# Save and Load API

Mad Level Manager gives you great control over saving & loading your game with ability to create multiple player profiles. These options are available using MadLevelProfile class.

Saving and loading is done constantly when something changes using the API. Think about saves as of book of memories. Each time something new happens you write a memo into this book. You can write into it constantly so that a player can go back to the place he left the game.

All saving and loading is based on properties. Properties are key-value pairs that you can set for each level or profile-scoped. For example profile-scoped will be a player name, but probably for each level you’ll want to set the highest score achieved. Properties can be saved with these types:

- boolean
- integer
- float
- string

Each of these types has appropriate getrers and setters defined in MadLevelProfile class.

## Relation With Icons

Save & Load system is strongly integrated with level select screens*. Each level has properties such as locked and completed or may contain something custom like collected stars. You can set these properties easily and the saved state will be automatically loaded and displayed on level select screen.

Normally you can store any number of properties for your levels, but decide that only few of them will have representation on level select screen. You can define these properties for your icon prefab and in result it will look similar to this:

Remember that all of these properties are boolean type, and you should use MadProfile.SetLevelBoolean() method to change them. For instance if I want to gain first star for my Level 1 I must write something like this:

    MadLevelProfile.SetLevelBoolean("Level 1", "star_1", true);

Or if you are in Level 1 already you can:

    MadLevelProfile.SetLevelBoolean(MadLevel.currentLevelName, "star_1", true);

Notice that all level names in the Hierarchy are equal to the level names defined in your level configuration.
Property object names must be equal to stored property names, be careful not to make a typo here!

## Common Workflow

MadProfile class is defined in `MadLevelManager` namespace, so don’t forget to put this at the top of your C# file:

    using MadLevelManager;

### Profiles

By default there is a profile called default, so if you don’t need to create more profiles this one will work fully transparent.

#### Creating a New Profile

    MadLevelProfile.RegisterProfile("MyProfileName");

#### Removing existing profile

Will also remove all progress information.

    MadLevelProfile.UnregisterProfile("MyProfileName");

#### Getting/setting current profile

    MadLevelProfile.profile = "MyProfileName";
    Debug.Log("Current profile is " + MadLevelProfile.profile);

#### Listing existing profiles

    Debug.Log("Existing profiles: " + MadLevelProfile.profileList);

### Properties

#### Acquiring a current level star

(Only if level icon has a star_1 property)

    MadLevelProfile.SetLevelBoolean(MadLevel.currentLevelName, "star_1", true);

#### Completing current level

    MadLevelProfile.SetCompleted(MadLevel.currentLevelName, true);

#### Unlocking selected level

    MadLevelProfile.SetCompleted("Level name to unlock", true);

#### Getting/setting custom level property

    MadLevelProfile.SetLevelInteger(MadLevel.currentLevelName, "top score", 9999);
    int topScore = MadLevelProfile.GetLevelInteger(MadLevel.currentLevelName, "top score");

#### Getting/setting custom profile-scoped property

    MadLevelProfile.SetProfileString("player name", "Suzane");
    string playerName = MadLevelProfile.GetProfileString("player name");
