AS3.0：访问创建的实例的子属性

发布于 2024-11-10 13:44:40 字数 579 浏览 3 评论 0原文

在我的时间轴上，我使用以下代码创建了类 FirstClass 的新实例：
var firstObject:FirstClass = new FirstClass();

该类如下所示：

package  {
    public class FirstClass extends MovieClip {
        public function FirstClass() {
            var tempObject:SecondClass = new SecondClass();
            tempObject.x = 100;
            tempObject.y = 200;
        }
        public function getTempObjectXpos():Number{
            return tempObject.x;            
        }
    }    
}

在我的时间轴上，我想访问对象 tempObject 的 x 位置，任何人都可以帮助我吗？

原文

on my timeline i create a new instance of the class FirstClass with the following code:
var firstObject:FirstClass = new FirstClass();

the class looks like this:

package  {
    public class FirstClass extends MovieClip {
        public function FirstClass() {
            var tempObject:SecondClass = new SecondClass();
            tempObject.x = 100;
            tempObject.y = 200;
        }
        public function getTempObjectXpos():Number{
            return tempObject.x;            
        }
    }    
}

On my timeline i would like to acces the x position of the object tempObject can anyone help me ?

您必须将 tempObject 声明为 FirstClass 的成员。
如果对象不是此类的成员，则不能在类的不同方法之间使用对象（如果准确的话是对象引用）。

更正后的代码：

package  {
    public class FirstClass extends MovieClip {
        public function FirstClass() {
            tempObject = new SecondClass();
            tempObject.x = 100;
            tempObject.y = 200;
        }
        public function getTempObjectXpos():Number{
            return tempObject.x;            
        }

        private var tempObject:SecondClass = null;
    }
}

You must declare tempObject as a member of FirstClass.
You cannot use objects (object references if be exact) between different methods of a class if they aren't members of this class.

Corrected code:

package  {
    public class FirstClass extends MovieClip {
        public function FirstClass() {
            tempObject = new SecondClass();
            tempObject.x = 100;
            tempObject.y = 200;
        }
        public function getTempObjectXpos():Number{
            return tempObject.x;            
        }

        private var tempObject:SecondClass = null;
    }
}
