Does anyone have any methods for determining what a custom ship's score should be?

What does transdata use to compute scores?

It's not a very sophisticated algorithm, and it could certainly use some help:

Code: Select all

int CShipClass::ComputeScore (const CDeviceDescList &Devices,
							  int iArmorLevel,
							  int iPrimaryWeapon,
							  int iSpeed,
							  int iThrust,
							  int iManeuver,
							  bool bPrimaryIsLauncher)

//	ComputeScore
//
//	Compute the score of the class based on equipment

	{
	int i;
	int iSpecial = 0;
	int iExceptional = 0;
	int iDrawback = 0;
	int iStdLevel = iArmorLevel;
	int iWeaponLevel = (iPrimaryWeapon == -1 ? 0 : ComputeDeviceLevel(Devices.GetDeviceDesc(iPrimaryWeapon)));

	//	If our weapon is better than our armor then adjust the level
	//	depending on the difference.

	if (iWeaponLevel > iArmorLevel)
		{
		switch (iWeaponLevel - iArmorLevel)
			{
			case 1:
				iStdLevel = iWeaponLevel;
				iDrawback++;
				break;

			case 3:
				iStdLevel = iWeaponLevel - 2;
				iSpecial += 2;
				break;

			default:
				iStdLevel = (iWeaponLevel + iArmorLevel) / 2;
			}
		}

	//	If our best weapon is 2 or more levels below our standard
	//	level then take drawbacks exponentially.

	if (iStdLevel > iWeaponLevel + 1)
		iDrawback += min(16, (1 << (iStdLevel - (iWeaponLevel + 2))));
	else if (iStdLevel > iWeaponLevel)
		iDrawback++;

	//	If all movement stats are high then this counts as an
	//	exceptional ability

	if (iSpeed == enumHigh && iThrust == enumHigh && iManeuver == enumHigh)
		iExceptional++;

	//	Otherwise, treat them as special abilities or drawbacks

	else
		{
		if (iSpeed == enumLow)
			iDrawback++;
		else if (iSpeed == enumHigh)
			iSpecial++;

		if (iThrust == enumLow)
			iDrawback++;
		else if (iThrust == enumHigh)
			iSpecial++;

		if (iManeuver == enumLow)
			iDrawback++;
		else if (iManeuver == enumHigh)
			iSpecial++;
		}

	//	1 armor segment is a drawback

	int iArmorSections = GetHullSectionCount();
	if (iArmorSections <= 1)
		iDrawback++;

	//	2-3 armor segments is normal

	else if (iArmorSections < 4)
		;

	//	4 or more armor segments is special

	else if (iArmorSections < 8 )
		iSpecial++;
	else if (iArmorSections < 16)
		iSpecial += 2;
	else if (iArmorSections < 32)
		iSpecial += 3;
	else if (iArmorSections < 64)
		iSpecial += 4;
	else
		iSpecial += 5;

	//	Checkout all the devices

	bool bDirectionalBonus = false;
	bool bGoodSecondary = false;
	int iDirectionalBonus = 0;
	for (i = 0; i < Devices.GetCount(); i++)
		{
		const SDeviceDesc &Dev = Devices.GetDeviceDesc(i);
		CDeviceClass *pDevice = Dev.Item.GetType()->GetDeviceClass();
		int iDeviceLevel = ComputeDeviceLevel(Dev);

		//	Specific devices

		switch (pDevice->GetCategory())
			{
			case itemcatWeapon:
			case itemcatLauncher:
				{
				int iWeaponAdj = (iDeviceLevel - iStdLevel);

				//	If this is a secondary weapon, then add it to the score

				if (i != iPrimaryWeapon)
					{
					//	Calculate any potential bonus based on the weapon level
					//	compared to the base level

					iSpecial += max(iWeaponAdj + 3, 0);
					}

				//	Compute fire arc

				int iFireArc = (Dev.bOmnidirectional ? 360 : AngleRange(Dev.iMinFireArc, Dev.iMaxFireArc));

				//	Adjust for turret-mount

				iDirectionalBonus += (max(iWeaponAdj + 3, 0) * iFireArc);
				break;
				}

			case itemcatReactor:
				//	Reactors don't count as improvements
				break;

			default:
				{
				//	Other devices are special abilities depending on level

				if (iDeviceLevel > iStdLevel+1)
					iExceptional++;
				else if (iDeviceLevel > iStdLevel)
					iSpecial += 4;
				else if (iDeviceLevel >= iStdLevel-1)
					iSpecial += 2;
				else
					iSpecial++;
				}
			}
		}

	//	If we have no weapons then we have some drawbacks

	if (iPrimaryWeapon == -1)
		iDrawback += 3;

	//	Add bonus if weapon is omnidirectional

	iSpecial += (int)((iDirectionalBonus / 270.0) + 0.5);

	//	Checkout AI settings

	const SAISettings &AI = GetAISettings();
	int iFireAccuracyScore, iFireRateScore;

	if (AI.iFireAccuracy > 97)
		iFireAccuracyScore = 5;
	else if (AI.iFireAccuracy >= 93)
		iFireAccuracyScore = 4;
	else if (AI.iFireAccuracy >= 90)
		iFireAccuracyScore = 3;
	else if (AI.iFireAccuracy < 75)
		iFireAccuracyScore = 1;
	else
		iFireAccuracyScore = 2;

	if (AI.iFireRateAdj <= 10)
		iFireRateScore = 5;
	else if (AI.iFireRateAdj <= 20)
		iFireRateScore = 4;
	else if (AI.iFireRateAdj <= 30)
		iFireRateScore = 3;
	else if (AI.iFireRateAdj >= 60)
		iFireRateScore = 1;
	else
		iFireRateScore = 2;

	int iFireControlScore = iFireRateScore * iFireAccuracyScore;
	if (iFireControlScore >= 20)
		iExceptional++;
	else if (iFireControlScore > 6)
		iSpecial += ((iFireControlScore - 5) / 2);
	else if (iFireControlScore < 2)
		iDrawback += 4;
	else if (iFireControlScore < 4)
		iDrawback += 2;

	//	Compute final score

	ScoreDesc *pBase = &g_XP[iStdLevel-1];
	int iScore = pBase->iBaseXP
			+ iSpecial * pBase->iSpecialXP
			+ iExceptional * pBase->iExceptionalXP
			+ iDrawback * pBase->iDrawbackXP;

	return iScore;
	}
Note: Probably best if you copy the above to a real editor (or Notepad) for better readability.

Thanks george!
I'll need to put this on the wiki later...

Slapping that into a batch file and running it causes a crash, so I'm assuming I need to replace those arguments with something else? But I'm not sure what.

Try downloading TransData 1.7:

http://www.neurohack.com/downloads/TransData17.zip

Perhaps the old version (1.6) is not compatible with RC2

Okay that works.

So what's the difference between the score and the score in parenthesis?

The score in parenthesis is the score that is listed under score= in the <ShipClass> element.

Sometimes it helps to override the computed score (but in practice, I think the computed score is better than my subjective score)

Does that mean if we don't define any score= in the ship class, then the game will compute its own score?

I tried using Transdata 1.7 with RC4 to generate a score list, but I can't get it to work:
C:\temp\Trans10RC4>transdata /shiptable /score
TransData v1.7

Hmmm..I don't know - I get the same error. Hold on, I'll attach an screenshot

It's a clean install using RC4 and transdata 1.7
