Unity3D Tutorial | Game object move towards another game object

One game object move towards another game object in Unity3D tutorial:

I am gonna show you how you can move one game object towards another in Unity3D script via java script.

Scanerio:

Suppose there are enemies in the scene and you want them to move towards a certain position when game starts.

Game object move towards another game object
                         Game object move towards another game object


Solution:

This is how you can do it:

take a reference variable target and give target position to it in hierarchy.


function Update () {

step = speed * Time.deltaTime;

var diff = target - transform.position;

// Move our position a step closer to the target.
transform.position = Vector3.MoveTowards(transform.position, target, step);

}



Attach this script of game object and it will move towards in the speed towards the target.


Ask any question to me in comments.

Unity3D tutorial | Game Object Looking at another gameobject

This tutorial will help you find how your one game object can look at another object at all times.

Scenario: 

We have enemies and player in a scene. Player is constantly moving from one place to another. Enemies should be intelligent enough to look towards the player every frame.

Solution:

This can done like:


function Update () {

 // get direction of player
        _direction = (Target.gameObject.transform.position - transform.position).normalize
         
        // create the rotation we need to be in to look at the target
        _lookRotation = Quaternion.LookRotation(_direction);
         //rotate us over time according to speed until we are in the required rotation
         transform.rotation = Quaternion.Slerp(transform.rotation, _lookRotation, Time.deltaTime * RotationSpeed);

}


Throw this script of any enemy object and pass the "Target" variable of player as reference to it. And it is all done

If any question, plz ask me.
