I need help with an if statement problem.

I am working on a Matlab project for a class. I am still relatively new to Matlab but can somewhat comprehend a bit of it. My project is a game picker for if you want to pick a video game. I am making a smaller version of it then what it could be. It will most likely consist of a lot of if statements. Here is what I have so far:

Y=1
N=2
step1=input('Do you Want to play a game?\n Y or N\n');
If step1==N
fprintf('Then do something else because I cannot help with that')
else
step2=input('Do you know the name of the game you want to play?\n Y or N\n')
end

Any help is appreciated. I just want to be able to understand this stuff better.

Thank you

• works well if you replace If by if
• Matlab is case sensitive
• keep an eye on the little box in the upper right corner of editor window. Red indicates syntax error.

Thank you so much, I actually figured it out about five minutes after posting. Now I'm just trying to figure out if you can input and output text like the name of a game.

[Walter Roberson]

playername = input('What is your name?', 's');

[Star Strider]

Since you likely don’t have every game, expanding on Walter’s Comment, consider listdlg for the choices.

[Ian Meister]

Is there any way I can change the following code to display it using the fprintf or another function?

result1=input('enter the name of the game you want to play\n','s');
  clc
  fprintf('Congratulations you want to play %6.2','result1')

[Star Strider]

You need one of the input functions to get the appropriate information into your script. The fprintf call is correct, although you need to terminate the string with a carriage return and linefeed (\n):

fprintf('Congratulations you want to play %6.2\n','result1')

I would use the GUI functions such as inputdlg, listdlg, msgbox, questdlg, and others. They’re simply easier to program, and for the user to interact with. They also don’t mess up your Command Window. They require a minimal acquaintance with cell variables, but those are important to learn to use, regardless.

[Ian Meister]

How could I go about using msgbox, it looks better and like you said is easier to interact with? This is what I have so far:

result1=input('enter the name of the game you want to play\n','s');
clc
s=msgbox('Congratulations you want to play %6.2','result1')

[Walter Roberson]

 s = msgbox( sprintf('Congratulations you want to play %6.2s',result1) );

but using a %6.2s format is a pretty unlikely thing to do, even if it is technically valid.

[Ian Meister]

Thank you for the help. I ended up using:

result1=msgbox({'Congratulations you want to play', input('Insert the name of the game you want to play: ','s')});

This did what I wanted it to do and works which is great.

Alright So I've moved on from this part of the code and am working on a genre selection part. Is there a way to make a dialogue box come up which would display four different buttons each representing a different genre?

[Star Strider]

I would use inputdlg rather than input. For the genre selection, questdlg is likely best.

[Ian Meister]

step3=questdlg('Choose your games genre','Genre','Genre 1','Genre 2','Genre 3','Genre 4');

Would this work? I tested that it would pop up as a display box but haven't tested if it is functional as an input.

[Ian Meister]

I just realized that the separate genres have no meaning behind them. They're just buttons. Do I need to add a variable to the genre name and then use the variable name as the button?

[Walter Roberson]

"need"... maybe not. But it would be a good idea even if you do not need it.
