How to give your enemy gun inaccuracy

Questions & Answers
1

How can I create a gun that will not shoot 100% accurate in the direction of a raycast? For example, to give it a little bit of an inaccuracy so that the Enemy AI will not have 100% shooting accuracy for every shot. I’ve figured out my own way but I’d like to see how others handle it.

Here is my implementation. How have others done it? The main purpose of this question was to share my technique because I was not able to find any resources about how to do it but I thought it was something most people would find useful

//Takes a vector and returns a new vector that is slightly variated in direction
//0 = 100% accurate and the larger the number, the less accurate
//last 2 params are optional and will draw both the original vector and the new varied vector
public static Vector3 VectorSpread(Vector3 origVector, int accuracy, bool showDebug = false, Vector3 debugPosition = default(Vector3)){
    float myIntx = (float)Random.Range(-accuracy,accuracy)/1000;
    float myInty = (float)Random.Range(-accuracy,accuracy)/1000;
    float myIntz = (float)Random.Range(-accuracy,accuracy)/1000;
    Vector3 newVector = new Vector3(origVector.x + myIntx, origVector.y + myInty, origVector.z + myIntz);

    if(showDebug){
        Debug.DrawRay(debugPosition, origVector * 1000F, Color.cyan);
        Debug.DrawRay(debugPosition, newVector * 1000F, Color.red);	
    }
    return newVector;
}
