Random object and random sprites?

Questions & Answers
1

I have a game where you check other people bags, I wanted to have a pre-defined layout for the bag and have it randomly picked, I also wanted the items inside the bag to have a random sprite.
Can you help me with the logic for this? I’m thinking about using an array of prefabs

There are a lot of approaches to this, but here is a common one. Of course this should be changed to meet your specific needs.

Setup a list of possible items that can be shown (however you define your items is up to you) and use Random.Range to grab a random index. If each of your items need random sprites too (i.e there aren’t specific sprites to each item) then you can use the same Random.Range to get a random index in a different itemSpriteList.

If you want to use prefabs like mentioned, it could be something like (assuming each of your prefabs have an ‘Item’ script/component attached): [Untested]

[SerializeField]
private List<Item> possibleItems;
[SerializeField]
private List<Sprite> possibleSprites;

// How you assign will depend on how your bag is setup
// This example will assume your Bag has an items list
private void AssignRandom(int x)
{
     // Get a random index from 0 to the length of the list
     bag.items[x] = possibleItems[Random.Range(0,possibleItems.Count)]
     bag.items[x].sprite = possibleSprites[Random.Range(9,possibleSprites.Count)]
}

It’s hard to get an ideal solution without more information about your structure setup, but typically Random.Range is a good way utilize randomization when you don’t need true random.
