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)
