Do all fields of a class need to be encapsulated?

Question

OOP

Hello.
The question is actually all in the title.
Let's say there is a Player class (pseudocode):

class Player {
    string name;
    int cash;
    int level;
}

Should I create set and get functions like .getCash(), setName(), etc. for each field, even if no further action is taken?

Answer 1

What for?

Answer 2

Depends on how the class will be used.
One of the purposes of encapsulation is to reduce the likelihood that a class/module/function will be misused. In the extreme case, the class api should only allow correct usage. But the language does not always allow this.
