This is a piece of pseudo-code that indicates that I have initialized 2 ways of listening to the mouse at the same time.
protected void initialize(Application aplctn) {
CursorEventControl.addListenersToSpatial(simpleApp.getRootNode().getChild("MapNode"), new DefaultCursorListener() {
@Override
protected void click(CursorButtonEvent event, Spatial target, Spatial capture) {
// System.out.println("我被点击了:" + target);
// System.out.println("我被点击了:" + capture);

event.setConsumed();

yDown = event.getY();
System.err.println(results.getContactPoint());
//BOX(scenarioState.mapGrid3D.getPutPlaceBuildingCoordinates(results.getContactPoint(),new Vector2f(3,3)));//向网格内添加建筑
// 鼠标按下，记录起始位置
startClick.set(inputManager.getCursorPosition());
isSelecting = true;
} else {
float x = event.getX();
float y = event.getY();
//它检查鼠标在释放按钮时是否移动得很小（小于3个像素）。如果是，它调用 click 方法
if (Math.abs(x - xDown) < 3 && Math.abs(y - yDown) < 3) {
click(event, target, capture);
}
isSelecting = false;
startClick.zero();
endClick.zero();
updateSelectionBox();
}
}
@Override
public void cursorEntered(CursorMotionEvent event, Spatial target, Spatial capture) {
// System.err.println(event);//.getCollision().getContactPoint()
}

}

GuiGlobals.initialize(simpleApp);
inputMapper = GuiGlobals.getInstance().getInputMapper();
// inputMapper.map(F_X_ROTATE_MOUSE, Axis.MOUSE_X);
MouseInputMap.initializeDefaultMappings(inputMapper);
MouseInputActions mouseInputActions = new MouseInputActions();
inputMapper.addStateListener(mouseInputActions,MouseInputMap.Left_MOUSE_CLICK);
inputMapper.addAnalogListener(mouseInputActions, MouseInputMap.Left_MOUSE_CLICK);
inputMapper.activateGroup(MouseInputMap.MOUSE_GROUP);
}
Something happens to inputMapper.addAnalogListener when both types of listeners are present at the same time.
This video shows how lifting the mouse when I press the left mouse button and dragging into the terrain inputMapper.addAnalogListener seems to conflict with CursorEventControl.addListenersToSpatial even though my mouse state is off inputMapper. addAnalogListener is still called.
I have to click the left mouse button again outside of the map (i.e., where CursorEventControl.addListenersToSpatial can’t detect it) in order to undo the call to inputMapper.addAnalogListener
Is this how lemurs were originally designed? Or am I using this class incorrectly?
