Actually, it can be implemented on any emulator. That picture on the page is of me on my personal server editing the map and statics through the god client. The RunUO devs probably will not implement it though due to the lack of public access to the client. If any of the devs want to implement though, even if its just for private amusement or whatnot, I would gladly assist them with the packets. I've made it my job to know how to handle them
The 0x61 Destroy Static packet is used to remove a static.
The 0x62 Move Static packet is used to shift the static item's position.
The 0x0A Edit packet has a subcommand for adding new statics.
All of the above alter the static files in some way and are sent by the client. The correct response to these packets is the 0x3F Update Statics packet.
The 0x47 New Terrain packet is used to change map tiles.
The 0x14 Change Elevation packet is used to alter map tile elevation.
Both of the packets above alter the map file and should be met with the 0x40 Update Terrain packet.
The specifications for all of these packets can be found within my
packet guide.
The great thing about editing the world through the god client is that multiple worldbuilders can meet on a development shard and build it together just like the OSI guys do it.
Edit - In response to your question about whether this can be used with the normal client:
Unfortunately, no. Though the normal 4.0.3A client
does process these packets, there is no way to make it save the data. To edit ingame you must login with the god client.
A good alternative would be to implement these packets in KUOC, that way it would be up to date and able to be distributed freely.
