why does vlr-insert-reactor doesn't work?

[tangchang_21]

I want do some thing when a block was been inserted into autocad,so I make a reactor like this:

(vlr-insert-reactor nil '((:vlr-endinsert . vlr-trace-reaction)))

but it doesn't work when I have inserted any block. It seems like this reactor was never exsited.

Hope you can help me. Thanks.

Welcome to AUGI and congrats on your first post.

I have always used a command reactor for causing commands to fire when inserting a block.

(if    (not Command_Ending_Reactor)
      (setq Command_Ending_Reactor
         (vlr-command-reactor
           nil
           '((:vlr-commandended
          .
          Command_Ended_Command
         )
        )
         ) ;_ end of vlr-command-reactor
      ) ;_ end of setq
      () ;_ the reactor is already loaded
    ) ;_ end of if

then I define my command ended command with the in reactor name and the in command, and compare the in command to the command I am looking for, in your case "insert" or "-insert" If it matches, it will run the program.
