Question Problem with EnemyWaveManger combined with EnemyMovement

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

public class EnemyMovement : MonoBehaviour
{
//public GameObject enemyObject;
private List<Vector2Int> pathCells;
private GameObject enemyInstance;
private int nextPathCellIndex;
private bool enemyRunCompleted;

private void Start()
{
nextPathCellIndex = 1;
enemyRunCompleted = false;
}

private void Update()
{
if (pathCells != null && pathCells.Count > 1 && !enemyRunCompleted && enemyInstance != null)
{
Vector3 currentPos = enemyInstance.transform.position;
Vector3 nextPos = new Vector3(pathCells[nextPathCellIndex].x, 0.2f, pathCells[nextPathCellIndex].y);
enemyInstance.transform.position = Vector3.MoveTowards(currentPos, nextPos, Time.deltaTime * 2);
if (Vector3.Distance(currentPos, nextPos) < 0.05f)
{
if (nextPathCellIndex >= pathCells.Count - 1)
{
enemyRunCompleted = true;
}
else
{
nextPathCellIndex++;
}
}
}
}



public void SetPathCells(List<Vector2Int> pathCells)
{
this.pathCells = pathCells;
}


}


this is my script with for enemyMovement
SetPathCells generate a route for my enemys (ps. my map generate everytime random ( this script alone is working if i instantiate one enemy in here

public class EnemyWaveManager : MonoBehaviour

}

}
}
return true;
}

private IEnumerator SpawnWave (Wave _wave)
{
Debug.Log("Spawning Wave:" + _wave.name);
state = SpawnState.SPAWNING;

for (int i = 0; i < _wave.enemies.Length; i++)
{
var temp = _wave.enemies;

for (int j = 0; j < temp.count; j++)
{
SpawnEnemy(temp.enemyInstance);
yield return new WaitForSeconds(1f / temp.rate);
}
}
state = SpawnState.WAITING;
yield break;
}

private void SpawnEnemy(GameObject _enemy)
{
Instantiate(_enemy, new Vector3(0, 0.2f, 5f), Quaternion.identity);
Debug.Log("Spawning Enemy:" + _enemy.name);
}
}


this is my script for setting up waves
this script is spawning the enemys correctly but the enemys dont move
i have added the Movement script to my enemy Prefab
and i added the enemy Prefab to the wavemanager.

btw im new to programming so sorry for my problem.
im already searching 2 weeks to solve this problem.
thanks for every help i get.

if i spawn a enemy he isnt moving at all.
tbh i dont have done debugging cause i dont know how.

 

Time to learn! It's not optional if you're going to write code. Writing code means you WILL write bugs, so debugging is part and parcel of the process of writing code.

Once you figure out what is happening, here is how to report your problem productively in the Unity3D forums:

http://plbm.com/?p=220

This is the bare minimum of information to report:

- what you want
- what you tried
- what you expected to happen
- what actually happened, especially any errors you see
- links to documentation you used to cross-check your work (CRITICAL!!!)

Here's how to get started debugging:

You must find a way to get the information you need in order to reason about what the problem is.

Once you understand what the problem is, you may begin to reason about a solution to the problem.

What is often happening in these cases is one of the following:

- the code you think is executing is not actually executing at all
- the code is executing far EARLIER or LATER than you think
- the code is executing far LESS OFTEN than you think
- the code is executing far MORE OFTEN than you think
- the code is executing on another GameObject than you think it is
- you're getting an error or warning and you haven't noticed it in the console window

To help gain more insight into your problem, I recommend liberally sprinkling

Debug.Log()

statements through your code to display information in realtime.

Doing this should help you answer these types of questions:

- is this code even running? which parts are running? how often does it run? what order does it run in?
- what are the values of the variables involved? Are they initialized? Are the values reasonable?
- are you meeting ALL the requirements to receive callbacks such as triggers / colliders (review the documentation)

Knowing this information will help you reason about the behavior you are seeing.

You can also supply a second argument to Debug.Log() and when you click the message, it will highlight the object in scene, such as

Debug.Log("Problem!",this);

If your problem would benefit from in-scene or in-game visualization, Debug.DrawRay() or Debug.DrawLine() can help you visualize things like rays (used in raycasting) or distances.

You can also call Debug.Break() to pause the Editor when certain interesting pieces of code run, and then study the scene manually, looking for all the parts, where they are, what scripts are on them, etc.

You can also call GameObject.CreatePrimitive() to emplace debug-marker-ish objects in the scene at runtime.

You could also just display various important quantities in UI Text elements to watch them change as you play the game.

If you are running a mobile device you can also view the console output. Google for how on your particular mobile target, such as this answer or iOS: https://forum.unity.com/threads/how-to-capturing-device-logs-on-ios.529920/ or this answer for Android: https://forum.unity.com/threads/how-to-capturing-device-logs-on-android.528680/

If you are working in VR, it might be useful to make your on onscreen log output, or integrate one from the asset store, so you can see what is happening as you operate your software.

Another useful approach is to temporarily strip out everything besides what is necessary to prove your issue. This can simplify and isolate compounding effects of other items in your scene or prefab.

Here's an example of putting in a laser-focused Debug.Log() and how that can save you a TON of time wallowing around speculating what might be going wrong:

https://forum.unity.com/threads/coroutine-missing-hint-and-error.1103197/#post-7100494

When in doubt, print it out!(tm)

Note: the

print()

function is an alias for Debug.Log() provided by the MonoBehaviour class.
