Hi, I hope I can explain this well.
I am working on a top down scrolling shooter.
To prevent the Y scroll affecting the bullets, I have to use a seperate layer for them with Y scrolling at 0%
The player sprite and bullets are also on this layer to prevent any weird movement on Y as the speed of scrolling changes.
I have ground based enemies on the scrolling background but my player bullets are not colliding with the enemy family.
in short, my ground enemies are locked to the scroll, but my bullets are not, and I cant get them to interact via families..
