hi guys 
I want that my zombies, when follow the player, make little jumps.
This is the script:
// Enemy AI
private var ismoving=false; // is moving the Enemy?
private var target : GameObject; // Enemy´s Target
var enemyVelocity = 5; // Enemy´s Velocity
private var damage :int=5; // Enemy's Damage
private var attakingVelocity = 1; // attack time rate
private var collisionDistance = 1.5;
var audioIdle : AudioSource;
function Start(){
// set the target and starts to moving at start
target = GameObject.FindWithTag("Player");
ismoving = true;
}
function Update () {
//: if not moving, wait one second, else, if the enemy have a target, chase that target (player)
if(!ismoving)
{
attakingVelocity += Time.deltaTime;
if(attakingVelocity > 1)
{
ismoving=true;
attakingVelocity = 0;
}
}
else
{
if(target)
ChasePlayer(target);
}
}
function ChasePlayer(target:GameObject)
{
// look at target
var direction = target.transform.position - transform.position;
direction.y=-10.0;
var rotation = direction;
//rotate smoothly to the target´s direction
transform.rotation = Quaternion.Slerp (transform.rotation, Quaternion.LookRotation(direction), 3 * Time.deltaTime);
transform.eulerAngles = Vector3(0, transform.eulerAngles.y, 0);
// stablish the orientation
var forward = transform.TransformDirection(Vector3.forward);
//Stablish the velocity variance depend on the target´s direction
var speedModifier = Vector3.Dot(forward, direction.normalized);
speedModifier = Mathf.Clamp01(speedModifier);
//if target reaches a certain distance between him and the player, hurts the player and stop moving, else, it continues moving
if (Vector3.Distance(transform.position, target.transform.position) < collisionDistance) // Collision Distance is a var
{
ismoving=false;
}
else
{
direction = forward * enemyVelocity * speedModifier;
if(GetComponent (CharacterController))
GetComponent (CharacterController).SimpleMove(direction);
else
{
rigidbody.velocity=direction;
rigidbody.velocity.y=-1;
}
}
yield;
}
thanks
