The subject basically says my problem. Basically I have an ArrayList that stores all of my commands for my mod and HashMaps that store the details for each command. Then there's a registry class that loops through each command and registers it with Forge. However, instead of processing the command in the processCommand() method with Forge I use a command listener which has a few checks before it passes the arguments to the command method. This is where my problem comes in. The whole beginning part works perfectly, however once I get to actually using the command for some reason the ArrayList and HashMaps have no data stored in them anymore. I can't for the life of my figure out why and I'm hoping it's something stupid that I'm just not seeing.

 

Here's my CommandManager class:

And then my CommandHandler class:

And the class I use to loop through and register each command:

The method getLengths() is only for debug as well as most of the logging you'll see.

CommandHandler extends CommandManager

* Handler is supposed to act on data held in Manager

* You are using e.g:

if(!commands.contains(command))

The "commands" is an ArrayList that is currently in THIS CommandHandler (more precisely in Manager which you are extending).

 

CommandRegistry extends CommandManager

* Is yet another instance of Manager

* This one actually holds your registered classes/data.

 

You messed up this/other.

 

UNLESS - Note: There is possibility that I am not seeing code that is responsible for actually being exact opposite of what I am saying above (meaning: I am wrong and you just provided too few classes, you should ALWAYS post @Mod class and proxies if they are used).

 

EDIT

 

PLEASE USE 'static" keyword! This will save you from instances and is much more prefered in this case.

Here's my @Mod main class. You can see I register my commands in during FMLServerStartingEvent

And here's my CommandWrapper class:

I think I see what you're saying.. CommandRegistry and CommandHandler are running on different instances of CommandManager and the data was only stored during the CommandRegistry instance?

 

Also are you saying I should be making all of the Maps and Lists static?

Ahh never mind I think I get what you are saying. Haha I kind of feel stupid that I didn't think of just making them static, but I guess that's how it often is. Thank you very much!
