Uploading and Downloading Prefabs Instantiated at Runtime

Upload-and-Download-Prefabs-Instantiated-at-Runtime-with-ES3Cloud Download

This example is based on the Saving and Loading Prefabs Instantiated at Runtime example, so it is recommended that you familiarise yourself with this example first.

Instead of having the ES3CloudPrefabManagers save their own state, we instead create an ES3CloudManager which calls the Save() and Load() methods on the ES3CloudPrefabManagers, and Uploads and Downloads that data using ES3Cloud.

Note:

You will need to open the ES3CloudManager.cs file and replace the URL and API Key with those of your own server.
Easy Save should be installed in your project before importing this example. The example is located in Assets/Easy Save 3/Examples/.
All examples are only provided as an educational sample, and may need modification for your purposes. They are provided without warranty.
