Error while evaluating UIControl Callback.
显示 更早的评论
Hi there, my push button code does not work, it is almost identical to the code of a different pushbutton which is just to open a different GUI.
% --- Executes on button press in pushbutton1.
function pushbutton1_Callback(hObject, eventdata, handles)
% hObject handle to pushbutton1 (see GCBO)
% eventdata reserved - to be defined in a future version of MATLAB
% handles structure with handles and user data (see GUIDATA)
run game.m
% --- Executes on button press in pushbutton2.
function pushbutton2_Callback(hObject, eventdata, handles)
% hObject handle to pushbutton2 (see GCBO)
% eventdata reserved - to be defined in a future version of MATLAB
% handles structure with handles and user data (see GUIDATA)
run howtoplay.m
Error in
matlab.graphics.internal.figfile.FigFile/read>@(hObject,eventdata)attempt2('pushbutton1_Callback',hObject,eventdata,guidata(hObject))
Error while evaluating UIControl Callback.
Pushbutton2 works, pushbutton1 does not.

Is this the complete error message? We see, where the problem occurred, but usually the message contains a hint also, what the error is. Maybe there is a typo inside game.m?
Prefer to use functions instead of scripts. Calling a script through run ... is less smart and prone to bugs.

Accepting an answer means, that your problem is solved. Is this correct?

As its help clearly explains, run will run a script, but it will not run a function (e.g. a GUI main file).
PS: Avoid GUIDE. Writing your own code is better:

"Why does pushbutton 2 run correctly?"
Because the code inside does not throw an error. Presumably howtoplay.m is a script on the MATLAB search path.
