# Claro v1.15.26 Objects and Classes
|
|
|
|
Claro objects are meant to stay plain and readable. Learners can start with variables and functions, then grow into classes when they are ready.
|
|
|
|
## Basic class
|
|
|
|
```claro
|
|
CLASS Player
|
|
HAS name TEXT
|
|
HAS score NUMBER
|
|
END
|
|
|
|
NEW Player player
|
|
SET player.name "Jon"
|
|
SET player.score 10
|
|
|
|
SAY player.name
|
|
SAY player.score
|
|
```
|
|
|
|
## Methods
|
|
|
|
Methods are taught with the same `TEACH` word used for normal functions.
|
|
|
|
```claro
|
|
CLASS Player
|
|
HAS name TEXT
|
|
HAS score NUMBER
|
|
|
|
TEACH show
|
|
SAY name
|
|
SAY score
|
|
END
|
|
|
|
TEACH add points
|
|
SET score score + points
|
|
END
|
|
END
|
|
|
|
NEW Player player
|
|
SET player.name "Jon"
|
|
SET player.score 10
|
|
|
|
DO player.show
|
|
DO player.add 5
|
|
SAY player.score
|
|
```
|
|
|
|
Inside a method, class fields such as `name` and `score` are available directly.
|
|
|
|
## Typed fields
|
|
|
|
Fields can have simple Claro types:
|
|
|
|
```claro
|
|
HAS name TEXT
|
|
HAS score NUMBER
|
|
HAS ready YESNO
|
|
```
|
|
|
|
When an object is created, Claro creates default field values and remembers their types. This means an accidental bad value can be caught:
|
|
|
|
```claro
|
|
SET player.score "oops"
|
|
```
|
|
|
|
will fail because `score` is a `NUMBER` field.
|
|
|
|
## Object helper commands
|
|
|
|
```claro
|
|
OBJECT CLASS player AS kind
|
|
OBJECT FIELDS player AS fields
|
|
```
|
|
|
|
These are useful for teaching and debugging.
