Post Understanding slider coefficients

This is for all slider makers, roster makers and for general 2k knowledge.

- Slider effects show in-game (substitution menu) during gameplay.

How to check:
Start game, right after tip pause, go into substitution menu, note ratings, go to sliders, change an attribute slider, go back to game, let run 1-2 seconds, pause again, go to subs again, note change in rating.

Now with this 'new' knowledge we can do mass edits to the roster through slider attribute edits instead of going through all of the players and editing individually.

So far, after some initial testing, each slider has its own coefficient variable. Meaning that each slider changes said rating different than all other sliders.

For example; Shannon Browns 2k default dunk rating is 89, with the dunk attribute slider at 50, in game his rating is an obvious 89.

But once you change the dunk attribute slider in any direction and go into the sub menu, you will see that the rating changes. 2k shows this with red and green arrows.

Also take into account that fatigue from gameplay also changes ratings during game (real time). Same goes for the hot/cold streak system too.

I will post some observations further down on the slider coefficients.

BIG side note/tangent:
Difficulty level (Pro, All Star, SS, HoF) rating changes can be seen too in the sub menu as well. Meaning, it shows how much the CPU is boosted when you change off of Pro level.

Test: Scrimmage mode (no fatigue).

Pro level. Tip off, pause. Check ratings, no deviation (no arrows either direction). Go to controller, switch teams, check ratings, again no deviation. Note Jermaine Oneals standing dunk rating = 62.

Change difficulty to All Star, start scrimmage for 2 seconds. Pause game, switch off of Phoenix to OKC. Start game, pause. Switch back to PHO, check sub menu. Note JO standing dunk rating (green arrow now) = 67. Switch off PHO, change diff to Superstar. Start scrimmage for a sec. Pause, switch back to PHO. Check sub menu, JO standing dunk now a 70. HoF = 72.

So with that here are the results from that test.
Jermaine Oneal default 2k standing dunk rating = 62
Pro level (CPU) = 62
AS level (CPU) = 67
SS (CPU) = 70
HoF (CPU) = 72

So without a shadow of a doubt, the CPU is boosted on any other level than Pro.


With that, here are the boosts the CPU gets:

Standing Dunk rating
Pro = -2
AS = +5
SS = +7
HoF = +10

Block Rating (JO again) default rating 80, note this boost is only for CPU, HUM does not get it.
Pro = 78
AS = 85
SS = 88
HoF = 92

So we can see that indeed, it does make the game more difficult only because its increasing the CPU player ratings tremendously. Therefore making the game worse in my opinion, as it makes alot of the players have the same ratings, due to 99 being the top and 35 being the low.

Best bet is to keep the sliders within 40-60 range, occasionally going over/under.

Note: Ballhandling attribute effects (Ball handle rating and Ball Security rating, not OFF HAND DRIBBLING = BOOO 2k) So keep in mind that editing this slider will lower/raise handles and security but off hand dribbling will remain the same (cannot be changed with sliders).

Below is a list of attributes that the CPU alters with the difficulty changes:

Dunk
Ball Sec
Handles
Block
Steal
Both REBs
Both AWRs
Strength
Vert
SOD and SIT
Quickness
Hustle
Hands
On Ball Def
Standing Dunk


Okay some slider coefficient observations, Shannon Brown default dunk rating by 2k = 89.

At 50 dunk att slider he is a 89 in game sub menu.

Now the coefficient column shows how much each click at that slider # represents. As you can see, it looks like they tried to keep it around 1.5 per click.

Continuing...

Speed Att Slider - Shannon Brown default 2k rating = 90.

Again 1.5 seems to be the target range.

Note: The CPU difficulty boost does get added on-top of slider adjustments.

Will continue to add to this thread with future observations. Thanks for reading.


NBA2K13 Rating changes per difficulty and how to adjust sliders accordingly

What's up everyone, here are the exact rating changes that 2K makes whenever you change the difficulty so that you can adjust the sliders to counter the CPU cheese and have a more balanced game. Sneaky 2K makes some changes you may not expect...

The number given after the attribute is how many slider points you must add to or subtract from the CPU to make the players balanced. IF there is a + before the number it means you add to the CPU slider, a - means you subtract from CPU slider.


BIG UPS TO SAVANTOPUS FOR WHATS BELOW!

PRO:
Def and Off Awareness +2
Hands +2
Ball Security +2
Def and Off Rebounds +2
All other Attributes +1 (except for steal, pass, stamina, durability, fatigue, consistency)


ALL STAR:
Def and Off Awareness -10
Hands -7
Ball Security -7 (tricky because you can only change this through the Ball Handling slider which changes 3 different attribues, Ball Security, Off-hand dribbling and Ball Handling... I use Roster Editor by LEFTOS to change this independently)
All other attributes -3 (except for stamina, durability, fatigue, consistency)
Offensive scoring sliders +4. Yes, add 4 to the CPU scoring sliders to get a shooting percentage balance. Inside scoring, close, mid, 3pt. Offensive scoring slider is subjective and based on my personal playing experience.

SUPERSTAR:
Def and Off Awareness -17
Hands -14
Ball Security -14 (tricky because you can only change this through the Ball Handling slider which changes 3 different attributes, Ball Security, Off-hand dribbling and Ball Handling... I use Roster Editor by LEFTOS to change this independently)
Steal -7
Def and Off Rebound -7
All other attributes -6 (except for stamina, durability, fatigue, consistency)
Offensive scoring sliders for Superstar seem like they are already balanced; need to subtract or add from USER or CPU, keep them the same as each other.

Hall of Fame
Def and Off Awareness -20
Hands -20
Ball Security -20 (tricky because you can only change this through the Ball Handling slider which changes 3 different attribues, Ball Security, Off-hand dribbling and Ball Handling... I use Roster Editor by LEFTOS to change this independently)
Steal -10
Def and Off Reb -10
Dunk ability -7
Speed -7
All other attributes -8 (except for stamina, durability, fatigue, consistency)
Offensive scoring sliders for Hall of Fame I do not know because I don't play on this difficulty, I play Superstar.

Cheers, Mates
