### Description

Description:
Multiplies an array of numbers by a scalar or another array of numbers.
Groups:
Math - Vectors

### Syntax

Syntax:
numArray vectorMultiply multiplier
Parameters:
numArray: Array of Numbers - an array of any size - e.g vector 3D or 2D (the z coordinate was defaulted to 0)
multiplier: Number or Array of Numbers
Return Value:
Array of Numbers

### Examples

Example 1:
_newVector = [1,2,3] vectorMultiply 3; // returns [3,6,9]
Example 2:
[1,2,3,4] vectorMultiply [1,2,3,4]; // [1,4,9,16] [1,2,3,4] vectorMultiply 2; // [2,4,6,8] [1,2,3,4] vectorMultiply [2]; // [2,2,3,4] [2] vectorMultiply [1,2,3,4]; // [2,2,3,4] [1,2,3] vectorMultiply [1,2,3,4,5]; // [1,4,9,4,5]
Example 3:
private _eyePos = eyePos player; private _eyeDir = getCameraViewDirection player; // this is a normalized vector, i.e. its magnitude is 1 private _100mFurther = _eyeDir vectorMultiply 100; // since _eyeDir is normalised (length = 1m), multiplying it by 100 means 100m in that direction private _lookPos = _eyePos vectorAdd _100mFurther; // the position where player is looking 100m ahead
Example 4:
// Override firing to throw the player towards where he's aiming player allowDamage false; player addAction ["", { player setVelocity ((player weaponDirection "") vectorMultiply 20); }, "", 0, false, true, "DefaultAction"];
