[1.7.10] How can I check if Minecraft is fully loaded?

[Ms_Raven]

I made an app that runs alongside my mod that displays various information on the features and content of the mod based on commands the user enters into it.

(Like entering 'lookup entity bombskit' would show a list of the mob's stats, entering 'lookup recipe backpack' would should a recipe grid for a backpack, etc)

All that should be fine.

 

But I want to disable command input in the app until Minecraft is completely loaded to avoid any bugs or crashes from referencing things that haven't loaded yet.

I thought about adding it to the EntityJoinWorldEvent but I'm not sure if that's the best place to do it, or if there's a better way altogether.

No, when I said it runs alongside my mod I meant it's created from within the mod. The window is created in the mod's preInit().

I didn't know how else I would get it to interact with it directly.
