Keeping items when making game

[IIMikII]

Hey i want to make a game where you have to look around in different places and find objects to figure out where to go.
but i dont know how to make it so once they pick up a object to have it stay and if they go back a to a different location the object is still with them on the screen.
thx

Too complex question for me, my MMF skill and my english.
But i suggest looking into Knytt source.

Great place for getting ideas.
For this particular problem look into "Pick up Ufo Part" and "item list" groups.

I remember a while ago someone made an application that used what you are requesting.
