View source for Check slots, ip and port in config file before starting

=== Option 1 - Update values if they have been modified (requires database connection) ===
Go to the game's settings. Click on the Custom Scripts icon. Add the following script. After creating the script go to the game's settings and click on Update Existing Services. To test the script on a single game server go to the service settings and save. Then start the game server.

<span style="color:red">This script connects to the database. If the database is offline the script will fail. You should have "Ignore execution errors" checked in case the database connection is not available when the script executes.</span>

 '''Operating System:''' Any

 '''Script Engine:''' IronPython
 '''Event:''' Before started
 '''Ignore execution errors''' Checked

 #Load objects from database.
 clr.AddReference("TCAdmin.GameHosting.SDK")
 from TCAdmin.GameHosting.SDK.Objects import Server, Service, Game
 ThisService=Service(ThisService_ServiceId)
 ThisServer=Server(ThisService.ServerId)
 ThisGame=Game(ThisService.GameId)
        
 #Update values if changed.
 ThisServer.GameHostingUtilitiesService.UpdateConfigFileVariableValues(ThisService.ServiceId)

=== Option 2 - Prevent service from starting if values have been modified (no database connection required) ===
Go to the game's settings. Click on the Custom Scripts icon. Add the following script. This can also be configured as a global script.
'''After creating the script go to the game's settings and click on Update Existing Services'''. To test the script on a single game server go to the service settings and save. Then start the game server. If the IP, port or slots don't have the correct values you will see an error message.

Update the values of '''slots_regex''', '''ip_regex''' and '''port_regex''' with regular expressions to read the current values. Remember to escape \ to \\. By default these values are configured for San Andreas Multiplayer.

     if realport != allowport:

=== Option 3 - JSON config file ===
 This script updates the ip, port and slots in a config file with json format. This example is for Rage MP

 import clr;
 import System;
 clr.AddReference("Newtonsoft.Json")
 from System.IO import File, Path
 from Newtonsoft.Json import JsonConvert, Formatting
 
 configpath=Path.Combine(ThisService_RootDirectory, "conf.json")
 
 if File.Exists(configpath):
   contents=File.ReadAllText(configpath)
   jsondata = JsonConvert.DeserializeObject(contents)
   jsondata["bind"]=ThisService_IpAddress
   jsondata["port"]=ThisService_GamePort
   jsondata["maxplayers"]=ThisService_Slots
   File.WriteAllText(configpath, JsonConvert.SerializeObject(jsondata, Formatting.Indented))
