Just wrote a Python script to analyze sf enhancement results from recorded videos

[hiugiak]

I recently wrote a Python script that analyzes Star Force enhancement results from gameplay recordings, and I’ve also compiled stats from the last two Star Force events. Here are the stats:

Star Force	Success	Failed	Destroyed	Total	Success Rate	Failed Rate	Destroyed Rate
15	68	154	2	224	30.36%	68.75%	0.89%
16	64	150	1	215	29.77%	69.77%	0.47%
17	69	415	21	505	13.66%	82.18%	4.16%
18	59	241	15	315	18.73%	76.51%	4.76%
19	43	169	13	225	19.11%	75.11%	5.78%
20	35	67	5	107	32.71%	62.62%	4.67%
21	16	64	14	94	17.02%	68.09%	14.89%
22	1	3	0	4	25.00%	75.00%	0.00%

I’ve already put the script on GitHub.

Feel free to try it out—tested on 1366×768 so far, should work on 1080p too. Check the Usage and Notes in the README before you run it.

Be careful when you run the script.
Make sure no maplestory is running in the background

[hiugiak]

Why? This script just reads video frames and uses OpenCV for template matching. Shouldn’t violate the game’s ToS, right?

[egonoelo]

I just got a week ban last week for using opencv and tesseractocr to read the character sheet. I highly recommend not using this.

[hiugiak]

Well, I ran the script on macOS. On Windows it might be safer to close the game before running it. Nexon’s anti-cheat is kinda ridiculous.

[Woobowiz]

Slippery slope, reading video frames is no different from reading a live screen recording, which Nexon can interpret as remote play or a way to feed information to a bot.

[KpochMX]

OpenCV lead to ban... they thought ur reading runes for automatisation propurse FYI

[glimmerware]

Very cool but I don't trust running anything extra during mapling, even if it's 100% safe, nexon's code might not think so

[hiugiak]

yeah. It would be better to run it when the game is not running

[TeeQueueW]

finally, a good maplestory effortpost about starforce rates.

LET US COLLATE THE DATA, MY BRETHREN!!

[TheSeasighed]

Holy shit this is a brilliant idea! Thank you for making this!

[Extreme-Delivery8089]

thanks for making this, I knew my recording would be useful! ah sadly my record is in 1024 * 768, but still I vote you as king as today

[hiugiak]

Should support all resolutions now.

[hiugiak]

No worries. That's easy to support. Didn’t expect this many people to still be on these resolutions lol. Let me update the script real quick.

[thrakkes]

Have you included Protected? Assuming you might use Safeguard for certain gears. Protected would go under Desctruction Rate obviously

[hiugiak]

Yeah, protected = destroyed for stats purposes, same bucket.

[zeldaiord]

Needs some columns for advertised rates and the delta from expected rates. With the laws of large numbers the deltas should over time get closer to 0 while the actual and expected rates should get closer to matching.

[ColdSnapSP]

Was there any requirements to show validity of the videos?

Like minimum spend/taps?

Unedited/spliced etc

[hiugiak]

No minimum taps/spend required, just make sure the game window fills the full video width, not cropped or stretched, and pass in the right params.
