Question

我们正在尝试使用不同颜色和大小的点来模拟移动的汽车（汽车类型1：红色尺寸20，汽车类型2：绿色尺寸40等等），问题是如果有两辆相同类型的汽车他们它们应该相互跟随的重叠，这是使用过的代码：

x = linspace(0,30,1000);
axis([0,20,-0.4,1.5]);
ax = gca;
h = hgtransform('Parent',ax);
type1=plot(-1,0.4,'s','Parent',h,'MarkerFaceColor','red','MarkerSize',20);
type2=plot(-1,0.4,'s','Parent',h,'MarkerFaceColor','green','MarkerSize',40);
car=[1 2 2 1 1];
for k = 1:10:700
    for i = 1:length(car)
       if(car(i)==1)
           set(type1,'XData',x(k),'YData',0.4);
           pause(0.1);
       elseif(car(i)==2)
           set(type2,'XData',x(k)-3,'YData',0.4);
           pause(0.1);
       end
    end
end

如何保持每辆（x = 3）新车开始移动的顺序而不删除或重叠前面的车辆。

非常感谢

您可能需要以下代码。

x = linspace(0,30,1000);
axis([0,20,-0.4,1.5]);
ax = gca;
car=[1 2 2 1 1];
h = hgtransform('Parent',ax);
Ncar=length(car);

for n=1:Ncar %generate 5 cars having one type among type1 and type2
    if car(n)==1;
       types(n)=plot(-1,0.4,'s','Parent',h,'MarkerFaceColor','red','MarkerSize',20);
    else
       types(n)=plot(-1,0.4,'s','Parent',h,'MarkerFaceColor','green','MarkerSize',40);
    end
end

for k = 1:10:700 %plotting the cars sequencially
    for i = 1:length(car)  
           set(types(i),'XData',x(k)-3*(i-1),'YData',0.4);
       pause(0.1);
    end
end
