[ENDED] (Results Soon) Code Golf - The Reboot #2

[pimathbrainiac]

Challenge #2: Motion Commotion
The challenge: Make a program that moves a pixel around the screen.

Inputs:
You may either use the arrow keys or wasd for input.

Outputs:
Each time a key is pressed, a pixel moves around the screen as follows:
up/w: up 1 pixel
down/s: down 1 pixel
left/a: left 1 pixel
right/d: right 1 pixel
If a key is held, it doesn't matter. 1 pixel of movement per press.

Scoring:
All non-calculator programs will be scored through this counter: http://juju2143.ca/golf/
Assembly programs will be scored on binary size (excluding the header), and Basic/Axe programs will be scored bn on-calc source size (once again, excluding the header).
Good luck, and may this contest move you!

Sounds fun. What do you mean by pixel, at least on PC? An actual pixel? Or it can be a *?

[pimathbrainiac]

An actual pixel, preferably black.

An actual pixel, preferably black.

In a window or on the whole screen? Anyway, sounds like it requires a few graphic libraries.

Either works, and yeah, that's the point. This one gives advantages to calcs.

[Juju]

Yeah, I see, or any language with integrated graphics

Also some more questions: I have to erase the pixel before moving it, right? Also can I allow it to go out of bounds?

EDIT: pimath says yes and no no and yes, respectively. Sorry for all the questions, I think I'm done

[Scipi]

I've taken a stab at it in C again and my first attempt is 155 bytes. I've targeted the GBA to make things much shorter.

[ordelore]

Is there any specific size the window should be if we are making a computer program?

[pimathbrainiac]

Is there any specific size the window should be if we are making a computer program?

No. That is not a restriction.

[lirtosiast]

Do we need to initialize the cursor at any specific location, do we need to clear the screen first, and can we assume that the only pressed keys will be up, down, left, and right?

[pimathbrainiac]

no, no, and yes.

[lirtosiast]

Okay, I have 34 bytes in TI-BASIC, and that includes clearing the screen and starting the cursor at (0,0).

30 bytes if we don't need to initialize the cursor and it only works for a few seconds

[Ivoah]

11 bytes in TI-BASIC :p

[lirtosiast]

I fixed my solution; now it doesn't repeat keys.

[pimathbrainiac]

Ivoah: Wow! (assuming your solution is correct)

My answer is actually wrong because the keys repeat, and it will cost about 5 bytes to fix.

Well he was wrong. Don't worry Same thing with the key repeat and also a perceived loophole that wasn't actually there
