    Hi,

    Im starting in Unity and have set up a script to randomize the background of my levels with an array of background and a sprite renderer. I have 3 total backgrounds. and what Id like to do is still randomize on the first level but on the second level and beyond, I would like it to be random between the two that weren't used on the level just before. Whats the best way to deal with this ?

    What about putting them into an array. Randomize an array index, use the image and remove it from the array. For the next level you only have 2 images left in the array, randomize an array index, use the image and remove it from the array. Now it depends on what you want to do but i think after removing the second image, put the first image back into the array and you have 2 images again for the 3rd level. And so on
