For example i have 2 layouts - "city" and "world". In each there is plenty to do and i need to switch between them often.
But when i switch layout - all my changes are lost.
I believe thats basic functionality and there is somewhere checkbox "keep layout in memory", but i cant find it =((
Use the persist behavior.
How do i apply behavior to whole layout?
Develop games in your browser. Powerful, performant & highly capable.
Add the behavior to every object that can move from it's original position in that layout.
Or you can use a family to do so, with the persist behavior on the family.
