Getting Started

Blackboard

The blackboard is an esential part of Mallos.Ai, it is a central place to store and look up data related to the BehaviorTree.

As some BehaviorTree nodes require time to function there is a ElapsedTime property on the Blackboard which defined how long time it took since the last call. If you are making a turned based game it's a good idea to make it a constant time which is counted every turn.

The Blackboard also have a directory for storing anything that the nodes might want to share data between them. In the example below we store the coordinates where the player was seen and in the NavigateNode we say nagivate to those coordinates.

Create BehaviorTree

File: GoRogueSample/Monsters/Monster.cs

new BehaviorTree(
    new ParallelSequenceNode(
        // Check if we can see the player.
        new EnvironmentQueryNode(
            entity => FOVRadius,            // Entity View Radius.
            entity => entity is Player,     // Check if it is a player.
            spottedKey: "SeePlayer",        // Set a blackboard property with true or false.
            spottedCoordKey: "WalkTo"       // Set a blackboard property with the found coords.
        ),
        new ConditionalNode(
            blackboard => blackboard.GetProperty<bool>("SeePlayer"),
            new NavigateNode("WalkTo"),     // Go to Player
            new WanderNode()                // Wander around
        )
    )
);
