Caliber calculation

[th3flyboy 0]

Hey, I'd like to know what the basis is for the caliber calculations in the configs. It's apparent they are not the actual size of the round, so how is it calculated?

It's based on the initspeed, typicalspeed, airFriction, and hit.

Q that really doesn't explain how the bullet caliber number is calculated...

It does...

The BulletBase has the caliber value of 1

class BulletBase: BulletCore
{
	caliber = 1;
}

Every other bullet relates to this value...for instance:

class B_9x18_Ball: BulletBase
{
	caliber = 0.33;
};

class B_545x39_Ball: BulletBase
{
	caliber = 0.5;
};

class B_556x45_Ball: BulletBase
{
	caliber = 0.5;
};

class B_127x108_Ball: BulletBase
{		
	caliber = 2.07;
};

ETC....

So as per Alex link, you can calculate the caliber size needed in the config...

Just to be clear... A 7.62x51mm ball round penetrates about 6mm of homogenous steel. So would a Sabot round that penetrates 600mm of RHA have a caliber of 100?

it depends on a number of factors actually, including how the surface you want to simulate 600mm RHA is setup.

the 6mm 7.62 penetration iRL has nothing to do with A2. You need to check the set values and have some tral and errors. There is no quick answer here

Lol. Thanks for the reply. I just wanted to shoot a sabot through a building and damage a BMP. Or have a sabot through 2 BMP's.

When you say "how the surface is set up" do you mean the bisurf stuff?

I was thinking that adjusting "caliber" in the weapon config would be much easier than going through all the models...

There should be a universal approach to this.

BTW, what is "iRL"?

Thanks again!

@max: i can always count on you to complete my posts ;)

sabot through a building should be possible. sabot through 2 bmps, i doubt it.

thing is, as it is now, rv engine does NOT allow this sort of penetrations afaik. you cannot have 2 kills with one bullet i am afraid. while the above seems to be true regarding characters, it also seems to be true when vehicles are concerned. i haven't done any sort if tests in this regard, but i am pretty sure the "bullet" is "consumed" on impact, or in fact inside the geometry/fire lod that it hits. a simple way would be to test it is by slowing down time (acctime) and creating a camera attached to the projectile via fire eventhandler and test it out on a number of targets. you could create a number of bullets types as well (could push the value in the config pretty high for testing purposes)
