Need help moving text inside of a figure window

Hey, Im trying to move a person's name (using input) and moving around in different directions in a figure window, but the text must hit the edges of the figure window like an old DVD logo type thing. Here is what i got so far:

    % 
clear
close all
clc
x = 0;
y = 0;
Name = input('Please input your name: ','s');
TH = text(x,y,Name);
axis([-1 1 -1 1]);
for i = 1:360
    x = x + 0.01;
    y= y + 0.01
    set(TH,'Position', [x y 0]);
    pause(0.01);
end

Thanks!

Dear Jacob,

In your code you miss the instruction to change the direction of the text. The text object is defined only by the coordinates of the bottom left corner, so one would need to calculate the size of the text box and modify the value of the edge where the direction has to be changed. Therefore, long names need a "lower edge value" on the right.

clear
close all
clc

x = 0.4;
y = 0.0;
Name = input('Please input your name: ','s');
TH = text(x,y,Name);
axis([-1.3 1.3 -1 1]); %you need a rectangle for the "DVD-effect"
i = 1;

%define initial direction (up-right)
dx = 0.01;
dy = 0.01;

while i == 1

      % Change UP-DOWN
      if y == 0.95 %instruction to go down
          dy = -0.01; %delta y
      elseif y == -1%instruction to go up
          dy = 0.01; 
      end

      % Change LEFT-RIGHT
      if x == -1.3 %instruction to turn right
          dx = 0.01;
      elseif x == 1.25 % instruction to turn left
          dx = -0.01;
      end

      % Calculate new positions
      x = x + dx;
      y = y + dy;
      x = round(x, 2);
      y = round(y, 2);

      %set new position
      set(TH,'Position', [x y 0]);
      pause(0.01);
  end

The code above works but is not optimal, I let you find the best parameters.

Best, Sandro
