plackowski Posted January 7, 2015 Share Posted January 7, 2015 I'm interested in creating Snake using autolisp, but as far as I can tell, user input is required to get past a grread command. Is there anyway I can break the grread command if no input is received within amount of time? Quote Link to comment Share on other sites More sharing options...
Hippe013 Posted January 8, 2015 Share Posted January 8, 2015 I believe that I am understanding you correctly that you have grread setup with tracking. If the user does not move the mouse the code stays on grread. I haven't found a way to get past this. Quote Link to comment Share on other sites More sharing options...
Lee Mac Posted January 9, 2015 Share Posted January 9, 2015 You used to be able to supply continuous input to the grread function by including an expression to regenerate the drawing within the grread expression - though, this is not recommended. Here is an example to demonstrate: (defun c:tg2 ( / o p ) (setq p (getvar 'viewctr)) (setq o (vla-addcircle (vla-get-modelspace (vla-get-activedocument (vlax-get-acad-object))) (vlax-3D-point (cons (+ (car p) (/ (getvar 'viewsize) 5.0)) (cdr p))) (/ (getvar 'viewsize) 20.0) ) ) (setq p (vlax-3D-point p)) (while (= 5 (car (grread t 14 1))) (vla-rotate o p 0.0175) (command "_.regen") ) (princ) ) (vl-load-com) (princ) Quote Link to comment Share on other sites More sharing options...
