Im trying to make a Mario game gui using an arduino joystick as a controller. For some reason I keep getting an error in the loop where the mario sprites alternates and mario moves horizontally. Can anyone help with this? The code below is in the opening function of the gui.
 a = arduino('COM8','Uno');
[Sprites Spritesmap SpritesAlpha] = imread('some_mario_stuff_and_more_by_pokekoks-d4wzrc5.png');
handles.Sprites.Sprites = Sprites;
handles.Sprites.Mariorun1 = Sprites(181:1:213,89:1:121,:);
handles.Sprites.Mariorun2 = Sprites(219:1:251,9:1:41,:);
handles.Sprites.Mariorun3Jump = Sprites(220:1:254,127:1:161,:);
handles.Sprites.MarioStanding = Sprites(181:1:213,11:1:43,:);
Stage_UC = imread('Mario1_1.png');
Mario_Structure = load('mario_stages.mat');
handles.Template = Mario_Structure.Stage1_1.statMapInd; % or whatever it's called.
Stage = Stage_UC(1:1:227,:,:);
imshow(Stage);
axes(handles.TempAxis)
imshow(handles.Template);
axes(handles.MarioAxis)
imshow(Stage);
 axes(handles.MarioSpriteAxis)
 handles.Sprites = imagesc(handles.Sprites.MarioStanding);
 handles.Sprites.AlphaData = SpritesAlpha(181:1:213,11:1:43,:);
 axis off
 configurePin(a,'A0','AnalogInput')
 for time = [1:1:10000];
     A2Voltage = readVoltage(a, 'A0');
     CurrentX = 0;
if A2Voltage >= 3  
 handles.Sprites = imagesc(handles.Sprites.Mariorun1);
 handles.Sprites.AlphaData = SpritesAlpha(181:1:213,89:1:121,:);
 axis off
 pause(.04)
 handles.Sprites = imagesc(handles.Sprites.Mariorun2);
 handles.Sprites.AlphaData = SpritesAlpha(219:1:251,9:1:41,:);
 axis off
 pause(.04)
 handles.Sprites = imagesc(handles.Sprites.Mariorun1);
 handles.Sprites.AlphaData = SpritesAlpha(181:1:213,89:1:121,:);
 axis off
 pause(.04)
 handles.Sprites = imagesc(handles.Sprites.Mariorun3Jump);
 handles.Sprites.AlphaData = SpritesAlpha(220:1:254,127:1:161,:);
 axis off
 CurrentX = CurrentX + 1
 set(handles.MarioSpriteAxis, 'Position' ,[CurrentX 21.385 1.8 0.615]);
elseif A2Voltage < 2
 set(handles.MarioSpriteAxis,'xdir','reverse')
 handles.Sprites = imagesc(handles.Sprites.Mariorun1);
 handles.Sprites.AlphaData = SpritesAlpha(181:1:213,89:1:121,:);

Best Answer

You have, for example,
   handles.Sprites = imagesc(handles.Sprites.Mariorun1);
This replaces all of handles.Sprites with the output of imagesc(), which is going to be a primitive image() object. image() objects do not have Mariorun2 properties, so when you do
   handles.Sprites = imagesc(handles.Sprites.Mariorun2);
a few lines down, there is no Mariorun2 property to access.
