DFalcon -> Air Combat Mod with test results (11/14/2005 7:10:42 AM)

Hello,

It has been suggested that air combat in the game is too deadly. Planes are lost quickly and airbases closed in only a few raids. Many battles are lopsided when superior aircraft are involved.

I gave some thought to how the data base could be modified to address these issues and read most of the threads and ideas posted on the boards. I began to tinker with the editor and test the changes I made to the data base. I wanted to make a change that was simple and to have the effect subtle, as I think the game over all works very well and did not want the changes to teeter things over the edge.

I think I have a working modification that addresses the above issues. I am going to be doing extensive test on it now. I wanted to share my ideas and the tests with others playing the game.

The details of my modifications are as follows;

I reduced the firepower of all air to air cannons by 25%. I did this by reducing the effect rating by one point. Where this reduced the firepower by more than 25% accuracy was increased proportionally to compensate.

I softened the differences in speed and maneuverability between fighter aircraft. A median point of 340mph and 33mvr was chosen and the difference from this median was halved. Speed was always rounded up. Maneuver was rounded up if the value was above the median and down if it was below.

The standard payload of level bombers was reduced by 25%. Fractions were always rounded up.

These simple changes seem so far to produce the effect I was looking for in my preliminary test and will start running more comprehensive tests and will post the results here.

To conduct these tests I have created a custom scenario in the Solomons with two Japanese airbases at Rabaul and Lea and two US airbases at Port Moresby and Torokina. I placed base forces and aviation support at the bases leveled the experience and leaders for all of them.

I have placed a group of fighters and a group of bombers at each base. The experience and leaders have all been set to the same values for all the air groups.

I will set up battles between the opposing airbases and run them five times each with the modified data and the stock data. This will give me ten results for each match up.

I will start with a classic match up, the A6M2 on CAP vs. attacking Dauntless escorted by F4F-4. I will post results when they are complete.

I welcome your comments and suggestions.

Test Result #1

Day Air attack on Rabaul , at 61,88

Japanese aircraft
A6M2 Zero x 57

Allied aircraft
F4F-4 Wildcat x 33
SBD Dauntless x 57

Japanese aircraft losses
A6M2 Zero: 7 destroyed, 3 damaged
D3A Val: 4 destroyed

Allied aircraft losses
F4F-4 Wildcat: 6 destroyed, 3 damaged
SBD Dauntless: 8 destroyed, 22 damaged

Airbase hits 1
Runway hits 14

I ran this type of battle 10 times with the following settings;

Defenders
72 A6M2 80% Cap
72 D3A targets

Attackers
36 F4F-4 10% Escort
72 Dauntless

DF,

Maybe a reason for the F4F doing better is that you adjusted the Zeke because it had 2 x 20mm but not the F4F because it had 6 (or 4) .50cal,



Sardaukar -> RE: Air Combat Mod with test results (11/14/2005 1:54:22 PM)

By the way, you could also test with reduced weapon accuracy. I've planned to do that for some time, but haven't had time so far.

Why is that a problem? A base COULD BE closed in a few raids - or even in a single raid - IF you hit it hard enough and accurately enough.

I have seen data indicating that very large air combats may be producing too many air to air kills. I have never seen any data indicating a base is too hard to close. In fact, the reverse, I find it hard to KEEP a base closed IF it has engineers and supply.

This is a bad concept in principle. It imposes two requirements on everyone involved - forever - in designing planes -

a) they must know and understand this change
b) they must do still another calculation.

Better by far to take something that is a strait data input from reality and preserve it. Of course, ideally, we could modify what code does with that data. In this case, we can't do that. So it becomes possible we might want to manipulate the data in this way. But it should be a LAST resort, not a first pass.



el cid again -> RE: Air Combat Mod with test results (11/14/2005 2:08:33 PM)

Most of your ideas seem UNRELATED to your stated goal - that is they affect AIR TO AIR combat, not AIR TO GROUND combat. In fact, REDUCING figher effectiveness may INCREASE the ease of shutting down bases - since fighters can DEFEND bases!

The idea of reducing bomb load is a problem - because bomb load (and other weapons loads) are dirctly related to range. Are you going to reduce torpedo and missile values too? And did you consider that reducing the load will mean a plane CANNOT carry a special weapon it REALLY CAN carry? Did you consider that the RELATIVE range penalty for carrying bombs to torpedoes (other devices) will shift, and incorrectly so?

Now if you wish to reduce ACCURACY for BOMBS, that is a different thing. But note you will impact NAVAL as well as LAND combat when you do so. Are you SURE you want to do that in a NAVAL game where careful work went into getting quite good results in naval bomb strikes?

IF you really want to reduce AIR TO AIR fighter values - honor the manual and rerate planes in knots vice mph. Then run your tests.

There are fundamental problems with the way WitP deals with air combat and air attacks that no amount of tweaking will resolve. I believe the unrealistic results stem from:

* CAP being able to intercept every raid thrown at a target, with no detriment for dealing with multiple raids, or distance to target hex.
* Bomber and escort aircraft squadrons being able to combine irrespective of launching base location or command structure.
* Target bases being treated as a single airfield when they could be many. Using the WitP game scale a single hex would represent SE England in the Battle of Britain with Germany having several for parts of Europe. Although Germany could send large raids totalling many hundreds of aircraft, they could not all be intercepted by every fighter available. Nor could a few day’s raids put every airfield out of action. I believe this point is equally applicable to the shore bombardment effect on airfields.

It's tricky and difficult to balance the air-to-air combat so that air-to-ground combat doesn't get too effective. It's relative easy to change weapons, durability etc. to reduce air losses, but difficult to judge if it gets too easy to bomb places, ships and units to pieces with impunity.

All guns were reduced. The 20mm went from 4-22 to 3-22, the 50 cal from 3-29 to 2-33.

The way I did the reduction was to to multiply the effect by the accuracy, then reduce by 25% and divide by the new lowered effect.

If this Mod does not test out well I may try that solution.

I agree this is not a major issue. A reason for this adjustment also has to do with some early testing I did. With reduced firepower more bombers were getting to drop bombs and I wanted to off set this some what.

Early tests indicated the change was slight, testing will tell.

If I could change the code I would. I do not even know what the code factors in outside of my observations. I can work with the data and if the results are good how I got them does not bother me too much.

My early test showed that reducing the load value had no effect on the number of hits scored on a base. It also showed it had no effect on what ordinance an aircraft would carry. I suspect it is only used when flying extended range, but I have not tested this. Because I saw no results and it was tied to so many other aspects, like what base could support heavy bombers and extended range load out, I did not change this value. Too mant interactions not enough information.

In my testing I discoverd changing the standard pay load had a small effect. Hopefully enough to counter the problem you addressed of more bombers making it on target.

I would also like to stress that the changes I made initially showed very small differences in initial testing. The effect was subtle and this is what I was looking for. That is why I started doing more in depth testing.

I was excited enough to share the information.




Sardaukar -> RE: Air Combat Mod with test results (11/14/2005 4:10:12 PM)

Ordnance listed is used only against ships. Payload is used against land targets, be it installations or units, IIRC.

Nothing is perfect and this game is no exception. I still think it is great. I just thought a tweek would be nice and wondered if I could make one that made a small change with out breaking the thing.

Yep, but that is why I wanted to test.

BTW, I can send any one interested the Mod and the test scenarios if they are interested.

That is what I thought. In my tests it did not work out that way. The only time I was able to notice an effect on the number of hits was when I reduced the standard payload. To get a noticable and consistent change I had to reduce a B-17 from 12 boms down to 1.

Part of the issue is the wide variety of results the combat system will generate from near identical match ups. Given this spread of results I am concerned that 10 test will not be a very accurate test of any particular match up. But after doing 8 or 10 such match ups and getting 80-100 test battles I can see what the trend is.



Sardaukar -> RE: Air Combat Mod with test results (11/14/2005 4:23:39 PM)

You mean you did reduce the "Max load" number and it didn't reduce the hits ?

Yea, I reduced a B-17 from 6800 max load to 680 max load and it had no noticable effect. I should mention that all my tests were conducted at a 4 hex range, well with in normal range for the B-17. So I suspect that Max laod is only used to determine what the load out will be when subtituting weapons at extended range, for air base requirements, and for transport.

I suspected something about Max load when I noticed that there are US torpedo bombers with a Max load below the load of their torpedo and it did not effect them.



Sardaukar -> RE: Air Combat Mod with test results (11/14/2005 5:04:00 PM)

Weird !! Well, so much about reducing effects of bombing by that.

My reaction exactly! It may be a blessing in disguise though. With Max load tied to air base restrictions I was very reluctant to change it. Also with a reduction for extended range it might have made planes too ineffective. I think it may work out better this way.



Sardaukar -> RE: Air Combat Mod with test results (11/14/2005 5:52:47 PM)

You may well be right with that. Airbase limitation is important factor in game.

This is quite untrue. One of the best strategies in UV or WITP is to throw multiple strikes at the same base. After a while, the CAP gets tired, and it gets less numerous (although the SECOND wave of CAP is usually STRONGER in numbers). The model clearly DOES consider tired pilots, and maintenance issues, and after 3-5 strikes, NO raid will be intercepted at all, as a rule.

While bombers and escorts CAN combine, they USUALLY do NOT do so. They do this better when in range of an appropriate air HQ. I regard this as realistic and historical. Mostly, bombers attack a base in range order - that is the short range strikes come in first - the long range strikes later. This has always been true, in all mods, going back to UV 1.0.

This was not always so. You can see remnants of the earlier idea in the code - e.g. the "all bases in this hex" button. But you are confused about what they did do: the base situation is abstracted - which is not to say they all are a single base. Rabaul had two airfields BEFORE the war began, and Japan built more "in the same hex." One reason it is harder to take out a higher level airfield is that it represents more than one runway.

This does not mean the concept could not be improved. I would like to see damage reduce the airfield level - rather than take it all down as soon as it goes over 50%. At some point your level 5 airfield becomes a level 4 airfield - etc - until you fix it.

Unless you work in isolation, this may be short sighted? Some poor guy comes along after you and does not know what you did, he puts in his plane with correct data - and it is now unbalanced relative to others in the game. Better to keep it simple and obvious how to create a unit - if you can.

What you seemed to say was that you reduced the bomb capacity by 25%. That WOULD prevent a plane from carrying a torpedo or OHKA or whatever most of the time. IF instead you changed NORMAL bomb load, that is not a problem at all. Sometimes normal bomb loads were too high in fact.

Plain false. See my Ohka test thread. Clearly ordnance listed can be used against land targets. Further, clearly if the plane cannot lift the ordnance, it won't, even if it is listed as an option. IF you reduce payload to below the weight of a torpedo, you cannot lift it, and the AI won't.
