Ballistic Calculator

[conKORD 10]

Which of them especially?

[conKORD 10]

Which weapon in OA are unable to use calculator? I need to know concretely to fix it.

[b00ce 160]

Wow, disregard that. Apparently you need to move the piece around a bit. I don't know why I never got it working with the OA stuff before. Interesting.

Also, is there a way to get it client-side again? I would really like to be able to provide fire-support on servers that don't have this addon. And it's inconvenient on my end, because I can never remember the script stuff to put it in my inventory. :p

conKORD, have you tried arty in the latest patch?

[conKORD 10]

OA beta? No. Only with 1.52.

EDIT

Oh . . . 1.54 is released. Downloading.

About new BIS arty.

Works nice, looks like does nothing with shell, it can be tracked with bulletcam. Now arty an mortars have variable charges. Now shells while flying aligns with their velocity vector. Finally, Grad and MLRS is useful.

Comparing to BalCa.

Not enabled to grenade launchers, does no provide low solution, only high.

Currently BalCa can't read new initial velocities implemented with variable charges and don't work with arty and mortars.

In 1.54 very originally solved problem with influence of airfriction on ballistic calculations. Now there is no airfriction for arty shells, mortar shells, and Grad/MLRS rockets :D

2) More important - rocket speed after using thruster is not equal (_initSpeed+(_thrustTime*_thrust)) :confused: . In ArmA speed of rocket ~20% lesser than in formula. I need to know reasons of it or to get right formula for speed. It would be perfect if BIS employees will answer to me.

Problem solved. Now in OA 1.54 Grad/MLRS have no thruster. Them appears with initial speed 445m/s and behave as normal shells in flight.

Balca v1.4demo

New

• Works with Grad and MLRS.
  
• Additional crosshair that helps to aim in direct fire mode.
  
• Rangefinder. Enable BalCa, aim to target place and push "space".
  
• Added support for variable arty charges.
  

Changed

• Recalculates solutions when fire mode or current magazine changed.
  
• No more compatible with ArmA2, works only with OA.
  
• Do not requires CBA.
  

Comparing it with the new BIS arty.

• Still works with every weapon, not only where shells are with disabled airfriction.
  
• Also provides low solution, so minimal range for arty does not exist.
  
• Should be more handy to cover area.
  

Notes

• It is demo/prerelease version, so it works with every weapon and every vehicle. Therefore server key not included.

Is there any way to use BalCal without the item in your inventory (i.e. clientside)?

[conKORD 10]

Balca v1.4demo works without item in inventory.

[gamers2000 10]

I understand that 1.4 does not support Vanilla A2 w/o AO, so is it possible with 1.3?

[conKORD 10]

Ok, I'll do it soon. Likely, if BIS chose that arty computer no needs any additional requirements, BalCa will not require item in inventory to work. Maybe BalCa in inventory will allow player to use ballistic calculator with every vehicle.

[b00ce 160]

It seems as though the calculator will stop working after a while. It will work just fine and then all of the sudden it won't work on a vehicle (namely the US Army M119, so it should have worked) that I just used it with.

[gamers2000 10]

Thanks conKORD! Awesome mod, by the way. Thought I'd just put that there ;)

This. I really don't know how I got by without. :o

What happened? BalCa display stops refreshing? Or string in action menu don't appears? Is any errors in RPT?

[b00ce 160]

The action menu option disappears. I don't know where I'd find an error report, sorry.

[conKORD 10]

In 1.3 after disabling BalCa you may need to reenter vehicle to get action menu option again.

[conKORD 10]

Balca v1.4

New

• Works with Grad and MLRS.
  
• Rangefinder. Enable BalCa, aim to target place and push "space".
  
  By default rangefinder is enabled on BMP3, AAV, BTR90. To enable it to other vehicles add balca_rangefinder = 1; to vehCfg.

  
  

• Additional crosshair that helps to aim in direct fire mode. It appears only on vehicles with enabled rangefinder.
  
• Added support for variable arty charges.
  

Changed

• Now works without item in inventory. But BalCa item allows you to use it with every weapon on every land vehicle.
  
• Recalculates solutions when fire mode or current magazine changed.
  
• Works only at gunner's place in vehicle.
  
• Do not requires CBA.
  

1.4demo>>1.4 changes

• Now again compatible with ArmA2.
  

Comparing it with the new BIS arty.

• Still works with every weapon, not only where shells are with disabled airfriction.
  
• Also provides low solution, so minimal range for arty does not exist.
  
• Should be more handy to cover area.

Tried that, several times, Didn't work. :( It was in the editor, I spawned without the ability to use it, when I could before, which I thought was really weird.

[conKORD 10]

BalCa 1.5

• [+]Script preload, now BalCa will work faster.
  
• [+]By default BalCa now enabled on BAF GMG (british version of Mk19)
  
• [!]Minor issues in russian localisation.
  
• [!]Demo mission changed to "Proving ground"
  
• [-]In OA shell flytime has not been shown. Fixed.

Very nice, thx for the update! :)

Ballistic Calculator v1.5



Community Base addons

[conKORD 10]

BalCa v1.6

• [!]Removed RPT messages like Updating base class*
  
• [+]Reworked addon structure, added function BALCA_FNC_GET_SOLUTION that will return needed elevation to engage designated target.
  

With CBA function will be initialized automatically. Without - open balca window or execute

call compile preProcessFileLineNumbers 'x\addons\balca\init.sqf'

Input:

[_ndist,_altitude_impact,_initSpeed,_friction,[_minElev,_maxElev]]

_ndist - distance to target

_altitude_impact - relative target elevation

_initSpeed - initial bullet speed

_friction - airfriction of current bullet

Optional - [_minElev,_maxElev] - turret elevation limitation to speed up calculations.

Output:

[_reachable,[_low_solution,_ls_mult,_flytime_low],[_high_solution,_hs_mult,_flytime_high]]

_reachable - bool, target can be reached with current shell and current turret limitations

_low_solution - it is

_ls_mult - range multiplier. 1 means that if the barrel screw up by 1 degree above _low_solution - bullet drop at 100 meters further _ndist

_flytime_low - it is

Same for high solution.

Example:

_table = [];
for [{_dist = 100},{_dist <= 1200},{_dist= _dist + 100}] do {
_table set [count _table,[_dist,(([_dist,0,870,-0.00096] call BALCA_FNC_GET_SOLUTION) select 1) select 0]];
};
_table

as result we have ballistic table for SVD

[[100,0.0396113],[200,0.0847235],[300,0.136202],[400,0.195057],[500,0.262473],[600,0.339831],[700,0.428755],[800,0.531145],[900,0.649235],[1000,0.785648],[1100,0.943469],[1200,1.12633]]

Which @folder should we be using if we have arma2 and OA as a combined install? @balca_reloader or @balca_reloader_OA ??

[conKORD 10]

@balca_reloader_OA for CO

[Shinra123 10]

How select targets pn map I can not figure it. Please help
