hello all

can anyone help me i got this script and i want to add gravity how can this be done

var target : Transform; //the enemy's target
var moveSpeed = 3; //move speed
var rotationSpeed = 3; //speed of turning
var gravity:float = 20.0;
var Lives = 3;
private var dead = false;

private var moveDirection:Vector3 = Vector3.zero;

var myTransform : Transform; //current transform data of this enemy

function OnMouseDown()
{
    if(OnMouseDown)
    {
     Dead = true;
     Lives -= 1;
    }
print(Lives);
}

function Awake()
{
    myTransform = transform; //cache transform data for easy access/preformance
}

function Start()
{
     target = GameObject.FindWithTag("Player").transform; //target the player

}

function Update () {
    //rotate to look at the player
    myTransform.rotation = Quaternion.Slerp(myTransform.rotation,
    Quaternion.LookRotation(target.position - myTransform.position), rotationSpeed*Time.deltaTime);

    //move towards the player
    myTransform.position += myTransform.forward * moveSpeed * Time.deltaTime;

    //Apply gravity
    moveDirection.y -= gravity * Time.deltaTime;

    switch(Lives)
    {
         case 0:
         Destroy(gameObject);
         break;
    }

}

also iv recently added lives to it the Lives work but how can i make it that you got to be a specific distance before the player can attack the enemy this script is somewhere in that script but i just got it out so its easier to see

var Lives = 3;
private var dead = false;

function OnMouseDown()
{
    if(OnMouseDown)
    {
     Dead = true;
     Lives -= 1;
    }
print(Lives);
}

The problem is that, while you were changing ‘moveDirection’ in an attempt to lower the player’s Y co-ordinate value, ‘moveDirection’ itself was not being used, and therefore had no effect.

The same method of creating gravity is found on the Unity Scripting API under ‘CharacterController.Move’. However, this method uses a character controller to put ‘moveDirection’ to use.

Here is a link to the aforesaid page on the Scripting API: Unity - Scripting API: CharacterController.Move

I have edited the script so that it uses a character controller (which I attached to the player) to create the effect of gravity:

var target : Transform; //the enemy's target
var moveSpeed = 3; //move speed
var rotationSpeed = 3; //speed of turning
var gravity = 20.0;
var Lives = 3;
private var dead = false;

private var moveDirection : Vector3 = Vector3.zero;

var myTransform : Transform; //current transform data of this enemy

function OnMouseDown()
{ 
    if(OnMouseDown)
    { 
        Dead = true;
        Lives -= 1;
    }
    print(Lives);
}

function Awake()
{ 
    myTransform = transform; //cache transform data for easy access/preformance
}

function Start()
{
    target = GameObject.FindWithTag("Player").transform; //target the player
}

function Update ()
{ 
    var controller : CharacterController = GetComponent.<CharacterController>();

    //rotate to look at the player 
    myTransform.rotation = Quaternion.Slerp(myTransform.rotation, Quaternion.LookRotation(target.position - myTransform.position), rotationSpeed * Time.deltaTime);

    //move towards the player
    myTransform.position += myTransform.forward * moveSpeed * Time.deltaTime;

    //Apply gravity
    moveDirection.y -= gravity * Time.deltaTime;

    switch(Lives)
    {
        case 0:
            Destroy(gameObject);
            break;
    }

    controller.Move(moveDirection * Time.deltaTime);
}

Please inform me if you encounter problems using this edition of your script.
