StartupCommands
Allows you to set commands that run on server startup.
About this Mod
This mod allows you to create commands that run on server startup.
There are 3 ingame commands you can use, /startupcommands, /addstartupcommand, and /removestartupcommad. All 3 have different uses.
/startupcommands allows you to see the current startup commands on your server as a list.
/addstartupcommand allows you to add a startup command to your command list, the command must be inside double quotes and not include a slash, (ex: "time set day").
/removestartupcommand allows you to remove a startup command based on number in the list. So, you can do /startupcommands which will tell you the number associated with your commands, then do /removestartupcommand (number of command to remove).
NOTE:
Commands execute 1 second apart from each other to make it sequential, this is so it is guranteed one takes place after another.
