如何拖放演员在libgdx scene2d？ [英] how to drag and drop actors on libgdx scene2d?

问题描述

我正在开发一个游戏使用libGDX，我想知道我可以拖放一个演员。我做了我的舞台和绘制的演员，但我不知道如何来触发该事件。

请尝试使用自己的架构来帮助我。

 公共类MyGame实现了ApplicationListener
{
    舞台阶段;
    纹理质感;
    图片演员;

    @覆盖
    公共无效创建（）
    {
        纹理=新的纹理（Gdx.files.internal（actor.png））;
        Gdx.input.setInputProcessor（阶段）;
        舞台=新阶段（512F，512F，真正的）;

        演员=新的图像（纹理）;
        stage.addActor（演员）;
    }

    @覆盖
    公共无效渲染（）
    {
        Gdx.gl.glClear（GL10.GL_COLOR_BUFFER_BIT）;
        stage.draw（）;
    }
}
 

解决方案

看看在libgdx例子为例。这里是拖动和从libgdx测试类跌落试验：<一href="https://github.com/libgdx/libgdx/blob/master/tests/gdx-tests/src/com/badlogic/gdx/tests/DragAndDropTest.java"相对=nofollow> DragAndDropTest

如果你只是想拖/在你身边需要一个GestureListener添加到它，你的舞台传递到Inputprocessor这样的滑动你的演员： Gdx.input.setInputProcessor（阶段）; 。 这里是<一个href="https://github.com/libgdx/libgdx/blob/master/tests/gdx-tests/src/com/badlogic/gdx/tests/GestureDetectorTest.java"相对=nofollow> GestureDetectorTest 从libgdx。 对于拖动事件及其对Flinglistener。

I'm developing a game using libGDX and I would like to know how I can drag and drop an Actor. I've made my stage and drawn the actor, but I don't know how to trigger that event.

Please try to help me using my own architecture.

public class MyGame implements ApplicationListener 
{
    Stage stage;
    Texture texture;
    Image actor;

    @Override
    public void create() 
    {       
        texture = new Texture(Gdx.files.internal("actor.png"));
        Gdx.input.setInputProcessor(stage);
        stage = new Stage(512f,512f,true);

        actor = new Image(texture);
        stage.addActor(actor);
    }

    @Override
    public void render() 
    {       
        Gdx.gl.glClear(GL10.GL_COLOR_BUFFER_BIT);
        stage.draw();
    }
}

解决方案

Take a look at the Example in the libgdx examples. Here is the drag and drop test from the libgdx test classes: DragAndDropTest

If you just want to drag/slide your Actor around you need to add a GestureListener to it and pass your Stage to the Inputprocessor like this:Gdx.input.setInputProcessor(stage);. Here is the GestureDetectorTest from libgdx. For drag events its the Flinglistener.
