The Mental Game

Postby Guest » 03 Feb 2006, 04:35

Tell me if I am being completely stupid, but is there a sort of "mental game"? Often it seems that the computer will start missing more frequently after losing alot of points, or even I start missing. This is especially apparent for my serve. After I fault more often or am losing, I fault much more, even though I am doing the exact same thing. So is there some sort of mental toughness? If so...how in the world did you (or would you) do that?!

Hello,

I could tell you, but as it's very simple, it would break the magic ! ;)

Ahh so it isn't just my imagination! They probably just get worse when they mess up or lose 8) (if its that simple). Could this please be editable in the next update? Talk about making the game realistic, if this were editable... :shock: .

P.S.: In a file I saw something about "soul" and "stress" (must have somethign to do with it). Could you please e-mail me about how it works? Trust me, since I am the owner of a tennis forum, your game will no doubt be advertised too. My address is jglagjglag(at)yahoo-com

It's so simple that it's actually not editable, it's a consequence of the way I built the AI.

"Soul" can be "human" or "CPU", so nothing special behind it... ;)
"Stress..." is used for the match simulations between 2 CPU players.

Ok, so what are soul and stress, specifically? What would editing them do? Do they have an imapact on playing?

"soul = 0" (or 1) means this player is controlled by human, and "soul = 2" (or 3) means this player is controlled by computer.

About stress, and other stuff for match simulations, here the parameters :
Code: Select all
[WT_ScoreSimu]
StressMinDiff   =   1000
StressLowering   =   1.0   // difference *= StressLowering
StressPow   =   5   // difference *= Pow(random[0, 1], StressPow)
            //===> Higher Skill -= difference
FormLowering   =   0.4   // ratio = FormLowering
FormPow      =   6   // ratio *= Pow(random[0, 1], FormPow)
            //===> Skill *= 1 - ratio


All of these parameters only apply in the match simulation, done to create scores in the draw of tournaments.
If you actually play a match with your player, these parameters aren't used.

"FormLowering" is the maximal coefficient of strength loss, to simulate the form of the day.
At 0.4, it lowers the player strength at a maximum of 40%.
This coefficient is multiplied per a random number between 0 and 1, modified by "FormPow".
The more “FormPow” is big, the more the maximum form lowering will be rare. The more it’s small, the more the maximum form lowering will be frequent.
Both players have their own form of the day.
These 2 parameters are the ones that really raise the chances of good players to lose against players weaker than them.

"StressPow" is there to simulate the stress of the strongest player. Only the strongest player is affected.
His strength is lowered to get closer of the weakest player.
The more “StressPow” is big, the more rare the strongest player will be at the level of the weakest one. The more it’s small, the more often the strongest player will be at the level of the weakest one.
This parameter help to have more balanced matches, sometimes, between 1 very good player and 1 very weak player.
But it also makes closer 2 players already close, so “StressMinDiff” is used to cancel the stress when 2 players are close enough.

I hope it's understandable ... I'm afraid my English skills show their limit... :roll:

No your english was fine, and I believe I understand what it means now. How can these be edited for each player though? (By the way you should encorporate form lowering into human/cpu matches too).

in TE2005, it's not possible, but in TE2006, it's already done ;)
you could add these parameters for each player, in the Players.ini :
- Inconstancy (equivalent of FormLowering)
- InconstPow ( = FormPow)
- Stress ( = StressLowering)
- StressPow

That's great. Just to clarify (not because your English is bad but because my brain capacity for this kind of stuff is low. :wink: Your English is excellent by the way. Much better than my French, that's for sure), if I want to minimize the number of upsets that happen in tournaments what I would do is I would raise FormLowering to a higher number (like 0.9 for example) and Form Pow (to something like 8 or 9) and I would raise StressPow to a higher number (like 8 or 9)? Correct?

And just for theory's sake to make sure I understand, if I were to raise FormLowering to 1.0, Form Pow to 10 and StressPow to 10, upsets would never happen. Right?


Also, if you change these parameters in the middle of a tour, do they still take effect in that tour?

Thanks a lot in advance.

If you want to lower the upset frequency, but still have some upsets, just put this :
StressPow = 15
FormPow = 15

If you want to completely turn off the increase of the upsets, put this :
FormLowering = 0
StressLowering = 0

But even so, it'll have still some upsets from time to time, but they should be quite rare...

Let the game runs 1 year with the new setting, and check the results in the Grand Slam events to see how it turns out.

sometimes i think the computer figures out my tactics and they change their game to stop me using it.
