difficult with setting boundry character drops off the screen.

I have set the boundries for my character to walk but when I click to move the character it moves slightly and then drops off the screen. I do not know why as that is outside the boundry?

Have you correctly set the animation center for each of your characters animations? If you haven't set the animation center for each of the characters animations & you change to one of said animations then it will likely look like your character disappears/moves off of the screen because of the offset caused by the incorrect animation center. The animation center you specify for each characters animations is used to position the character on the scene.

Have you accidentally created any stray nodes in the way borders section?  The way border requires a full circuit otherwise issues can occur.

I had set the animation center to the feet of the character which I thought was what I needed to do. I will check again thanks.
