Assets\enemy.cs(9,9): error CS0120: An object reference is required for the non-static field, method

Code (CSharp):

1. using System.Collections;
2. using System.Collections.Generic;
3. using UnityEngine;
4.  
5. public class enemy : MonoBehaviour
6. {
7.    private void  OnCollisionEnter2D(Collision2D collition)
8. {
9.     if (Collision.collider.GetComponent<bird>() != null)
10.     {
11.        Destroy(gameObject);
12.     }
13. }
14.  
15.  
16.  
17. }
18.  

fix

 

Should be using "collition" (your parameter on this function) instead of "Collision" - you want the collider of this particular collision event (which is what "non-static" means in this context). "Collision" (the class) would be if you need something relating to the concept of a Collision (which would be "static").

 

like this

Code (CSharp):

1. using System.Collections;
2. using System.Collections.Generic;
3. using UnityEngine;
4.  
5. public class enemy : MonoBehaviour
6. {
7.    private void  OnCollisionEnter2D(Collision2D collition)
8. {
9.     if (particular collision.collider.GetComponent<bird>() != null);
10.     {
11.        Destroy(gameObject);
12.     }
13. }
14.  
15.  
16.  
17. }
18.  

 

Nowhere did I tell you to add the word "particular" into your code?

What you need in that place is "collition" - the name of the parameter you used on line 7.

 

OnGUIDepth changed: was 0 is 1. Event type was 0 help

Code (CSharp):

1. using System.Collections;
2. using System.Collections.Generic;
3. using UnityEngine;
4.  
5. public class enemy : MonoBehaviour
6. {
7.    private void  OnCollisionEnter2D(Collision2D collition)
8. {
9.     if ( collition.collider.GetComponent<bird>() != null);
10.     {
11.        Destroy(gameObject);
12.     }
13. }
14.  
15.  
16.  
17. }

 

That sounds like a completely separate issue?

I just noticed: like 9 should not have a semicolon at the end.

 

its still there

 

You've been posting a lot of threads in a short amount of time that are all related to basic syntax or logic errors, and quite frankly, come off as spammy & low-effort.

Don't just post a script and say "fix"; describe your problem and what you've already tried to fix it.
If you haven't tried fixing any of your problems yourself, then how do you expect to learn how to do so if you just keep passing them on the forums for someone else to figure out?

Please take the time to do some beginner scripting tutorials; you'll save yourself a lot of time in the long run:
