This was inspired by another (open source)cores method. Okay, more like copypasta, but I had to change some of it to work with MaNGOS. I'm not taking any credit for anything other than the edits.

There is also some SQL to make it work.

# Table structure for table 'gameobject_teleports'
#

CREATE TABLE "gameobject_teleports" (
 "entry" int(10) unsigned NOT NULL AUTO_INCREMENT,
 "mapid" int(10) unsigned NOT NULL,
 "x_pos" float NOT NULL,
 "y_pos" float NOT NULL,
 "z_pos" float NOT NULL,
 "orientation" float NOT NULL,
 "required_level" int(10) unsigned NOT NULL,
 PRIMARY KEY ("entry")
) AUTO_INCREMENT=800213 /*!40100 DEFAULT CHARSET=latin1 ROW_FORMAT=DYNAMIC COMMENT='Optional table to create custom portals'*/;

To implement this, make a gameobject with a type of 10 (goober), and make a matching entry in the gameobject_teleports table with entry being the id of the gameobject. The other coloumns are the destination and required level to use the portal. This can work with any gameobject display. If there is no entry in the gameobject_teleport table, the rest of the goober handler executes. There is no need to reload the table as it is accesed as needed so all changes made in the DB are immediate.

-still to work on: Returning a message to the player if their level is too low.

[balrok]

maybe a message can done with Source->GetSession()->SendNotification("Your Level is too low");

if you want to improve you patch further: move the mysql-query somewhere at the startup-loads (at the place where all gameobjects are loaded).. cause else this query will be called at every gameobject use, which is maybe to much for a larger server..

so just do at the beginning a query, give a variable in gameobject-class the teleportid (or whatever is needed - haven't looked close)

and then you just check at gameobject-use if teleportid is present or not..

but i believe this patch couldn't be applied to mangos.. i think such custom-features are not very welcome (also ahbot, jail couldn't get to mangos)

ps: also it would be great if you make 4spaces instead of tabs

[Lunera]

The only reason I have done it this way, is because I've used it before, so I know it works. It's a slightly modified ArcScript.

Now what I wonder is, wasn't there something in place at some point to use the mini-game gameobject type? That is 27 I believe. That method, from what I understand used the data fields for coordinates. If THOSE are cached at launch, then I could implement that method.

Does anybody have any info on this?

I'm not expecting this to make it into the master branch, or any branch even, I'm just doing this for the fun of the coding and seeing how things work.

[balrok]

ah i thought you want it to master, cause you used this formal title-design

i don't know about minigame-gameobjects (i even haven't heared, such exist^^)

i have done a quite similar thing for gameobjects, where i wanted that some gameobjects have extra-information

http://github.com/balrok/mangos/commit/2a61e79ce005732dcc13cb9654f43314e4bb2f3c

instead of adding this function to battlegroundmanger, you can add it to objmgr

and then, from inside gameobject::use you'll also have access to the objmgr and can ask if the gameobject has this special attribute

edit maybe this table is supposed to do such things - but i don't know anything about it

Hey, whenever I attempt to apply this patch I get an error about unknown line type on line 12.

Does this still work?

Thanks!

You can manually go in and add the lines, in fact it makes things a bit easier sometimes when there's hardly any changes.

[Blake]

So just paste line 11-49 in Gameobject.cpp or what?

Thank you for your help.

[henhouse]

Well hopefully you understand how the patch works. The "-" means to remove that line and "+" to add. So those are the changes. The lines that don't have those symbols are just for locating where to make the changes. In a text editor (I recommend Notepad++ for Windows) do a Find(Control+F) search of a line that isn't modified like "

Player* player = (Player*)user;" and then when you find it, press Enter a few times and copy + paste all the lines with the "+" to add them. Remember to delete the little plus signs though.

That's how you can manually add them. Works great when there's problems patching if it's small.

[Blake]

Ok, I did that but now it errors out when compiling, where do I paste that into Gameobject.cpp?

Thanks again.

[Patman128]

This patch is unnecessary. Just use gameobject_scripts and attach it to the object's guid (shouldn't it be the id instead?)

[Blake]

Wait.. do you mean its GO ID (Like when you make the object) Or the GUID from ingame when the object is spawned.

Thank you once again for your help.

[Patman128]

Look at http://wiki.udbforums.org/index.php/Gameobject_scripts

It's the guid for some reason.

[Blake]

Thanks for your help.

[LilaLauneTeddy]

It work's great. But i think its better to use GUID from object. Little stupid for every location to use new object.

[Lunera]

I tried that method and for some reason, I could not get it to work. Ah well.

[SkyRanger]

Does this patch still work for mangos 3.3.3a ?

i am looking for an method to include own portals.

Use gameobject_scripts like I said before.

[SkyRanger]

The requested URL /index.php/Gameobject_scripts was not found on this server.

.... :-(

Ur link doesnt work.

Anyway, i used another howto, but it doesnt work. i think, i open a new Thread, may b someone could help me.
