Preloading is one of the best ways which reduce user’s stress easily.
So, I created the loading.cs for preloading.
If you don’t need animation system, please get rid of below part,
Update(){——-}
Script
using UnityEngine;
using System.Collections;
using UnityEngine.UI;
using UnityEngine.SceneManagement;
public class Loading : MonoBehaviour
{
private AsyncOperation async;
public Text loadingText;
public float waitSec = 5.0f;
public float cycle=0.8f;
float time=0;
void Start()
{
StartCoroutine("LoadData");
}
private void Update()
{
time += Time.deltaTime;
if(time <= (cycle/5f))
loadingText.text = "Now loading";
else if (time <= (cycle * 2 / 5f))
loadingText.text = "Now loading.";
else if (time <= (cycle * 3 / 5f))
loadingText.text = "Now loading..";
else if (time <= (cycle * 4 / 5f))
loadingText.text = "Now loading...";
else if (time <= cycle)
{
time = 0;
}
}
IEnumerator LoadData()
{
// Start loading scene
async = SceneManager.LoadSceneAsync("MainScene");
// Dont activate changing scene when the load finished.
async.allowSceneActivation = false;
while (async.progress<0.9f)
{
yield return null;
}
//change scene after wait some seconds
yield return new WaitForSeconds(waitSec);
async.allowSceneActivation = true;
}
}
Postscript
BTW, be careful about “AsyncOperation”
In this script, preloading work
while (async.progress<0.9f)
but didn't work
while (!asny.isDone)
It's because when you define async.allowSceneActivation = false;
at first,
async.isDone always return false
and
async.progress couldn’t reach 1.0 but 0.9
the max state will be 0.9.
Best regards.
I write this post to improve my English skill. Don’t mind some spelling mistake.
