So far it's not a easy way for me to check the Position of player
against other items , i'd do some research first.

Cuz in my game , i've got lots of GraphicsItem , i don't need to check a
player Item with all of the rest , so i just play around with
 collidingItems() function , see if it hits any other item.

e,g I've got walls around at the bound of map , buildings inside the map
, any NPC whatever , i don't want my player 'hit' them , so only tried
with collidingItems() , just check if it's higher than zero.

Is that a good way for doing this ?

It's not good to list all of the Item on a QGraphicsScene , and check
the player with it right ?

Thanks Mihail.
