我试图在JME3中的Nifty GUI中创建一个图像按钮，但我的交互事件不起作用。我在android中运行我的应用程序。按钮似乎正在绘制，但事件不起作用。
这是我的控制：

</panel>
</controlDefinition>

我的应用：

/**

public class Main extends SimpleApplication implements ScreenController {
private Nifty nifty;
public static void main(String[] args) {
Main app = new Main();
app.start();
}
@Override
public void simpleInitApp() {
Box b = new Box(1, 1, 1);
Geometry geom = new Geometry("Box", b);
Material mat = new Material(assetManager, "Common/MatDefs/Misc/Unshaded.j3md");
mat.setColor("Color", ColorRGBA.Blue);
geom.setMaterial(mat);
rootNode.attachChild(geom);
NiftyJmeDisplay niftyDisplay = new NiftyJmeDisplay(assetManager,
inputManager,
audioRenderer,
guiViewPort);
nifty = niftyDisplay.getNifty();
nifty.setDebugOptionPanelColors(false);
nifty.fromXml("Interface/screens.xml", "start", this);
// attach the nifty display to the gui view port as a processor
guiViewPort.addProcessor(niftyDisplay);
// disable the fly cam
// flyCam.setEnabled(false);
// flyCam.setDragToRotate(true);
inputManager.setCursorVisible(true);
}
@Override
public void simpleUpdate(float tpf) {
//TODO: add update code
}
@Override
public void simpleRender(RenderManager rm) {
//TODO: add render code
}
public void bind(Nifty nifty, Screen screen) {
System.out.println("bind( " + screen.getScreenId() + ")");
}
public void onStartScreen() {
System.out.println("onStartScreen");
}
public void onEndScreen() {
System.out.println("onEndScreen");
}
public void buttonDown() {
System.out.println("buttonDown");
}
}
在那里制作Nifty GUI控件的例子很少，请帮帮我。
修改
到目前为止，我发现我是否这样做
flyCam.setEnabled(false);
flyCam.setDragToRotate(false);
我在控制器中收到了这些事件，但仍然无法在应用中点击
答案 0 :(得分：0)
漂亮的东西有点生疏，所以这可能不是答案，但也许有帮助。查看交互式标记是否仅在
的上下文中有效<control id="ddButton1" name="ddButton" text="Test" width="70%" visibleToMouse="true">
<interact ...>
</control>
查看nifty-button.xml，它似乎使用了一个inputMapping标记。所以也许它不是那么直接制作你的自定义按钮。
否则你可以尝试使用事件订阅者的模式：
控制器中的@NiftyEventSubscriber(id="ddButton1")
onButtonDown(final String topic,final ButtonClickedEvent event){
我发现这个漂亮的gui wiki在控制方面非常安全！ https://github.com/void256/nifty-gui/wiki/Controls 另外，查看源代码示例已经给出了很多。
祝你好运
