### BIGAL Achievement Definition Example

Source: https://github.com/mcparks/achievables/blob/main/README.md

An example of a complete achievement definition using BIGAL version 0, including state, activators, deactivators, and event handling.

```Groovy
achievement {
    syntaxVersion 0
    name "Magic Kingdom Mountaineer"
    description "Ride the three mountains of Magic Kingdom without warping or teleporting"
    icon "IRON_SPADE:20"
    reward "MONEY:500"

    state {
        rodeSpaceMountain = false
        rodeBigThunderMountain = false
        rodeSplashMountain = false
        warpedOrTeleported = false
    }

    activators {
        (state.rodeSpaceMountain == true) && (state.rodeSplashMountain == true) && (state.rodeBigThunderMountain == true)
    }

    deactivators {
        state.warpedOrTeleported == true
    }

    events {
        on("CompleteRideEvent") {
            if (event.rideId == 32) {
                state.rodeSpaceMountain = true
            }
            if (event.rideId == 7) {
                state.rodeBigThunderMountain = true
            }
            if (event.rideId == 9) {
                state.rodeSplashMountain = true
            }
        }
        on("TeleportPlayerToPlayerEvent") {
            state.warpedOrTeleported = true
        }
        on("PlayerWarpEvent") {
            state.warpedOrTeleported = true
        }
    }
}
```

### Activator Logic Example

Source: https://github.com/mcparks/achievables/blob/main/README.md

Defines the conditions under which an achievement is considered complete. It uses boolean logic to evaluate the game state.

```groovy
activators {
    (state.rodeSpaceMountain == true) && (state.rodeSplashMountain == true) && (state.rodeBigThunderMountain == true)
}
```

--------------------------------

### AchievableManager Process Trigger Implementation

Source: https://github.com/mcparks/achievables/blob/main/README.md

Provides an example implementation of the `processTrigger` method within the AchievableManager. This method iterates through registered achievables matching the trigger type and attempts to process the trigger against each achievable.

```java
// In your AchievableManager implementation
@Override
public void processTrigger(AchievableTrigger trigger) {
    // Check if the trigger matches any registered achievements
    for (Achievable achievable : registeredAchievables.get(trigger.getType())) {
        try {
            achievable.process(trigger);
        } catch (Exception e) {
            // do whatever you want with caught exceptions
        }
        
    }
}
```

--------------------------------

### Deactivator Logic Example

Source: https://github.com/mcparks/achievables/blob/main/README.md

Defines the conditions under which an achievement's progress should be reset. It uses boolean logic to evaluate the game state.

```groovy
deactivators {
    state.warpedOrTeleported == true
}
```

--------------------------------

### Initialize Achievables System

Source: https://github.com/mcparks/achievables/blob/main/README.md

Achievables.getInstance().setLogger(yourLogger);

Achievables.getInstance().setAchievableMetaBuilderSupplier(() -> YourAchievementMeta.builder());

Achievables.customizeGson(gsonBuilder -> 
    gsonBuilder.registerTypeAdapter(AchievablePlayer.class, new YourPlayerDeserializer()));
Achievables.customizeGson(gsonBuilder -> 
    gsonBuilder.registerTypeAdapter(AchievablePlayer.class, new YourPlayerSerializer()));
```

--------------------------------

### Load and Register BIGAL Achievements

Source: https://github.com/mcparks/achievables/blob/main/README.md

Shows how to load achievement definitions from BIGAL files, parse them, and register the parsed achievables with the AchievableManager. It also mentions the utility of metadata associated with achievables.

```java
import java.util.List;

List<String> bigAlFileContents = // Load your BIGAL files;

for (String fileContent : bigAlFileContents) {
    // Parse the BIGAL file content
    AchievableWithMeta parsedAchievable = BigalsIntegratedGroovyAchievementLanguage.interpret(fileContent);
    //
    
    // Register the achievable with your manager
    yourAchievableManager.registerAchievable(parsedAchievable.getAchievable());

    // you might want to use the metadata for other purposes! We use it to display the achievement in the GUI, keep track of the rewards, determine whether or not the file should be activated, etc.
}
```

--------------------------------

### Player Representation and Serialization

Source: https://github.com/mcparks/achievables/blob/main/README.md

Shows how to create a `YourPlayer` class implementing `AchievablePlayer` and provide custom `JsonSerializer` and `JsonDeserializer` for `AchievablePlayer`.

```java
public class YourPlayer implements AchievablePlayer {
    // Player implementation
}
```

```java
public class YourPlayerSerializer implements JsonSerializer<AchievablePlayer> {
    @Override
    public JsonElement serialize(AchievablePlayer player, Type type, JsonSerializationContext context) {
        // Convert YourPlayer to JSON
    }
}
```

```java
public class YourPlayerDeserializer implements JsonDeserializer<AchievablePlayer> {
    @Override
    public AchievablePlayer deserialize(JsonElement json, Type type, JsonDeserializationContext context) {
        // Convert JSON to YourPlayer
    }
}
```

--------------------------------

### State Persistence Implementation

Source: https://github.com/mcparks/achievables/blob/main/README.md

Provides the methods `setPlayerState` and `getPlayerState` for implementing the storage and retrieval of achievement states for players.

```java
@Override
public void setPlayerState(AchievablePlayer player, StatefulAchievable achievable, Map<String,Object> state, boolean persist) {
    // Store the player's state for the achievable
    // If persist is true, save to your persistent storage (database, etc)
}
```

```java
@Override
public Map<String,Object> getPlayerState(AchievablePlayer player, StatefulAchievable achievable) {
    // Retrieve the player's state for the achievable from your storage
}
```

--------------------------------

### Event System Implementation

Source: https://github.com/mcparks/achievables/blob/main/README.md

Illustrates defining custom game events that extend `us.mcparks.achievables.events.Event` and mapping event class names to these custom events within the `AchievableManager`.

```java
public class YourGameEvent implements us.mcparks.achievables.events.Event {
    // Event implementation
}
```

```java
public class YourPlayerJumpEvent extends YourGameEvent {
    // Player jump event implementation
}
```

```java
public class YourItemCollectEvent extends YourGameEvent {
    // Item collect event implementation
}
```

```java
@Override
public Class<? extends Event> getEventClass(String eventClassName) {
    // Map event class names to your game's event classes
    switch(eventClassName) {
        case "PlayerJumpEvent": return YourPlayerJumpEvent.class;
        case "ItemCollectEvent": return YourItemCollectEvent.class;
        // Add more mappings as needed (more likely: do this dynamically with reflection)
        default: return null;
    }
}
```

--------------------------------

### Register and Unregister Achievables

Source: https://github.com/mcparks/achievables/blob/main/README.md

Demonstrates how to register and unregister achievables with the AchievableManager, using a Multimap to index them by trigger type. This is crucial for efficient event handling.

```java
import com.google.common.collect.HashMultimap;
import com.google.common.collect.Multimap;
import com.google.common.collect.Multimaps;

// in your AchievableManager
Multimap<AchievableTrigger.Type, Achievable> achievables = Multimaps.synchronizedSetMultimap(HashMultimap.create());

public void registerAchievable(Achievable achievable) {
        for (AchievableTrigger.Type triggerType : achievable.getTriggers()) {
            //System.out.println("Registering achievable " + achievable.getUUID().toString() + "with trigger " + triggerType.toString());
            achievables.put(triggerType, achievable);
        }
    }

public void unregisterAchievable(Achievable achievable) {
    for (AchievableTrigger.Type triggerType : achievable.getTriggers()) {
        achievables.remove(triggerType, achievable);
    }
}
```

--------------------------------

### BIGAL Achievement Metadata

Source: https://github.com/mcparks/achievables/blob/main/README.md

Defines the metadata for an achievement, including syntax version, name, description, icon, and reward.

```Groovy
syntaxVersion 0
name "Magic Kingdom Mountaineer"
description "Ride the three mountains of Magic Kingdom without warping or teleporting"
icon "IRON_SPADE:20"
reward "MONEY:500"
```

--------------------------------

### BIGAL Achievement State Variables

Source: https://github.com/mcparks/achievables/blob/main/README.md

Defines the initial state variables for an achievement, which track player progress and disqualifying conditions.

```Groovy
state {
    rodeSpaceMountain = false
    rodeBigThunderMountain = false
    rodeSplashMountain = false
    warpedOrTeleported = false
}
```

--------------------------------

### Java Implementation of AchievableManager

Source: https://github.com/mcparks/achievables/blob/main/README.md

Provides a basic structure for a Java class that implements the AchievableManager interface, required for managing achievements.

```java
public class YourAchievableManager implements us.mcparks.achievables.AchievableManager {
    // Implementation of required methods
    // ...
}
```

--------------------------------

### Achievement Completion Tracking

Source: https://github.com/mcparks/achievables/blob/main/README.md

Details the implementation of `completeAchievable` to mark an achievement as completed and `isCompleted` to check the completion status for a player.

```java
@Override
public void completeAchievable(Achievable achievable, AchievablePlayer player) {
    // Mark the achievable as completed for the player
    // Store this information in your persistent storage (database, etc)
    // Trigger any rewards or notifications
}
```

```java
@Override
public boolean isCompleted(Achievable achievable, AchievablePlayer player) {
    // Check if the player has completed the achievable
}
```

--------------------------------

### Process Game Events to Triggers

Source: https://github.com/mcparks/achievables/blob/main/README.md

Illustrates how to convert a game event into an AchievableTrigger and then process this trigger using the AchievableManager. This is the core mechanism for triggering achievements based on game occurrences.

```java
// In your event handling system
public void onYourGameEvent(YourGameEvent event) {
    // Convert to an Achievable Trigger
    AchievableTrigger trigger = new AchievableTrigger(
        AchievableTrigger.Type.EVENT, 
        event,
        (YourPlayer) event.getPlayer()
    );
    
    // Process the trigger
    yourAchievableManager.processTrigger(trigger);
}
```

--------------------------------

### Event Handling for State Changes

Source: https://github.com/mcparks/achievables/blob/main/README.md

Responds to game events to update the achievement's state. It checks event-specific fields like 'rideId' and modifies the 'state' object accordingly.

```groovy
events {
    on("CompleteRideEvent") {
        if (event.rideId == 32) {
            state.rodeSpaceMountain = true
        }
        if (event.rideId == 7) {
            state.rodeBigThunderMountain = true
        }
        if (event.rideId == 9) {
            state.rodeSplashMountain = true
        }
    }
    on("TeleportPlayerToPlayerEvent") {
        state.warpedOrTeleported = true
    }
    on("PlayerWarpEvent") {
        state.warpedOrTeleported = true
    }
}
```
