Help me with cs0501

I m new at this world and I have this error : Assets/code/RoutePoint.cs(10,18): error CSO501: RoutePoint.OnTriggerEnter(Collider) must declare a body because it si not marked abstracted, extem, or partial

This is my script

using System.Collections;
using System.Collections.Generic;
using UnityEngine;

public class RoutePoint : MonoBehaviour
{
public RoutePoint nextPoint;
public GameObject model;
public bool isActiveForPlayer;
private void OnTriggerEnter(Collider other);
// Start is called before the first frame update
void Start()
{

}

// Update is called once per frame
void Update()
{
    
}

}

You can fix your own typing mistakes. Here’s how:

Remember: NOBODY here memorizes error codes. That’s not a thing. The error code is absolutely the least useful part of the error. It serves no purpose at all. Forget the error code. Put it out of your mind.

The complete error message contains everything you need to know to fix the error yourself.

The important parts of the error message are:

  • the description of the error itself (google this; you are NEVER the first one!)
  • the file it occurred in (critical!)
  • the line number and character position (the two numbers in parentheses)
  • also possibly useful is the stack trace (all the lines of text in the lower console window)

Always start with the FIRST error in the console window, as sometimes that error causes or compounds some or all of the subsequent errors. Often the error will be immediately prior to the indicated line, so make sure to check there as well.

Look in the documentation. Every API you attempt to use is probably documented somewhere. Are you using it correctly? Are you spelling it correctly? Are you structuring the syntax correctly? Look for examples!

All of that information is in the actual error message and you must pay attention to it. Learn how to identify it instantly so you don’t have to stop your progress and fiddle around with the forum.
