Try to rename these properties, right in this kind of fashion:
this._x = this.x; => this.x = this._x; this._y = this.y; => this.y = this._y; this._w = this.w; => this.w = this._w; this._h = this.h; => this.h = this._h;
Read and sort horizontal, as usually.
→ this._x = this.x; → this._y = this.y; → this._w = this.w; → this._h = this.h;
Read and sort vertical, as a chinese.
↓ ↓ this._x = this.x; this._y = this.y; this._w = this.w; this._h = this.h;
