lambda can't access private members

[EGYPTIAN CODER]

hello every one
I am building a game engine that separate actions from reactions(soon I will post it)
the reactions is lamba    functions  and the actions are every time two drawable objects collide
but there is a problem that lambda need to access private members
and every time I find my self in this situation I made this members public   but I think that this is very bad
temporary solution ;
so some help would would be great
