ArgumentNullException: Value cannot be null. parameter name: Source
Hi :) i am making a 2D game were the player can jump on enemies and kind of bounce of them if that makes sense. Whenever i try to jump of a enemy i don't get the "bounce" and i get a error
ArgumentNullException: Value cannot be null. parameter name: Source
Enemy.JumpedOn () (at Assets/Scripts/Enemy.cs:23) PlayerController.OnCollisionEnter2D (UnityEngine.Collision2D other) (at Assets/Scripts/PlayerController.cs:100)
This s from playercontroller.cs:100
private void OnCollisionEnter2D(Collision2D other)
{ // Fiende och kollison med fiende
if (other.gameObject.tag == "Enemy")
{
Enemy enemy = other.gameObject.GetComponent<Enemy>();
if (state == State.falling)
{
enemy.JumpedOn();
Jump();
}
protected virtual void Start()
{
anim = GetComponent<Animator>();
rb = GetComponent<Rigidbody2D>();
death = GetComponent<AudioSource>();
}
This is from Enemy.cs 23
public void JumpedOn()
{
anim.SetTrigger("Death");
death.Play();
rb.velocity = Vector2.zero;
rb.bodyType = RigidbodyType2D.Kinematic;
GetComponent<Collider2D>().enabled = false;
}
I know I'm a bit late but that might help someone else, So (gameObject) where the G is a small letter means this gameobject(Player) that mean you are trying to access a function in a script that is not even exist, so try delete the gameObject it's not necessary so the code will be like this:
private void OnCollisionEnter2D(Collision2D other)
{ // Fiende och kollison med fiende
if (other.CompareTag("Enemy"))
{
Enemy enemy = other.GetComponent<Enemy>();
if (state == State.falling)
{
enemy.JumpedOn();
Jump();
}
protected virtual void Start()
{
anim = GetComponent<Animator>();
rb = GetComponent<Rigidbody2D>();
death = GetComponent<AudioSource>();
}
hope i helped someone
other is a Collision2D type. It does not contain the CompareTag method. you have to reference the collider, game object, rigidbody, or transform of the Collision2D variable in order to access the CompareTag method, so it is required and your code will output an error
