my box collider won't work

a) my player cant die on the game b) can't input a score c) wont load scene when the player is on collision
my columns are already tagged as enemy
there is a box colllider in the prefab in the middle of the column to get a point
when it hits enemy it wont load to the score scene/scene 2

Code (CSharp):

1. public class Player : MonoBehaviour
2. {
3.  
4.     public Vector2 jumplength = new Vector2(0f, 300f);
5.     public float rightspeed = 3f;
6.     // Use this for initialization
7.     void Start()
8.     {
9.        
10.     }
11.  
12.     // Update is called once per frame
13.     void Update()
14.     {
15.         if(9>2){
16.             transform.Translate(Vector2.right * rightspeed*Time.deltaTime);
17.         }
18.         if (Input.GetKeyDown(KeyCode.Space) || Input.GetMouseButtonDown(0))
19.         {
20.             GetComponent<Rigidbody2D>().velocity = Vector2.zero;
21.             GetComponent<Rigidbody2D>().AddForce(jumplength);
22.          
23.         }
24.  
25.     }
26.     void Die()
27.     {
28.         SceneManager.LoadScene(2);
29.     }
30.  
31.     void OnCollisionEnter2D(Collider2D player)
32.     {
33.         if (player.gameObject.tag == "enemy")
34.         { Die(); }
35.     }
36. }
37.  

this is the code of game object with the box collider
void onTriggerEnter2D(Collider2D collider)
{
if (collider.gameObject.tag == "Player")
{
score.addPoint();

}
}

}

this is the code for the GUI text
public class score : MonoBehaviour {


static int result = 0;
static int highscore = 0;

static public void addPoint()
{
result++;
if (result > highscore)
{
highscore = result;
}
}

// Update is called once per frame
void Update () {
GetComponent<GUIText>().text ="" +result;

}

}

 

31. void OnCollisionEnter2D(Collider2D player) should be with Collision2D. void OnCollisionEnter2D(Collision2D player)

void onTriggerEnter2D(Collider2D collider) change to: void OnTriggerEnter2D(Collider2D collider).

And do you have enabled trigger checkbox for OnTriggerEnter2D on boxcollider ?

 

that is my box collider and i have changed things you said but it still won't add points and die when it collides with other objects

 

box collider will not work with OnTriggerEnter2D. You should use BoxCollider2D.

 

Also for it to work, 1 of the 2 colliders that you want to collide must have a rigidbody2d ( Set the rigidbody2d to kinematic so it wont be affected by physics etc)

 

Code (CSharp):

1. public class scorepoint : MonoBehaviour
2. {
3.     void OnBoxCollider2D(Collider2D collider)
4.     {
5.         if (collider.gameObject.tag == "Player")
6.         {
7.             score.addPoint();
8.            
9.         }
10.     }
11.  
12. }

 

like that?

 

No, the script should be: void OnTriggerEnter2D.
On your gameobject "scoreinput" you have added box collider. You cannot mix 2d with 3d physic. Replace it with box collider 2d.

- make player: add box collider 2d, rigidbody 2d
- make scoreinput: add your script, box collider 2d (set it to trigger)

in script

Code (CSharp):

1. public class scorepoint : MonoBehaviour
2. {
3.     void OnTriggerEnter2D (Collider2D collider)
4.     {
5.         if (collider.gameObject.tag == "Player")
6.         {
7. //add line for test, you shoud see it in log if all works.
8. Debug.Log ("worked");
9. score.addPoint();
10.         }
11.     }
12. }
