[ATC#3] So you say you're a "hacker"? Prove it!

IcyCoder

Let's Play: Figure Out How STINGER works without seeing it in person/seeing the code!

So what we know already:

- Really High Scorer
- It is protected well
- There is some spots in the code that is weak

What we can assume by that:

- Small Code or a lot of IF statements and SET EXECUTION_POINTERs or a mixture of both
- It has some method that protects it from getting TAGed most of the time without taking too much code/time

How can we (I mean I) make a bot to beat STINGER?

- A bot that is small so it can do more so it can get more points
- Creating a fully protected bot that does not take too much code/time

And yes I have a untested prototype that I am working on to do this

you are welcome.

Edit: Please play along

Seriously though, I have no experience to do this kind of thing

I'll note that it's not really fair to show bots off and not actually submit the code. It's no fun when you don't know what weaknesses to exploit.

$(".box-head")[0].textContent = "committing AT crimes since $whenever"

Just put something together quickly and try it

You never know how well a bot will actually do

OK when I am done my testing/fixing I will release the code

Wow I didn't know Snipar could win in a giant brawl!

Right now its main weakness is that it doesn't protect EXECUTION_POINTER so a bot can write malicious code to its unprotected section and then set it's execution pointer to execute it. I'm going to fix this flaw at somepoint.

It uses all 32 lines.

2 IFs, 5 SET EXECUTION_POINTERs.

YOU CAN'T. MUAHAHAHAHAHA

@MATU did you see the problem I'm having with the controller?

STINGER beat Snipar 1v1 119 to 1.

Could you try:
PROTECT EXECUTION_POINTER
MOVE
IF *EXECUTION_POINTER EQUALS -1 1 4
SET *@RANDOM @8
PROTECT @(RANDOM%8+1)
PROTECT @RANDOM
SET EXECUTION_POINTER 1
TAG RunRunProtect

and have another go with the similar
PROTECT EXECUTION_POINTER
MOVE
IF *EXECUTION_POINTER EQUALS -1 1 4
SET *@RANDOM @8
PROTECT @(RANDOM%8+1)
SET @(RANDOM%24+9) @8
SET EXECUTION_POINTER 1
TAG RunRunProtect

Against the first, STINGER won 1v1 25 to 6.
Against the second, STINGER won 1v1 63 to 9.

With some other bots present (using the first quoted RunRunProtect):

Other than possibly SPAMela, I think Snipar has the best chances against STINGER, at least in group scenarios.

jokebookservice1

Well I think mine needs to do more protecting

And way more attacking
And a bit of changing direction

Well it's just not really made for a one-on-one… It has come very close to beating me, though. It's usually higher in points for the first 2000-3000 turns.

Mine needs more protecting and more offense

META-suggestion for the next ATC (regardless of who sponsors it)

Can we
1) do it in Scratch?
and
2) do something whose solution is of long term benefit to the Scratch community?

For example (not a suggestion for the contest, just an example of the sort of thing I mean) solving TSP for max 300 points (cf https://scratch.mit.edu/projects/75405472/ ) - 300 chosen because it fits the clone limit.

There are lots of difficult problems that can find practical applications in games - N-body gravity, billiards, stuff for the NPR studio, …

Oh, alright… but only because you spelled it in all caps.

EDIT: Keep in mind that this is the original code. It wasn't designed to target any specific bot. Please don't specifically target mine.
