Question

我正在将一组对象插入到具有图像rect的父组中，据我所知，例外结果应该是外部组将从屏幕的左上角开始（0,0）内部组将引用父组的左上角，实际上就像我在外组中没有图像rect所描述的那样，问题是当外组的内部有一个图像时，所以外组中心点是在屏幕的左上角，内部组是否在父组的中心？

发生了什么事？请帮忙......

local checkinContent = display.newGroup();
local BG= display.newImageRect(checkinContent,"images/magen-david_backgound.png",display.contentWidth, 0.45822 * display.contentHeight);

checkinContent:setReferencePoint(display.TopLeftReferencePoint);
checkinContent.y = display.contentHeight - checkinContent.height;
checkinContent.x = 0;

local circlesGroup = display.newGroup();
circlesGroup:setReferencePoint(display.TopCenterReferencePoint);
circleTable[0] = display.newImageRect(circlesGroup,"images/circle.png",0.0265 * display.contentWidth, 0.0265 * display.contentWidth);
circleTable[1] = display.newImageRect(circlesGroup,"images/circle.png",0.0265 * display.contentWidth, 0.0265 * display.contentWidth);
circleTable[2] = display.newImageRect(circlesGroup,"images/circleCurrent.png",0.0265 * display.contentWidth, 0.0265 * display.contentWidth);

circlesGroup.y = 0;

checkinContent:insert(circlesGroup);

好吧，有时日冕就像在黑暗中行走...... 这是一个video的答案..

视频中的关键句是：

“奇怪的是，一旦这个被创建，并且就位，它会改变参考点到中心......为什么？！我没有怪异的想法......”

更新以下代码行：

local circlesGroup = display.newGroup();
circleTable[0] = display.newImageRect(circlesGroup,"images/circle.png",0.0265 * display.contentWidth, 0.0265 * display.contentWidth);
circleTable[1] = display.newImageRect(circlesGroup,"images/circle.png",0.0265 * display.contentWidth, 0.0265 * display.contentWidth);
circleTable[2] = display.newImageRect(circlesGroup,"images/circleCurrent.png",0.0265 * display.contentWidth, 0.0265 * display.contentWidth);

checkinContent:insert(circlesGroup);
circlesGroup:setReferencePoint(display.TopCenterReferencePoint);
circlesGroup.y = 0;
