Maybe it's useful for someone:
I've added 4 new blocks to recieve informations from friends and the player.
For example, your can use the picture url to show the profile pictures of the player and his friends in your game.
Friends Data List:
[ 0 ]
[ 0 ] Id
[ 1 ] Name
[ 2 ] Picture Url
[ 3 ] Picture is_silhouette (0/1)
[ 1 ]
[ 0 ] Id
[ 1 ] Name
...
Player Data List:
[ 0 ] Id
[ 1 ] Name
[ 2 ] Picture Url
[ 2 ] Picture is_silhouette (0/1)
Picture info:
The API only specifies the maximum size for profile images, not the actual size.
Square: maximum width and height of 50px.
Small: maximum width of 50px and a maximum height of 150px.
Normal: maximum width of 100px and a maximum height of 300px.
Large: maximum width of 200px and a maximum height of 600px.
You can set width and height as per your need. Though facebook doesn't return the exact size asked for, it returns the closest dimension picture available with them.
is_silhouette: If a friend has no picture selected (is_silhouette = 1)
