|
* 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: Zero range <NUMBER>
|
|
* 1: Bore height <NUMBER>
|
|
* 2: Weapon <OBJECT>
|
|
* 3: Ammo <CLASS>
|
|
* 4: Magazine <CLASS>
|
|
* 5: Advanced Ballistics enabled? <BOOL>
|
|
*
|
|
* Return Value:
|
|
* zeroAngleCorrection <NUMBER>
|
|
*
|
|
* Example:
|
|
* [5, 6, gun, ammo, magazine, true] call ace_scopes_fnc_calculateZeroAngleCorrection
|
|
*
|
|
* Public: No
