I am trying to find out if there is a way to have different requirements based off of one of the arguments in a command. 

for example:

/testCommand string String
/testCommand player Elrol_Arrowsend

 

so the first one, would require a string, because the prior argument is string, and the second would need a PlayerEntity because the prior command is player.
 

I saw something about forks and I am thinking that it might be what I am looking for, but I am not too sure, so I figured I would ask.

You need to create a literal argument (Commands.literal) for "string" and call requires/then/execute on that as necessary and do the same for "player". In your main command registration (where you call CommandDispatcher#register), create a literal argument for "testcommand" and call then on it with the result of each literal method chain.

 

If string and player are more like separate commands than modes of the same command, you can move each sub-command into its own class with a static method that returns an ArgumentBuilder<CommandSource, ?> (the result of the literal method chain) and call these methods in the then calls of the main command registration.

 

See ForgeCommand or my TestMod3Command for examples of this.

Again, thanks for this info. This will make my commands much less of a headahce and far more organized.
