|
* Calculates the zero angle correction for the new zero range based on current zero range and bore height (distance between bore- and sight axis)
|
|
*
|
|
* Arguments:
|
|
* 0: Old Zero range <NUMBER>
|
|
* 1: New Zero range <NUMBER>
|
|
* 2: Bore height <NUMBER>
|
|
* 3: Weapon <OBJECT>
|
|
* 4: Ammo <STRING>
|
|
* 5: Magazine <STRING>
|
|
* 6: Advanced Ballistics enabled? <BOOL>

*
|
|
* Return Value:
|
|
* zeroAngleCorrection <NUMBER>
|
|
*
|
|
* Example:
|
|
* [5, 6, 7, gun, ammo, magazine, true] call ace_scopes_fnc_calculateZeroAngleCorrection
