Thought I'd jump in and save Xander *some* writing

In RobotC, there's functions for displaying graphics and sounds. The standard set of provided sounds is different, although there is overlap. You can find the original NXT-G sounds/images in a directory somewhere, I'm sure. But back to the question: "PlaySoundFile(const string &FileName)" will play the sound file you specify. You will have to upload the sound file to the brick first though (I think the file extension is ".rso").

For displaying graphics, check out this link (note that you can choose to display plain text as well; that takes up less memory on the brick): http://www.robotc.net/wiki/NXT_Function ... layRICFile

Thank you!
About the graphics: there's an Error about the file extension ".ric"... I don't know why.
I'll check it later again but try it by yourself. Maybe I'm doing something wrong... Maybe I'm not writing the names of the files as they are. For example - I have not seen any image named "faceclosed"... So I changed the name to Smile01.
I think the same problem about the sounds.

I have a terrible memory, I'm worse than one of those, ehh, orange things in a bowl of water.

I thought about that:




That could work, but you may want to use i instead of x.


You need to use nxtDisplayRICFile(nleft, nBottom, sFileName); where filename is the name of the .ric (picture) file. To play a sound, you must use PlaySoundFile(sFileName);One thing you'll have to do before you do that, is set the folder where ROBOTC can find these files. Normally it's set to the folder that is present if you have the LEGO Education version of NXT-G. There is a bug in ROBOTC it seems that stops this from working as it should. What I did as a work-around for this was to create a folder called "Resources" in the folder where I keep all my .c files. From C:\Program Files (x86)\LEGO Software\LEGO MINDSTORMS NXT\engine\Sounds and C:\Program Files (x86)\LEGO Software\LEGO MINDSTORMS NXT\engine\Pictures I copied the sounds and images into this new Resource folder that I created. Next I configured that folder in the preferences, here:

I set both the bottom folders to the same folder name, the one I just created. Now when I hit F5, they're automatically uploaded with the program!
This is a quick test program to see if it all works:

Ahhh... That's why our cow wouldn't moo last year. I uninstalled NXT-G.

OK guys, I wanna know if there is an option for the code to know when it comes to the last number in every grop.
I mean, here is 2d array:
image[i][j] = {{1,1,1,1,1,1,1,1,}, {1,1,0,1,0,1,1,0,}}
Now, I want when it comes to the 8th to do something but without write it like "when(j == 7)" but more in generally 'cause the I'm gonna change every time the amount of numbers in each group and I don't want every time to change also the number in the condition of the while loop...

How are you going to determine the amount of numbers in each group? Because when you declare your array, you'll be using that number. You can just use "if(j==var)", and "image[i][var]" instead. There's no rule forbidding the use of variables other than "i" and "j"

You might want to check that with the Programmers Guild, they're sticklers for this kind of thing.

I'm gonna change the amount of numbers in each grop by myself... So there's no way just to change the condition also by myself, right?
