Game Development Asked by HaPK on November 2, 2021
I need to instantiate different gameObjects of different shapes and sizes on top of the left third and the right third of a table, and all this objects need to be random every time the scene loads. I have a library of around 80 GO but the most I’ll instantiate, for now, is 30. All the instantiated GO have to be different, that means no duplicates.
I thought that maybe I could create 30 empty gameObjects on the table, where I want to instantiate them in random, but I’m not sure if this is the most intelligent way to do it. Is there any other way?
Also, since I have a library of GO so large, would it be possible to load the folder in the script instead of defining a list and populating it in the editor?
I’m a bit new at coding for Unity, but I’m an experienced programmer.
There are multiple ways of doing the instantiation itself:
public static Object Instantiate(Object original, Transform parent);
public static Object Instantiate(Object original, Vector3 position, Quaternion rotation);
When it comes to scanning a given path to find all assets, take a look at the AssetDatabase.FindAssets
helper: https://docs.unity3d.com/ScriptReference/AssetDatabase.FindAssets.html
(You can even filter with specifics asset labels!)
To avoid copying the output list of FindAssets to shuffle it, you can generate a list of randomized indexes using Linq, and then simplify iterate on this index list:
Random rnd = new Random();
List<int> indexes = Enumerable.Range(0, 30).OrderBy((item)=> rnd.Next()).ToList();
Cheers!
