Title: Randomly instantiating sprites in a sprite collection?
Post by: neo750a on December 28, 2013, 01:24:57 am

Is this possible?  Or do i have to make a database myself and store prefabs to achieve this?  It would be immensely helpful if I could as it would cut out alot of what I need done.  What I am trying to do is to display 6 different sprites on 6 random points(one unique sprite each point) on the game view.  Thanks in advance and sorry if this was asked previously.

Create a prefab of a sprite from the sprite collection, instantiate it and then change the sprite Id using something like this:

Code: [Select]

int randomSprite = 0;
do {
  randomSprite = Random.Range(0, sprite.Collection.Count);
} while (!sprite.Collection.spriteDefinitions[randomSprite].Valid);
sprite.SetSprite( randomSprite);

the while loop is necessary in case you have deleted / invalid sprites in your collection.

I have to say, thank very much for the response!  Sorry for the long reply.  This helped me out immensely!
