* Builds a rangeTable line for a certian range, given muzzle velocity and air friction, returns [] if out of range.
|
|
*
|
|
* Arguments:
|
|
* 0: Muzzle Velocity <NUMBER>
|
|
* 1: Air Friction <NUMBER>
|
|
* 2: Range To Hit <NUMBER>
|
|
*
|
|
* Return Value:
|
|
* Range Table Line Data (see return line) <ARRAY>
|
|
*
|
|
* Example:
|
|
* [300, -0.0001, 3000] call ace_mk6mortar_fnc_simulateCalcRangeTableLine
|
|
*
|
|
* Public: No
