@Zheng 随便写着玩的，见笑了

great code

Woww... it's great!! good job!!!

beautiful!

cool ,man , so classical

Awesome buddy !
Nice fun

It works only for QWERTY keyboards. Think about poor frechies with AZERTY, add customise keys option, please :-)

Type

opengl software

before you run the game. If that solves the problem, then the most possible explanation of the upside-down text is that your OpenGL driver does not work properly with MATLAB. You must either upgrade your driver/card, or stick to the software renderer.

Alternatively, you can run

opengl hardware
f = figure(1); title('Rightside up'); set(f,'Renderer','OpenGL');

and see if the problem could be reproduced.

Anyway, I do believe that a submission should be judged based on its overall quality instead of minor bugs that are not even caused by the program itself. So I would never rate until I truly understand what the program does, how to use the program and what causes the problems (if any). If you do find a bug in the program, a more constructive idea would be to report the bug with details so that the author could correct it, rather than leaving a bad remark that doesn't give much info.

Then again, I was just speaking from a developer's point of view; not even trying to change your style of criticism. do what you believe is correct.

steve:
I'm really sorry for the inconvenience but there IS a file named README.txt in the package, in which I explicitly stated
"!Run stl_StellariaMain to play!"

And may I ask you, please, read the manual before recklessly giving a low rating.

As for the upside-down text, I have never produced the same problem on all (10+) computers with different versions of MATLAB. I won't put too much hope on you but if you are still interested, please provide more details (your MATLAB/Win version, which text is upside-down, and so on) so I can fix the bug.

nice~

Mine comes up with an error. says batmaneq is undefined

An indispensable tool in everyday work! Should definetly be integrated in default MATLAB installations.

Wow, I'm overwhelmed by your depressed comments. I'm feeling suicidal now.

Okay, I know exactly what you are talking about. I designed the game in such a way that the game runs in the same speed on any machine. If an occasional lag happens, the game would try to skip some frames so that it could 'catch up'. If you pause the game and the internal clock is still ticking, the game would think it has encountered a super-long lag and after you resume playing, it would run 5 times as fast as normal until it catches up to where it should be.

The timing of the game relies solely on on tic/toc pair:
stageStartTime = tic;
...
currentTime = toc(stageStartTime);

Unfortunately, stageStartTime is just a number, not an object you can 'pause'. The only workaround I came up with is to record how much time the game has been paused, then after the game is unpaused, add the duration of the paused time to stageStartTime so that toc would behave as if the pausing has never happened.

I did have this problem at the early stage of development. I thought I have already solved it...Anyway, I'll check it out agian

Hi Daniel,

Are you running an earlier version of MATLAB?
As far as I know, MATLAB doesn't support 'plus' for 'int64' until R2010b.

As a workaround, you may change Line 221 to:

stageStartTime = uint64(double(stageStartTime) + pauseElapsedTime.*timer2sec);

Thanks for the comment Dave, but I failed to reproduce the same bug on my machine. Does it happen every time you pause the game?

the game is great!

Thanks Ryan. I have not thoroughly tested the game so it has to be buggy. Have you tried it? Is it running sluggishly on your computer?

BTW, I created this game to prove a point: It is possible to make a sprite-based arcade-style game with MATLAB. You know what my next goal is: Super Mario Bros.

Hi Dave,

I am afraid you have to add all the 'subfolders' (at least these three: Math, Stages, Util\midi) into your search path list.

Sorry for the inconvenience.

very nice code. well commented.
