Description

Initializer that configures spawned entities with random direction.

RandomDirectionInitializer generates a random 2D direction and applies it to the entity's DirectionComponent and Move2DComponent. This is useful for spawning enemies that should move in unpredictable directions.

Components affected:

• **DirectionComponent:** Sets random normalized direction
• **Move2DComponent:** Sets move intent in the random direction

info

Uses a static Random generator with a fixed seed for reproducibility.
