| + | * instantiem diferit playerii: unul controlabil din input local, pentru clientul curent, si ceilalti doar sincronizati la actualizarile din server | ||

| + | * actualizam sincronizarile din server pentru toti playerii. Pentru asta in general avem nevoie sa tinem minte toata lista de clienti | ||
| + | <code> | ||
