For updating your server, there is a few things you can do.
This list probably doesn't include all of them, but it has the common ones.
Also, these are typed in in the server console. Not the client one.
So if you're hosting a dedi, careful where you type this in.
Have Blockland refresh the file contents (but not re-execute):
setModPaths(getModPaths());
Execute a specific file, but note: contents won't auto-refresh:
exec("Add-Ons/Script_Name/server.cs");
Send all datablock files to the clients so they won't crash:
TransmitDatablocks();
Have their wrench dialogs update (spawning items, etc):
commandToAll('Wrench_LoadMenus');
Have their wrench event lists update / refresh:
for($var=0;$var<ClientGroup.getCount();$var++) { serverCmdRequestEventTables(ClientGroup.getObject($var)); }
