I've been looking over certain classes to see why some behaviour seems strange. One of these oddities is the B-17's super delicate fuel tanks (and for other bombers, too). The net result is what seems to be a too-great ease in knocking them down; even a quick burst with small calibre fire, once getting a tank to smoke, often progresses to fire and destruction in fairly short order. If we look at a few getEnergyPastArmor() values:

B-17: 0.06 (same for B-24, B-29)
B-25: 0.2
F4F: 0.8
A6M: 0.1, with randomness of 45%
B5N: 0.1, with randomness of 25%

The B-17's tank is more delicate than than the Zero's, and with not even a chance of a qualifying hit not causing damage!

I'm starting to wonder if some degree of rationalizing of damage characteristics might be in order...

For the Beaufighter we have this outright error for the fuel tanks in BEAU.class:

if(getEnergyPastArmor(2.1F, shot) > 0.0F && World.Rnd().nextFloat() < 10.25F)


World.Rnd().nextFloat() generates a random value between 0 and 1. By testing against 10.25, the condition is always true. I suspect the correct comparator is 0.25, not 10.25. Of course, this would reduce instances of damage by hits of qualifying energy by a factor of 4, making the tanks effectively 'tougher' still.

Note also the large value of 2.1 for the penetrating energy as compared to the values in the first post.


ADDED IN EDIT: The SBD has the very same code error (and energy threshold); one is probably a copy of the other.

And why is the Pete (F1M) so comparatively hard to light up for a Japanese bird? The threshold Energy value of 0.8 in combination with a 45% probability for incurring damage, that's why. This effectively makes the fuel tanks a bit more than 2X 'tougher' than the Wildcat's!

Moreover, damage will increment the tank damage state by a value of 1. For a number of other Japanese crates, such as the Zero, a damaging hit will increment the tank damage state by 2 steps, leading more quickly to fire and destruction.

from Pete_v1.class

Code: [Select]

if(s.startsWith("xxtank"))
{
int l = s.charAt(6) - 49;
if(l > 3)
return;
if(getEnergyPastArmor(0.8F, shot) > 0.0F && World.Rnd().nextFloat() < 0.45F)
{
if(FM.AS.astateTankStates[l] == 0)
{
debuggunnery("Fuel Tank (" + l + "): Pierced..");
FM.AS.hitTank(shot.initiator, l, 1);
FM.AS.doSetTankState(shot.initiator, l, 1);
}
if(World.Rnd().nextFloat() < 0.008F || shot.powerType == 3 && World.Rnd().nextFloat() < 0.6F)
{
FM.AS.hitTank(shot.initiator, l, 1);
debuggunnery("Fuel Tank (" + l + "): Hit..");
}
}
return;
} else
{
return;
}

Once again, a very interesting subject.
I've seen that in my game the B-17s have been modified to have a value of 1.8.

Indeed, strange stuff.

But sounds you're the right in charge to crack the coconut.
