So today we are going to be making and object follow the mouse cursor in unity.
{: .note .info}
Currently I am using Unity 2019.4.10, So this can be applicable for future versions and maybe some older ones too.
We shall start with the default Sample Scene
Download Assets
Lets start by creating a C# script and call it MouseCursorFollow.cs
so this is the default script you will get
{% highlight cs %} using UnityEngine;
public class GameManager : MonoBehaviour{
//Use..
void Start(){
}
//....
void Update(){
}
}
{% endhighlight %}
You can remove both the comments.
Now we are going to declare all our variables.
{% highlight cs %}
public Camera myCam;
Vector2 mousePosition;
RigidBody2D rb;
{% endhighlight %}
Now reference the scene camera to the game object which has this script attached.
Next attach a RigidBody2D component to this game object and set the gravityScale to 0
Get the RigidBody2D component through the start function.
{% highlight cs %}
void Start(){
rb = GetComponent();
}
{% endhighlight %}
Now we will set our local mousePosition variable to the actual mousePosition
and convert it with Screen to World point function from our cam.
{% highlight cs %}
void Update(){
mousePosition = myCam.ScreenToWorldPoint(Input.mousePosition);
}
{% endhighlight %}
And we move our current position to the mousePosition with MovePosition from RigidBody2D.
{% highlight cs %} void Update(){ mousePosition = myCam.ScreenToWorldPoint(Input.mousePosition); rb.MovePosition(mousePosition); } {% endhighlight %}
So this is the final script.
{% highlight cs %} using UnityEngine;
public class GameManager : MonoBehaviour
{
public Camera myCam;
Vector2 mousePosition;
RigidBody2D rb;
void Start(){
rb = GetComponent<RigidBody2D>();
}
void Update(){
mousePosition = myCam.ScreenToWorldPoint(Input.mousePosition);
rb.MovePosition(mousePosition);
}
}
{% endhighlight %}
Now go into the unity editor and hit play.
Everything should work as expected.
