Load game with Canvas button

You can get the name of the active scene you a currently in with SceneManager.GetActiveScene

https://docs.unity3d.com/540/Documentation/ScriptReference/SceneManagement.SceneManager.GetActiveScene.html

Remeber to add

using SceneMangement;

in the name space.

it actually gets the scene as a reference- so if you want to get the scenes name - i would say public void SaveGame{

string LastSceneName = SceneManagement.GetActiveScene().name;

}

then if its litearlly just the scene name that you need to to save and nothing else, the easiest way to save data is playerprefs. it sounds like you are doing a small project, and if so, i think player prefs might be fine for your purposes, although for a larger project saving data can be more intricate.

https://docs.unity3d.com/ScriptReference/PlayerPrefs.html

heres the docs for player prefs, but ultimatly what you want to do is in the save method i wrote, add somthing like

PlayerPrefs.SetString("SavedSceneName", lastSceneName);

Then just drag and drop the object this method is on to the button's OnClick panel in the inspector. You can load the game with somthing like

public void LoadGame(){

string LoadLevelName = PlayerPrefs.GetString("SavedSceneName", "No Name");

if (LoadLevelName == "No Name"){

Debug.Log("Somthing wierd has gone on, check the name of the scene you tried to save - check the build order, this shouldnt really happen");

} else {

SceneManager.LoadScene(LoadLevelName, LoadSceneMode.Single);

}
