Help plese

hello,
I am trying to make king of a pokemon engine/rpg game using your server
it works well but I have a sync problem:
my player object and my other player object have the same movement code(grid based movement) abd when another player logs in I the sprites are wrong (It shows my block object sprite insted)

moreover,
when a second player logs in it cant see the first player, only the first can see the second.
please answer as quickly as you can and thank you
