I’m trying to make it to where the every time I click the target the picks a predetermined direction and moves that way. Is there something missing? Is my “programming grammar” correct?
```
var speed = 5;
var deer = 10;
var tap = 100;
var num = Random.Range(2,-2);
function Update () {
transform.position += transform.forward * Time.deltaTime * speed;
}
function OnMouseEnter() {
speed = 15;
TotalScoreScript.Points += deer + 10;
}
function OnMouseExit () {
speed = 5;
}
function OnMouseDown () {
TotalScoreScript.Points += tap + 100;
if(num=(-2)){
transform.Rotate(Vector3.up, -135 );
}
if(num=(-1)){
transform.Rotate(Vector3.up, -45 );
}
if(num=1){
transform.Rotate(Vector3.up, 45 );
}
if(num=2){
transform.Rotate(Vector3.up, 135 );
}
else(num=0){
transform.Rotate(Vector3.up, 0 );
}
}
```

If I understand your algoritm / idea, you want to make this script run an “animal NPC/AI” ?
and when I mouseover, the animal will panic simulated with speed 15? and mouse down = shot/fire? resulting in the animal changing direction?
For the “OnMouseDown”. Lets put that in a function called “ChangeDirection” instead. Then you can call it from more than one event if needed.
```
function ChangeDirection()
{
num = Random.Range(2,-2); // as I understand this one, its your direction? you could call it dir or direction to make it more logical?
// now instead of multiple IF... THEN... use a SWITCH... CASE to make it more easy
// if no CASE is a match for the variable, then DEFAULT is choosen. You can ommit a default too.
var rotate;
switch(num)
{
case -2:
rotate = -135;
break;
case -1:
rotate = -45;
break;
case 1:
rotate = 45;
break;
case 2:
rotate = 135;
break;
default:
rotate = 0;
break;
}
// if direction should be changed
if(rotate!=0)
{
transform.Rotate(Vector3.up, rotate );
}
// add score
TotalScoreScript.Points += tap + 100;
}
```
suddently you can very easily also change the speed of the animal.

By default, Random.Range returns a float. This means the values you get from Random.Range(-2, 2) is a floating point number between -2 and 2, for example 1.5437. As a result, your will hardly ever be == 1.
Two ways to solve the problem, use
```
var num:int = Random.Range(-2, 2);
```
This way you get an integer instead of a float.
The other way would be a range check.
P.s to test for equality use ‘==’ not ‘=’
