Did someone post a link to a javascript RaceWizard? I seem to remember seeing it mentioned, but I can't find it in my searches of the forum.

Anyone have a copy of it?



Come see my Stars! clone, CraigStars!

Were you thinking of this one: http://home20.inet.tele.dk/craebild/hab_range_tool/habcalc.h tml


Have fun.

I saw that one and it's pretty deluxe. I thought there was one that calculated the points for a race ala the race wizard. I can do it on the server side but I thought it would lend to a better user experience to have that calculation done client side as well.

If you have the formulas for calculating the points, then it isn't impossible that I or m.a@stars can add point calculations to the hab and econ calculator.

There are formula's in the freestars source code:

http://freestars.svn.sourceforge.net/viewvc/freestars/trunk/ Server/Race.cpp?revision=14

It's not too tricky to follow until it gets to the part about calculating the Hab points by generating a bunch of planets. I haven't read that enough to fully understand it but the points calculations are probably fairly accurate. LEit and the freestars guys are highly dedicated to accuracy.

That would be in C++, not Javascript. Still, AFAIK the logic and math commands are the same in C++ and Javascript, so the fact that I do not know C++ should not be a major obstacle.

You mention "calculating a bunch of planets". The code for the hab and econ calculator contains code for calculating the theoretical spread, i.e. the equivalent of averaging an infinite number of random planets.

If Stars! uses a sufficiently low number of planets, then that means that creating the same race twice could give different point totals in Stars!. I would suggest using the theoretical spread for any Stars! clone instead of a limited number of random planets. In my opinion, there is no need to reproduce the bugs in Stars! in a Stars! clone.

I haven't taken a look at the code you linked to yet, but I will - It might not be today, though.

Actually, I already did. It's not complete, though... Whip

If that code is there then they must have used the reverse engineered code that surfaced a couple years ago. Nobody understands it fully, but it comes from the Stars! exe itself and is 100% accurate. Deal

EDIT: They not only used the reverse engineered code, they seem to also have a slightly better understanding of it. Twisted Evil

That "equivalent of averaging an infinite number of random planets" is not done randomly at all. It's wholly deterministic for a given race design. Teleport

Odds are it's not completely fair across all possible race designs, though, by giving more points to habs that aren't so much better than other hab schemes that get less points. Sherlock

I built something like that to help ConstB debug his C++ calculations. Never published it, though, I think. Rolling Eyes

I haven't looked into the code enough to know what it's doing about hab ranges. It could be that it is doing a theoretical spread.

As for the code, does this look like a bug to anyone else?
	for (h = 0; h < 3; ++h)
	{
		int DesireFactor;
		switch (h) {
		case 0:
			TTCorrFactor = TerraformFactor0();
			DesireFactor = 7;
			break;
		case 1:
			TTCorrFactor = TerraformFactor1();
			DesireFactor = 5;
			break;
		case 2:
		default:
			TTCorrFactor = TerraformFactor2();
			DesireFactor = 6;
			break;
		}



If you do a ++h wouldn't that cause h to never be 0, therefore you'd never get that DesireFactor of 7?

Nevermind, I looked it up, the pre-increment makes no difference in a for loop.

It's an h++ in my code. Should work the same, tho. Rolling Eyes

for (h = 0; h < 3; ++h)


the difference between h++ and ++h the is order of the incrementing of h and evaluation of the expression as a whole:
++h increments h before the evaulation and thus affects the evaluation.(preinc)
h++ increments h after the evaluation and thus does not affect the evaluation.(postinc)

The simplest examples are:
h=1;
x=(++h);
//A

h=1;
y=(h++);
//B
at both points (A&B) h has been incremented so h=2 but at A, x=2 and at B, y=1.

The third part of the for loop tuple is a statement to be run after each iteration. As a stand alone statement not included as part of a larger expression, both h++ and ++h have the same effect since the evaluation is never used - such as in a for loop.

Also, pre-increment is faster, because it doesn't create a temporary copy, so it is preferred.

Lucky me, this race points calculation exposed a bug in my planet hab value calculation.

If you are a regular old humanoid with 20,80 habs in all categores, and you come across a planet that is (20, 20, 20), what is your growth rate? My algorithm is showing a growth rate of 0% for that least ideal planet. For a planet of (80, 80, 71) I'm getting a growth rate of 3%. Does this sound correct?

My calculations appear to be slightly off. The standard humanoid race comes out at a value of 26, but when I change the cost of mines it is sways way more than the standard race wizard. This guy's race wizard appears to be more accurate:

http://www.gible.net/WebStars/WebStars%20-%20RW.html

Anyone know who's that is and whether the source is published somewhere?

I emailed his address and it bounced back. I did find a flash decompiler (for Mac even!) that allowed me to peruse a terribly obfuscated version of his source code and I determined that his logic was the same as the freestars logic. At the end he divided his advantage points by 3, which freestars was doing at a later step, and I did see it.

My code is mostly functional though a bit off. I think my planet hab calculations are to blame because making a tri-immune race comes out with the correct numbers.
