[Release] Game Type Changer

[SgtLegend]

Hi everyone,

This is my first time posting a plugin so bare with me, I know there is a similar plugin to the one that I'm releasing but I will explain the differences before you think I copied someone else.

Basically the main problem with MW3 at the moment is its hard for custom playlists to be used with custom game types there for anyone using the God Plugin and permissions plugin it isn't trivial as to how you switch the map with the correct game type assigned in the playlist.

What I have done is created a simple chat command that accepts the map name and DSR file name, of course its the same as another plugin but bare with me, the key difference is I have ensured only the maps defined in the plugin can ever be loaded and only if they do exist will they be loaded. If a map is found along with the specified game type two server commands will be issued; one that sets the map rotation playlist and another that rotates the map using the custom playlist that was just set.

In a nutshell it works like this:

• The plugin creates a new DSPL file in the admin folder
  
• Once created it adds a new playlist line for the map and game type
  
• Next it assigns the map rotation to the custom playlist
  
• Finally it rotates the map
  

Now the main problem with setting a custom DSPL file is that you lose the custom playlist previously assigned, to fix this issue on the map pre change I have set a check that looks for this custom DSPL file and switches the map rotation back to the DSPL file you had set previously.

There are some limitations/downsides to doing this and they are:

• The map rotation counter goes up so once the map rotates it sits at 2
  
• The !nextmap command reports the same map as been next because of the custom playlist
  
• You need to write the full name of maps and game types as its not smart enough to guess them for you
  
• When the map changes the !mr command will rotate to the to the first map in your playlist file
  

Now of course I'm still new to this so there may be a way to fix this but from my investigating there isn't but if you know a fix please let me know. So without further ado add the following into your sv_config.ini file.

Code:

[GameTypeChange]
dsplfile=default
// The name of the DSPL file you have set for your map playlist

Usage:

Code:

!gametype <map name> <dsr file name>
or
!gt <map name> <dsr file name>

Example: !gt dome INF_default

Changelog:

v1.3
- A hopefully completed list of all the DLC maps
- Slight improvements to the plugin

v1.2

Dayum, pretty good for your first post. XML commented code too, nice, nice. Keep up the good work.

[SgtLegend]

Thanks, I have another plugin that I will release in about 2-3 days time

[DidUknowiPwn]

Nice job senor. (fancy spanish n)

[SMIRNOFF2096]

I realy like ur plugin, but when I try to write "!gt dome tdm" it writes me smth like that: "Invalid mapname".
What's wrong?

The only reason for that message to appear is if the map doesn't exist in your zone/english folder, just for my sanity could you please ensure that zone/english/mp_dome.ff does exist as I'm not sure if any other folders ever exist within the zone folder.

[Nekochan]

You should add more folder names.
Like zone/japanese, zone/russian, zone/swedish etc

Is there a public list of these folder names as I would feel better with a 100% correct list in front of me to use

Actually thought of a much more full proof way of detecting the folders, will release an update soon.
