If I have several different objects grouped together as a family,is it the case I only have to give say a private variable to one of the objects within that family and the rest of the family group also have that variable?
No, if you want to use a family variable, use the family manager accessible in the project tab of the ribbon. This can add/remove variables from all objects in a family.
Thanks for the quick reply .In my game I have a sprite which is not in the family.This sprite can cover 4 of the 9 family objects.I check if the non family sprite is overlapping the family sprites.I then want to set a variable called "selected" for each of the covered sprites to 1 so that I can perform actions on only the covered sprites.I hope I have explained clearly enough.
If you want to set a private variable for a family sprite, then make sure it's visible (or add it) via the family manager. Then you can set it via events like any other variable.

[quote:lwafw3ee]If all objects in a family have a common private variable - must be named the same - effect, or behavior, then it is common to the family, and can be accessed in the event sheet editor.
