Make a "Guard" Script?

Hello. I am making a game, And in the game, there are supposed to be enemies that follow you and when you touch them, you die. Now I already have a script so the enemies follow you. It's this one :

vartarget : Transform;
varmoveSpeed = 3;
varrotationSpeed = 3;

varmyTransform : Transform;

functionAwake()
{
myTransform = transform;
}

functionStart()
{
target = GameObject.FindWithTag("Player").tranform;

}
functionUpdate () {
myTransform.rotation = Quaternion.Slerp(myTransform.rotation,
Quaternion.LookRotation(target.position - myTransform.position), rotationSpeed*Time.deltaTime);

//movetowardstheplayer
myTransform.position += myTransform.forward * moveSpeed * Time.deltaTime;


}
But I want to make the enemy only start following the player if the player is close to it. I know you're supposed to use a Vector3.distance script, but I am a total noob at these things. Help would be greatly appreciated!

 

Make a 'followPlayer' boolean in your variable declarations. Then run a distance check in your update function. Add an if statement around your movement code so it only runs if the followPlayer boolean is true.

Code (CSharp):

1. bool followPlayer = false;//defined somewhere
2. float dist = 1.5f;// how close you get before they follow
3.  
4. if(followPlayer == false && Vector3.Distance(player.transform.position, transform.position) < dist)
5. {
6.     followPlayer = true;
7. }

Code (CSharp):

1. if(followPlayer)
2. {
3.     myTransform.position += myTransform.forward * moveSpeed * Time.deltaTime;
4. }

 

Um... Sorry but I don't know Boolean, is it possible in Javascript?

 

Hi,

Boolean is a basic variable type. It is a simple "True" or "False" variable. In order to call a new boolean, simply add this :

var distPlayer : boolean = false;

And to use it, remember that there is no other value than true or false.

Hope I helped.
