在MATLAB用户交互动画(User interactive animation in matlab

我试图使MATLAB用户交互动画。这是一个转换和整个屏幕旋转，用户必须点击它一个正方形。如果他们点击它，就会获得积分和动画将重复。如果他们点击空格（如除正方形内的任何地方）的动画将退出，你失去就会显示出来。我有动画使用两个功能几乎已经完成。一个创建注册鼠标点击动画和其他。到目前为止，我可以识别的鼠标点击，如果用户点击空白动画将停止，但如果用户点击多边形内的动画将不会重复。我不能确定如何修改我的代码，使动画将重复，直到用户点击空白。我在下面贴上我的代码。任何帮助将不胜感激。

动画功能：

function movingPolygon
global gUserHitPolygon;
global gCurrentXVertices;
global gCurrentYVertices;
gUserHitPolygon = true;
nSides =4;
%Polar points
r=1;
theta = pi/nSides * (1:2:2*nSides-1);

%Cartesisn points
x0 = r * cos(theta);
y0 = r * sin(theta);
nFrames = 100;
xx = linspace(0,10, nFrames);
yy = xx;

rr = linspace(0, 2*pi, nFrames);
h = figure;
set(h,'WindowButtonDownFcn',   @mouseDownCallback);

for i = 1:nFrames

    rX = [cos(rr(i)), -sin(rr(i))];
    rY = [sin(rr(i)), cos(rr(i))];

    x1 = rX * [x0; y0];
    y1 = rY * [x0; y0];

    x2= x1 + xx(i);
    y2= y1 + yy(i);
    gCurrentXVertices=x2;
    gCurrentYVertices=y2;
    y=fill(x2, y2, 'b');

    xlim([0,10]); ylim([0,10]);
    hold on;
    pause(0.000000003);
    if ~gUserHitPolygon
        clear GLOBAL gUserHitPolygon gCurrentXVertices gCurrentYVertices;
        break;
    end
    delete(y);

end
end

回调函数：

function mouseDownCallback(~,~)

global UserHitPolygon;
global CurrentXVertices;
global CurrentYVertices;


xVertices = gCurrentXVertices;
yVertices = gCurrentYVertices;

% if we have valid (so non-empty) sets of x- and y-vertices then...
if ~isempty(xVertices) && ~isempty(yVertices)

    % get the coordinate on the current axis
    coordinates = get(gca,'CurrentPoint');
    coordinates = coordinates(1,1:2);

    % if the coordinate is not in the polygon, then change the
    % flag
    if ~inpolygon(coordinates(1),coordinates(2),xVertices,yVertices)
       gUserHitPolygon = false;
    end
end
end

编辑：固定在回调函数中的一些错误。

简答

包括一个while循环动画

长的答案

无论用户做什么，动画只能播放一次，因为它不知道重复。这个问题的答案是使用while循环，直到你告诉它停止将重复动画。你的主循环就变成

done = false; % your stopping condition
while ~done
    for i = 1:nFrames

        rX = [cos(rr(i)), -sin(rr(i))];
        rY = [sin(rr(i)), cos(rr(i))];

        x1 = rX * [x0; y0];
        y1 = rY * [x0; y0];

        x2= x1 + xx(i);
        y2= y1 + yy(i);
        gCurrentXVertices=x2;
        gCurrentYVertices=y2;
        y=fill(x2, y2, 'b');

        xlim([0,10]); ylim([0,10]);
        hold on;
        pause(0.000000003);
        if ~gUserHitPolygon
            clear GLOBAL gUserHitPolygon gCurrentXVertices gCurrentYVertices;
            done = true; % set your stopping condition
            break;
        end
        delete(y);

    end
end
