Problem about check command's arguments

I'm trying to check a command's arguments before it's going to be performed like"/give xxx xxx" if its be in line with my requirements, but i only find "PlayerCommandPreprocessEvent " , i think it would only detect the players' actions, but i also want to do this on command blocks. Ideas?thx.

 

You are indeed looking for the PlayerCommandPreprocessEvent, and you're right about the fact that this won't detect Command Block commands. It also won't detect commands executed in console.

 

Server executed commands commands can be caught via the ServerCommandEvent. I don't think you can catch commands executed by command blocks.

 

There's also the ServerCommandEvent, which fires when the console executes a command, I'm not sure if it fires when command blocks do.

 

But it seems that it can't be cancelled.

 

mewsf Yes, you cannot cancel it.

 

bump.

 

You could have cleared up your previous thread, instead of making a new one.

You can always make your own command.
