so everything works fine when i am using “transform.position = waypoint.transform.position;”. the enemy then moves from one tile to the other following the path list i have set, but then i try the lerp and it wont move, i added debug to parts of the code and can see they print once each to the console, here is my code.
using System.Collections;
using System.Collections.Generic;
using UnityEngine;
public class EnemyMover : MonoBehaviour
{
//creates list of type waypoint that is our other script, then set path as a new list
[SerializeField] List path = new List();
[SerializeField] float waitTime = 1f;
void Start()
{
Debug.Log("Start");
//This is how a Corutine Method is called
StartCoroutine(FollowPath());
//repeat method and add delay and repeat time
//InvokeRepeating("PrintWaypointName", 0, 1f); - problem with this is that it delays the whole method, we need to dealy steps in the method
Debug.Log("Finish");
}
//set type IEnumerator returns somthing countable the system can use
IEnumerator FollowPath()
{
// go through every object that is in the serialized field of path
foreach(Waypoint waypoint in path)
{
Debug.Log("followapath");
//using vector3.Lerp we first create start and end position
Vector3 startPosition = transform.position;
Vector3 endPosition = waypoint.transform.position;
float travelPercent = 0f;
//this is to update our travelpercent while percent is under 1 because 1 is the end
while(travelPercent < 1f)
{
travelPercent += Time.deltaTime;
transform.position = Vector3.Lerp(startPosition, endPosition, travelPercent);
yield return new WaitForEndOfFrame();
Debug.Log(waypoint.name);
}
//do this with every path object
//Debug.Log(waypoint.name);
//this creates a var that is objects transform object and the position part, then sets that as the current waypoint transform object position value
// this is disabled when we use LERP // transform.position = waypoint.transform.position;
//needs yeald statment when it is a IEnumerator the return a new WaitForSecond(1f) that is value of 1 in wait in second that becomes one second.
// so whe give up control and then we start again in 1 second.
// this is disabled when we use LERP // yield return new WaitForSeconds(waitTime);
}
}
}
