[ENDED] (Results Soon) Code Golf - The Reboot #2
« on: June 08, 2015, 04:56:49 pm »
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 *?

Remember the day the walrus started to fly...

I finally cleared my sig after 4 years you're happy now?

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.

Yeah, I see, or any language with integrated graphics :P

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 :P

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.

Spoiler For IMPORTANT NEWS!:
Late last night, Quebec was invaded by a group calling themselves, "Omnimaga". Not much is known about these mysterious people except that they all carried calculators of some kind and they all seemed to converge on one house in particular. Experts estimate that the combined power of their fabled calculators is greater than all the worlds super computers put together. The group seems to be holding out in the home of a certain DJ_O, who the Omnimagians claim to be their founder. Such power has put the world at a standstill with everyone waiting to see what the Omnimagians will do...

Wait... This just in, the Omnimagians have sent the UN a list of demands that must be met or else the world will be "submitted to the wrath of Netham45's Lobster Army". Such demands include >9001 crates of peanuts, sacrificial blue lobsters, and a wide assortment of cherry flavored items. With such computing power stored in the hands of such people, we can only hope these demands are met.

In the wake of these events, we can only ask, Why? Why do these people make these demands, what caused them to gather, and what are their future plans...

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

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?

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 :P

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

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 :P Same thing with the key repeat and also a perceived loophole that wasn't actually there
