Hi, I have a class with the variable lvl=1;.  
the problem is I want to display the “1” in draw by doing something like this:  
text(“lvl”,200,200,100,100);  
however this doesn’t work

Try

```auto

 text( objectName.lvl,200,200,100,100);

```

instead

it’s objectName then a dot and the lvl

I have tried but it just says:  
the function “text()” expects parameters like: "text(char[],int,int,float,float);

is lvl an int?

This works:

```auto
size(555, 555);
text( 8, 200, 200);

```

maybe show a bit of your class?

frisk is the class name (convention: should be Frisk with capital letter F)

you need a object of this class

(lv or lvl ?)

this looks not good: `frisk frisk;`

this works:

```auto

Frisk frisk1=new Frisk(); 

void setup() {
  size(555, 555);
  text( frisk1.lv, 200, 200);
}

class Frisk {
  int x;
  int lv=2;
  int exp;
  int hp=20;
  int maxhp=20;
}

```

“Frisk frisk1=new Frisk();” does?

The class Frisk (capital letter F) is the **cookie maker** (= class), the frisk1 (small letter f) is the **cookie** (= one object instantiated from the class). In this line we make a cookie.

You can have many cookies derived from the same class.

See tutorial I linked to above…
