good for adding custom stuff to zones, but it is also extremely good for adding in doors and such to newer zones that are currently completely empty. Until the packet collectors are working again, there is no easy way to do that, so this command will help a lot. The only way to do it better would be to manually pull the data from the Live packets and put them into the table. That is what I did for Crescent Reach, but not all zones are quite so accessible to collect from.

Shendare, how did you know that the tent you used is a global object (normaly its only found in Dranik)?
Is it because its located in live_event_objects.eqg?
does all other thing in live_event_objects.eqg are global?
Are there any other files?
are there any global doors? I am desperately trying to get a door into Guk Ldon

The particular tent I used isn't global. I had to add an entry in felwithea_assets.txt to pull in the models from live_event_objects.eqg.
To know what models are available globally, make a list of the files referenced in your EQClient\Resources\GlobalLoad.txt file.
Then check those files in the Model Inventory I linked to earlier, and any model names in that file's entry will be available globally.
http://www.jondjackson.net/eq/emu/fi...lInventory.zip
You can search the above inventory file for non-global objects available in your particular zone by searching for ZoneNick_obj.s3d or ZoneNick.eqg. The available model names will all be listed there. For guka, for example, I see a model called GUKDOOR700 that looks promising, as well as GUKMETGATE700 and GUKMETGATE701.
I have not found any global door objects via a quick skim of the global model files. However, you can easily add objects from other zones using the ZoneNick_assets.txt feature. Note that this is a client change that has to be done on each client that's going to be playing on your server.

Good progress in this project. I'm probably 80% done coding up the #object command. Hopefully by Tuesday or Wednesday night it'll be 100% functional and I'll post the code for it here.
I've now mostly got objects listing with List, spawning with Add, moving with Move, rotating with Rotate, saving with Save, and deleting with Delete. Only Edit and Copy really remain, then a bit of debugging, and I'll post the code for Trev to try out before submission to the SVN. This one will include a pretty hefty new code block in command.cpp, but it should be easy to copy/paste.
It will continue to use the objects table as-is for static objects (type 0) as well as ground spawns (type 1) and tradeskill objects (type 2+). No database structure changes required.
There will be #door commands similar to those for #object that I listed earlier, and they will work pretty much the same. Once I finish up #object, it'll probably be mostly a copy/paste to get #door working properly. Of course there will be no database structure changes for the doors table, either.

Wheeeeeeeew, this has been an educational endeavour! LOL.
Alright, I've gotten the #object command 110% functional. I've tested every part of its functionality, but it could most definitely stand to undergo additional testing from more users.
Note: Nothing in the commands is case sensitive.
First the breakdown on the new commands:
----------------
1. #object List - Lists all objects in the zone or within Radius units of you
Usage: #object List All|(Radius)
Examples:
- #object List All
- #object List 500
----------------
2. #object Add - Spawns a new object at your present location
Usage:
Static Object: #object Add [ObjectID] 0 Model [SizePercent] [SolidType] [Incline]
Tradeskill Object: #object Add [ObjectID] TypeNum Model Icon
Examples:
- #object Add 0 CHEST1 50
- #object Add 17 IT66_ACTORDEF 1115
- #object Add 161001 0 FELBED 125 1 0
----------------
3. #object Edit - Changes a property of an object within the zone
Usage: #object Edit (ObjectID) (PropertyName) (Value)
- Static Object Properties: model, type, size, solidtype, incline
- Tradeskill Object Properties: model, type, icon
Examples:
- #object Edit 30005 model BARSTOOL1
- #object Edit 141073 icon 1116
----------------
4. #object Move - Moves an object to a new location
Usage: #object Move (ObjectID) ToMe|(x y z [h])
Examples:
- #object Move 34106 ToMe
- #object Move 1519 -25 50 0 256
----------------
5. #object Rotate - Changes an object's heading without changing its location
Usage: #object Rotate (ObjectID) (NewHeading)
Example: #object Rotate 5029 128
----------------
6. #object Save - Saves an object to the database.
Note: New objects spawned and changes made to existing objects are not saved to the database until #object Save is called on them.
Usage: #object Save (ObjectID)
Example: #object Save 51202
----------------
7. #object Copy - Copies object(s) from the current instance version into another
Usage: #object Copy All|(ObjectID) (InstanceVersion)
Examples:
- #object Copy All 1
- #object Copy 76209 5
----------------
8. #object Delete - Despawns an object and permanently removes it from the database
Usage: #object Delete (ObjectID)
Example: #object Delete 219538
----------------
9. #object Undo - Cancels changes made to an object and respawns it from the database
Note: Objects that have been spawned with '#object Add' but have not yet been saved to the database are deleted when '#object Undo' is used on them.
Usage: #object Undo (ObjectID)
Example: #object Undo 32109
----------------

SQL Changes Required: None.
Best thing now would be for people to bash the heck out of it and find any glitches, memory leaks, unexpected scenarios, etc. that I may have missed (e.g., did I forget a 'mysql_free_result(result)' anywhere and create a memory leak?).
Next things I could work on would be #door and maybe #groundspawn, utilizing similar functionality.

Bravo, Shendare, bravo! That is just awesome!
I will get this tested out right now and up on the SVN ASAP unless someone is already working on getting it put in. This is a HUGE help to anyone wanting to mess with objects and the related doors stuff will help just as much. Even before similar door commands are in, I am sure this could help to make adding doors much easier too. Great work! And yeah, that command is a doozy!

Awwe, compile error:
Code:

Maybe I missed something or messed something up while adjusting the formatting. All I really did was change the double spaces to tabs to make it uniform with the source code. I am going to check it over again and see if I can figure it out. Seems like it should work, since the doors code right above it is almost the exact same thing. BTW, that command in command.cpp is massive!
Here is the bit of code it is referring to:
Code:
while(iterator.MoreElements())
{
Object* object=iterator.GetData();
object->GetLocation(&ox, &oy, &oz);
if ((abs(ox - x) <= radius) && (abs(oy - y) <= radius) && (abs(oz - z) <= radius))
{
return object;
}
iterator.Advance();
}
Maybe it is just an issue with my libraries or gcc or kernel or something. I don't really know.

I've hit this in my "trying to learn C++ adventure". The *_s functions are Microsoft only. For sprintf_s you might try the POSIX snprintf:
Code:
int snprintf(char *str, size_t size, const char *format, ...);
Feature Test Macro Requirements for glibc (see feature_test_macros(7)):
snprintf(), vsnprintf(): _BSD_SOURCE || _XOPEN_SOURCE >= 500 ||
_ISOC99_SOURCE; or cc -std=c99
The functions snprintf() and vsnprintf() write at most size bytes
(including the trailing null byte ('\0')) to str.
This is from the man pages with glibc version 2.2 |

Note that I moved the code related portion of this thread into the Server Code Submissions section here:
http://www.eqemulator.net/forums/showthread.php?t=28916
Code related discussion should go there and any other comments on it should go here to keep the code thread as clean as possible.
P.S. I can't wait to try this command out once it compiles properly in Linux! |

hey guys can you only use objects from .eqg files or can you use em from .s3d files also. If so how do you add from an s3d file as they never show up do you add the whole line like CAMPFIRE_DMSPRITEDEF in the doors table
or do you just add CAMPFIRE or do you skip the DM and do CAMPFIRE_SPRITEDEF
