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
----------------
Okay, that's how they work.

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:
entity.cpp: In member function ‘Object* EntityList::FindNearbyObject(float, float, float, float)’:

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 |

Gah, portability issues from Microsoft, how utterly shocking.
No biggie, let me find the more portable versions of all of the functions that appear to be MS-specific and I'll post a quick diff here.

New version of entity.cpp (Line 579) - EntityList::FindNearbyObject()
Code:
Object* EntityList::FindNearbyObject(float x, float y, float z, float radius)
{
LinkedListIterator<Object*> iterator(object_list);
iterator.Reset();
float ox;
float oy;
float oz;
while(iterator.MoreElements())
{
Object* object=iterator.GetData();
object->GetLocation(&ox, &oy, &oz);
ox = (x < ox) ? (ox - x) : (x - ox);
oy = (y < oy) ? (oy - y) : (y - oy);
oz = (z < oz) ? (oz - z) : (z - oz);
if ((ox <= radius) && (oy <= radius) && (oz <= radius))
{
return object;
}
iterator.Advance();
}
return NULL;
}
Out of several options available for fixing the gcc ambiguity problem, I simply removed the abs() calls altogether in favor of conditional assignments. Probably more efficient anyway.

break;

c->Message(0, usage_string);
break;
}
}
In addition to changing the above-noted MS-specific function calls to the POSIX portable versions, I took advantage of the snprintf() function returning the assembled string's length to eliminate several unnecessary strlen() calls.
Heh, VC++ gave me "deprecated function" warnings after switching to the POSIX function usage. *shakefist @ MS*
Let me know if there's anything else gcc doesn't like.

On a read-through pass, I noticed a cosmetic glitch.
Line 13628 in command.cpp sends an error message that tries to refer to 'id' after it has been reset to 0.
The fix:
Code:
...
if (id == 0)
{
- c->Message(0, "ERROR: An object already exists with the id %u", id);
+ c->Message(0, "ERROR: An object already exists with the id %u", atoi(sep->arg[2]));
return;
}
...

Minor typo on Line 13980:
Code:
od.unknown008[1] = atoi(sep->arg[4]);
o->SetObjectData(&od);
c->Message(0, "Static Object %u set to SolidType %u. Change will take effect when you comit to the database with '#object Save'. Support for this property is on a per-model basis, mostly seen in smaller objects such as chests and tables.", id, od.unknown008[1]);

Once the #object command has been tested out and committed to the SVN, I'll get to work porting the functionality to #door and #groundspawn (I"ll probably give that one a '#gs' alias. Heh.)

MakeAnyLenString() would be preferable to your snprintf in this case, would of saved you a lot of time too, just have to remember to free the pointer it creates afterward.

Thank you Shendare! I got the changes in and it compiled perfectly this time. I also got it tested and everything I tried worked perfectly. I committed this to SVN R783. It is very cool to finally be able to have options to manipulate objects in game like that. The command will be a huge help to people in need of it, and will make easy work of things that were considerably more time consuming before this was available. So, great job!
From what I have seen so far, the only suggestion I might make would be a way to bool whether or not it is going to move your character when you do a ToMe move. In cases of dealing with large items, the move might be needed, but when trying to fine tune the positioning, it might be nice to just be able to move a slight bit and do another ToMe until it is perfectly placed. Also, having it report it's current loc after being moved that way would be nice, so you could then do an X Y Z move to tweak the position as well. Those are minor things and just things to consider for the future of this command.
I also played with trying to use it to spawn doors, but sadly, I guess door models don't play nice with object packets like I had assumed they would. I guess that anything with a IT<model number> that can be applied to an item as a graphic is considered an object, and anything without that is considered a door and they can't be used interchangeably between the packet types. That puts a bit of a damper on being able to have the option of using object packets to perfectly position doors. I am pretty sure we could still use door packets to do it, but unfortunately I know of no way to remove doors, so it will be a bit harder to do perfectly like with objects without having to restart the zone. If there was any case on live of something considered a door (that uses door packets) that disappears, we could collect that info and make use of it, but I am not aware of a single case of that happening on Live. Maybe ground spawns would work, but I think they work like object packets, so I kinda doubt it.
With the addition of the #object command, I can see other possibilities popping up to make use of spawning and despawning objects in real-time. If a quest command was made that could manipulate them in similar ways, I am sure neat stuff could be done with that. It probably wouldn't get used too often, but is just another neat idea possibility for the future.
Thanks again, Shendare! That is one heck of a chunk of code!

I still have some reservations on this, don't consider it final.

Yeah, KLS, MakeAnyLenString was certainly an option. I went with snprintf instead to lower a bunch of heap allocations I considered unnecessary. I can elaborate.
Utilizing snprintf, the memory for the string gets allocated just once at the beginning of the function, and is reused with each call to snprintf. The only caveat is to make sure I set aside a large enough buffer for all of my possible uses.
With MakeAnyLenString, for anyone reading who isn't familiar with it, the memory for the string is allocated with each MakeAnyLenString call, and re-allocated as many times as necessary within the function to fit the result string, starting with 256 bytes and doubling each time, re-performing the vsnprintf() call and its process time for each re-allocation as well. This means you don't have to worry about how large the string is, but it also means you could end up with three or four heap allocations per call for larger strings, and re-performing the vsnprintf() call for each allocation until you get one that fits within the buffer, potentially wasting time and fragmenting the heap.
If there's a standing dev preference for the use of MakeAnyLenString over snprintf, I have no problem changing the code to use it instead. I just felt I would explain why I didn't in this case, where the query string buffer might be re-used several times in a single function call.
As for your suggestions, Trev, at the very least adding a coordinate report in 'Move ToMe' is a simple and very worthwhile idea, requiring just one line addition at (what shows in my current source as) Line 14145:
File: command.cpp - object_command()
Code:
...
// GetHeading() returns half of the actual heading, for some reason
x2 = 10.0f * sin(c->GetHeading() * 2.0f / 256.0f * 3.14159265f);
y2 = 10.0f * cos(c->GetHeading() * 2.0f / 256.0f * 3.14159265f);
c->MovePC(c->GetX() - x2, c->GetY() - y2, c->GetZ(), c->GetHeading() * 2.0f);
+ c->Message(0, "Object %u moved to %.1f, %.1f, %.1f, heading %.1f", id, od.x, od.y, od.z, o->GetHeading());
}
else // Move to x, y, z [h]
...
Unfortunately, not bumping the player back when using 'Move ToMe' always caused problems during my debugging. The model would get summoned into my character's location at his feet, and because the model was always considered solid as a moveable tradeskill object, my character then either (1) couldn't move at all and I had to use #goto, or (2) got bumped up atop the object or bumped out of the object. Both rather throw a wrench in fine tuning location by moving your character slightly with another 'Move ToMe'.
However, adding the coordinate report before bumping your character back will allow numeric fine-tuning, at least, and was a very good idea. I should have thought to add it to 'Move' after putting it in 'Add'.
Now, what problem exactly were you having with door models, Trev? I was able to use FELDOOR2 and DOOR1 while debugging the command in Felwithe.
