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.

Installing

Add the package to your project via UPM using the Git URL https://github.com/mminer/unity-extensions.git. You can also clone the repository and point UPM to your local copy.

Using

The classes are in the UnityExtensions namespace, so you must first import them.

using UnityExtensions;

Now call the extensions on the appropriate object type.

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

Included Extensions

Component

someComponent.AddComponent<MyComponent>();

someComponent.GetOrAddComponent<MyComponent>();

someComponent.HasComponent<MyComponent>();

GameObject

gameObject.GetOrAddComponent<MyComponent>();

gameObject.HasComponent<MyComponent>();

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();
