Object movement, 2D environment

I want to do following tasks: 1. create two square objects 2. Two objects move 2D environment.

Thanks a lot

Dat - what have you tried so far? Are you using Simulink or are you just creating/plotting two squares and then moving them according to some motion model?

Or do you want to move them with the mouse? Maybe you want to control a robot using Simulink to move real objects?

i just want to create creating two squares and moving them in my model. And save this model as a video. Then, i will process in this video.

@DAT VUONG: We cannot read your mind and in consequence we cannot know, what "creating two squares" exactly means. "Moving them in my model" can mean a variety of things also. At least "saving as a video" seems to imply, that you mean 2D or 3D graphics.

Please give us a chance to help you and ask much more specifically.

Thanks for your comment. Actually, i want to create a 2D environment where two objects with Square shape move to identified direction. How can i do that? thanks.

Dat - one solution may be to use rectangle. You would draw the rectangle/square within an axes and then, using the handle to the rectangle object, change its position to "move" the square. For example,

 f = figure;
 axis([-100 100 -100 100])
 mySquare = rectangle('Parent',gca, 'Position',[0 0 5 5])

So this will create a rectangle whose lower left corner is at (0,0) and whose width and height is five. You can then move the square by changing its position

 set(mySquare,'Position',[1 1 5 5])

You should be able to extend this to two (or more squares) and move them around your 2D environment (defined by the axes dimensions).
