Interpretation of the Figures for Shells in the Common Resolution Folder/Iceman

[frinik]

Hello Iceman.I need your assistance!It seems to me that long ago on the Sukhoi/Avia forum you had posted about the what the figures for the Shells meant in the Common resolution folder.I have been unable to find that post!Would you be able to help?

Here's the line for a grenade for example:

RGD33,0x10,%SHELL_HE%,RGD33,25,1,20,0.5,0,1,1,0,0.5,0.18,0.01,9.81,10,10,0.1,0,1,1,1,expl_gndl*,expl_techl*,expl_buildl*,expl_water*,expl_human*,fly1,0,40,1,txt_shell_rgd33,he_expl_pat,rico_pat,piece_pat,0,1,1,1,1,0x60000000,0,1,-1,RGD33,RGD33;


I seem to remember for example that the second figure( 25 )refers to the velocityexpressed in metres per second and I think the 11th(0.18) refers to the quantity of explosive in the object .However I cannot recall what the other figures mean?

As well what is the rate set for the infnatry throwing grenades in the game?

Hi Frinik,

If you're still looking for that thread, here it is:

Great Stuff Kyth!Thanks this is exactly what I was looking for....

Can anyone tell me how the numbers for armor piercing ammo relates to thickness in mm? a setting of 1 is how many mm and at what range?  is that the effective range?

There's a formula for that.
Actually, many formulas, reflecting the huge number of variables such as face-hardened armour, armour quality etc. etc.
I'm not sure which one the game uses 

Central to all the formulas is the mass of the projectile, and the striking velocity squared. Increase either one, or both, and the penetration increases.

Sorry I can't be any more specific than that, maybe Mistwalker and Frinik would like to add their opinions?

Nobody knows that. Except developers. Adjustments for the most (but not all) of the shells made by countless ingame tests and according to real field tests.

There's 3 important parameters (for APSC an HEAT shells - 4), as Kyth said it's speed, mass and penetration ability.

  I have played with the armour piercing values for example for the JS-2 I increased the given value of 0.97 to 1.05, Tiger II 0.97 to 1.01, Panther 0.89 to 0.90 and Tiger I from 0.75(set in Tiger 0.97 mod) to 0.85 and each fraction seems to increase piercing action of the AP shell but also increases the tendency of the shells to ricochet. I am not sure how you can co-relate the values in game say 1 to the penetrating value in mm of a given shell .Not sure even if they used armour thickness at a 60 or 90 degree angle not how they factored the sloping effect of some of the tanks armour(T34, Panther , Tiger II, JS).I also played with the concussive values and frag with the aim of increasing the power of HE shells against the infantry but with mixed results.
