You need to new the Actor class to pass into the constructor. 

<pre><code> static void Main(string[] args)
 {
 Stage stage = new Stage();

 Actor actor = new Actor();
 MyActor myActor = new MyActor(actor);
 stage.AddActor(actor);
 }
</code></pre>

blocks|key|455194|text|很明显，您正在尝试创建一个没有传入Actor的MyActor：|type|unstyled|depth|inlineStyleRanges|entityRanges|data|455195|MyActor+actor+=+new+MyActor();|code-block|syntax|javascript|455196|而你只有一个MyActor的构造器，它接受一个参与者：|455197|public+MyActor(Actor+actor)|455198|当您说MyActor扩展了Actor时，您实际上是指它继承了Actor吗？如果是这样的话，也许您不应该尝试在MyActor中封装Actor。也许这就是你想要做的，但你只需要想一想。|455199|entityMap^0|0|0|0|0|0^^$0|@$1|2|3|4|5|6|7|O|8|@]|9|@]|A|$]]|$1|B|3|C|5|D|7|P|8|@]|9|@]|A|$E|F]]|$1|G|3|H|5|6|7|Q|8|@]|9|@]|A|$]]|$1|I|3|J|5|D|7|R|8|@]|9|@]|A|$E|F]]|$1|K|3|L|5|6|7|S|8|@]|9|@]|A|$]]|$1|M|3|-4|5|6|7|T|8|@]|9|@]|A|$]]]|N|$]]

You're clearly trying to create a MyActor with no Actor passed in:

<pre><code>MyActor actor = new MyActor();
</code></pre>

Whereas you only have a constructor for MyActor that takes an Actor:

<pre><code>public MyActor(Actor actor)
</code></pre>

When you say that MyActor extends Actor, do you actually mean it inherits from it? If that's the case, perhaps you shouldn't be trying to encapsulate an Actor within a MyActor. Maybe that is what you want to do, but just give it a bit of a think.

blocks|key|455267|text|我终于可以在舞台上画纹理了。有没有一种方法可以在舞台上绘制纹理，但使用的方法与我通常使用的不同：Link|type|unstyled|depth|inlineStyleRanges|entityRanges|offset|length|data|455268|在我开始在LibGdx中使用stage之前，我会像这样绘制纹理：|455269|public+class+MyGdxGame+extends+ApplicationAdapter+{

}|code-block|syntax|javascript|455270|}|455271|但在本教程中，它是以不同的方式构建的。我想在主类中画出所有的东西，但不知道怎么做。为了让上面的代码起作用，我在MyActor类中添加了一个绘图函数，现在看起来是这样的：|455272|public+class+MyActor+extends+Actor|455273|{|455274|private+Actor+actor;

I finally can draw textures on stage.
Is there a way to draw texture on stage but using different way than I using usually: <a href="http://www.gamefromscratch.com/post/2013/11/27/LibGDX-Tutorial-9-Scene2D-Part-1.aspx" rel="nofollow">Link</a>

Before I started using stage in LibGdx I draw textures like this:

<pre><code>public class MyGdxGame extends ApplicationAdapter {

private SpriteBatch batch;
private Texture texture2;

@Override
public void create () {

 texture2 = new Texture("trojkat.png");
 batch = new SpriteBatch();

}

@Override
public void render () {
 Gdx.gl.glClearColor(144, 96, 48, 0);
 Gdx.gl.glClear(GL20.GL_COLOR_BUFFER_BIT);

 batch.begin();

 batch.draw(texture2,1,1);

 batch.end();
}

@Override
public void dispose() {

 texture2.dispose();
}
</code></pre>

}

But in this tutorial it's built differently. I would like to draw everything in the main class, but do not know how to do it. To the above code had worked, in class MyActor I add a drawing function, it's now looks like this:

<pre><code>public class MyActor extends Actor
</code></pre>

{

<pre><code>private Actor actor;
Texture texture = new Texture(Gdx.files.internal("trojkat.png"));
public void draw(Batch batch, float alpha)
{
 batch.draw(texture,0,0);
}



public MyActor(Actor actor)
{
 this.actor = actor;
}



public Actor getActor()
{
 return actor;
}
</code></pre>

}

Is it possible to draw everything in the main class when I using the stage?

I have main class (it's only small part of this class):

<pre><code> ScreenViewport viewport = new ScreenViewport();
 stage = new Stage(viewport);
 Gdx.input.setInputProcessor(stage);

 MyActor actor = new MyActor();
 stage.addActor(actor);
</code></pre>

and MyActro class:

<pre><code>package com.mygdx.game;
</code></pre>

import com.badlogic.gdx.scenes.scene2d.Actor;

public class MyActor extends Actor
{

<pre><code>private Actor actor;

public MyActor(Actor actor)
{
 this.actor = actor;
}


public Actor getActor()
{
 return actor;
}
</code></pre>

}

Eclipse suggests to I should remove argument from constructor. What I do wrong?

Can't add actor to stage
