Which Reactor?

Hi Gang,
I'm a bit confused right now... What I'm looking for is the reactor that
will tell me when a specific block has been deleted, or modified.

For both circumstances: I'd like to know it was deleted/modified from both
code (entdels, entmods, etc) and from the command lines (erase, ddatte).

I don't care about stopping the action, I just want to know that it has
occured.

I can trap ddatte easily enough, but that's the only one so far. I've
trapped delete, but I can't figure out which entity was deleted, (My block,
or a line)...

Any ideas?

Thanks for the help,
Nick

You'd more than likely want an editor reactor than an object reactor.

(If (previous (selection (contains (block name....do what ever...

editor reactor fire
return command issued
ssget previous selection
compare block name
if so - do what ever

; Example code...

(vlr-editor-reactor nil '(vlr-commandended . what-happened)))

(defun what-happened ( func val /)
(setq call-fun func
fun (car val)
)
(if (= fun "ERASE")
(progn
;do what ever
)
)
(princ)
)

Hi Nick

Use an object reactor with this events:
- :VLR-erased fire if the block will be deleted
- :VLR-modified fire if the block himself will be modified
- :VLR-subObjModified fire if an attribute will be modified
Watch also for:
- :VLR-unerased
- :VLR-modifyUndone

Cheers
