I'm working on a unity project in which game scene get downloaded and run at run-time. I make it work by making asset-bundle of scene and load it but problem i'm facing is scripts required by scene are not included in asset-bundle. I just got stuck here can anyone please help me that, how i can download/load required scripts or how i can include them in asset-bundle. so that i can load them at run-time also.
Sorry for bad English. Thanks.
You can add any type of asset you want in an asset-bundle.
Script (.cs file) won't be able to be included in an asset-bundle.
The way you can add all scripts/materials/.. you needs, depends on what is included in your scene, is to store them all in a folder. Then you can assign the whole folder to a AssetBundle tag as should your scene be.
Your scene the client needs to download has to be in the same asset-bundle tag.
Note : if you can't store them all in the same folder, just assign their asset-bundle tag manually for each asset (or subfolder) you want to add to the bundle.
Now you can run a method to create the bundle for you, as the following :
[MenuItem("Bundles/Create all bundles")]
static void BuildAllAssetBundles()
{
BuildPipeline.BuildAssetBundles(Path.Combine(Application.dataPath, "AssetBundleLocation"), BuildAssetBundleOptions.None, BuildTarget.StandaloneWindows);
}
There is more information about How to build an asset-bundle.
Now all files required should be store in the asset-bundle file, 'Edit' except script files. Take a look at UnityEngine.AssetBundle class to load and unload bundles/assets.
Edit
What will actually work to include your script file within an asset-bundle is to write your code in a TextAsset file (.txt).
Those files will give you a string once loaded from the asset-bundle.
AssetBundle ab = AssetBundle.LoadFromFile(Path.Combine(Application.dataPath, "StreamingAssets/exampleassetbundle")); // Your asset-bundle path
TextAsset textAsset = ab.LoadAsset<TextAsset>(ab.GetAllAssetNames()[0]); // In my example I only have 1 file in the asset-bundle, the TextAsset
string flatCode = textAsset.text;
Now the thing is, you have to compile the flat string code to an actual C# class. This is called Runtime compilation.
There is many tutorials about how to do it, as this stackexchange post.
It's a bit tricky, but will do what you want.
Note : IOS and Android may not let you compile code at runtime, so depends on your target platform, you will have to investigate further.
The correct way to include programming in your asset bundles is to first compile your code into a dll and reference that dll from your assets. Then add the assets and the dll to the bundle and export it.
