the simple undo!?

[MaxStudio]

I created multiple objects with a script. Is there some way with scripting that I can undo all the objects(the entire script) with just one undo click?

Have a look at putting begincontext and endcontext around the area that you want to treat as a whole entity. It works similar to database commits where you can rollback a whole set of commands if any single operations fails, but it may do the trick for you too if you set the 'undo click' to endcontext(0) - rollback.

That said, a script is treated as a single operation, so running a script, then hitting undo will remove everything created under the script.

PROCEDURE test;

VAR 
pt : POINT;

BEGIN
BeginContext;

Rect( 1000, 1000, 1500, 1500 );
Rect( 2000, 2000, 2500, 2500 );
Rect( 3000, 3000, 3500, 3500 );

GetPt(pt.x, pt.y);
IF ( pt.x < 1000 ) OR ( pt.y < 1000 ) OR ( pt.x > 3500 ) OR ( pt.y > 3500 ) THEN
	EndContext(0)
ELSE
	EndContext(1);
END;

RUN( test );

The above shows the use of the context - it will create 3 'ghosted' rectanges, but not 'commit' them until you click within the bounds of the cluster. If you click outside the bounds, the operation within the context will be rolled back - ie, treated as it had not occurred.
