Introduction

Mouse Manager

Demonstrated who to do a mouse manager which determines what the cursor should look like when interaction with an object occurs. To do this they

• Create game object called Mouse Manager
• Set up a script which exposes 5 different Texture2d textures extending monobehaviour
• Implement update which is fired for each frame
• Import assets for cursors, set the texture type to cursor
• Attach Script to Mouse Manager object
• Drag drop assets to Mouse Manager slots from script
• Make an new layer and name it clickable
• Go to mouse manager and say clickable is possible on clickable layer

Movement

This was quite complex (maybe first time around)

• Import the NavMeshComponents
• Add NavMesh Surface empty game object
• Set the agent type on NavMesh Surface Object
• Pressing bake shows what cannot move
• We need to exclude the player from this
• To exclude the player we need to
  • On the mesh exclude the player layer
  • On the Player object assign the player layer to the player object
• Next create a player controller class in a script which has an agent and within start() we get this agent with GetComponent<NavMeshAgent>()
• Back in the mouseManager script create a delegate for EventVector3 OnClickEnvironment
• In the clickable if statement call the function assigned to the delegate from the GUI

if(input.GetMouseButtonDown(0)) {
   OnClickEnvironment.Invoke
}

• The assign the NavMeshAgent destination to the OnClickEnvironment

Player Interactions

We can capture and change the destination on collision

// Can store the data with a collision
// Assign the new co-ordinates 
Transform doorway = hit.collider.gameObject.transform
OnClickEnvironment.Invoke(doorway.position)

NPC Patrol

Basically wrote a script to move to the two waypoints (a reference point used for navigation purposes by in-game characters)

• Create an NPC new game object
• Create the waypoints (new gameobject) under the NPC
• Create a script
• Assign the waypoints to the script

public class NPCController : MonoBehaviour
{
    public float patrolTime = 10f;
    public float aggroRange = 10f;
    public Transform[] waypoints;

    private int index;
    private float speed, agentSpeed;
    private Transform player;

    //private Animator anim;
    private NavMeshAgent agent;

    private void Awake()
    {
        //anim = GetComponent<Animator>();
        agent = GetComponent<NavMeshAgent>();
        if (agent != null) { agentSpeed = agent.speed; }
        player = GameObject.FindGameObjectWithTag("Player").transform;
        index = Random.Range(0, waypoints.Length);

        InvokeRepeating("Tick", 0, 0.5f);

        if(waypoints.Length > 0)
        {
            InvokeRepeating("Patrol", 0, patrolTime);
        }
    }

    void Patrol()
    {
        index = index == waypoints.Length - 1 ? 0 : index + 1;
    }

    void Tick()
    {
        agent.destination = waypoints[index].position;
        agent.speed = agentSpeed / 2;

        if(player != null && Vector3.Distance(transform.position, player.position) < aggroRange)
        {
            agent.destination = player.position;
            agent.speed = agentSpeed;
        }
    }
}

Level Design

Using Probuilder

With probuilder we need to import the tools probuilder and progrids. From there we are able to create a scene which represents the artwork.
And use the probuilder tool to build a similar look.
