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
