Mark component dirty in editor

[ze0nni]

Use Case

I am create component, who provides access to other compoent data.

Like this:

class MyBytton {
    @property(MyText)
    private _text: MyText;

    @property(CCString)
    get string(): string { retunr this._text.string; }
    set string(value: string) { this._text.string = value; }
}

Problem Description

This is work good in play mode.

I have problem in edit mode: Then I change MyBytton.string in editor inspector, I see how text changed in MyText. But then I save prefab -- MyText нет saved. I understand that I need to mark the component as "dirty" but I couldn't find how.

I saw there is a flag CCObject.Flags.Dirty and use it like this:

this._text.string = value;
this._text.node._objFlags |= CCObject.Flags.Dirty;
this._text._objFlags |= CCObject.Flags.Dirty;

But no result

When you change MyBytton.string and focus to another place editor will mark as dirty and the title will have change to xx.scene*

but if you want to know your text change event at inspector, you can use getter and setter as you provided and just add @executeInEditMode decorator

//add this decorator and this component will run on editor and you can use you setter and getter when on editor mode
@executeInEditMode
export class testComponent extends Component {
@property(MyText)
    private _text: MyText;

    @property(CCString)
    get string(): string { retunr this._text.string; }
    set string(value: string) { this._text.string = value; }
}

Success. This happens if you use prefabs
