Asset bundle

Learn to load large assets in chunks with AssetBundle.

What is AssetBundle?

An AssetBundle is a structure that carries game assets in a single package file. Instead of loading large assets all at once at the start of the game, you can load them part by part with AssetBundles. This way the amount of data held in memory at one time decreases.

AssetBundle paket = AssetBundle.LoadFromFile("dolap");

The package is opened and used as the assets are needed.

Streaming

Streaming is loading assets as a stream and only when they are needed. A section the player will not see right away can be loaded later. This way both loading time and memory load are shared.

string paketAdi = "SahneVarligi";
int parcaSayisi = 3;

Loading in parts is essential for large games.

Exercise Keep a package record

In a class named VarlikYukleme, define a string field named paketAdi with the value "SahneVarligi" and an integer field named parcaSayisi with the value 3. In the Start method print the pieces "Paket: ", paketAdi, " Parca: " and parcaSayisi joined together with Debug.Log.

Show example solution

using UnityEngine;

public class VarlikYukleme : MonoBehaviour
{
    string paketAdi = "SahneVarligi";
    int parcaSayisi = 3;

    void Start()
    {
        Debug.Log("Paket: " + paketAdi + " Parca: " + parcaSayisi);
    }
}
