Control / Control Loss  Urgent!!!
May 14th, 2008, 9:45pm  
Hi there!

I'm developing a project but I'm having some problems with the code (I'm a newbie using processing)

The project is an user interaction object, the user controls /manipulates something, with the computer mouse, he can see the reflex of his actions on the screen: until this point everything is OK (I know how to do this).

But, I intend for the user to loose that control at some point, meaning: the "machines" takes over, it acts on its own for a while and then returns the control back too the user.

I would like too know if somone could help me with this, how can I do it, or if there are projects that use simillar code?  

Its for an Universisty project...so I'm really short on time!!

Thanks in advance!

You're going to want to look up the Robot class (http://java.sun.com/j2se/1.4.2/docs/api/java/awt/Robot.html) and read those docs.  I really hope you have ultimate control over the systems this needs to run on, otherwise you're going to have a lot of headaches getting the security issues worked out...

I've never personally used Robot for anything, maybe someone that has can give you more specific advice?

You can use, for example frameCount (or a time counter) to know when to take control and when to release it.
For example, I took the Reach2 demo, and added/changed the following lines:
 int mx = mouseX, my = mouseY;
 if (frameCount > 500 && frameCount < 700) { mx += random(-100, 100); my += random(-100, 100); }
 reachSegment(0, mx, my);
(last line it the original one I changed)
After a while, it acts erratically (but can have more sophisticated moves), then behave normally.

Oh thanks! Wink

I'm gonna try that!, I had already thought if I could use time or frames for this.

And I actually want it to be kind of erratic, so it suits my purposes. Cheesy
