Description

Description:
Rotates both vectorDir and vectorUp on 3 axes: z (yaw), x (pitch) and y (roll). Positive angle direction is according to the right hand rule.
The vectors are rotated first on z axis then on x axis then on y axis. For example standard [[0,1,0],[0,0,1]] pair rotated 90 degrees on every axis will result in [[0,0,1],[0,-1,0]]

Syntax

Syntax:
[vectorDirAndUp, yaw, pitch, roll] call BIS_fnc_transformVectorDirAndUp
Parameters:
[vectorDirAndUp, yaw, pitch, roll]: Array
vectorDirAndUp (Optional): Array in format [vectorDir, vectorUp]. Default: [[0,1,0],[0,0,1]]
yaw (Optional): Number - yaw angle. Default: 0
pitch (Optional): Number - pitch angle. Default: 0
roll (Optional): Number - roll angle. Default: 0
Return Value:
Array in format [vectorDir, vectorUp]

Examples

Example 1:
private _vDirUp = [[vectorDirVisual uav, vectorUpVisual uav], 0, 0, 90] call BIS_fnc_transformVectorDirAndUp;
Example 2:
Create UAV object and make it pitch with mouse up/down and roll with mouse left/right: uav = "B_UAV_05_F" _this select 2, _this select 1 ] call BIS_fnc_transformVectorDirAndUp ); }];
