What are some examples of raycasting in Unity?

Raycasting in Unity is used for detecting objects in a scene. For example, you can use it for shooting mechanics or to determine if a player can see an object.

Can you give me a specific code example?

Sure! Here's a simple example:

if (Physics.Raycast(transform.position, transform.forward, out RaycastHit hit, 100f)) {
    Debug.Log("Hit: " + hit.collider.name);
}

This code checks if there's an object in front of the player within 100 units.

What are some common use cases for raycasting?

Common use cases include shooting mechanics, line of sight checks, and detecting ground beneath a character.

How can I visualize raycasting in the Unity editor?

You can visualize raycasting by using Debug.DrawRay in your code. It will draw a line in the Scene view to show the ray's path.
