我的问题是,每次用户移动摄像装置(由某处触摸显示屏和周围移动他的手指)的OnAreaTouched()任何精灵的方法,那就是意外的手指下,被调用,当运动结束(指被解除) .我已经将触发事件限制在event.getAction()==UP(在它被称为touchAreas的真正混乱之前),但这还不够.如果用户正在缩放或移动相机,则不应激活精灵touchAreas.
有什么方法可以区分OnAreaTouched-event和OnSceneTouched-event？哪一个被称为第一个,我可以压制另一个吗？
OnSceneTouched()方法(简化):public boolean onSceneTouchEvent(Scene scene, final TouchEvent event) {
boolean isZooming = event.getMotionEvent().getPointerCount() >= 2;
if (event.getAction() == MotionEvent.ACTION_DOWN) {
// REMEMBER FIRST TOUCHPOINT, TO KNOW IN WHICH DIRECTION TO MOVE
this.touchPoint = new Point(event.getMotionEvent().getX(), event.getMotionEvent().getY());
} else if (event.getAction() == MotionEvent.ACTION_MOVE) {
if (isZooming) {
// DO SOME ZOOM STUFF
} else {
// DO SOME MOVEMENT STUFF

课程是:
SimpleLevelLoader
EntityLoader
SimpleLevelEntityLoaderData
请帮我解决这个问题.
我正在做一个非常简单的应用程序,一个测试AndEngine的基本hello世界,我在运行它时遇到了一些问题:我将我的模拟器属性设置为RealMayo在他的视频中建议它应该可以工作但是我得到了这个错误而不是
07-23 13:10:23.014: E/AndroidRuntime(1485): java.lang.IllegalArgumentException: No EGLConfig found!
任何人都遇到过相同的情况,或者可能知道如何解决它？
我几乎不想让我们成为AndEngine ...因为一个简单的应用程序真的很难运行.
注意:我发现了一些帖子,但它们至少有3个月的历史,并且不久前修复了模拟器的使用.
无论如何谢谢!:)
我正在尝试将精灵附加到另一个精灵并将其附加到其父级后面.
这通常很容易,我之前在我的代码中只有一个 - 但由于某种原因,在一次实例中,它不起作用.
该过程通常是将父级的Z索引设置为某个数字,并为其子级分配较低的Z索引.这是代码,其中rect是父级,icon并附加到它; 两者都附加到父实体.然后我尝试了sortChildren()所有方法(rect,父实体,甚至是场景本身); 我知道这不是很有效,但我只是想知道是否有东西可以抓住.它没有.icon仍被吸引rect:
for (int i=0; i<levelsList.size(); i++) {
rect = new Sprite(i*(width+padding),
0,
width,
height,
levelSelectorSquareRed,
this.getVertexBufferObjectManager());
icon = new Sprite((rect.getWidth()-innerWidth)/2f,
(rect.getHeight()-innerHeight)/2f,
innerWidth,
innerHeight,
levelIcons.get(i),
this.getVertexBufferObjectManager());
rect.setZIndex(1);
icon.setZIndex(0);
rect.attachChild(icon);
rect.sortChildren();
levelSquares.attachChild(rect);
}
levelSquares.setPosition(0, (CAMERA_HEIGHT-height)/2f);
levelSquares.sortChildren();
levelSelectorScene.attachChild(levelSquares);
levelSelectorScene.sortChildren();
从逻辑上讲,这应该是矫枉过正并让它运作,但它不是/我错过了什么？
谢谢
在我的情况下,我没有使用RenderSurfaceView.我想拍摄我的场景的屏幕截图.但是当我保存屏幕截图时,它会显示倒置的镜像.不能理解我在这里做错了什么.
这是我的代码
attachChild(screenCapture);

final int viewWidth = (int)camera.getWidth();
final int viewHeight = (int)camera.getHeight();
Log.d("camera width", "View width :" + viewWidth);
Log.d("camera height", "View height :" + viewHeight);
File direct = new File(
Environment.getExternalStorageDirectory()
+ "/Word");
if (!direct.exists()) {
if (direct.mkdir())
; // directory is created;
}
screenCapture.capture(
viewWidth,
viewHeight,
direct.getAbsolutePath() + "/word"
+ System.currentTimeMillis() + ".png",
