Cause¶
A read-only member is annotated with the [Export] attribute. Read-only members
can't be exported.
Rule description¶
Godot doesn't allow exporting read-only members.
// Read-only fields can't be exported.
[Export]
public readonly int invalidField;
// This field can be exported because it's not declared 'readonly'.
[Export]
public int validField;
// Read-only properties can't be exported.
[Export]
public int InvalidProperty { get; }
// This property can be exported because it has both a getter and a setter.
[Export]
public int ValidProperty { get; set; }
How to fix violations¶
To fix a violation of this rule for fields, remove the readonly keyword or
remove the [Export] attribute.
To fix a violation of this rule for properties, make sure the property declares
both a getter and a setter, or remove the [Export] attribute.
When to suppress warnings¶
Do not suppress a warning from this rule. Read-only members can't be exported so they will be ignored by Godot, resulting in runtime errors.
