This is an update to a project we submitted for the "Introduction to Unity" course. It has become rather large by now so we could not show all features in the short lets play video. Therefore, and in order for the evaluators of the course to differentiate what we added for the advanced experiment design course, we wrote a short update report explaining our new features:

We created a system to include autonomous NPCs in our game. Our system implements a finite state machine. Each NPC in the game has a NPC script that inherits from the abstract NPC Base Class and controlls the initialization of the npc/states, the animations, and keeps track of the current state of the NPC. There exist NPC scripts for Sheep NPCs and Citizens which implement specific behavious and animations. We decided to implement the possible states as components. There exists an abstract NPCState Baseclass that each specific state inherits from. Central to each state is that it implements a state action that is executed if the NPC is in the state and a state transition that defines the conditions for transitioning from the state into other states. This way all the states an NPC has define a transition graph. We tried to build the states as modular as possible such that the game designer can pick a subset of them and give them to a new npc class without having to adapt each state. The states we implemented are:

• Idle State: All states transition into idle state if they are "done".
  • There is a specific Idle state for the citzen (Idle Citizen) and the sheep (wander state).
• Avoid State: In this state the NPC avoids a certain game object. All states have the option to transition into the avoid state if the NPC has this state component and objects to avoid are assigned.
• Follow State: The NPC follows a target object at some distance.
• Perform Task State: The NPC performs a set of tasks
  • NPC needs a Task Controller that manages the set of tasks
  • Task Objects need the NPCTask script as a component.
• Meet NPC State: The NPC meets another NPC, stops for an interaction, and continues after some time
• Meet Player State: The NPC greets the player and stops for an interaction For details of the system refer to our scripts in the "Agents" folder.

We used our NPC system to create Flocks of sheep that patrol around the scene and inbetween patrols graze at a local spot. They also avoid the player.

The second big thing we used the system for is to create citizens for our new village and the new city. The Citizens walk around and perform tasks either at their personal farm or at the public places. They meet eachother if they get close and they stop to greet the player.

We added animations of certain actions for both the Player and the NPCs. Added animations are:

• Weeding
• Harvesting
• Watering
• Digging
• Planting
• Pick Up
• Working (NPC only)
• Greeting (NPC only)
• Walking (NPC only)

We also added an animated Ocean

Additional Assets used for animation:

• RPG Character Mecanim Animation Pack FREE
• LowPolyWater_Pack
• Mixamo Magic Pack
• Supercyan Character Pack Free Sample

We developted a Dialouge System that enables the Player to talk to an NPC (or other Gameobject) We developed a Quest System. Through a Dialouge the Player can receive, accept and complete a Quest.

We added a Startscreen and the possibility to pause and quit the game

We added a Minimap to the UI to give the Player a better overview of their position in the game.

Finally we extended our game world to incorporate all of our added features and changes. We added a Village and a City with autonomous NPCs, created a simple collection question, and added some NPCs that talk to the player and give them some information about the game. Everything is build such that it can be scaled up and new NPCs, Quests and Dialouges can be added easily.

Additional Assets used for World building:

• LowPolyBrickHouses

Additionally to those major additions we also fixed bugs in the old version and made some more minor adjustments
