lpatcher to play custom maps on ranked servers for cod4

DPGmaximus · **Joined:** 28 Sep 2009 21:30 **Posts:** 39

This may even work for CoD5, but anyhow I was looking at iw_00.iwd and was thinking how it could be possible to run as many custom maps as you wanted on a ranked server without modifying the game out of unranked mode by editing the server_map.cfg as well as server_tdm.cfg by placing the names of the actual maps in those configs. However, I did notice that its not exactly that easy since when you start up a server then select a custom map that isn't on the iw3mp.exe's list of ranked server maps it prompts you with "a mod is needed to run custom maps".

aLuigi any chance you may know of the code for lpatcher to overide the check of custom maps so ranked servers can run custom maps? There is a ton of great custom maps made by great mappers and would be nice to play a few more maps for a change. Thanks again! :)

I have seen the function where is used that message (but please be precise when reporting these strings otherwise it takes more time to find them!) but is not much clear.

the following is the function:

it looks like if the map is found in a list then it calls the command "devmap map" but mine is only a simple guess so I'm sure of nothing and I can't replicate the problem.

anyway if you want a test try the following, it will not work for sure:

Yea your right it doesn't seem to work. I will have to work on this more. Thanks for your help though aLuigi.

I found out that in the iw_00.iwd that there is server_map.cfg. When looking in iw3mp.exe I noticed this:

loadArenas createserver_maps loadGameInfo LoadMods voteTypeMap callvote typemap %s %s

aLuigi maybe if LoadMods was turned off and server_map.cfg had other maps listed inside itself other than the default ones that maybe this will work?

remember that you are asking these things to a person who has never played or administered cod4 :)
and my experience with the other q3 based games isn't better

Its okay aLuigi. The way I look at it is you still no way more than people who have administered CoD games since they were released! Something has got to be telling the iw3mp.exe that there is a certain set list of approved maps. I wonder what that list is and what it says because it seems like it would be possible to simply hex edit the approved map list to whatever list we want.
