Unity 2d Platforming Enemy death in C# ?

Hey,

I'm very new to unity and I've been doing some basics (movement, Trigers for automatic doors) Been watching a bunch of tutorials.

I have made spikes with a Trigger, yet if I use it on an enemy he falls through the map, so I need a collider but don't know how or what to rewrite how.

Best would be a simple script that I can add to an object that has my Enemy AI which has the collider that kills me and makes me respawn at the start. Preferably with some //notes so I see what you did.

Thanks a lot in advance, appreciate it a lot



My Trigger for Death:

I also have the levelManager and Checkpoints in separate ones

Code (CSharp):

1. using UnityEngine;
2. using System.Collections;
3.  
4. public class KillPlayer : MonoBehaviour {
5.  
6.     public LevelManager levelManager;
7.  
8.     // Use this for initialization
9.     void Start () {
10.         levelManager = FindObjectOfType<LevelManager>();
11.     }
12.    
13.     // Update is called once per frame
14.     void Update () {
15.    
16.     }
17.     void OnTriggerEnter2D(Collider2D other)
18.  
19.     {
20.         if(other.name == "Player")
21.         {
22.             //levelManager.RespawnPlayer();
23.             Application.LoadLevel ("Class Movement Script stuff");
24.         }
25.     }
26.  
27. }
28.  

My enemy AI:

Code (CSharp):

1. //variable declarations
2. var Distance;
3. var Target : Transform;
4. var lookAtDistance = 25.0;
5. var attackRange = 15.0;
6. var moveSpeed = 5.0;
7. var Damping = 6.0;
8.  
9.  
10. // main update function
11. function Update ()
12. {
13.     Distance = Vector3.Distance(Target.position, transform.position);
14.    
15.     if (Distance < lookAtDistance)
16.     {
17.         GetComponent.<Renderer>().material.color = Color.yellow;
18.         lookAt();
19.     }
20.    
21.     if (Distance > lookAtDistance)
22.     {
23.         GetComponent.<Renderer>().material.color = Color.green;
24.     }
25.    
26.     if (Distance < attackRange)
27.     {
28.         GetComponent.<Renderer>().material.color = Color.red;
29.         attack ();
30.     }
31. }
32.  
33. function lookAt ()
34. {
35.     var rotation = Quaternion.LookRotation(Target.position - transform.position);
36.     transform.rotation = Quaternion.Slerp(transform.rotation, rotation, Time.deltaTime * Damping);
37. }
38.  
39. function attack ()
40. {
41.     transform.Translate(Vector3.forward * moveSpeed * Time.deltaTime);
42. }
43.  

 

Bump,

Please help :/

 

So your problem is that you have spikes with a trigger but enemies fall through it? Exactly you need to replace it with a collider.

I assume you already have a collider, but IsTrigger is set to true. Set it to false and replace your following code

Code (CSharp):

1.  
2. void OnTriggerEnter2D(Collider2D other)
3. {
4.         if(other.name == "Player")
5.         {
6.             //levelManager.RespawnPlayer();
7.             Application.LoadLevel ("Class Movement Script stuff");
8.         }
9. }
10.  

with

Code (CSharp):

1.  
2. void OnCollisionEnter2D(Collider2D other){
3.         if(other.name == "Player"){
4.                    //levelManager.RespawnPlayer();
5.                    Application.LoadLevel("Class Movement Script stuff");
6.         }
7. }
8.  

And that should do it, however there may be some errors because I wrote this off the top of my head, hopefully it'll atleast set you in the right direction.

 

Code (CSharp):

1. using UnityEngine;
2. using UnityEngine.SceneManagement;
3. using System.Collections;
4.  
5. public class Enemy : MonoBehaviour
6. {
7.     void OnCollisionEnter2D(Collision2D coll)
8.     {
9.         if (coll.gameObject.tag == "Player")
10.         {
11.             SceneManager.LoadScene("Your Scene name here");
12.         }
13.     }
14. }

So this worked for me
