Summary of "Input manager - City Builder Unity tutorial P4"

In this tutorial video, the speaker demonstrates how to implement an Input Manager for a City-Building Game using Unity. The Input Manager is designed to capture player input, allowing them to select spaces on a map and place structures. Additionally, it enables Camera Movement using arrow keys to navigate the entire map.

Key Features and Concepts:

Input Manager Creation: The tutorial begins by creating a new script for the Input Manager and setting up Action Delegates to handle player interactions.
Action Delegates:
- onMouseClick: Triggered when the player clicks on the map.
- onMouseHold: Used to track mouse movement while holding down the button, particularly for creating roads and recalculating paths.
- onMouseUp: Triggered when the mouse button is released.
Camera Movement: A property for Camera Movement is created to allow for navigation across the game map.
Raycasting: The Input Manager uses Raycasting to determine if the player has clicked on the correct layer (ground) of the map.
Input Handling: The Update method checks for mouse clicks, mouse holds, and arrow key inputs to manage player interactions and Camera Movement.

Implementation Steps:

Create the Input Manager script and set up Action Delegates.
Implement methods to check for mouse events (click down, click up, and click hold) and arrow key inputs.
Use Raycasting to determine the clicked position on the map.
Integrate the Input Manager with the Unity game object system.

The video concludes by indicating that the next part will involve creating a Game Manager that will utilize the Action Delegates to perform actions based on player input.
