Question oIQ seems to decrease 2pts efficiency

Post image
81 Upvotes

I was randomly looking at the code of the game engine (this is part of the index.ts file) this morning to understand a bit better what's happening under the hood.
I then realized that it is the same

p.compositeRating.shootingMidRange

which enters both the probability to take a mid-range, and the probability to make it.
The issue is that oIQ has a negative relation with the "midrange" composite rating:

shootingMidRange: {
ratings: ["oiq", "fg", "stre"],
weights: [-0.5, 1, 0.2],
},

Which is then multiplied with hardcoded values to get the raw chance of making the shot.

probMake = p.compositeRating.shootingMidRange * 0.32 + 0.42

So if I'm not mistaken, oIQ decreases the chance of taking a mid-range (which makes sense), but also decreases the chances of making it (which IMO makes no sense).

Can somebody confirm this?

More generally, if the probability of taking a shot is directly connected to the probability of making it, and if oIQ affects both equally.
Then, additionally to the counterintuitive effect on "midrange" seen above, it also means that players with good oIQ are going to take more "lowPost" shots than "atRim" (because oIQ has proportionally a bigger impact on "lowPost", than on "atRim"). But Layups are a much better shot to take than post shots, because of the existing prefactors in the "probMake" computation.
So you get this weird effect were a high IQ player will actually take less valuable shots.

Again, can somebody confirm I'm not mistaken?

If I'm right, I would suggest the following changes in the code logic:
- make all compositeRating for shooting positively affected by oIQ (I still think IQ should help you make better shots in general).
- add a new compositeRating.shotSelection which is mostly based on oIQ (and maybe Spd and Drb since it gives you more options).
- compute an expectedPointPerPossession for the player (taking into account FT), for each type of shot.
- use compositeRating.shotSelection and expectedPointPerPossession together to stir players shooting tendency towards their best shot.

I fully understand this is probably never going to happen, since it affects some mechanics which are at the core of the game engine. This is also not a critic of the godly work from Dumbmatter. The game is amazing, and I regularly have to force myself to stop playing, so I have time for other games.

Nonetheless, I think it would be a great idea, because it would make IQ behave a bit more like expected. It would also remove some weird behavior which you sometimes observe in game.
It all started with me seeing my 6'4 crazy fast guard deciding to try 2 post move per game for one layup attempt.
I then realized that his speed didn't help with layups (it should IMO), but was increasing the chances of post move. And then I saw that his 80 IQ was even reenforcing this behavior, while making him shot worse at 2pts....

Some side notes from my morning deep dive of the GameSim class, which I also found surprising:
- Blocking chance are the same at the rim and for 3pts.
- "probMake" is affected by the global defense value, for every type of shot: having a good rim protector will have the same defensive impact on post move and 3pts shots.
- Similarly, the chances of taking a shot at the rim or low post increase with offensive synergy and decrease with opponent global defense (not Di). 3pts is not affected by defense at all (and not by Dp).
- Steals are a ratio between Dp and B+Ps after synergies.
- Assists give +2.5% shot chance
- Something which could be a bug: 3pts tendancy uses "shootingThreePointerScaled2" which is lowered for bad 3pts shooters. But "probMake" the probability to make it uses "shootingThreePointerScaled" (no 2 here), which doesn't have the extra decrease for bad shooters. The result is that bad 3pts shooter take fewer 3pts, but shoot them at a higher rate than expected from the shot selection.

Question Other free browser games you play?

41 Upvotes

So, BasketballGM has probably been my most played game of the last several years. It just scratches a certain specific kind of itch for me and I've gotten hours of entertainment out of popping it open and playing for an hour or an afternoon every once in awhile. I'm wondering if there are any other games that other BB GM fans would recommend that are similar?

I've tried some of the other ZenGM management games and they don't really do it for me, partially because I' not as interested in those other sports as I am basketball, and two because I just don't know as much about those sports. But, I'd definitely be interested in hearing game recommendations from other BB GM fans!

If you have any games you'd like to recommend, I'd love if you could tell me about them and why you recommend them!

Question We are developing a new mobile Basketball Manager game (started as a Uni project). Looking for feedback! NO SPAM

Hi everyone!

For the past few months, my team and I have been developing a mobile basketball management game, and we are planning to launch it next month. I’m not here to self-promote, so I’m not going to say the app name!

The Story:
It actually started as a university project, but once we finished the prototype, we realized something: while there are tons of great football/soccer manager games on mobile that offer a balanced experience, the basketball market seems to lack a game that is deep but not overly complicated (idk why!) . So, we decided to keep working on it.

We need your help:
We are close to release, but we really value the opinion of basketball fans.

  • What is a "must-have" feature for you in a mobile manager game?
  • What is something you absolutely hate seeing in these types of games?
  • Any feedback on the UI based on the screenshots?

Current State:
Right now, the game focuses on the NBA. However, we are already planning to add international leagues (EuroLeague, domestic leagues, etc.) in future updates.

Thanks to anyone who takes the time to comment or give us some tips!

This guy was an absolute monster defensively but sucked offensively, but the fact that awards I don't believe are accounted for in the HoF calculations. Honestly the HoF and jersey retirement formulas need to be completely reworked, cause guys that were 3x all stars and played 10+ years on good teams make the HoF, but not... this guy.

Question Some simple fixes would make this way more enjoyable

0 Upvotes

Just a quick rundown:

1) Why are the rookie contracts so short? If you can't create a restricted FA system, then maybe make the rookie contract 5 years?

2) I get that " insane" is supposed to be...well, insane, but what is ACTUALLY insane (and not in a good way) is how shitty your players become. Draft a dude with a 74 potential? He'll be shit in three years. Obviously, this happens in real life, but the rate in which guys with high potential apparently forget to play basketball is not fun. Any meaningful FA signing you make will be negated by them completely regressing.

3) Injuries happen...but the rate in which they happen in the playoffs is absurd. I don't know if I've ever made a full playoff run without at least one all-star turning an ankle. That's the other thing too...the injuries are often so fucking supid. Patellar Tendinitis is not a diagnosis that happens at he rate this game seems to think it does. Who is missing a playoff game with a bruised back? The amount of potential titles I've missed out on because of sprained toes...

4) Contract extensions. Why is that not a thing either? Can't be that hard.

5) One bad year and everyone stops going to games? I live in Chicago. The Bulls have been shit, and it's still packed there.

Will continue to hate play, but some of this shit seems so fixable and continues to be so annoying.

Question Are Shaq's ratings kinda low for the player he was?

I don't know shit about basketball, I just play this game and know really vaguely the greats of history, but the way people talk about Shaq, he was like an 80 in his (short) prime and at least a 70 for a lot of it, no? Yeah I heard he was washed near the end but his Magic/Lakers days never broke even 70?

Can anyone help me out? Maybe his literal talent wasn't elite but his physicals were just so dominant and the game's rating system just isn't built for translating a player like Shaq?

Question Is there a way to implement an Academy system rather than a Draft?

16 Upvotes

I'm currently creating a fictional British Basketball League. In the UK, teams offer young players pathways through their academies rather than a draft, so I'm wondering if there was a way to emulate that in the game.

Ideally, a system whereby two rookies would be randomly generated for every team at the end of each season would be the best solution, so I was just wondering whether this was possible. If not, then I think it would be a neat possible feature for the future for people making leagues in countries that don't use a draft system.

Question Is there any interest in advancing the college basketball GM game?

I admit I am more obsessed with college basketball than NBA, which has caused most of my saves to fizzle out when players I no longer recognize dominate the scene, as I care for players, not any specific teams. I have perused the archives in this subreddit and have seen dumbmatter's inclinations that he is interested in rejuvenating the college basketball game, but I haven't seen any word on him starting on that. In light of that wonderful sport just around the corner, is anyone here likewise interested in him resurrecting this game?

Question Im so lost

3 Upvotes

Hey everyone, I'm feeling pretty lost with a lot of the mechanics in this game. I'm definitely not saying the game is bad, but my usual trial-and-error process for figuring out management games just isn't working here. I figured I'd list what I did in my first few saves and what I'm still struggling to understand:

1.​For my first league, I picked the biggest market team so I could experiment with trades, contracts, and player development without getting fired immediately. The 'problem' was that my team randomly generated a 23-year-old PF with 75 OVR and 80 POT. So yeah, I basically started with the GOAT.

​Because of that player, I got completely carried to 3 rings (mostly by just abusing Free Agency like a madman to build around him). At the time, I actually thought I had mastered the game, but looking back, I realize I learned absolutely nothing.

2.​I had no idea how to draft. At first, I tried to land a good player (since I got a lottery pick in my first season), but I didn't understand any of the parameters to measure potential or how to tell if a prospect would actually turn out good. I basically just looked at height, basketball IQ, and searched for specific "types" of players, but it never worked out for me.

3.​Player development is what I understand the least; it feels completely random to me right now. I've had players who grew steadily for three years, only to suddenly lose their potential or even drop in overall rating the very next season for no apparent reason. I've tried everything: increasing minutes for talented young guys, reducing their role if they underperform, you name it. But these random regressions seem to happen to players of all ages. I even got to the point where I assumed it was a realism feature—like they got lazy after securing their second contract, or they stopped developing because there was no competition for their starting spot!

​I think these two mechanics (drafting and development) are the main things keeping me from really enjoying the game. I know it's definitely a skill issue on my end, but if I could just wrap my head around them, I'd finally be able to focus on the deeper aspects like the economy and cap management.

4.​Still completely lost, I kept trying to figure things out in new saves (playing with smaller markets), but I just kept experimenting and failing miserably. I tried looking for guides on YouTube, but there's basically nothing out there.

​I will gladly accept any guide, tips, or advice from veteran players. I really want to understand the game so I can properly enjoy it. I wouldn't normally resort to asking like this, but I'm genuinely struggling to grasp the mechanics even after multiple saves. Thanks in advance!
