Caster Binders

Converting binders that accept one data type and turn it into another.

Overview​

Caster binders perform type casts. Unlike converters on regular binders, a caster binder implements the interface of the source data type.

AnyToStringCasterBinder​

Accepts any data type and converts it to string:

object? → IConverter<object?, string?>? → string → (a target TextBinder or other)

Implements IAnyBinder, so the Source Generator can attach it to any ViewModel property.

Inspector properties​

PropertyDescription
ConverterOptional IConverter<object?, string?> (default ObjectToStringConverter)

Modes: OneWay, OneTime.

ToStringCasterBinder<T>​

The typed version: accepts a concrete T and converts it to string:

T? → IConverter<T?, string?>? → string

Implements IBinder<T>.

Example​

[ViewModel]
public partial class DebugViewModel
{
    [OneWayBind] private Vector3 _position;  // Vector3 to be shown as text
}

In the Inspector:

  1. Add AnyToStringCasterBinder
  2. Bind it to Position
  3. Result: the Vector3 is converted to a string through ToString()
