NXT Program ideas

[nxtboyiii]

Post your program ideas here!
It could be game ideas, useful program ideas, etc.

I may make a Tetris later (way, way later).

Or mess around with the original "Portals" idea. (Also way, way later.)

I'm thinking of making a line follower.

Did I mention my current projects? They are:

• Bezier Curve Follower (It can also move the robot to the specified coordinates in 2D Cartesian space [cm])
• Memory Manager

Possible projects I'll retake up:

• Virtual Keyboard
• SnakeWorm 2.0
• Something to do with Bluetooth, but I can't remember

I made a nice function called scanf. You choose the letters with the left and right buttons, center for next letter, and exit for done.

Virtual Keyboard? Got any code? Sounds interesting. I'v built one, too.
I saw your post on the Memory Manager. I built something like it.

The Virtual Keyboard project was abandoned (over a year ago) due to bugs in the compiler, but I think they should be fixed by now, so I'll start it again some time later.

The code is here.

This one's for Muntoo: Remember you made that NXC virus? I tried something like it with RobotC but it didn't work, cuz I wanted to make a passcode lock for my NXT. Might be something you could do in NXC?

[For reference, here's the "virus" he's talking about.]

Bluetooth functionality is limited in NXC... If you want the virus to spread, of course.

Otherwise (not as deadly):
! Startup.nxc:

Code: Select all

task main()
{
    bool correct = true;

    string pass = "DIE";
    char c = 0x20;

    for(unsigned int i = 0; i < strlen(pass);)
    {
        if(ButtonPressed(BTNLEFT, 0))
        {
            if(c > 0x20)
                c--;
            else
                c = 0x7F;

            while(ButtonPressed(BTNLEFT, 0));
        }

        if(ButtonPressed(BTNRIGHT, 0))
        {
            if(c < 0x7F)
                c++;
            else
                c = 0x20;

            while(ButtonPressed(BTNRIGHT, 0));
        }

        if(ButtonPressed(BTNCENTER, 0))
        {
            if(c != pass[i])
            {
                correct = false;
            }

            ++i;

            while(ButtonPressed(BTNCENTER, 0));
        }
    }

    if(!correct)
    {
        PowerDown();
        //RebootInFirmwareMode();
    }
}

It's a good thing I don't live in Germany...
