(ArmA3 1.22) Algorithm:
Vector = [x,y,z]; scalar = a; Result = [(x * a),(y * a),(z * a)];It is recommended to use vectorMultiply instead of BIS_fnc_vectorMultiply. This is a very useful function, as it can be used with the velocity command to move an object from one position to another. (ie <vector1> to <vector2>) - ensure both positions are found using getPosASL._obj setVelocity (((getPosASL _target) vectorDiff (getPosASL _obj)) vectorMultiply 2);
