Interaction

A key aspect of this game is its interaction system. The player can interact with doors and collectables.

To ensure scalability, a interface was used to implement the interaction system. A interactionbox is attached to the player, whenever an object that implements the interface enters the box, it will be stored in an actor array. On leaving, it is removed again. When the player presses the interact button, the interface interact function is called on all actors within the array.

AI (State Tree)

The questing beast's behaviour is programmed using Unreal Engine's State Tree system. It has 3 general states: Patrol, Hunt and Rage.

The AI can open and close doors when patrolling. While in hunt or rage mode, it will break them instead. This however stalls it for a short moment. Once the player collects all 5 souls, the AI automatically enters rage mode, and is not only faster, but also knows his position at all times.

Random Item Distribution

Multiple Spawn locations for the collectable souls are pre-defined in the level. A Spawn controller assigns the actual collectables randomly among them.

Escape Door and Level Transition

There are multiple escape doors placed in the level. One of them will be unlocked and activated, once the player has collected all souls. On entering it, the player wins and is given the option to return to the main menu.
