What i want it to do is both in the editor and when running the game to see all the Spheres in the same time moving to another direction or maybe it will be the same direction untill endPoint and then back to the startPoint in a loop none stop.
This is my script:
using System;
using UnityEngine;
using Random = UnityEngine.Random;
[ExecuteInEditMode]
public class SphereBuilder : MonoBehaviour
{
// for tracking properties change
private Vector3 _extents;
private int _sphereCount;
private float _sphereSize;
/// <summary>
/// How far to place spheres randomly.
/// </summary>
public Vector3 Extents;
/// <summary>
/// How many spheres wanted.
/// </summary>
public int SphereCount;
public float SphereSize;
private void OnValidate()
{
// prevent wrong values to be entered
Extents = new Vector3(Mathf.Max(0.0f, Extents.x), Mathf.Max(0.0f, Extents.y), Mathf.Max(0.0f, Extents.z));
SphereCount = Mathf.Max(0, SphereCount);
SphereSize = Mathf.Max(0.0f, SphereSize);
}
private void Reset()
{
Extents = new Vector3(250.0f, 20.0f, 250.0f);
SphereCount = 100;
SphereSize = 20.0f;
}
private void Update()
{
UpdateSpheres();
}
private void UpdateSpheres()
{
if (Extents == _extents && SphereCount == _sphereCount && Mathf.Approximately(SphereSize, _sphereSize))
return;
// cleanup
var spheres = GameObject.FindGameObjectsWithTag("Sphere");
foreach (var t in spheres)
{
if (Application.isEditor)
{
DestroyImmediate (t);
}
else
{
Destroy(t);
}
}
var withTag = GameObject.FindWithTag("Terrain");
if (withTag == null)
throw new InvalidOperationException("Terrain not found");
for (var i = 0; i < SphereCount; i++)
{
var o = GameObject.CreatePrimitive(PrimitiveType.Sphere);
o.tag = "Sphere";
o.transform.localScale = new Vector3(SphereSize, SphereSize, SphereSize);
// get random position
var x = Random.Range(-Extents.x, Extents.x);
var y = Extents.y; // sphere altitude relative to terrain below
var z = Random.Range(-Extents.z, Extents.z);
// now send a ray down terrain to adjust Y according terrain below
var height = 10000.0f; // should be higher than highest terrain altitude
var origin = new Vector3(x, height, z);
var ray = new Ray(origin, Vector3.down);
RaycastHit hit;
var maxDistance = 20000.0f;
var nameToLayer = LayerMask.NameToLayer("Terrain");
var layerMask = 1 << nameToLayer;
if (Physics.Raycast(ray, out hit, maxDistance, layerMask))
{
var distance = hit.distance;
y = height - distance + y; // adjust
}
else
{
Debug.LogWarning("Terrain not hit, using default height !");
}
// place !
o.transform.position = new Vector3(x, y, z);
}
_extents = Extents;
_sphereCount = SphereCount;
_sphereSize = SphereSize;
}
}
Update
I created another c# script and dragged it to the Terrain.
using UnityEngine;
using System.Collections;
public class MoveSpheres : MonoBehaviour {
public Transform _transform;
private Vector3 pos1 = new Vector3(-4,0,0);
private Vector3 pos2 = new Vector3(4,0,0);
public float speed = 1.0f;
// Use this for initialization
void Start () {
}
// Update is called once per frame
void Update () {
_transform.position = Vector3.Lerp (pos1, pos2, Mathf.PingPong(Time.time*speed, 1.0f));
}
}
This script move one Sphere. But i want to move all the Spheres. And also if i change in the first script the number of Spheres then move them too keep move them too.
The problem is with the Destroy part in the first script.
