drag and constrain actor to specific position on screen

cmw333

I have been working on a jigsaw drag and drop style puzzle very much like a free app on the app store called "shape puzzle HD Free". With the help of T-shirtbooth I was able to resolve the issue of actors sticking together when another actor collided. My only issue now is I have invisible pieces in place and when an actor collides with with wrong piece I set it so it would go back to the start position. The issue as far as I can see is that the invisible actors are too close together. Is there a way to use "magnitude(x,y) to constrain one actor to a specific place on the screen when correct or send it back to the start position when it is the wrong piece. Hope this makes sense to someone out there. I can send you exactly what I have so far and you will understand the problem.

regards

Chris

The issue is only when the actors are butted up together and not when they are spaced out.

Yes, there is a way.

You can create a real self attribute named something like "HowFarAway"

and then in the draggable piece actor put in:

constrain: self.HowFarAway to magnitude(self.posX-(X coordinate of the position you want it to be constrained to when correct), self.posY-(Y coordinate of the position you want it to be constrained to when correct)

then you can make a rule saying that when the attribute HowFarAway is less than a number, constrain self position X and Y to the "correct" positions . In the otherwise you can put when att.HowFarAway is greater than a number, constrain the X and Y positions to the starting position.

Hi artonskyblue

thanks alot for your help but unfortunately I can't get it to work. I followed your instructions but it does nothing. Can I sent you my file that I'm working on for you to have a look at for me.
