How to do animation properly

Hi,

I know this has been asked several times in similar topics but I still can't figure it out:

I want to animate a piston moving, it's just a x(t) coordinates with a rectangular shape around that represents the cylinder.

The way I did it works but there's a better way to do it (with "draw now" or something). Especially because my animation is either too slow, or too laggy. Ideally, I'd like to have a smooth animation which I can easily change the speed (i.e. real time, x0.5 slow motion, x2 speed up, ...).

How can I do that ?

Thanks ! Cheers

Here's the code that I did:

DATA.INPUT.ENGINE.Bore = 0.08;
DATA.INPUT.GEN.Stroke = 0.5;
DATA.OUTPUT.Position =

Answer 1

[J Chen]

Draw the cylinder first. Use the "rectangle" command in a loop to draw the piston, e.g.,

rectangle('position',[x,y,w,h],'FaceColor',[1 0 0],'EdgeColor',[1 0 0])

Update only the position of the rectangle object using the following commands

h = gca;
h.Children.Position = [x_new,y_new,w,h];

[Joris Naudin]

Hi thank you for your answer.

It returns an error when I use "h.Children.Position" so I tried with just "Rectangle.Position" then it worked!

Thanks

x_Piston = DATA.INPUT.RUN.x0 * DATA.INPUT.GEN.Stroke;
y_Piston = - DATA.INPUT.ENGINE.Bore/2;
PistonWidth = 1e-2;
PistonHeight = DATA.INPUT.ENGINE.Bore;
Piston = rectangle('position',[x_Piston,y_Piston,PistonWidth,PistonHeight],'FaceColor',[1 0 0],'EdgeColor',[1 0 0]);


Step = 500;
for t = 1:Step:1000%length(TIME)
    x_Piston = DATA.OUTPUT.Position(t);
    
    h = gca;
    Piston.Position = [x_Piston, y_Piston, PistonWidth, PistonHeight];
    pause(1)
end
