Why does actor start at different place?

Cowuniverse

I have a actor centered in the scene, but when I preview it goes to the far bottom left. All I have added was constrain its position to touch.

Attributes have to have some value and most attributes' default value is zero. So if you constrain an actor's position to x=0 y=0 it will be at the bottom left of the scene.

What you need to do is place that constrain behavior inside of a When Touch is Pressed or When Mouse Button is down rule (your choice) so that it doesn't constrain the position until the mouse is clicked or the screen is tapped.
