Unity Extensions

Here we have extension methods for Unity objects (GameObject, Vector3, etc.). These add useful functionality that I often end up reimplementing in every game I make.

Usage

Add the scripts to your Unity project wherever you see fit. The classes are in the Extensions namespace, so you must first import them with the using keyword.

using Extensions;

Now call the extensions on the appropriate object type.

void Awake ()
{
    var someComponent = gameObject.GetOrAddComponent<MyComponent>();
}

Included Extensions

The extensions here are a work in progress.

Component

someComponent.AddComponent<MyComponent>();

someComponent.GetOrAddComponent<MyComponent>();

someComponent.HasComponent<MyComponent>();

GameObject

gameObject.GetOrAddComponent<MyComponent>();

gameObject.HasComponent<MyComponent>();

NetworkPlayer

Network.player.GetIndex();

Rigidbody

// Change direction of movement without modifying speed.
rigidbody.ChangeDirection(Vector3.right);

Transform

// Make array of game objects children of this transform.
transform.AddChildren(someGameObjects);

// Set children of this transform to position (0, 0, 0).
transform.ResetChildPositions();

transform.SetChildLayers("Ignore Raycast");

Vector3

// Find closest position.
var otherPositions = someTransforms.Select(t => t.position);
transform.position.GetClosest(otherPositions);

Vector3Int

// Convert `Vector3Int` struct to `Vector3`.
var vector = new Vector3Int(1, 2, 3);
var vector3 = vector.ToVector3();
